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…
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…
Phase transitions in 3D Ising model with cluster weight by Monte Carlo method
Ziyang Wang, Le Feng, Wanzhou Zhang +1
A cluster weight Ising model is proposed by introducing an additional cluster weight in the partition function of the traditional Ising model. It is equivalent to the O() loop m…
