Energy-level crossings and number-parity effects in a bosonic tunneling model

22 Jan 2018 Agboola Davids Isaac Phillip S. Links Jon

An exactly solved bosonic tunneling model is studied along a line of the coupling parameter space, which includes a quantum phase boundary line. The entire energy spectrum is computed analytically, and found to exhibit multiple energy level crossings in a region of the coupling parameter space... (read more)
