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…
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…
Modeling few-body resonances in finite volume
Peng Guo
Under the assumption of separable interactions, we illustrate how the few-body quantization condition may be formulated in terms of phase shifts in general, which may be useful for…
Visualizing resonances in finite volume
Peng Guo, Bingwei Long
In present work, we explore and experiment an alternative approach of studying resonance properties in finite volume. By analytic continuing finite lattice size into complex pl…
Threshold expansion formula of -boson in finite volume from variational approach
Peng Guo
In present work, we show how the threshold expansion formula of identical bosons in finite volume may be derived by iterations of Faddeev-type coupled dynamical equations. The…
Multi- systems in finite volume
Peng Guo, Bingwei Long
We present a formalism to describe two- and three- dynamics in finite volume, the formalism is based on combination of a variational approach and the Faddeev method. Both…
