Tripartite quantum Rabi model with trapped Rydberg ions
Thomas J. Hamlyn, Chi Zhang, Igor Lesanovsky +1
We investigate a tripartite quantum Rabi model (TQRM) wherein a bosonic mode concurrently couples to two spin- particles through a spin-spin interaction, resulting in a spin-s…
Scalable simulation of non-equilibrium quantum dynamics via classically optimised unitary circuits
Luke Causer, Felix Jung, Asimpunya Mitra +2
The advent of near-term digital quantum computers could offer us an exciting opportunity to investigate quantum many-body phenomena beyond that of classical computing. To make the…
Avalanche terahertz photon detection in a Rydberg tweezer array
Chris Nill, Albert Cabot, Arno Trautmann +2
We propose a protocol for the amplified detection of low-intensity terahertz radiation using Rydberg tweezer arrays. The protocol offers single photon sensitivity together with a l…
Spectral Signatures of Vibronic Coupling in Trapped Cold Ionic Rydberg Systems
Joseph W. P. Wilkinson, Weibin Li, Igor Lesanovsky
Atoms and ions confined with electric and optical fields form the basis of many current quantum simulation and computing platforms. When excited to high-lying Rydberg states, long-…
Coherent spin-phonon scattering in facilitated Rydberg lattices
Matteo Magoni, Chris Nill, Igor Lesanovsky
We investigate the dynamics of a spin system with facilitation constraint that can be studied using Rydberg atoms in arrays of optical tweezer traps. The elementary degrees of free…
Quench dynamics in lattices above one dimension: the free fermionic case
Molly Gibbins, Arash Jafarizadeh, Adam Gammon-Smith +1
We begin a systematic investigation of quench dynamics in higher-dimensional lattice systems considering the case of non-interacting fermions with conserved particle number. We pre…
