The purpose of this paper is to articulate a coherent and easy-to-understand way of doing
quantum mechanics in any finite-dimensional Liouville space, based on the use of a …

We consider a general model of unitary parameter estimation in the presence of Markovian
noise, where the parameter to be estimated is associated with the Hamiltonian part of the …

We investigate heat engines whose working substance is made of two coupled qubits
performing a generalized Otto cycle by varying their applied magnetic field or their …

We study the nonequilibrium dynamics of axionlike particles (ALP) coupled to Standard
Model degrees of freedom in thermal equilibrium. The quantum master equation (QME) for …

We study the effect of quantum decoherence on the inflationary cosmological perturbations.
This process might imprint specific observational signatures revealing the quantum nature of …

In quantum information theory, quantum discord has been proposed as a tool to characterise
the presence of" quantum correlations" between the subparts of a given system. Whether a …

Since inflationary perturbations must generically couple to all degrees of freedom present in
the early Universe, it is more realistic to view these fluctuations as an open quantum system …

We investigate the dissipative dynamics yielded by the Lindblad equation within the
coexistence region around a first-order phase transition. In particular, we consider an exactly …

We study the back-reaction of quantum systems onto classical ones. Taking the starting
point that semi-classical physics should be described at all times by a point in classical …

Fenna-Mathews-Olson complexes participate in the photosynthetic process of Sulfur Green
Bacteria. These biological subsystems exhibit quantum features which possibly are …
