Simulating fermionic fractional Chern insulators with infinite projected entangled-pair states
Hao Chen, Titus Neupert, Juraj Hasik
Infinite projected entangled-pair states (iPEPS) provide a powerful variational framework for two-dimensional quantum matter and have been widely used to capture bosonic topologica…
CMT-Benchmark: A Benchmark for Condensed Matter Theory Built by Expert Researchers
Haining Pan, James V. Roggeveen, Erez Berg +16
Large language models (LLMs) have shown remarkable progress in coding and math problem-solving, but evaluation on advanced research-level problems in hard sciences remains scarce.…
Simulating Spin Dynamics of Supersolid States in a Quantum Ising Magnet
Yi Xu, Juraj Hasik, Boris Ponsioen +1
Motivated by a recent experimental study on the quantum Ising magnet that presented spectroscopic evidence of zero-field supersolidity (Chen e…
How quantum fluctuations freeze a classical liquid and then melt it into a topological one
Hao Chen, Dan Mao, Andrea Kouta Dagnino +5
Topologically ordered quantum liquids are highly sought-after quantum phases of matter, and recently, fractional Chern insulators (FCIs) joined the few experimental realizations of…
Exploiting the Hermitian symmetry in tensor network algorithms
Oscar van Alphen, Stijn V. Kleijweg, Juraj Hasik +1
Exploiting symmetries in tensor network algorithms plays a key role for reducing the computational and memory costs. Here we explain how to incorporate the Hermitian symmetry in do…
