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…
