Kibble-Zurek Mechanism and Current-Phase Relation in a Holographic Josephson Junction
Zhi-Hong Li, Huai-Fan Li, Hai-Qing Zhang
We present a comprehensive study of the current-phase relation of the Josephson junction in a holographic superfluid ring, realized from the stochastic and non-equilibrium dynamics…
Measuring Renyi Entropy in Neural Network Quantum States
Han-Qing Shi, Hai-Qing Zhang
We compute the Renyi entropy in a one-dimensional transverse-field quantum Ising model by employing a swapping operator acting on the states which are prepared from the neural netw…
Holographic Timelike Entanglement Entropy from Rindler Method
Peng-Zhang He, Hai-Qing Zhang
For a Lorentzian invariant theory, the entanglement entropy should be a function of the domain of dependence of the subregion under consideration. More precisely, it should be a fu…
Revisit the entanglement entropy with gravitational anomaly
Peng-Zhang He, Hai-Qing Zhang
In this paper we study the entanglement entropy in the CFT, whose gravity dual is AdS spacetime with a Chern-Simons term. Using the generalized Rindler method, we obtain th…
From black hole to one-dimensional chain: parity symmetry breaking and kink formation
Zhi-Hong Li, Han-Qing Shi, Hai-Qing Zhang
AdS/CFT correspondence is a "first-principle" tool to study the strongly coupled many-body systems. While it has been extensively applied to investigate the continuous symmetry bre…
Learning topological defects formation with neural networks in a quantum phase transition
Han-Qing Shi, Hai-Qing Zhang
Neural networks possess formidable representational power, rendering them invaluable in solving complex quantum many-body systems. While they excel at analyzing static solutions, n…
