Pushing LIGO’s quantum limits
When
-
Abstract: The Advanced LIGO detectors operate at a regime where quantum uncertainty imposes a fundamental limitation to sensitivity in the form of quantum shot noise and quantum radiation pressure noise. During the last gravitational wave observing run O3, the LIGO and Virgo detectors used quantum states of light known as squeezed states of light in order to reduce high frequency quantum shot noise.
Designing sensors with tensioned silicon nitride micromechanical resonators
When
-
Abstract: Mechanical resonators based on stressed silicon nitride have both exemplary optical and mechanical properties. Through targeted shaping of the resonator geometry, the dissipative properties of these resonators can be enhanced, yielding micromechanical devices that maintain coherence for up to billions of oscillation periods.
Single molecule ligand binding kinetics and environmental adaptations in lysine riboswitches
When
-
Abstract: Riboswitches are important RNA structures in bacteria and some eukaryotes that can bind a ligand to toggle between conformations that allow or terminate transcription, translation, or splicing. We study folding kinetics and thermodynamics in the B. subtilis and T. maritima lysine riboswitches via single molecule TIRF microscopy. We show that riboswitch folding is exothermic with a large entropic cost, which we attribute to increased binding pocket rigidity upon lysine binding.

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!
Heralded Spectroscopy - a new probe for nanocrystal multiexciton photophysics
When
-
Abstract:
Emitters of quantum light are at the core of quantum optic science and a key resource for emerging classical and quantum technologies. Yet, to date, the tools available to study multiple-photon quantum light sources, specifically temporally and spectrally in parallel, have been limited. A prominent example is multiply-excited semiconductor quantum dots - an intriguing system that features rich physics and technological potential but lacks direct observation techniques.
