Abstract: Understanding emergent behaviors in strongly interacting quantum systems is a frontier area of condensed matter physics. However, simulations of quantum many-body systems on classical computers are not scalable beyond a few dozen particles. This motivates the development of quantum simulators, highly controllable analog quantum computers specifically designed to study certain types of problems in condensed matter physics.

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:

Human curiosity and interest in the near-Sun environment date back millennia, as shown by numerous historical records. The confluence of these motives results from our existence and life depending upon the Sun. Life on Earth (and maybe elsewhere in the solar system and on other habitable stellar worlds) might never have kicked off if not for solar magnetic activity in conjunction with the Sun’s light and heat.

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. To date, a quantum memory stable against finite-temperature effects is only known in four spatial dimensions or higher.

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.
