Stokes drift is a classical fluid effect in which traveling waves transfer momentum to tracers of the fluid, resulting nonzero velocity direction incoming wave; this driving mechanism allowing particles, i.e., impurities, be transported by flow. In (viscous) happens usually due presence viscous drag forces; because eventual absence viscosity quantum fluids, impurities are driven inertial effect...

The finite-time operation of a quantum heat engine that uses a single particle as a working medium generally increases the output power at the expense of inducing friction that lowers the cycle efficiency. We propose to scale up a quantum heat engine utilizing a many-particle working medium in combination with the use of shortcuts to adiabaticity to boost the nonadiabatic performance by elimina...

The various quantum Hall effects are among the most remarkable many-body phenomena discovered in the second half of the twentieth century. 2, 3, 4 The fractional effect has yielded fractional charge, spin and statistics, as well as unprecedented order parameters. There are beautiful connections with a variety of different topological and conformal field theories of interest in nuclear and high ...

in this paper, we investigate variation of the wavelength, intensity and polarization of the self-assembled inas/gaas quantum dots emission by microphotoluminescence spectroscopy at the liquid helium temperature. the microcavity wafer sample is grown by molecular beam epitaxy (mbe) and chemically etched into the micropillar structure (with elliptical cross section - long and short axis 2µm×1.5µ...

It is a general belief that the existence of an initial singularity can be remove through the employment of a quantum theory of gravity. However, there is no consistent theory of gravity until now, and in this sense the problem of the initial singularity remains of actuality. It is well known that is possible to construct a quantum model for the universe as a whole, through the Wheeler-DeWitt (...

Nonlinear solitary structures of electron plasma waves have been investigated by using nonlinear quantum fluid equations for electrons with an arbitrary temperature. It is shown that the electron degeneracy parameter has significant effects on the linear and nonlinear properties of electron plasma waves. Depending on its value both compressive and rarefactive solitons can be excited in the mode...
