Characteristic determinant approach to the spectrum of one-dimensional $P T$ -symmetric systems

Vladimir Gasparian, Peng Guo, Antonio PÃ©rez Garrido +1

We obtain a closed form expression for the energy spectrum of $P T$ -symmetric superlattice systems with complex potentials of periodic sets of two $I^´$ -potential…

Toward extracting scattering phase shift from integrated correlation functions III: coupled-channels

Peng Guo, Frank X. Lee

The formalism developed in Refs.\cite{Guo:2023ecc,Guo:2024zal} that connects integrated correlation function of a trapped two-particle system to infinite volume scattering phase sh…
