Two physics Ph.D. students, Marguerite Brown and Bryce Yoshimura, have been named 2013-14 ARCS Fellows. Marguerite, who was also a 2012-13 ARCS Fellow, will be continuing her interdisciplinary research in the Blair lab on how microtubules, which provide structural support in cells, organize into different types of structures under different mechanical conditions. Bryce is conducting theoretical research in the Freericks group on using ion trap quantum simulators to study frustrated quantum magnetism.
Prof. Freericks led the theory effort on a University of Maryland/Georgetown University team that examined how to scale up ion trap quantum simulators to study complex frustrated spin states. The work was published in the May 3 edition of Science viewed as the top general science journal in the world.
Prof. David Egolf and a team of three former Georgetown undergraduates, Edward Banigan (C'07), Matthew Illich (C'11), and Derick Stace-Naughton (C'11), have had their research featured on the cover of the prestigious journal Nature Physics. They uncovered dynamical mechanisms behind the intriguing phenomenon of granular "jamming", in which free-flowing grains (sand, oranges, pharmaceuticals, etc.) develop into a disordered, solid-like state when the density is high enough.
Semiconducting molybdenum disulfphide is an attractive material for novel
nanoscale optoelectronic devices primarily due to its inherently large
direct bandgap. However, a major technological hurdle has been the
inability to create solid-state hole transport in MoS2 transistors. A
recent breakthrough achieved by members of the Physics Department will
appear in Nature – Scientific Reports, entitled “Electron-hole transport
and photovoltaic effect in gated MoS2 Schottky junctions”. The author
list includes a diverse group – a visiting engineering professor from
