Thermal activation and macroscopic quantum phenomena in superconducting devices
… to both thermal activation over the barrier and macroscopic quantum tunneling through the barrier. The measurements were performed for a variety of device parameters, corresponding to different shapes of the potential barrier. We find strong evidence for macroscopic quantum tunneling in both one …

Some problems on macroscopic quantum phenomena and josephson junctions
… two parts. In the' first part, the theory of quantum dynamics of a general particle in fermionic heat baths is considerd. In contrast to the existing work in the literature, we employ a path. integral formalism with fermions being treated in Grassmann algebra. Working on this formalism, we are …

Effects of interactions on correlation, thermalization, and transport of exciton-polaritons
… are hybrid quasiparticles in a semiconductor quantum-well microcavity that exhibit both light-matter and matter-matter interactions. Polaritons have the effective mass inherited from the ultralight cavity photon mass, which sets polariton transport phenomena to be photon-like and allows …

Exotic Phenomena Emerging from Localized Multipolar Degrees of Freedom
… matter systems offers the opportunity for exotic macroscopic quantum phenomena. Multipolar moments, higher order generalizations of the familiar dipole, present a unique avenue for the discovery of a variety of exotic and novel phases of matter. These anisotropic charge and magnetization densities …

Novel ground states of Bose-condensed gases
… (BEC) provide a novel tool for the study of macroscopic quantum phenomena and condensed matter systems. Two of the recent frontiers, quantized vortices and ultracold molecules, are the subject of this thesis. The formation of highly-ordered vortex lattices in a Bose-condensed gas has been …
