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…
Exactly solvable non-unitary conformal interfaces in unitary CFTs
Qicheng Tang, Zixia Wei, Xueda Wen
We construct directly on the lattice a class of non-unitary interfaces that are both exactly conformal and exactly solvable, and establish their corresponding boundary and interfac…
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…
Detecting Higher Berry Phase via Boundary Scattering
Chih-Yu Lo, Xueda Wen
Higher Berry phase has recently been proposed to study the topology of the space of gapped many-body quantum systems. In this work, we develop a boundary-scattering approach to det…
