Z2 topological order and first-order quantum phase transitions in systems with combinatorial gauge symmetry
Kai-Hsin Wu, Zhi-Cheng Yang, Dmitry Green +2
We study a generalization of the two-dimensional transverse-field Ising model, combining both ferromagnetic and antiferromagnetic two-body interactions, that hosts exact global and…
Theory for the negative longitudinal magnetoresistance in the quantum limit of Kramers Weyl semimetals
Bo Wan, Frank Schindler, Ke Wang +4
Negative magnetoresistance is rare in non-magnetic materials. Recently, a negative magnetoresistance has been observed in the quantum limit of -AgSe, where only one band of…
Entanglement Renyi negativity across a finite temperature transition: a Monte Carlo study
Kai-Hsin Wu, Tsung-Cheng Lu, Chia-Min Chung +2
Quantum entanglement is fragile to thermal fluctuations, which raises the question whether finite temperature phase transitions support long-range entanglement similar to their zer…
Generation of ice states through deep reinforcement learning
Kai-Wen Zhao, Wen-Han Kao, Kai-Hsin Wu +1
We present a deep reinforcement learning framework where a machine agent is trained to search for a policy to generate a ground state for the square ice model by exploring the phys…
Tunneling-induced restoration of classical degeneracy in quantum kagome ice
Kai-Hsin Wu, Yi-Ping Huang, Ying-Jer Kao
Quantum effect is expected to dictate the behaviour of physical systems at low temperature. For quantum magnets with geometrical frustration, quantum fluctuation usually lifts the…
Dynamic scaling in the 2D Ising spin glass with Gaussian couplings
Na Xu, Kai-Hsin Wu, Shanon J. Rubin +2
We carry out simulated annealing and employ a generalized Kibble-Zurek scaling hypothesis to study the 2D Ising spin glass with normal-distributed couplings. The system has an equi…
