Geometric foundations of thermodynamics in the quantum regime
Ãlvaro Tejero, MartÃn de la Rosa
In this work, we present a geometrical formulation of quantum thermodynamics based on contact geometry and principal fiber bundles. The quantum thermodynamic state space is modeled…

Squeezing light to get nonclassical work in quantum engines
A. Tejero, D. Manzano, P. I. Hurtado
Light can be squeezed by reducing the quantum uncertainty of the electric field for some phases. We show how to use this purely quantum effect to extract net mechanical work from r…

Asymmetries of thermal processes in open quantum systems
Ãlvaro Tejero, Rafael Sánchez, Laiachi El Kaoutit +2
An intriguing phenomenon in non-equilibrium quantum thermodynamics is the asymmetry of thermal processes. Relaxation to thermal equilibrium is the most important dissipative proces…
