Emergence of the Scrooge Ensemble in the Sachdev-Ye-Kitaev Model
Zeyu Liu, Pengfei Zhang
The probabilistic nature of quantum measurement provides a direct window into the structure and complexity of many-body wave functions. When only part of a system is measured, the…
The Three-Body Limit Cycle: Universal Form for General Regulators
Langxuan Chen, Feng Wu, Xincheng Lin +3
The Efimov effect, a remarkable realization of discrete scale invariance, emerges in the three-body problem with short-range interactions and is understood as a renormalization gro…
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…
Exact Renormalization Relation and Binding Energies for Three Identical Bosons
Langxuan Chen, Pengfei Zhang
In the low-energy limit, non-relativistic particles with short-range interactions exhibit universal behavior that is largely independent of microscopic details. This universality i…
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…
Scrambling Enabled Entropy Accumulation in Open Quantum Systems
Yuke Zhang, Zeyu Liu, Shuo Zhang +2
In closed quantum many-body systems, initially localized information spreads throughout the system and becomes highly complex. This phenomenon, known as information scrambling, is…
