Walshness: an intrinsic neural-network representability metric for quantum states
Nisarga Paul, Kehuang Chen, Jessica K. Jiang +2
Neural quantum states (NQS) have emerged as powerful representations of quantum states with rapidly expanding applications across quantum many-body physics. Yet our understanding o…
Learning the closest Slater determinant
Nisarga Paul, Haimeng Zhao, David D. Dai
Learning compact, interpretable descriptions of quantum many-body states is an important task in quantum science. We study the task of learning the Slater determinant with maximum…
Bootstrapping ground state properties of classical frustrated magnets
Nisarga Paul, Gil Refael
We introduce a method based on semidefinite programming that produces rigorous two-sided bounds on ground state energy densities and correlation functions of translation-invariant…
Resonant Zener Interferometry in van der Waals Heterostructures
Nisarga Paul, Gil Refael
We demonstrate the presence of quantum interference effects in van der Waals heterostructures subject to in-plane electric fields. The in-plane field accelerates carriers throu…
Higher-dimensional Fermiology in bulk moiré metals
Kevin P. Nuckolls, Nisarga Paul, Alan Chen +10
In the past decade, moiré materials have revolutionized how we engineer and control quantum phases of matter. Among incommensurate materials, moiré materials are aperiodic composit…
Bound on entanglement in neural quantum states
Nisarga Paul
Variational wavefunctions offer a practical route around the exponential complexity of many-body Hilbert spaces, but their expressive power is often sharply constrained. Matrix pro…
Reconstructing the Hamiltonian from the local density of states using neural networks
Nisarga Paul, Andrew Ma, Kevin P. Nuckolls
Reconstructing a quantum system's Hamiltonian from limited yet experimentally observable information is interesting both as a practical task and from a fundamental standpoint. We p…
Gyrotropic magnetic effect in metallic chiral magnets
Nisarga Paul, Takamori Park, Jung Hoon Han +1
We study the gyrotropic magnetic effect (GME), the low-frequency limit of optical gyrotropy, in metals and semimetals coupled to chiral spin textures. In these systems, the chiral…
Stability of sub-dimensional localization to electronic interactions
Nisarga Paul, Philip J. D. Crowley
Sub-dimensional localization, also known as directional localization, arises when 2d electrons are subject to a periodic potential and incommensurate magnetic field which cause the…
