Abstract: The nonclassicality is the prerequisite for quantum states to be applied into quantum information, especially for quantum metrology. Here we theoretically investigate the non-classical properties of the non-Gaussian state generated by repeatedly operating a number-conserving… read more here.

DOI: 10.1142/s0217732320500224
Abstract: By the use of coherent and squeezed thermal states formalism, we analyzed the phenomena of particle creation when coherently oscillating a homogeneous scalar field (Inflaton) in semi-classical gravity. We also obtained an estimated solution for… read more here.

DOI: 10.1142/s0219749919500308
Abstract: Steering, a quantum property existing in some bipartite entangled systems, causes the local measurements on one part to change the state of the other part at any distance. In this paper, the dynamics of steering… read more here.

DOI: 10.3390/e25010128
Abstract: Irreversible entropy production (IEP) plays an important role in quantum thermodynamic processes. Here, we investigate the geometrical bounds of IEP in nonequilibrium thermodynamics by exemplifying a system coupled to a squeezed thermal bath subject to… read more here.
