Title: Emulating Solid-State Physics with a Hybrid System of Ultracold
Ions and Atoms
Abstract:
A hybrid system composed of a crystal of trapped ions coupled to a cloud of
ultracold fermions is proposed and discussed as an analog quantum
simulator. The ions form a periodic lattice and induce a band structure in
the atoms. This system combines the advantages of high fidelity operations
and detection offered by trapped ion systems with ultracold atomic systems.
It also features close analogies to natural solid-state systems, as the
atomic degrees of freedom couple to phonons of the ion lattice, thereby
emulating a solid-state system. Starting from the microscopic many-body
Hamiltonian,the low energy Hamiltonian, including the atomic band structure
is derived. The atom-phonon coupling is found to be highly tunable,
allowing for the realization of strongly correlated atom-phonon systems.
Possible experimental implementations such as a Peierls-like transition
into a period-doubled dimerized state are presented.
