Characteristic determinant approach to the spectrum of one-dimensional -symmetric systems
Vladimir Gasparian, Peng Guo, Antonio Pérez Garrido +1
We obtain a closed form expression for the energy spectrum of -symmetric superlattice systems with complex potentials of periodic sets of two -potentials…
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…
Tunneling time in coupled-channel systems
Peng Guo, Vladimir Gasparian, Antonio Pérez-Garrido +1
In present work, we present a couple-channel formalism for the description of tunneling time of a quantum particle through a composite compound with multiple energy levels or a com…
Toward extracting the scattering phase shift from integrated correlation functions II: a relativistic lattice field theory model
Peng Guo
In present work, a relativistic relation that connects the difference of interacting and non-interacting integrated two-particle correlation functions in finite volume to infinite…
Tunneling time and Faraday/Kerr effects in -symmetric systems
Vladimir Gasparian, Peng Guo, Antonio Pérez-Garrido +1
We review the generalization of tunneling time and anomalous behaviour of Faraday and Kerr rotation angles in parity and time ()-symmetric systems. Similari…
Charged particles interaction in both a finite volume and a uniform magnetic field
Peng Guo, Vladimir Gasparian
A formalism for describing charged particles interaction in both a finite volume and a uniform magnetic field is presented. In the case of short-range interaction between charged p…
