Designing a Multimode Cavity for a Degenerate Cavity QED Apparatus
POSTER
Abstract
Cavity QED (cQED) has found great use in both analog quantum simulation and entanglement engineering for its ability to generate strong long-range interactions between atoms. To further build on this, multimode cQED is an appealing prospect, as being able to control the number of cavity modes participating in atom-light interactions adds the ability to engineer more complex coupling than the all-to-all interactions seen in single mode cavities. Previous experiments have already used multimode cavities to induce phonon-like effects for ultracold atoms within optical lattices [1], as well as explore unique spin glass phases for ultracold bosons [2].
We will describe the design of our current optical cavity, which will serve as the core of a future multimode cQED experiment involving 6Li, and also describe our plans for the integration of this cavity into our UHV system. We will also highlight our future plans for the fermionic multimode cQED experiments this cavity will be used for. In particular, we will discuss our plans for the analog quantum simulation of holographic models such as the Sachdev-Ye-Kitaev (SYK) model, which will leverage the degeneracy of our cavity modes, a randomly disordered optical potential, and strong atom-light interactions between fermions to generate quantum chaotic dynamics and fast quantum information scrambling [3].
