Spacetime Supersymmetry in the Truncated Lattice Schwinger Model
Yanting Cheng, Shang Liu
Gauge theories in (1+1)D have attracted renewed attention partially due to their experimental realizations in quantum simulation platforms. In this work, we revisit the truncated l…
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…
Spontaneous breaking of non-invertible symmetries and duality to beyond-Landau transitions
Xie Chen, Shang Liu, Da-chuan Lu +1
Spontaneous symmetry breaking is a well-understood mechanism for generating distinct phases of matter. Recently, the notion of symmetry has been broadened to include operations wit…
Constructing Bulk Topological Orders via Layered Gauging
Shang Liu
Understanding quantum phases and phase transitions in the presence of symmetries is a central objective of quantum many-body physics. A powerful modern paradigm for investigating t…
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…
