Abstract
Main purpose of this thesis is to present a discussion of the effects
of artificial spin-orbit coupling and Zeeman fields in fermionic
ultra-cold atoms. Part of the work described here is inspired by
the experimental realization of artificial spin-orbit coupling (SOC) in the
fermionic isotope $^{40}$K using a Raman technique, which was done by NIST group recently. The first aspect investigated is the formation of
two-body bound states of fermions when artificial spin-orbit
coupling and artificial Zeeman fields are present. These bound-states
are analyzed for two-hyperfine-state fermions in free space and
in a harmonically confining potential. The second aspect explored
is the study of spectroscopic and thermodynamic properties of
three-hyperfine-state fermions. These properties are investigated
as a function of spin-orbit coupling and Zeeman fields for non-interacting
atoms, but when atom-atom interactions are also included, the many-body
system consisting of three-hyperfine-state fermions
can exhibit exotic superfluid phases.
