Tunneling time in -symmetric systems
Peng Guo, Vladimir Gasparian, Esther Jódar +1
In the present work we propose a generalization of tunneling time in parity and time ()-symmetric systems. The properties of tunneling time in $\mathcal{P}\…
Friedel formula and Krein's theorem in complex potential scattering theory
Peng Guo, Vladimir Gasparian
In this work, the generalization of Friedel formula and Krein's theorem in complex potential scattering theory is presented. The consequence of various symmetry constraints on dyna…
Charged particles interaction in both a finite volume and a uniform magnetic field II: topological and analytic properties of a magnetic system
Peng Guo, Vladimir Gasparian
In present work, we discuss some topological features of charged particles interacting a uniform magnetic field in a finite volume. The edge state solutions are presented, as a sig…
Nuclear reactions in artificial traps
Peng Guo, Bingwei Long
Coupled-channel two-particle systems bound by a harmonic trap are discussed in the present paper. We derive the formula that relates the energy levels of such trapped systems to ph…
Coulomb corrections to two-particle interaction in artificial traps
Peng Guo
In present work, we discuss the effect of Coulomb interaction to the dynamics of two-particle system bound in various traps. The strategy of including Coulomb interaction into the…
Myth of scattering in finite volume
Peng Guo
In this notes, we illustrate why the infinite volume scattering amplitude is in fact dispensable when it comes to formulating few-body quantization condition in finite volume. Only…
