The Weld group uses the tools of experimental atomic physics to attack problems relevant to the many-body quantum mechanics of condensed matter. Research interests include experimental ultracold atomic physics, quantum simulation, optical lattices, trapping of alkali and alkaline earth atoms, novel quantum phases, nonequilibrium dynamics, new cooling techniques, analogies between condensed matter and atomic physics, quantum metrology, and micron-scale force sensing.

What's New

This recent article and video, starring several Weld group members, describes the outreach program Physics Circus.

Ruwan's paper on a microcapillary-based oven nozzle is published in RSI.

The Weld group is part of the brand-new California Institute for Quantum Emulation (CAIQuE), funded by a President's Research Catalyst Award. This five-campus collaboration includes experiment and theory groups at UCLA, Berkeley, Irvine, UCSB, and UCSD, and will focus on quantum simulation of many-body systems.

The Office of Naval Research has funded our proposal entitled Quasiperiodicity, Interactions, and Topology in Tunable Quantum Materials. We look forward to working with ONR!

Slava's paper on a permanent-magnet-based "self-assembled Zeeman slower" is the cover article in Journal of Physics B: Atomic, Molecular and Optical Physics.

David has received a Presidential Early Career Award for Scientists and Engineers (PECASE). Many thanks to the white house and the Army Research Office! (announcement)

Motivated graduate students and postdoctoral researchers interested in working with our group should email David Weld.
