Group Meetings
Published by admin on Monday, March 1, 2010
The Gravity Group at UMississippi has a regular weekly scheduled meeting throughout the year to discuss current research progress, topics of interest and new papers. Typically, each week, two members of the group each make a short presentation, either about their current area of research or a paper that has attracted their interest.
For Summer 2025, the Group meets on Wednesdays at 11AM-12PM for a journal club and on Fridays at 11AM-12PM for a research update, both a scheduled ca. half hour presentation and room for free-form updates. The schedule of speakers for this period is:
Group Meeting Schedule(*subject to change)
| Date | Paper Presentation | Research Presentation |
|---|---|---|
| May 14 & May 16 | arXiv discussion | Nathan |
| May 21 & May 23 | Dipika | Purnima |
| May 28 & May 30 | Subhayu | Nauman |
| Jun 4 & Jun 6 | Amitesh | Leo (paper) |
| Jun 11 & Jun 13 | seminar | seminar |
| Jun 18 & Jun 20 | Arindam | James (paper) |
| Jun 25 & Jun 27 | seminar | Subhayu |
| Jul 2 & Jul 4 | Gokul | [4TH OF JULY] |
| Jul 9 & Jul 11 | Nauman | Aniket (paper) |
| Jul 16 & Jul 18 | Nathan | Amitesh |
| Jul 23 & Jul 25 | Purnima | Dipika |
| Jul 30 & Aug 1 | Anuradha | Aniket |
| Aug 6 & Aug 8 | seminar | Arindam |
The group also has a running series where an external speaker is invited to give seminar talk during one of the usual meetings on their area of research or any topic of interest. The seminar then replaces the usual format of the meetings on those days. The list of external speakers will be updated as time goes on.
Tentative List of Seminars(*subject to change)
| Date | Speaker | Affiliation | Title of talk |
|---|---|---|---|
| Jun 11 | David Trestini | Southampton | Modeling gravitational waves from compact binaries in scalar tensor theories within the post-Newtonian approximation |

| Aug 6 | Rico Lo | NBI | TBA |
The next scheduled seminar speaker is Áron Kovács.
Title: Well-posed initial value formulation of general effective field theories of gravity
Abstract: In this talk, I will show that all higher-derivative effective field theories (EFTs) of vacuum gravity admit a well-posed initial value formulation when augmented by suitable regularising terms. These regularising terms can be obtained by field redefinitions and do not affect the dynamics in the regime of validity of EFT. I will explain how our result applies to the quadratic, cubic, and quartic truncations of the EFT of gravity and to various truncations of a simple EFT of a scalar field. Finally, I will also discuss some numerical results on the non-linear dynamics of this simple scalar field theory.

Note: Due to the current COVID-19 situation, the meetings have shifted to a hybrid format. This format will be followed until otherwise announced. In case one wishes to participate, please direct your queries to either Dr. Leo Stein <lcstein@olemiss.edu> or Dr. Anuradha Gupta <agupta1@olemiss.edu>.
