How do we compare writing with and without cards?

At the same writing position, the same model produces one first result with cards and one without. All 280 pairs enter the overall anonymized review, which assesses whether a decision not to continue fits the draft.

Overall: 138 with-card wins, 26 ties, 107 no-card wins, 5 pairs where neither was usable, and 4 inconclusive judgments. Both sides wrote text in 218 pairs; 48 had a deliberate stop and 14 included an invalid output.

HOW DOES BLIND JUDGING WORK?

① Anonymize both outputs
The AI judge sees the same draft and both first outputs without knowing which received cards.

② Compare and swap order
The judge applies task-specific criteria in X/Y and then Y/X order.

③ Review disagreements
A third pass resolves disagreements. Incomplete reviews remain in the denominator.

How are positions and cards selected?

We selected 40 writing positions in each of seven fields, for 280 comparisons. The position and relevant literature cards were set before each comparison, so both versions began from the same draft.

The main result retains every frozen position, including places where cards might not add a useful next move. This avoids selecting cases based on their outputs, but 49% describes the whole cohort, not a win rate where evidence clearly had an opportunity to help. This cohort did not record that opportunity label for each position before generation, so those two groups cannot yet be separated reliably.

CARD USE · 140/280

Reported card use in continuations with text

The model reports whether a card affected its continuation. In 140 of 280 tests it produced continuation text and reported card use. The previous count of 150 included 10 cases without continuation text and has been corrected.

COMPARISON · 70 / 7 / 30

Which written version was better?

Of the 107 reported-use cases where both versions produced text, the blinded AI judge preferred the with-card version 70 times, found 7 about the same, and preferred the without-card version 30 times.

How are the two table percentages calculated?

The percentages use different groups: 50% counts continuations with text reporting card use among all 280 tests; 65% covers the 107 such cases with text on both sides. The generating model reports card use, while an anonymized AI judge compares writing quality.

Card use is self-reported by the generator. The anonymized AI judge sees the draft and source snippets, so source-aware preference remains possible; there was no independent human review. The overall result describes these 280 frozen positions, not a win probability for any writing task.

Long-time continuum limits for twisted Schr\"{o}dinger lattices

Introduction / related work

metric phases and suppression of optical tunneling have also been observed experimentally [35]. Although (1) is conjugate to the cubic NLS by (6), this time-dependent translation has no direct analogue for (2). Consequently, our analysis must address this nonautonomous lattice dynamics. Our proof combines Birkhoff coordinates and modified energies to control the propagation and size of the consistency error in the nonlinear comparison. We exploit the complete integrability of cubic NLS through its Birkhoff representation as coordinatewise rotations [ 19, 24], using their action-dependent frequencies and the regularity of the coordinate maps to derive linear bounds of the tangent flow. A related Birkhoff argument for Strang splitting appears in [18]. Since the lattice approximation does not preserve this integrable structure, we use modified energies to control its Sobolev growth. In [ 12], modified energies based on higher time derivatives yield polynomial discrete Sobolev bounds for an exponential-in-time continuum-limit estimate, motivating our optimized error bounds. To accommodate fractional Sobolev regularities, we adapt the Fourier-side modified-energy construction of [ 5] to

Read overall AI review rationale

A = without cards · B = with cards

The draft is in the middle of explaining a technical methodology: it has introduced Birkhoff coordinates for cubic NLS, noted that lattice approximation breaks integrability, discussed modified energies from [12] for polynomial discrete Sobolev bounds, and begun to describe adapting 'the Fourier-side modified-energy construction of [5] to...' This sentence clearly needs completion to specify what [5]'s construction is being adapted to. Output A completes this naturally: 'the discrete setting, where the modified energy is defined through the discrete Fourier transform and its associated multipliers.' This is accurate and well-scoped — it specifies the target domain (discrete setting), the object being constructed (modified energy), and the technical mechanism (discrete Fourier transform with multipliers), consistent with the fractional Sobolev context and the source [5] being a Fourier-side construction. The phrase 'discrete Fourier transform and its associated multipliers' appropriately generalizes the Fourier-side approach to the lattice without overreaching. Output B says 'the discrete setting, where the nonautonomous lattice dynamics precludes a direct Birkhoff reduction.' This is problematic in context: the draft has already explicitly stated that 'the lattice approximation does not preserve this integrable structure' and that 'we use modified energies to control its Sobolev growth.' The nonautonomous issue was raised earlier regarding equation (2) vs. (1), but at this specific position, the sentence is about adapting [5]'s modified-energy construction. Output B introduces a redundant, somewhat misplaced clause about Birkhoff reduction that doesn't follow grammatically or argumentatively from 'adapt...to.' The construction being adapted is a modified energy, not a Birkhoff argument; saying the dynamics 'precludes a direct Birkhoff reduction' is a non-sequitur at this position and disrupts the logical flow from [5] to the discrete adaptation. Output A maintains coherent methodology progression: Birkhoff for NLS → modified energies for lattice → specific adaptation of [5]'s Fourier construction. Output B derails into repeating an already-established limitation about Birkhoff methods rather than completing the adaptation description.

Card 1 · Bounds on the growth of high discrete Sobolev norms for the cubic discrete nonlinear Schr{\"o}dinger equations on $h\mathbb{Z}$

We consider the discrete nonlinear Schr{\"o}dinger equations on a one dimensional lattice of mesh h, with a cubic focusing or defocusing nonlinearity. We prove a polynomial bound on the growth of the discrete Sobolev norms, uniformly with respect to the stepsize of the grid. This bound is based on a…

Using continuation methods from the integrable Ablowitz-Ladik lattice, we have studied the structure of numerically exact mobile discrete breathers in the standard Discrete Nonlinear Schrodinger equation. We show that, away from that integrable limit, the mobile pulse is dressed by a background of resonant plane waves with wavevectors given by a certain selection rule. This background is seen to be essential for supporting mobile localization in the absence of integrability. We show how the variations of the localized pulse energy during its motion are balanced by the interaction with this background, allowing the localization mobility along the lattice.

Card 3 · Discrete Nonlinear Schrodinger Equations Free of the Peierls-Nabarro Potential

We derive a class of discrete nonlinear Schr{ö}dinger (DNLS) equations for general polynomial nonlinearity whose stationary solutions can be found from a reduced two-point algebraic problem. It is demonstrated that the derived class of discretizations contains subclasses conserving classical norm or a modified norm and classical momentum. These equations are interesting from the physical standpoint since they support stationary discrete solitons free of the Peierls-Nabarro potential. As a consequence, even in highly-discrete regimes, solitons are not trapped by the lattice and they can be accelerated by even weak external fields. Focusing on the cubic nonlinearity we then consider a small perturbation around stationary soliton solutions and, solving corresponding eigenvalue problem, we (i) demonstrate that solitons are stable; (ii) show that they have two additional zero-frequency modes responsible for their effective translational invariance; (iii) derive semi-analytical solutions for …

Card 4 · Statistical mechanics of general discrete nonlinear Schr{ö}dinger models: Localization transition and its relevance for Klein-Gordon lattices

We extend earlier work [Phys.Rev.Lett. 84, 3740 (2000)] on the statistical mechanics of the cubic one-dimensional discrete nonlinear Schrodinger (DNLS) equation to a more general class of models, including higher dimensionalities and nonlinearities of arbitrary degree.

We extend earlier work [Phys.Rev.Lett. 84, 3740 (2000)] on the statistical mechanics of the cubic one-dimensional discrete nonlinear Schrodinger (DNLS) equation to a more general class of models, including higher dimensionalities and nonlinearities of arbitrary degree. These extensions are physically motivated by the desire to describe situations with an excitation threshold for creation of localized excitations, as well as by recent work suggesting non-cubic DNLS models to describe Bose-Einstein condensates in deep optical lattices, taking into account the effective condensate dimensionality. Considering ensembles of initial conditions with given values of the two conserved quantities, norm and Hamiltonian, we calculate analytically the boundary of the 'normal' Gibbsian regime corresponding to infinite temperature, and perform numerical simulations to illuminate the nature of the localization dynamics outside this regime for various cases. Furthermore, we show quantitatively how this …

Read full passage excerpt

We have studied the dynamic evolution of the collective excitations in Bose-Einstein condensates in a deep optical lattice with tunable three-body interactions. Their dynamics is governed by a high order discrete nonlinear Schrodinger equation (DNLSE). The dynamical phase diagram of the system is obtained using the variational method. The dynamical evolution shows very interesting features. The discrete breather phase totally disappears in the regime where the three-body interaction completely dominates over the two-body interaction. The soliton phase in this particular regime exists only when the soliton line approaches the critical line in the phase diagram. When weak two-body interactions are reintroduced into this regime, the discrete breather solutions reappear, but occupies a very small domain in the phase space. Likewise, in this regime, the soliton as well as the discrete breather phases completely disappear if the signs of the two-and three-body interactions are opposite. We h …

Earlier card-use comparison

The earlier diagnostic compared only cases with reported card use and text on both sides; its scope differs from the overall AI review above.

This case does not have both with-card continuation text and a model-reported use record. It remains among all 280 tests but does not enter the reported-use comparison.
