Geometric phase with nonunitary evolution in presence of a quantum critical bath
F. M. Cucchietti, J. -F. Zhang, F. C. Lombardo +2
Geometric phases, arising from cyclic evolutions in a curved parameter space, appear in a wealth of physical settings. Recently, and largely motivated by the need of an experimenta…
Casimir energy between media-separated cylinders: the scalar case
F. C. Lombardo, F. D. Mazzitelli, P. I. Villar +1
We derive exact expressions for the Casimir scalar interaction energy between media-separated eccentric dielectric cylinders and for the media-separated cylinder-plane geometry usi…
Using boundary methods to compute the Casimir energy
F. C. Lombardo, F. D. Mazzitelli, P. I. Villar
We discuss new approaches to compute numerically the Casimir interaction energy for waveguides of arbitrary section, based on the boundary methods traditionally used to compute eig…
Environmentally-induced effects on a bipartite two-level system: geometric phase and entanglement properties
Fernando C. Lombardo, Paula I. Villar
We calculate the geometric phase of a bipartite two-level system coupled to an external environment. We analyze the reduced density matrix for an arbitrary initial state of the com…
