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…

Spin bath interactions effects on the geometric phase
Paula I. Villar
We calculate the geometric phase of a spin-1/2 particle coupled to an external environment comprising N spin-1/2 particle in the framework of open quantum systems. We analyze the d…
