On April 1, 2022, oSTEM is excited to bring you the Out in STEM Panel, where we'll be talking with STEM professionals from various different disciplines about their experiences being LGBTQ+ in the STEM workplace! This event is open to all CU students, faculty, and staff, and registration is open now!

In situ transient absorption spectroscopy during materials formation

When
-

Abstract: Molecules, polymers, and nanocrystals can form the active layer in electronic devices such as photovoltaics and light-emitting diodes. Their electronic structure and excited state dynamics dictate their function and suitability for these applications. Transient absorption (TA) spectroscopy is used to measure these properties, and has provided remarkable insights into the behavior and function of electronic materials.

Nonabelian Hall conductance in general dimensions as an invariant of the interacting ground state wavefunction

When
-

Abstract: The long-wavelength response of a gapped many-body system in D spatial dimensions with a Lie group symmetry G to an external gauge field is believed to be described by a Chern-Simons action in dimension D+1. Since the coefficient of the Chern-Simons action is quantized, it is a topological invariant (i.e. is unchanged under deformations of the Hamiltonian which do not close the gap).

Earth’s Electromagnetic Oceans: Tsunamis and Tides

When
-

Seminar Abstract:

More than 70% of Earth’s surface is ocean covered. In the past, this was seen as a challenge for geophysicists dependent on on-land observatories. But now, largely thanks to an enduring era of reliable low Earth orbit satellite magnetometer data, this challenge has become a boon: 70% of Earth’s surface is covered by a moving, electrically conductive fluid that creates detectable electromagnetic signals which can then be used to study the solid Earth, the oceans themselves, and natural hazards such as tsunamis.

Degenerate Polar Molecules with Controlled Interactions and Reactivity.

When
-

Abstract: Ultracold polar molecules, which have complex internal state structures and dipole moments tunable with external electric fields, are a promising system for studying many-body physics. Producing degenerate molecules and observing quantum effects has been prevented by high initial temperatures and rapid loss from chemical reactions. In this talk, I describe the creation of degenerate potassium-rubidium (KRb) molecules by pairing in an atomic mixture.
