Speaker: Abhishek Mohapatra
Axions are a strongly motivated candidate for dark matter. In relativistic field theory, axions are described by a real scalar field, whose self-interaction potential is a periodic function of the scalar field. If the dark matter in the universe is made of axions, then they are highly... Read More »

Halide perovskites have recently emerged as a new family of semiconducting materials that are revolutionizing the field of photovoltaics. The rapid development of perovskite solar cells is being led by the advances in microstructural/compositional engineering of perovskite thin films. In this... Read More »

Deans' Lecture on the Broader Impacts of Basic Science - "The Importance of Communication: From Stadium Waves to the Heart" - Individuals need communication to act collectively. Collective action can be impressive, as in a stadium wave, and it can be essential, as in our heartbeats. With each beat... Read More »

Speaker: Seyed M. Koohpayeh (Johns Hopkins University)
Almost every new technological innovation depends significantly upon the discovery of new materials with novel physical properties. The development, growth and structural analysis of materials, particularly in the form of single crystals, establishes how materials work at a fundamental level, helps... Read More »

Speaker: Naoko Kurahashi Neilson (Drexel University)
"Neutrino Astronomy at the South Pole with IceCube" The Universe has been studied using light since the dawn of astronomy, when starlight captured the human eye. The IceCube Neutrino Observatory, located at the geographic South Pole, observes the Universe in a different and unique way: in high-... Read More »

Speaker: Christopher Monahan
First principles calculations of light cone physics, such as the Bjorken-x dependence of hadron structure, have been a long-standing challenge for Euclidean field theory. This year marks a significant milestone: the first determinations of parton distribution functions, which capture the... Read More »

Speaker: Lin Dai
Jet substructure provides us with a new way of probing the mechanisms of quarkonium production. We study quarkonium production within jets based on the fragmenting jet function (FJF) which describes the distribution of a quarknium in a jet with certain jet shape. FJF incorporates quarkonium...

Abstract : I discuss the recent theoretical observation of Z_3 -valuedparticle-vortex braiding phases in high density quark matter.Certain mesonic and baryonic excitations, in the presence of asuperfluid vortex, have orbital angularmomentum quantized in units of 1/3. Such non-local... Read More »

Speaker: Juergen Eser, Frankfurt University
We compute the low-energy limit of the O(4)-symmetricquark-meson model as an effective field theory for QuantumChromodynamics within the Functional Renormalization Group (FRG)approach [1]. In particular, we analyze the renormalizationgroup flow of momentum-dependent pion self-interactions beyond... Read More »
