Upcoming Events

The JILA Postdoc Group invites all postdocs to a panel discussion with JILA fellows Xun Gao, Taeho Ryu, and Bryan Changala. During the panel, the fellows will discuss their recent experiences in the academic job market. This is a prime opportunity for postdocs who are starting to think about the academic job market, or who are ready to apply, to ask the panelists questions about the details of the process. Lunch will be provided after the panel.

Active systems are driven out of equilibrium by exch

Strain is powerful for discovery and manipulation of new phases of matter; however, elastic strains accessible to epitaxial films and bulk crystals are typically limited to small, uniform, and discrete values. In this talk I will describe our progress on synthesizing single crystalline membranes of Heusler compounds, which enable large continuously tunable strains and strain gradients via bending and rippling. This synthesis strategy borrows ideas from remote epitaxy and van der Waals epitaxy on graphene, and I will describe our current understanding of the growth mechanisms.

In this seminar, I present recent results on the structure, variability and energetics of the far upper atmosphere found by the method of solar occultation, where atmospheric properties are inferred using sunlight as it passes through an atmosphere. The extreme ultraviolet (EUV) band is strongly absorbed in the thermosphere, enabling EUV occultations to provide a unique window into a sparsely observed region of the atmosphere.

Strong light-matter interactions hold great promise for modulating molecular and material properties, including chemical reactivity, energy transfer, and charge conductivity, via polaritonic states. In realistic chemical and material systems, disorder arising from thermal fluctuations and structural defects is inevitable and has a significant impact on the polaritonic state. However, disorder is often considered a perturbative effect and is usually omitted from models of light-matter dynamics and spectroscopy.

The dynamics of Earth’s radiation belts remain one of the central challenges in space weather research. Despite decades of satellite observations, predicting when and how the belts will intensify or decay remains difficult. This seminar will discuss recent work combining multi-mission datasets from 36 multi-agency satellites to produce the highest-resolution phase space density (PSD) observations of the outer belt to date, and how these have been used to identify dominant acceleration and loss mechanisms.

As educators, we would like to prepare our students for 21st century physics careers. Overall, to ensure all students will become successful scientists, physics departments need to be able to provide evidence to make sure that we are reaching these goals. The field of Physics Education Research has made major contributions to various educational practices and materials to reform instruction in order to recruit and retain more students.

This century is witnessing a second quantum revolution, and quantum sensing represents an area in which chemists can make significant contributions. Achieving quantum sensing requires more than precise control of quantum states at the molecular level; it is also crucial to organize molecular qubits so that they function effectively in complex environments. In this seminar, I will discuss materials chemistry approaches to molecular quantum sensors, focusing on their extension from biological systems to engineered materials.

The Will Lab studies quantum systems of ultracold atoms and molecules. The lab cools atoms and molecules to temperatures less than a millionth of a degree above absolute zero, where atomic behavior is fully governed by quantum mechanics. Under these conditions, the lab controls individual quantum particles and their interactions with high precision using atomic physics tools, enabling novel platforms for many-body quantum physics, quantum simulation, quantum computing, and quantum optics.

I will discuss the standards of time and frequency and how these standards have evolved over the centuries. I will present the current definitions of time and frequency and how these definitions are likely to evolve in the coming years.
