Relativistic model of spontaneous wave-function localization induced by nonHermitian colored noise
Pei Wang
We develop a quantum field theory based on random nonHermitian actions, which upon quantization lead to stochastic nonlinear Schrödinger dynamics for the state vector. In this fra…

Random non-Hermitian Hamiltonian framework for symmetry breaking dynamics
Pei Wang
We propose random non-Hermitian Hamiltonians to model the generic stochastic nonlinear dynamics of a quantum state in Hilbert space. Our approach features an underlying linearity i…

Random non-Hermitian action theory for stochastic quantum dynamics: from canonical to path integral quantization
Pei Wang
We develop a theory of random non-Hermitian action that, after quantization, describes the stochastic nonlinear dynamics of quantum states in Hilbert space. Focusing on fermionic f…
