Quantum electrodynamics in $1+1$ dimensions (Schwinger model) on an interval admits lattice discretization with a finite-dimensional Hilbert space, and is often used as testbed for quantum tensor network simulations. In this work we clarify the precise mapping between boundary conditions continuum theories. particular show that conventional Gauss law constraint commonly simulations induces stro...

Recently, molecular dynamics simulations have predicted that when carbon dioxide gas enters a nanotube, concentric layers of gaseous molecules will appear. We show in this letter how effect can be analytically by considering the potential field generated pore wall. The layer expression thus derived used to reproduce essential features particular MD study within (40, 40) nanotube and confirm, fr...
