Brownian Motion of a Resonator Linked to a Spatially Varying Thermal Bath

When
-

We are excited to announce the first CU Phonon Club seminar of the semester. Please join us for a great talk, interesting discussion, and FREE FOOD. We are pleased to feature Dr. Ravid Shaniv from Prof. Regal's group who will be presenting their recent work. Also, we are planning on hosting two more talks this semester. Feel free to pass this email along to any others who may be interested. We hope to see you on Wednesday!

The New Age of Exploration and Science at the Poles of the Moon

When
-

Abstract: More than one hundred years ago, exploration of the Earth's polar regions reached a fever pitch. Competition for the South Pole ultimately led to scientific discoveries whose legacy persists to the present day. Similarly, the poles of the Moon have become a new frontier for science and exploration. Perennial shadows in near-polar craters -- many of them named for famous Antarctic explorers -- remain cold enough, < 100 K, to trap water and other volatiles for billions of years. Where might these volatiles come from?

Vibrational Spectral Signatures and Ultrafast Dynamics of Strong H-bonds Investigated with Cryogenic Ion and 2D IR Spectroscopies

When
-

Abstract: H-bonding interactions and proton transfer processes play central roles throughout chemistry and biology. Spectroscopic studies that directly probe strong H-bonds and proton transfer reactions, however, remain a formidable experimental challenge. We aim to characterize vibrational spectral signatures and dynamics of strong H-bonds by complementing high-resolution gas-phase techniques (cryogenic ion spectroscopy) with ultrafast time-resolved solution-phase experiments (transient absorption, 2D IR).

A versatile quantum playground with solid-state quantum emitters

When
-

Abstract: Solid-state quantum emitters have attracted much attention as an integrated source of photonic and spin qubits, which are basic elements for a range of quantum applications. Recent advances in the generation, manipulation, and integration of these emitters have demonstrated a variety of quantum resources: bright quantum light sources, quantum memories, and spin-photon interfaces. In particular, controllable quantum emitters in photonic cavities or waveguides enable scalable quantum interactions between multiple photons and emitters.

Complex and Heterogeneous Biophysical Systems Studied with 2DIR

When
-

Abstract: I will present three projects. In the first two, we used two-dimensional infrared (2DIR) spectroscopy to study properties of some complex peptide and protein assemblies 1: Proline-arginine (PR) dipeptide repeats are an example of a growing number of intrinsically disordered proteins (IDPs) known to assemble into membrane-less organelles by liquid-liquid phase separation (LLPS), and has also been implicated in the disease mechanism of Amyotrophic lateral sclerosis (ALS).
