Abstract: The presentation will be focused on the development and application of relativistic

electronic-structure methods aiming to extend accurate quantum chemistry to heavy

Abstract: Nonlocal games yield an unusual perspective on entangled quantum states. The defining property of such games is that a set of players in joint possession of an entangled state can win the game with higher probability than is allowed by classical physics.

Abstract: Chaotic lattice models at high temperature are generically expected to exhibit diffusive transport of all local conserved charges. Such diffusive transport is usually associated with overdamped relaxation of the associated currents. We argue that by appropriately tuning the inter-particle interactions, lattice models of chaotic fermions at infinite temperature can be made to cross over from an overdamped regime of diffusion to an underdamped regime of "hot band sound".

CubeSats are NASA’s newest—and smallest—class of spacecraft.  These nanosatellites, often about the size of a cereal box, enable rapid, low-cost exploration of the space environment around Earth and beyond.

Synopsis: The Fordyce lab works to understand protein-DNA binding interactions to understand and engineer pathways related to metabolism and protein signaling. The lab focuses on obtaining the thermodynamic and kinetic constants of these molecular interactions using microfluidics and extensive hardware (MITOMI and HT-MEK, MRBLEs, Dropception) 
 

Abstract: The advent of femtosecond Ti:Sapphire lasers has enabled transformative advances in high field nonlinear optics and intense laser-matter interaction physics. Theories predict that many high field phenomena such as high harmonic generation favor middle IR laser wavelengths in terms of extending the high energy cutoff. The invention of middle IR Cr2+-doped ZnS and ZnSe lasers in the 1996s by the research team of William Krupke at the Lawrence Livermore National Laboratory has coincided with an explosive progress of ultrafast Ti:Sapphire laser technology.

Abstract: An interesting problem in the field of quantum error correction involves finding a physical system that hosts a "passively-protected quantum memory,'' defined as an encoded qubit coupled to an environment that naturally wants to correct errors.

Abstract: How quantum mechanics governs space, time and gravity is a longstanding mystery. Inspired by properties of black holes, recent progress has been made relating quantum spacetime to properties of quantum information and quantum computation such as entanglement entropy, computational complexity and quantum error-correcting codes. I will review some of these developments and discuss some of my own work on geometric realizations of measures of entanglement.

Synopsis: The main goal of the Silva lab is to understand ubiquitin pathways in response to the oxidative stress response pathway with the goal being to develop ubiquitin centered therapies to counter cancer cells. The lab uses molecular biology tools, protein biochemistry, proteomics, structural biology, and next generation sequencing to investigate ubiquitination in yeast cells.

Abstract:

Master storyteller Susan Marie Frontczak, playing the part of Mary Shelley, tells how the famous and familiar story of Dr. Frankenstein's creature is related to ethical issues that arise when scientific pursuits introduce unexpected results.

Abstract:  Look out your window and you might see a conifer tree covered with snow. Ever wonder how the needles stay alive all winter long as the temperature dips below freezing? Like pine trees, some organisms possess molecules that naturally enable them to withstand cold. Scientists have copied nature to develop methodology to cryopreserve biological materials, storing them at low temperatures for future use. The first step in any cryopreservation protocol involves dosing the sample with a cocktail of cryopreservation agents, molecules that help them stay viable.
