Geometric aspects of mixed quantum states inside the Bloch sphere

Paul M. Alsing, Carlo Cafaro, Domenico Felice +1

When studying the geometry of quantum states, it is acknowledged that mixed states can be distinguished by infinitely many metrics. Unfortunately, this freedom causes metric-depend…

Particle production from non-minimal coupling in a symmetry breaking potential transporting vacuum energy

Alessio Belfiglio, Youri Carloni, Orlando Luongo

We propose an inflationary scenario where the inflaton field is non-minimally coupled to spacetime curvature and inflation is driven by a vacuum energy symmetry breaking potential…

Entanglement area law violation from field-curvature coupling

Alessio Belfiglio, Orlando Luongo, Stefano Mancini

We investigate the entanglement entropy of a massive scalar field nonminimally coupled to spacetime curvature, assuming a static, spherically symmetric background. We discretize th…

Entanglement entropy for spherically symmetric regular black holes

Orlando Luongo, Stefano Mancini, Paolo Pierosara

The Bardeen and Hayward spacetimes are here considered as standard configurations of spherically symmetric regular black holes. Assuming the thermodynamics of such objects to be an…

Comparing metrics for mixed quantum states: Sjoqvist and Bures

Paul M. Alsing, Carlo Cafaro, Orlando Luongo +3

It is known that there are infinitely many distinguishability metrics for mixed quantum states. This freedom, in turn, leads to metric-dependent interpretations of physically meani…
