Quantum Channel-Induced Geometry of the Uhlmann Phase in Qubit Systems
F. Nieto-Guadarrama, F. Rojas, J. Villavicencio +1
We show that a cyclically controlled non-coherence-generating channel supplies a two-parameter family of closed Bloch trajectories, absent in the single-parameter (temperature) cyc…

Thermal Uhlmann phase in a locally driven two-spin system
J. Villavicencio, E. Cota, F. Rojas +3
We study the geometric Uhlmann phase of mixed states at finite temperature in a system of two coupled spin- particles driven by a magnetic field applied to one of the sp…

Zitterbewegung and Klein-tunneling phenomena for transient quantum waves
Fernando Nieto-Guadarrama, Jorge Villavicencio
We explore the dynamics of relativistic quantum waves in a potential step by using an exact solution to the Klein-Gordon equation with a point source initial condition. We show tha…
