Assistant Professor Position

Tuesday, October 15, 2013

The Department of Physics and Astronomy at the University of Mississippi invites applications for a tenure-track position in physics at the rank of assistant professor for the Fall of 2014. The emphasis of this position is on developing an externally funded research program and laboratory capable of supporting and leading graduate students to a Ph.D. A competitive startup package is available in the first three years. The University currently has strong programs in atmospheric physics, biomedical ultrasonics, condensed matter physics, gravitation, high-energy physics, and physical acoustics. A Ph.D. in Physics or a related field and one year postdoctoral experience is required. Faculty members are expected to contribute to the teaching and service activities of the Department and the University. Teaching duties include three courses a year at the undergraduate and graduate level.

Interested candidates should apply online at (posting 4078). A curriculum vitae, three letters of recommendation, a statement of teaching philosophy, and a detailed proposal for developing their research program should be sent directly to: Search Committee Chair, Department of Physics and Astronomy, The University of Mississippi, P.O. Box 1848, University, MS 38677. Recommendation letters should address the candidate’s qualifications and assess the quality of the proposed research plan. The search will remain open until an adequate applicant pool is established, or until the position is filled.

The University of Mississippi is an EEO/AA/Title VI/Title IX/Section 504/ADA/ADEA Employer.

Postdoctoral Position in Theoretical Physics and Astrophysics

Monday, October 7, 2013

The University of Mississippi invites applications for a postdoctoral
position in the area of Theoretical Physics and Astrophysics. The

track record in one or more of the following research areas:
gravitational-wave source modeling and astrophysics, numerical
relativity, post-Newtonian theory, alternative theories of gravity,
perturbation theory of stars and black holes.

The Gravitational and High-Energy Theory Group at the University of
Mississippi is active in various areas of theoretical and experimental
gravity, and is part of the LIGO collaboration. Members of the group
include Emanuele Berti, Luca Bombelli, Marco Cavaglia, Alakabha Datta
and Tibor Torma, adjunct professors Vitor Cardoso and Ulrich Sperhake,
three postdocs and several graduate students.

The successful applicant is expected to engage in a collaborative
research program involving several institutions, including Caltech and
Princeton in the USA, Lisbon, Cambridge, Rome and Aveiro in Europe,
and Para’ University in Brazil (among others).

A curriculum vitae (including a list of publications and a statement
of research interests) should be sent to the following e-mail address:

Please use the subject “Gravitational theory postdoc”. Applicants must
also arrange to have at least three recommendation letters to be sent
to the same email address.

Applications must be submitted as soon as possible, and no later than
12/31/2013. Late applications may be considered until the position is

The gravity group welcomes Dr. Shivaraj Kandhasamy

Friday, October 4, 2013

UMiss is happy to welcome Dr. Shivaraj Kandhasami as new postdoc in the LIGO group. Shivaraj comes to us from the University of Minnesota, where he has recently obtained a doctorate in physics with a thesis on LIGO’s search for stochastic gravitational waves. Dr. Kandhasamy will reside at the Livingston LIGO Lab to work on detector characterization of the Advanced LIGO instrument, data analysis, and outreach. Welcome, Shivaraj!

Two papers in Physical Review Letters

Thursday, July 11, 2013

Two papers by our group have been accepted in Physical Review Letters in the past few weeks.

The first paper, Gravito-Electromagnetic Perturbations of Kerr-Newman Black Holes: Stability and Isospectrality in the Slow-Rotation Limit , presents the first calculation of the coupled gravitational/electromagnetic oscillation modes of charged, rotating black holes. This is a difficult technical problem that we solved by working in the limit where the black hole spins slowly. Quite interestingly, we found that oscillations of opposite parity have the same oscillation frequencies up to linear order in the black hole rotation.

The second paper, Universality, maximum radiation and absorption in high-energy collisions of black holes with spin, is an interesting tale of “black hole cannibalism”: using numerical simulations, we showed that when two black holes collide at speeds close to the speed of light they “eat” (absorb) about half of the gravitational radiation produced in the process. This sets an upper limit to the maximum energy that can be radiated in high-speed black hole encounters. A story about this paper can be found in the Ole Miss News website.
