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…
