Abstract: “Working in policy” is a phrase we hear tossed around, but what does that really entail? What are the professional roles that exist in science policy?
Hello!
The Graduate Association of Students in Physics (GASP) and the JILA Association of Graduate Students (JAGS) are excited to announce the next session of the Graduate Student Seminar Series! Please join us on Thursday, March 13th, at 12:30 in the JILA Auditorium for lunch, with the talks beginning at 12:45.
The talks for this session are:
Light-assisted Collisions in Optical Tweezers - Steven Pampel, Regal Group
Observation of field-split crystal electric field levels in CsErSe$_2$ - Hope Whitelock, Lee Group
Single atoms and molecules are the emerging frontier in engineering applications as they represent the ultimate limit of modern electronic and photonic devices. While controlling at these extremely small scales have become a reality, the understanding of energy transport, conversion, and dissipation properties of these systems is falling behind due to the lack of experimental tools.
March 10th, our colloquium will feature six short research talks by current APS 3rd years. Come help us celebrate ongoing student research in APS!
- Judit Bergfalk, Multi-point measurements of plasma in the Martian magnetosphere
- Anna Zuckerman, Electron Beam Simulations for Substellar Atmospheres
Abstract: Over forty years ago, Nielsen and Ninomiya proved that chiral modes cannot exist in discrete systems without a m
Abstract: Planetary exploration has unveiled environments that could support life today, or in the past, or contain the ingredients of life. Mars was once habitable; Enceladus’ ocean is today, Europa is a question mark, and Bennu contains most of the basic key monomers of life in abiotic form. I will discuss how this all fits together.
Abstract: Prominent among biophysical techniques is the optical trap, for which Arthur Ashkin (Bell Labs) received a Nobel Prize in 2018. Among the successes of optical traps have been direct measurements of the steps taken by biological motor proteins, such as kinesin, and by nucleic-acid enzymes, such as RNA polymerase. Optical traps facilitate studies of replication, transcription, and translation at the single-molecule level. They’ve been especially useful in mapping the free-energy landscapes of folding by small, structured RNAs.
Abstract: For the past four decades, the Space Telescope Science Institute has served as the bridge between NASA's flagship astrophysics missions and the scientific community through its role as the science operations center for Hubble, Webb, and Roman. The Hubble Space Telescope is celebrating its 35th year of operations, and continues to lead innovative new discoveries with its ultraviolet-optical capabilities and decades of high precision data.
Abstract:
Future electronic and quantum devices will require near-atomically-precise nanofabrication processes, but present plasma processing methods create a variety of imperfections that limit device performance. In this talk, I will present atomic layer etching processing for materials including superconducting titanium nitride, lithium niobate, and compound semiconductors which enable etching with Angstrom-scale precision. I will also describe our efforts to validate the process improvements at the device level.

Abstract: The modern understanding of quantum materials traces back to Felix Bloch, who first applied quantum mechanics to crystalline lat
Abstract: The Transiting Exoplanet Survey Satellite (TESS) is NASA’s wide-field optical astrophysical observatory exploring the bright and time-variable sky. Since its launch in 2018, TESS has discovered over 500 confirmed exoplanets and over 6000 additional candidates await confirmation. Dozens of these planets’ atmospheres have been or soon will be explored by the Hubble and Webb Space Telescopes.
Abstract: The ocean absorbs most of the heat and about a quarter of the carbon emissions caused by human activities. These anthropogenic perturbations significantly influence the ocean circulation, with direct and critical implications for the climate system. The ocean circulation is characterized by diverse turbulence regimes that span a vast range of spatial and temporal scales.
