Quantum simulation of the 2D-3D superfluid deconfinement transition with quantum degenerate 87Rb gases
Abstract/Contents
- Abstract
- Since Bose Einstein condensate (BEC) of alkali atomic gases was realized in 1995, its novel material properties have inspired tremendous research ideas and experiments. BEC is characterized by macroscopic occupation of ground state and has long range order. The coherent wave property of BEC provides a new target to implement and test knowledge gained from quantum optics. Furthermore, the application of optical lattices into condensate boosts the diversity of research. The implementation of optical lattice not only makes realization of Heisenberg interferometer via number squeezed state possible, but also provides a periodic potential to investigate condensed matter physics in atomic system. For research conducted by former members in 87Rb group, they mainly studied squeezed state and dynamics of condensates in 1D optical lattice at zero temperature. The intention of my research is meant to explore coherence property of 87Rb quantum degenerated gases at finite temperature as a function of inter-layer tunnelling probability for potential application of atomic interferometry. On my way of investigating coherence of 2D Bose gases confined in 1D optical, I observe deconfinement transition from 2D Berezinskii-Kosterlitz-Thouless superfluids to 3D anisotropic superfluids. Moreover, I also realize this system can potentially serve as a quantum simulator of layered high-Tc superconductor in 2D regime. In this thesis, I will mention how I investigate coherence of ensemble of 2D Bose gases. Later, I'll also simulate deconfinement transition based on Renormalization Group(RG) theory with our experimental parameters.
