Fall, 2021

September 17th

Speaker: TCNJ Physics Summer Research Students

Topic: Summer Research Experiences

Abstract:

Mary Mcmullan: 
“Integrating SESAME in FLASH & Simulations of Supersonic Turbulence”
Abstract:  This summer, I have been incredibly grateful to work alongside Professor Petros Tzeferacos and with a wonderful group of people working at the Flash Center at the University of Rochester. For my main project, I worked in collaboration with graduate student Pericles Farmakis. Our objective was to integrate the SESAME Equation of State Tabulated Database into the FLASH code. The FLASH code is a multi-physics high-performance simulation code developed by the Flash Center. FLASH solves extended systems of radiation magneto-hydrodynamics(MHD), applied in a number of different application domains, from astrophysics, to computational fluid dynamics, and to high energy density physics.
Dean Klunk: 
“Do elementary schools ignore physics?”
Abstract: This summer, I did a MUSE research project here at TCNJ with Dr. Richards. We examined the elementary school curricula of 32 school districts and identified themes associated with physics vs. other science disciplines to measure the relative prevalence of physics.
John Mahoney:
“Temperature dependence of perovskite solar cells”
Abstract: I spent my summer doing an REU at The University of Oklahoma under Dr. Ian Sellers. Our research focused heavily on perovskite solar cells, where we observed various effects of how these photovoltaics behave across a range of temperatures from 4K to 300K.
Mario Gallardo:
“A Method to Evaluate Cumulative Dose on TSET Patients on Patient Finite-Element Models using Cherenkov Imaging”
Abstract: The program I participated in this summer is called SUPERS, which stands for Summer Undergraduate Program for Educating Radiation Scientists. This is open to mainly rising juniors and seniors. One of their specialties was medical physics, and I worked under that subdivision in the radiation oncology department. My project involved patient modeling and imaging for electron beam therapy treatment. I worked in the Dr. Tim Zhu lab at the University of Pennsylvania, Perelman Center for Advanced Medicine.

Time: 12:30 PM

Topic: Skyrmions and Biskyrmions in Magnetic Films

Speaker: Dr. Daniel Capic (Visiting Professor in the TCNJ Physics Department)

Abstract: Skyrmions have garnered significant attention in condensed matter systems in recent years.They were originally studied in the context of high-energy physics by Tony Skyrme as topologically non-trivial solutions that arose from the addition of a constrained term to the Lagrangian. Later, Belavin and Polyakov found that in ferromagnetic films, they appear as defects in the ferromagnetic order which otherwise prefers the alignment of all the spins in one direction. These defects are quasiparticles that are characterized by an integer topological charge. Since skyrmions can be as small as a few lattice spacings, are easy to create and manipulate, and can persist on long time scales, they have been looked to for their use in computing applications. This talk will describe what a skyrmion is and the meaning of “topological charge”, the properties of skyrmions and related topologically non-trivially quasiparticles, and other findings I published in the course of completing my PhD.

Bio: Dr. Capic is from Staten Island, NY and went to Stony Brook university for undergrad, which is part of the state university of New York (SUNY) system where he double majored in physics and math. He did his PhD at the CUNY Graduate Center (city university of New York). He studies theoretical condensed matter. He currently studies skyrmions, which are objects with a non-trivial topology that can appear in magnetic systems.
