The life & flow of polarons: from nonequilibrium formation and relaxation to equilibration in the thermodynamic limit

When
-

Abstract: Polarons, quasiparticles composed of an electronic excitation and the material deformation these cause in a solid or liquid, are ubiquitous. Understanding and controlling their formation, nonequilibrium relaxation, and motion are essential in developing next-generation photocatalysts, energy conversion devices, and even superconductors. In this talk, I introduce some of our recent theoretical advances that enable us to probe the exact quantum dynamics of Holstein polarons subject to dispersive phonon baths in small lattice models to the thermodynamic limit.

Intentionally Designing Models for Learning Tasks with Quantum

When
-

In this seminar talk, the speaker will begin with a brief overview of how quantum computation has led to an exciting new set of features for designing generative models, emphasizing that these features should be utilized with intention to help researchers obtain a better understanding of how quantum is useful and for what specific learning tasks.

Studying exoplanet atmospheres in the era of JWST

When
-

Abstract: The recent launch of JWST is revolutionizing our understanding of exoplanet atmospheres by providing observations at an unprecedented level of detail. In this talk, I will discuss two methods for studying the atmospheres of exoplanets with JWST. First, I will discuss the potential for spectroscopic eclipse mapping with JWST. Spectroscopic eclipse mapping is the only observational technique which allows for simultaneous resolution of the atmosphere in three spatial dimensions: latitude, longitude, and altitude.
