Universal Relations in Long-range Quantum Spin Chains
Ning Sun, Lei Feng, Pengfei Zhang
Understanding the emergence of novel collective behaviors in strongly interacting systems lies at the heart of quantum many-body physics. Valuable insight comes from examining how…
Hybrid Brownian SYK-Hubbard Model: from Spectral Function to Quantum Chaos
Ning Sun, Peng Zhang, Pengfei Zhang
Understanding the emergence of complex correlations in strongly interacting systems remains a fundamental challenge in quantum many-body physics. One fruitful approach is to develo…
Stabilizer Rényi Entropy and its Transition in the Coupled Sachdev-Ye-Kitaev Model
Pengfei Zhang, Shuyan Zhou, Ning Sun
Quantum entanglement and quantum magic are two distinct fundamental resources that enable quantum systems to exhibit complex phenomena beyond the capabilities of classical computer…
Universal Bound States in Long-range Spin Chains with an Impurity
Ning Sun, Lei Feng, Pengfei Zhang
Understanding how quasi-particles interact with impurities is crucial for unveiling novel properties of quantum many-body systems. A prominent example is the enhanced scattering be…
Efimov Effect in Long-range Quantum Spin Chains
Ning Sun, Lei Feng, Pengfei Zhang
When two non-relativistic particles interact resonantly in three dimensions, an infinite tower of three-body bound states emerges, exhibiting a discrete scale invariance. This univ…
Scheme to Detect the Strong-to-weak Symmetry Breaking via Randomized Measurements
Ning Sun, Pengfei Zhang, Lei Feng
Symmetry breaking plays a central role in classifying the phases of quantum many-body systems. Recent developments have highlighted a novel symmetry-breaking pattern, in which the…
