\section{Quantum Optics of Quantum Gases}
|
||||
|
||||
Having introduced and described the behaviour of ultracold bosons
|
||||
trapped and manipulated using classical light, it is time to extend
|
||||
the discussion to quantized optical fields. We will first derive a
|
||||
general Hamiltonian that describes the coupling of atoms with
|
||||
far-detuned optical beams \cite{mekhov2012}. This will serve as the
|
||||
basis from which we explore the system in different parameter regimes,
|
||||
such as nondestructive measurement in free space or quantum
|
||||
measurement backaction in a cavity.
|
||||
|
||||
We consider $N$ two-level atoms in an optical lattice with $M$
|
||||
sites. For simplicity we will restrict our attention to spinless
|
||||
bosons, although it is straightforward to generalise to fermions,
|
||||
which yields its own set of interesting quantum phenomena
|
||||
\cite{atoms2015, mazzucchi2016, mazzucchi2016af}, and other spin
|
||||
particles. The theory can be also be generalised to continuous
|
||||
systems, but the restriction to optical lattices is convenient for a
|
||||
variety of reasons. Firstly, it allows us to precisely describe a
|
||||
many-body atomic state over a broad range of parameter values due to
|
||||
the inherent tunability of such lattices. Furthermore, this model is
|
||||
capable of describing a range of different experimental setups ranging
|
||||
from a small number of sites with a large filling factor (e.g.~BECs
|
||||
trapped in a double-well potential) to a an extended multi-site
|
||||
lattice with a low filling factor (e.g.~a system with one atom per
|
||||
site will exhibit the Mott insulator to superfluid quantum phase
|
||||
transition). \mynote{extra fermion citations, Piazza?}
