Adiabatic-impulse approximation in the non-Hermitian Landau-Zener model
Adiabatic-impulse approximation in the non-Hermitian Landau-Zener model
In the non-Hermitian Landau-Zener models, we investigate the dynamical transition both in parity-time symmetric and symmetry-broken regimes. Taking into account the complex nature of the energy of the non-Hermitian systems, the absolute value of the gap was used to determine the relaxation rate of the system. To show the dynamics …
