Emergent Non-Biorthogonal Born Rule at Dynamical Quantum Phase Transitions

Non-Hermitian dynamics possesses distinct left and right eigenstates, but their normalization freedom obscures a direct probabilistic interpretation. Starting from a globally Hermitian system governed by the standard Born rule, we generalize dynamical quantum phase transitions (DQPTs) from a reference state to a physic...

Non-Hermitian Quantum Mechanics I: Instantaneous Self-Energy

Starting from the unitary evolution of a closed quantum system, we rigorously demonstrate that the projection of the global wavefunction onto an arbitrary local subsystem is governed by an exact, time-dependent non-Hermitian Schr\"odinger equation. Crucially, the derivation does not rely on conventional approximations...
