Job Opportunities

Jorge Pullin "Emergence of stringlike physics from Lorentz invariance in loop quantum gravity," shows that non-local interactions like those present in string theory may be needed for loop quantum gravity to preserve Lorentz invariance. This paper by Rodolfo Gambini and Jorge Pullin received an honorable mention in the 2014 Essay competition of the Gravity Research Foundation.

John DiTusa U.S. Department of Energy Awards Dr. John DiTusa and the Louisiana Consortium for Neutron Scattering (LaCNS) a $4.9M Statewide Research Grant. Neutron scattering is one of the few techniques available that can probe the structure and dynamics of materials over a broad range of time, length and energy scales. LaCNS researchers will use the equipment and facilities and collaborate with the scientific staff at Oak Ridge National Lab in Tennessee, where they will run their experiments.

Physics Undergraduate Todd Moulder and Dr. Jonathan Dowling are featured in the article "Physical Challenge" pertaining to the LSU Ronald E. McNair Research Scholars Program.

Jiandi Zhang One exciting property of ferroelectric oxide material is its surface potential switching behavior, which can be used for ferroelectric random access memory. This switching contrast effect normaly is not stable but decays with time. In an article of Nature Scientific Report, a research group decovered a laser-induced non-destructive read-out method in one of ferroelectric oxide material (BiFeO3), which can be understood by the redistribution of the photo-induced charges driven by the internal electric field. The method resolves a long standing issue existing in ferroelectric random access memories (FeRAMs) thus offers a new oppotunity for the technological applications.

Schrodinger's Killer App The Quantum Physics and Quantum Gravity groups' work applying fundamental quantum mechanics to the development of quantum computers and to the cosmology of the early universe are highlighted in "Schrödinger's Killer App: Quantum Technology at LSU".


The Landolt Standards and 21st Century Photometry meeting will be held here at LSU, Tuesday, May 19 - Thursday, May 21, 2015. The conference will celebrate the career of Dr. Arlo Landolt. Arlo Landolt is a Ball Family Professor Emeritus with the Department of Physics & Astronomy at Louisiana State University.
