Starting from the observation that the reduced state of a system strongly coupled to a bath is, in general, an athermal state, we introduce and study a cyclic battery-charger quantum device that is in thermal equilibrium, ...

We study nonequilibrium quantum phase transitions in the XY spin 1/2 chain using the C* algebra. We show that the well-known quantum phase transition at a magnetic field of h = 1 also persists in the nonequilibrium setting ...

We compare two different notions of dynamical phase transitions in closed quantum systems. The first is identified through the time-averaged value of the equilibrium-order parameter, whereas the second corresponds to ...

We report on an emergent dynamical phase of a strongly-correlated light-matter system, which is governed by dimerization processes due to short-range and long-range two-body interactions. The dynamical phase is characterized ...

In this paper, we discuss a novel method based on a quantum-information-tool suitable to identify and characterize quantum-phases and phase transitions in a broad set of lattice models relevant in condensed-matter systems. ...

In this work we study a polariton-exciton system confined in photonic crystal nanocavity with embedded quantum dot. Using a separable state of the type BCS, for the matter subsystem, product by a coherent state, for the ...

Se estudian las correlaciones cuánticas de dos qubits en una microcavidad con disipación y un solo modo cuantificado del campo electromagnético interactuado con ella. Para estudiar nuestro sistema físico, se utiliza el ...

Surface plasmon polaritons (SPPs) are coherent electromagnetic surface waves trapped on an insulator-conductor interface. The SPPs decay exponentially along the propagation due to conductor losses, restricting the SPPs ...

The uses of the sulfur-gold bond in the design of new molecular clusters have gained increasing attention in recent years. Their size and shape are diverse providing a wide variety of optical and electronic properties. ...
