"Noise-driven dynamics in far-from-equilibrium systems" - The dynamical behavior of many far-from-equilibrium systems is crucially impacted by the interplay of noise and deterministic degrees of freedom. Examples of noise-enabled dynamics occur throughout the natural sciences including biophysical... Read More »

Speaker: Dr. Matt Sievert (Theoretical Division of Los Alamos National Laboratory)
Because parton distribution functions (PDFs) are measured at finite center-of-mass energies, they must always be extrapolated to high-energy asymptotics where x goes to zero. This extrapolation is especially important for the determination of sum rules, such as the contribution to the proton spin... Read More »

Speaker: Ashley Jones, NASA Goddard Space Flight Center
Electron microbursts are rapid bursts of precipitation in radiation belts of the Earth that occur on the scale of ~tens of ms. Studies suggest microbursts may be able to empty the radiation belts on the time scale of a day and are associated with chorus waves. We will go over the basics of... Read More »

Speaker: Dmitri Khveshchenko (UNC Chapel Hill)
We discuss higher dimensional generalizations of the 0+1-dimensional Sachdev-Ye-Kitaev (SYK) model. Unlike the previous constructions where multiple SYK copies would be coupled via some spatially short-range one- and/or q-particle random hopping processes, this study focuses on the algebraically...

"Protecting Quantum Information" - The interaction of a quantum system with its environment leads todecoherence and is the most important challenge facing the construction of a quantum computer. My research group studies two methods for reducing decoherence: quantum control and quantum... Read More »

Speaker: Giuseppe Calajo (TU Wien)
Slow-light waveguide QED refers to a regime where the maximal photonic group velocity is significantly reduced compared to free space. Such conditions could be achieved in one-dimensional photonic periodic structures such as photonic crystals, coupled-resonator arrays, modulated fibres, etc. In... Read More »

"Quantum Critical Points: Bridges Across Energy Scales" - In physics we often look for paradigms that unify physical phenomena at different energy scales. Quantum Critical Points (QCPs) provide such a paradigm by bridging concepts of phases and phase transitions of a physical system with notions of... Read More »

Speaker: Mayra Cervantes, Duke University
Predicted more than 43 years ago as an immediate consequence of the existence of neutral currents in neutrino-induced interactions, Coherent Elastic Neutrino-Nucleus scattering (CEVnS) had eludeddetection until very recently. I will discuss the recent results from the COHERENT collaboration that... Read More »

Non-Abelian anyons are widely sought for the exotic fundamental physics they harbour as well as for their possible applications for quantum information processing. Currently, there are numerous blueprints for stabilizing the simplest type of non-Abelian anyon, a Majorana zero energy mode bound to a... Read More »

"Cracking the Standard Model of Particle Physics" - The study of fundamental particles, at a multitude of experiments over many decades, led to the emergence and triumph of the Standard Model (SM) of particle physics. Despite the overwhelming success of this model, it still leaves many questions... Read More »
