"The COHERENT Neutrino Program at the ORNL Spallation Neutrino Source"


Tyler Johnson , Duke University
[Host: Craig Group]
ABSTRACT:

The discovery of coherent elastic neutrino-nucleus scattering (CEvNS) was made by the COHERENT Collaboration in 2017 using a CsI[Na] scintillating crystal at Oak Ridge National Laboratory's Spallation Neutron Source (SNS). This observation was made over 40 years after the theoretical prediction by Freedman et al. and consists of a neutral-current neutrino-nucleus interaction on an entire nucleus as a whole. The CEvNS process is the dominant scattering mode below 100 MeV and serves as a fertile testbed for precisely examining the Standard Model and has applications in nuclear reactor monitoring and stellar astrophysics. COHERENT built out the CEvNS physics program to include detector systems using liquid argon (CENNS-10), germanium (GeMini) and NaI[Tl] crystals (NaIvEte)--of which liquid argon successfully yielded an additional CEvNS measurement. The variety of media studied within the COHERENT detector suite works towards establishing the predicted N^2 dependence of the CEvNS cross section. Additionally, the COHERENT Collaboration houses several detector systems aimed at elucidating inelastic neutrino-nucleus interactions in support of CEvNS searches and as standalone investigates of neutrino-induced nuclear reactions. This presentation will consist of both the published results and the ongoing work being done on new detectors to further advance the physics goals of the collaboration.

"Enhanced associative memory, classification and learning with active dynamics"


Suri Vaikuntanathan , University of Chicago
[Host: Marija Vucelja ]
ABSTRACT:

Motivated by advances in the field of active matter where non-equilibrium forcing has been shown to activate new assembly pathways, here we study how  non-equilibrium driving in prototypical   memory formation models  can affect their information processing capabilities. Our results reveal that activity can provide a new and surprisingly general way to dramatically improve the memory and information processing performance of the above described systems without the need for additional interactions or changes in connectivity. Non-equilibrium dynamics can allow these systems to have memory capacity, assembly or pattern recognition properties, and learning ability, in excess of their corresponding equilibrium counterparts. Counter-intuitively, in some cases, dynamics with non-equilibrium noise-sources can even have a higher memory capacity than  zero temperature equilibrium systems that are not subject to any noise.  Our results demonstrate the  generality of the enhancement of memory capacity arising from non-equilibrium, active dynamics. These results are of significance to a variety of processes that take place under nonequilibrium dynamics, and involve information storage and retrieval, as well as in silico learning and memory forming systems for which nonequilibrium dynamics may provide an approach for modulating memory formation.

"The Heavyweight W boson - an Upset to the Standard Model of Particle Physics"


Ashutosh Kotwal , Duke University
[Host: Craig Group]
ABSTRACT:

The Standard Model of particle physics has been a crowning achievement of fundamental physics, culminating in the discovery of the Higgs boson in 2012. As a quantum theory of the building blocks of matter and forces, it has been one of the most successful theories in science. The recent measurement of the mass of the W boson disagrees with the theory prediction. This upset to the Standard Model may point towards exciting new discoveries in particle physics in the coming years. We will discuss the Standard Model, the crucial role of the W boson, and how it has become the harbinger of new laws of nature.

"You have your physics results. Now what?"


Sami Mitra , PRL
[Host: Avik Ghosh]
ABSTRACT:

In a talk that I am hoping will quickly morph into a free-flowing Q and A session, I will discuss the roles of journals in general and PRL in particular in disseminating physics results through a cascading sequence involving journal editors, referees, conference chairs, journalists, department chairs, deans, funding agencies, and others. While some of the essential tools of physics dissemination are unchanged, the arrival of social media, search engines, and electronic repositories have us in a state of flux.
