DOI: 10.1007/s10773-017-3655-5
Abstract: The tripartite Negativity is adopted to quantify the degree of entanglement among three subsystems. The situation is considered that three identical two-level atoms are trapped in a single-mode optical cavity, and each atom off-resonantly interacts… read more here.

DOI: 10.1007/s10773-017-3661-7
Abstract: We investigate tripartite entanglement in an atom-cavity-optomechanical system consisting of a two-level atom coupled to a cavity with an oscillating mirror at one end. The maximally entangled state between the atom, the field and the… read more here.

DOI: 10.1007/s11128-018-1957-z
Abstract: A new and direct measure (without bipartite measures) of genuine entanglement in tripartite systems based on the volume of the negative part of the Wigner function is proposed. We analyze comparatively this quantity and the… read more here.

DOI: 10.1103/physrevlett.118.036102
Abstract: The emergence of a diverging length scale in many-body systems at a quantum phase transition implies that total entanglement has to reach its maximum there. In order to fully characterize this, one has to consider… read more here.

DOI: 10.1142/s0219749918500557
Abstract: The notion of entanglement is the most well-known nonclassical correlation in quantum mechanics, and a fundamental resource in quantum information and computation. This correlation, which is displayed by certain classes of quantum states, is of… read more here.
