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…

Probing quantum geometric capacitance via photonic spin Hall effect
Yahir Fernández-Méndez, Ramón Carrillo-Bastos, Jesús A. Maytorena
The non-dissipative quasistatic longitudinal optical response of insulators is characterized by an intrinsic geometric capacitance, determined by the ratio of the quantum metric to…
