Permutation invariant multi-scale full quantum neural network wavefunction

This paper introduces a permutation-invariant, multi-scale full quantum neural network framework that accurately models the joint wavefunction of electrons, nuclei, and muons beyond the Born-Oppenheimer approximation, offering a computationally feasible solution for capturing complex quantum correlations in many-body systems.

Delocalization of the height function of the six-vertex model

This paper proves that the height function of the six-vertex model with parameters a=b=1a=b=1 and $1 \le c \le 2exhibitsdelocalizationwithlogarithmicvariance,therebycompletingthecharacterizationofthemodelsphasetransitionbycomplementingtheknownlocalizationbehaviorfor exhibits delocalization with logarithmic variance, thereby completing the characterization of the model's phase transition by complementing the known localization behavior for c > 2$.

Formal multiparameter quantum groups, deformations and specializations

This paper introduces formal multiparameter quantum universal enveloping algebras (FoMpQUEA) as a generalization of Drinfeld's quantum groups, demonstrating that they are closed under toral twists and 2-cocycle deformations, establish a bijective correspondence with multiparameter Lie bialgebras via quantization and semiclassical limits, and prove that specialization and deformation processes commute.
