Many-body spin dynamics with rydberg-dressed atoms
Abstract/Contents
- Abstract
- A fundamental challenge of quantum science is to introduce controllable interactions in well isolated quantum systems. One approach is to excite neutral atoms to Rydberg states, thereby creating optically controlled long-range interactions. In order to take advantage of both the long-range interactions of the Rydberg states and the long spin-coherence times of ground-state atoms, we off-resonantly couple a cold dilute gas of cesium atoms to Rydberg states, using the technique of Rydberg dressing. In this thesis, I present the first experimental realization of the transverse-field Ising model with Rydberg dressing. We first demonstrate the creation of Ising interactions and characterize them via Ramsey spectroscopy. We observe one-axis twisting dynamics, a step towards creating spin-squeezed states with finite range interactions. By adding a periodic microwave drive, we are able to detect dynamical signatures of the paramagnetic-to-ferromagnetic phase transition. These results highlight the capability for locally and dynamically controlling the interaction strength. The apparatus constructed to realize these interactions additionally includes capabilities of quickly switching on and off the atomic interactions and dynamically changing the sign of the interactions. This work paves the way for many applications requiring spatiotemporal control of interactions in the fields of quantum simulation, quantum optimization, and quantum metrology.
