Shallow Unitary Circuits for Kramers-Wannier Dualities
Yanting Cheng, Shang Liu
The quantum Kramers-Wannier (KW) duality is a fundamental transformation mapping short-range entangled (SRE) states to long-range entangled (LRE) states. While spatially local unit…
Unleashing Emergent Fermions with Rydberg Atom Simulators
Hanteng Wang, Xingyu Li, Shang Liu +2
Rydberg atom simulators, in both analog and digital modes, have attracted significant recent interest due to their versatile geometric reconfigurability. In this work, leveraging t…
Lattice Defects in Rydberg Atom Arrays
Hanteng Wang, Chengshu Li, Xingyu Li +2
Rydberg atom arrays have become a key platform for studying quantum many-body systems. In these setups, defects arise naturally due to various imperfections and can significantly m…
Deep Boundary Perturbations at a Quantum Critical Point
Shang Liu
In this work, we explore an unconventional class of problems in the study of (quantum) critical phenomena, termed ''deep boundary criticality''. Traditionally, critical systems are…
