Universal Suppression of Dissipation across Conformal Interface in Open Quantum Critical Systems
Ruhanshi Barad, Tian Wu, Qicheng Tang +1
Conformal interfaces provide an important setting for studying universal transmission phenomena in one-dimensional quantum critical systems. While energy and information transmissi…
Exact operator dynamics in Lindbladian Wess-Zumino-Witten conformal field theories
Qicheng Tang, Ruhanshi Barad, Xueda Wen
Understanding the time evolution of physical observables in open quantum many-body systems coupled to external environments is a natural and difficult problem, and exact results ar…
Dissipation meets conformal interface in open quantum systems: How the relaxation rate is suppressed
Ruhanshi Barad, Qicheng Tang, Xueda Wen
Conformal interfaces play an important role in quantum critical systems. In closed systems, the transmission properties of conformal interfaces are typically characterized by two q…
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…
