Boundary Criticality of Complex Conformal Field Theory: A Case Study in the Non-Hermitian 5-State Potts Model
Yin Tang, Qianyu Liu, Qicheng Tang +1
Conformal fields with boundaries give rise to rich critical phenomena that can reveal information about the underlying conformality. While most existing studies focus on Hermitian…
Universal time evolution of string order parameter in quantum critical systems with boundary invertible or non-invertible symmetry breaking
Ruhanshi Barad, Qicheng Tang, Wei Zhu +1
The global symmetry, either invertible or non-invertible, has been extensively studied in two dimensional conformal field theories in recent years. When the theory is defined on a…
Quantum Monte Carlo Simulation of the 3D Ising Transition on the Fuzzy Sphere
Johannes S. Hofmann, Florian Goth, Wei Zhu +2
We present a numerical quantum Monte Carlo (QMC) method for simulating the 3D phase transition on the recently proposed fuzzy sphere [Phys. Rev. X 13, 021009 (2023)]. By introducin…
Thermal Correction to Entanglement Spectrum for Conformal Field Theories
Yin Tang, Qicheng Tang, W. Zhu
We calculate the thermal correction to the entanglement spectrum for separating a single interval of two dimensional conformal field theories. Our derivation is a direct extension…
Entanglement Hamiltonian of Many-body Dynamics in Strongly-correlated Systems
W. Zhu, Zhoushen Huang, Yin-Chen He +1
A powerful perspective in understanding non-equilibrium quantum dynamics is through the time evolution of its entanglement content. Yet apart from a few guiding principles for the…
Reconstructing Entanglement Hamiltonian via Entanglement Eigenstates
W. Zhu, Zhoushen Huang, Yin-chen He
The entanglement Hamiltonian , defined through the reduced density matrix of a subsystem , is an important concept in understanding the nature of quantum entan…
