Few-Magnon Universality beyond Contact Interactions in Long-Range Spin Chains
Yiran Huo, Pengfei Zhang
Quantum few-body systems exhibit a rich variety of phenomena that provide fundamental insights into universality. A paradigmatic example is the Efimov effect, in which an infinite…
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…
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…
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…
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…
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…
Strong-to-weak Symmetry Breaking and Entanglement Transitions
Langxuan Chen, Ning Sun, Pengfei Zhang
When interacting with an environment, the entanglement within quantum many-body systems is rapidly transferred to the entanglement between the system and the bath. For systems with…
Bounding the Sample Fluctuation for Pure States Certification with Local Random Measurement
Langxuan Chen, Pengfei Zhang
Remarkable breakthroughs in quantum science and technology are demanding for more efficient methods in analyzing quantum many-body states. A significant challenge in this field is…
Diagnosing Strong-to-Weak Symmetry Breaking via Wightman Correlators
Zeyu Liu, Langxuan Chen, Yuke Zhang +2
Symmetry plays a fundamental role in quantum many-body physics, and a central concept is spontaneous symmetry breaking, which imposes crucial constraints on the possible quantum ph…
