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 »

Speaker: Kirill Shtengel (University of California Riverside)
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 »

Speaker: John M. Campbell, Fermilab
The impressive size of the datasets collected by the LHC experiments, together with the ever-increasing sophistication of the accompanying analyses, means that experimental uncertainties at the level of a few percent are becoming more common. In order to maximize the information that can be... Read More »

"The Story of Love and Hate in Charged Polymers" - The interplay of electrostatic interactions and entropy leads to many unique properties of soft materials. Several of them, including complexation of oppositely charged polymers, will be described in this lecture. | Faculty Host: Warren S. Warren... Read More »

Speaker: Elbio R. A. Dagotto (University of Tennessee and ORNL)
Fermi surface nesting guided the initial theoretical studies of iron-based high critical temperature superconductors but evidence is accumulating that these materials are more complex than previously anticipated. For example, competition between antiferromagnetic and ferromagnetic tendencies leads... Read More »

Speaker: Reyco Henning, UNC Chapel Hill
ABRACADABRA is a proposed experiment to search for ultralight (10^-14 - 10^-6 eV) axion dark matter, with the ultimate goal of probing the QCD axion at the GUT scale. When ultralight axion dark matter encounters a static magnetic field, it sources an effective electric current that follows the... Read More »

"The World's Smallest Neutrino Detector" - The coherent elastic scattering of neutrinos off nuclei was first predicted 43 years ago with the realization of the neutral weak current. The predicted cross-section is the largest of any known neutrino interactions; however, the process has remained... Read More »
