Group Seminar
Coming to give a seminar at SISSA? Please refer to our speaker's page.
The 'Group Seminar' is a regular appointment of the Theoretical Particle Physics group. It usually takes place on Wednesday at 4pm in room 005 (ground floor) or in the Lecture Hall 137 (first floor). The seminars typically last for 50 minutes leaving time for questions and discussion.
You can find the list of seminars scheduled in the week in the calendar and the complete list of seminar in the Group Seminar history.

Monopoles, duality, and QED3 |
| We consider quantum electrodynamics in 2+1 dimensions (QED3) with N matter fields and Chern-Simons level k. For small values of k and N, this theory describes various experimentally relevant systems in condensed matter, and is also conjectured to be part of a web of non-supersymmetric dualities. We compute the scaling dimensions of monopole operators in a large N and k expansion, which appears to be extremely accurate even down to the smallest values of N and k, and allows us to find dynamical evidence for these dualities and make predictions about the phase transitions. For instance, we combine these estimates with the conformal bootstrap to predict that the notorious Neel-VBS transition (QED3 with 2 scalars) is tricritical, which was recently confirmed by independent lattice simulations. Lastly, we propose a novel phase diagram for QED3 with 2 fermions, including duality with the O(4) Wilson-Fisher fixed point. | |
