XIX<vPHHQP<XX

Welcome to the website supporting the virtual seminar series on Pseudo-Hermitian Hamiltonians in Quantum Physics.

This virtual seminar series is part of the regular real life seminar series on Pseudo-Hermitian Hamiltonians in Quantum Physics that was initiated by Miloslav Znojil in 2003. It is intended to bridge the gap, caused by the COVID-19 pandemic, between the real life XIXth meeting and the upcoming XXth meeting in Santa Fe in 2021. For past events see the PHHQP website. The subject matter of this series is the study of physical aspects of non-Hermitian systems from a theoretical and experimental point of view. Of special interest are systems that possess a PT-symmetry (a simultaneous reflection in space and time).

Time dependent pseudo-bosonic coherent states

Abstract: We discuss the extension of non-Hermitian integrals of motion method to cases where the quantum systems are described by time-dependent non-Hermitian Hamiltonians. We introduce a time dependent metric in order to construct time-dependent non-Hermitian pseudo-bosonic coherent states as eigenstates of pseudo-Hermitian boson annihilation operators that are time-dependent non-Hermitian linear invariants. As illustration, we study the time-dependent non-Hermitian Swanson Hamiltonian.
