Our work on probing a Landau-Forbidden Quantum Criticality using Rydberg Quantum Simulators has been published in Physical Review Letters. This work was done in collaboration with Vldan's group in AMO as well as Max Metlitski in CMT at MIT.

Quantum simulators—carefully engineered and programmable quantum systems—provide an exciting avenue to explore the laws of nature and to realize complex physical phenomena. However, current quantum simulators still lack the sophisticated controls needed to interrogate a prepared state in depth, limiting the information that can be extracted by measurements. Here, we propose a novel measurement protocol that completely overcomes this difficulty, allowing for the extraction of arbitrary physical information. Excitingly, the protocol can be implemented with present-day technologies.
Our protocol involves introducing ancillary degrees of freedom prepared in a known state to a system of interest, letting them evolve naturally under joint quantum dynamics, then performing global measurements in a standard basis. Even though only a read more

In this collaborative project with Painter group at Caltech, we studied how to benchmark and utilize a new quantum hardware based on superconducting qubits coupled to a metamaterial waveguide. We demonstrated distinct characteristics of ergodic versus integrable quantum dynamics.

Soonwon was invited to speak as one of four finalists in the Deborah Thesis Award session at DAMOP 2020.
During the prize session, four finalists, Matthew Jaffe (UC Berkeley), Soonwon Choi (Harvard), Nathan Schine (U Chicago), and Christie Chiu (Harvard), competed one another by presenting their thesis works from respective Ph.D. institutions. Soonwon presented his work on critically slow thermalization, discrete time-crystalline order, and quantum many-body scars. While the prize eventually went to Christie Chiu for exploring the Fermi-Hubbard model wiht ultracold atoms, it was such a wondeful opportunity for all four finalists to share their Ph.D research with a broad audience. The presentations have been recorded and are available online here.

Phys.org covered our work on the observation of discrete time-crystalline order in black diamond!

Our work on the observation of discrete time-crystalline order in black diamond experiments made the cover of Nature. This work reports the first experimental observation of time-crytalline order together with a concurrent work done in Monroe's group at the University of Maryland. In contrast to the fully controllabe small-size quantum simulator used by Monroe's group, we utilized an ensemble of strongly interacting electronic spin degrees of freedom in diamond to simulate the exotic physics. Chetan Nayak wrote a very nice News & Views article on these complementary works.
