Thermal and dissipative effects on the heating transition in a driven critical system
Kenny Choo, Bastien Lapierre, Clemens Kuhlenkamp +3
We study the dissipative dynamics of a periodically driven inhomogeneous critical lattice model in one dimension. The closed system dynamics starting from pure initial states is we…
Neural Network Evolution Strategy for Solving Quantum Sign Structures
Ao Chen, Kenny Choo, Nikita Astrakhantsev +1
Feed-forward neural networks are a novel class of variational wave functions for correlated many-body quantum systems. Here, we propose a specific neural network ansatz suitable fo…
Hamiltonian reconstruction as metric for variational studies
Kevin Zhang, Samuel Lederer, Kenny Choo +3
Variational approaches are among the most powerful modern techniques to approximately solve quantum many-body problems. These encompass both variational states based on tensor or n…
Broken-Symmetry Ground States of the Heisenberg model on the Pyrochlore Lattice
Nikita Astrakhantsev, Tom Westerhout, Apoorv Tiwari +5
The spin-1/2 Heisenberg model on the pyrochlore lattice is an iconic frustrated three-dimensional spin system with a rich phase diagram. Besides hosting several ordered phases, the…
Construction of low-energy symmetric Hamiltonians and Hubbard parameters for twisted multilayer systems using ab-initio input
Arkadiy Davydov, Kenny Choo, Mark H. Fischer +1
A computationally efficient workflow for obtaining the low-energy symmetric tight-binding Hamiltonians for twisted multilayer systems is presented in this work. We apply this schem…
The fine structure of heating in a quasiperiodically driven critical quantum system
Bastien Lapierre, Kenny Choo, Apoorv Tiwari +3
We study the heating dynamics of a generic one dimensional critical system when driven quasiperiodically. Specifically, we consider a Fibonacci drive sequence comprising the Hamilt…
Emergent Black Hole Dynamics in Critical Floquet Systems
Bastien Lapierre, Kenny Choo, Clément Tauber +3
While driven interacting quantum matter is generically subject to heating and scrambling, certain classes of systems evade this paradigm. We study such an exceptional class in peri…
Study of the Two-Dimensional Frustrated J1-J2 Model with Neural Network Quantum States
Kenny Choo, Titus Neupert, Giuseppe Carleo
The use of artificial neural networks to represent quantum wave-functions has recently attracted interest as a way to solve complex many-body problems. The potential of these varia…
Symmetries and many-body excited states with neural-network quantum states
Kenny Choo, Giuseppe Carleo, Nicolas Regnault +1
Artificial neural networks have been recently introduced as a general ansatz to compactly represent many- body wave functions. In conjunction with Variational Monte Carlo, this ans…
