Bipartite entanglement of the primordial Majorana during inflation
Ai-chen Li, Han-Qing Shi, Keyun Wu
We use a primordial Majorana field as a fermionic probe of quantum correlations during inflation. Working in a torsion-free FLRW spacetime, we derive the two-component Majorana mod…
Learning the Renyi entropy of multiple disjoint intervals in transverse-field quantum Ising models with restricted Boltzmann machine
Han-Qing Shi, Hai-Qing Zhang
Renyi entropy with multiple disjoint intervals are computed from the improved swapping operations by two methods: one is from the direct diagonalization of the Hamiltonian and the…
A universal approach to Renyi entropy of multiple disjoint intervals
Han-Qing Shi, Hai-Qing Zhang
We develop a general theory for computing the Renyi entropy with general multiple disjoint intervals from the swapping operations. Our theory is proposed based on the fact that we…
HiMA: Hierarchical Quantum Microarchitecture for Qubit-Scaling and Quantum Process-Level Parallelism
Qi Zhou, Zi-Hao Mei, Han-Qing Shi +10
Quantum computing holds immense potential for addressing a myriad of intricate challenges, which is significantly amplified when scaled to thousands of qubits. However, a major cha…
Universal Critical Holography and Domain Wall Formation
Tian-Chi Ma, Han-Qing Shi, Hai-Qing Zhang +1
Using holography, we study the universal scaling laws governing the coarsening dynamics of strongly coupled domain walls. Specifically, we studied the universal dependence of the l…
Asymmetric Symmetry Breaking: Unequal Probabilities of Vacuum Selection
Tian-Chi Ma, Han-Qing Shi, Hai-Qing Zhang
Spontaneous symmetry breaking is a fundamental notion in modern physics, ranging from high energy to condensed matter. However, the usual spontaneous symmetry breaking only conside…
Topologically Protected Metastable States in Classical Dynamics
Han-Qing Shi, Tian-Chi Ma, Hai-Qing Zhang
We propose that domain walls formed in a classical Ginzburg-Landau model can exhibit topologically stable but thermodynamically metastable states. This proposal relies on Allen-Cah…
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…
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…
Holographic topological defects in a ring: role of diverse boundary conditions
Zhi-Hong Li, Han-Qing Shi, Hai-Qing Zhang
We investigate the formation of topological defects in the course of a dynamical phase transition with different boundary conditions in a ring from AdS/CFT correspondence. Accordin…
Chaotic D1-D5 Black Hole Dynamics through Networks
Han-qing Shi, Xiao-yue Sun, Ding-fang Zeng
This work studies dynamics controlling the transition between different microstates of two charge D1-D5 black holes by network methods, in which microstates of the system are defin…
Phase Structure and QNMs of A Charged AdS Dilaton Black Hole
Ai-chen Li, Han-qing Shi, Ding-fang Zeng
We investigate the phase structure of a charged AdS dilaton black hole in the extended phase space which takes the cosmological constant, i.e. the AdS- parameter as pressures. T…
Geodesic Motions in AdS Soliton Background Space-time
Han-qing Shi, Ding-fang Zeng
We study both massive and massless particle's geodesic motion in the background of general dimensional AdS-Sol space-time. We find that the massive particles oscillate along the ra…
