Eigenstates Transition without Undergoing an Adiabatic Process
Author(s): Fatemeh Mostafavi, Luqi Yuan, and Hamidreza Ramezani
We introduce a class of non-Hermitian Hamiltonians that offers a dynamical approach to a shortcut to adiabaticity (DASA). In particular, in our proposed $2×2$ Hamiltonians, one eigenvalue is absolutely real and the other one is complex. This specific form of eigenvalues helps us to exponentially dec...
