DOI: 10.1007/s10773-017-3321-y
Abstract: We investigate quantum entanglement in two mutually non-interacting and spatially non-overlapping Bose-Einstein condensates in two harmonic potentials with one-body losses. One-body losses play an important role in the dynamical process of generating quantum entanglement. The… read more here.

DOI: 10.1007/s11019-020-09949-0
Abstract: In current phenomenology of medicine, health is often understood as a state of transparency in which our body refrains from being an object of explicit attention. In this paper, I argue that such an understanding… read more here.

DOI: 10.1103/physreva.95.051602
Abstract: The one-body density matrix (OBDM) of a strongly interacting spinor quantum gas in one dimension can be written as a summation of products of spatial and spin parts. We find that there is a remarkable… read more here.

DOI: 10.1103/physrevc.96.054312
Abstract: In the earlier unitary-model-operator approach (UMOA), one-body correlations have been taken into account approximately by the diagonalization of unitary-transformed Hamiltonians in the $0\text{p}0\text{h}$ and $1\text{p}1\text{h}$ space. With this prescription, the dependence of the harmonic-oscillator energy… read more here.

DOI: 10.1103/physrevd.104.084058
Abstract: The inference of binary neutron star properties from gravitational-wave observations requires the generation of millions of waveforms, each one spanning about three order of magnitudes in frequency range. Thus, waveform models must be efficiently generated… read more here.

DOI: 10.1103/physrevd.105.044035
Abstract: We construct an inspiral-merger-ringdown eccentric gravitational-wave (GW) model for binary black holes with non-precessing spins within the effective-one-body formalism. This waveform model, SEOBNRv4EHM, extends the accurate quasi-circular SEOBNRv4HM model to eccentric binaries by including recently… read more here.

DOI: 10.1103/physrevd.107.084018
Abstract: We complete the nonlocal-in-time effective-one-body (EOB) formalism of conservative dynamics for massless Scalar-Tensor (ST) theories at third post-Newtonian (PN) order. The nonlocal-in-time EOB Hamiltonian is obtained by mapping the order-reduced Hamiltonian corresponding to the nonlocal-in-time… read more here.
