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…

A critical state under weak measurement is not critical
Qicheng Tang, Xueda Wen
Critical systems host nontrivial entanglement structure that is generally sensitive to additional couplings. In the present work, we study the effect of weak measurements on the en…
