We study the Bose polaron problem in a nonequilibrium setting, by considering an impurity embedded quantum fluid of light realized exciton-polaritons microcavity, subject to coherent drive and dissipation on account pump cavity losses. obtain effective mass, drag force acting impurity, determine trajectories at semiclassical level. find different dynamical regimes, originating from unique featu...

In this paper, we deal with fluid motion in terms of quantum mechanics. Mechanism accounting for the appearance of quantum behavior is discussed. Consider a ideal fluid which is composed of discrete identical particles, its mass and charge are m and q respectively, it is convenient to consider the fluid to be a flow characterized by a 4-vector velocity field u(x1, x2, x3, x4 = ict) in a Cartesi...

In this note we demonstrate that vortices in a non-relativistic Chern-Simons theory form a quantum Hall fluid. We show that the vortex dynamics is controlled by the matrix mechanics previously proposed by Polychronakos as a description of the quantum Hall droplet. As the number of vortices becomes large, they fill the plane and a hydrodynamic treatment becomes possible, resulting in the non-com...

We study the classical and quantum models of a Friedmann-Robertson-Walker (FRW) cosmology coupled to a perfect fluid in the context of f(R) gravity. We use the Schutz’ variational formalism for the perfect fluid and show that it leads to a time parameter for the corresponding dynamical system. This formalism gives rise to a Schrödinger-Wheeler-DeWitt (SWD) equation for the quantum cosmology of ...

We revisit a model for gapped fractonic order in (2+1) dimensions (a symmetric-traceless tensor gauge theory with conservation of dipole and trace-quadrupole moments described \cite{Prem:2017kxc}) compute its ground-state entanglement entropy on $\mathbb R^2$. Along the way, we quantize open subsets R^2$ which gives rise to gapless edge excitations that are Lifshitz-type scalar theories. additi...

In a certain sense a perfect fluid is a generalization of a point particle. This leads to the question as to what is the corresponding generalization for extended objects. The lagrangian formulation of a perfect fluid is much generalized and this has as a particular example a fluid which is a classical generalization of a membrane, however there is as yet no indication of any relationship betwe...

the entanglement between a ?-type three-level atom and its spontaneous emission fields is investigated. the effect of spontaneously generated coherence (sgc) on entanglement between the atom and its spontaneous emission fields is then discussed. we find that in the presence of sgc the entanglement between the atom and its spontaneous emission fields is completely phase dependent, while in absen...
