Emergent conformal symmetry in nonunitary random dynamics of free fermions
Emergent conformal symmetry in nonunitary random dynamics of free fermions
We present random quantum circuit models for non-unitary quantum dynamics of free fermions in one spatial dimension. Numerical simulations reveal that the dynamics tends towards steady states with logarithmic violations of the entanglement area law and power law correlation functions. Moreover, starting with a short-range entangled many-body state, the dynamical …
