Quantum Anomalies Program Seminar: Ariel Zhitnitsky

Title: Maxwell Electrodynamics on 4 torus as a topologically ordered system Speaker:  Ariel Zhitnitsky Date: Monday, June 9, 2014 Time: 4:00pm-5:30pm Place: Seminar Room 313, Simons Center   [box, type=”download”]Watch the video.[/box] Abstract:I discuss a novel contribution to the Casimir vacuum energy which can not be expressed in terms of conventional propagating degrees of freedom. Instead, it is formulated in […]

Title: Casimir Effect: Diffraction and general boundary conditions Speaker:  Dimitra Karabali Date: Thursday, May 29, 2014 Time: 1:00pm-2:30pm Place: Seminar Room 313, Simons Center   [box, type=”download”]Watch the video.[/box] Abstract: Casimir effect refers to the emergence of macroscopic forces between neutral material bodies, such as conducting plates, in vacuum arising from the quantum fluctuations of fields. I will present a […]

Title: Stability of two-dimensional topological insulators Speaker:  Andrea Cappelli Date: Tuesday, May 27, 2014 Time: 1:00pm-2:30pm Place: Seminar Room 313, Simons Center   [box, type=”download”]Watch the video.[/box] Abstract: Topological insulators possess non-chiral edge excitations that can interact and decay. The criteria of stability in presence of time-reversal symmetry are reviewed and put in relation with the existence of discrete anomalies. […]

  Title: Critical phenomena in weakly dispersive nonlinear Hamiltonian PDEs and universality Speaker:  Boris Dubrovin (SISSA) Date: Thursday, May 15, 2014 Time: 1:00pm – 2:30pm Place: Seminar Room 313, Simons Center Abstract:  In the talk we will consider solutions to Hamiltonian perturbations of quasilinear PDEs with slow varying initial data. Our interest will be mainly focussed on the behaviour of solutions […]

  Title: A universal correction to higher spin entanglement entropy Speaker:  Justin David (Indian Institute of Science) Date: Tuesday, May 13, 2014 Time: 4:00pm – 5:30pm Place: Seminar Room 313, Simons Center Abstract: We consider conformal field theories in 1+1 dimensions with W-algebra symmetries, deformed by a chemical potential mu for the spin-three current. We show that the order mu^2 correction […]

Title: Exact Solutions to the Navier-Stokes Equations Speaker:  Oleg Bogoyavlenskij (Queen’s University, Kingston, Canada) Date: Monday, May 12, 2014 Time: 4:00pm – 5:30pm Place: Seminar Room 313, Simons Center Abstract:  A complete classication of all periodic solutions to the 3-dimensional Navier-Stokes equations with pairwise non-interacting Fourier modes is obtained. The corresponding sets of wave vectors k 2 Z3 necessarily belong either to the […]

Quantum Anomalies Program Seminar: Ian Affleck (UBC)

Title: Quantum impurity problems and conformal field theory Speaker:  Ian Affleck (UBC) Date: Tuesday, May 6, 2014 Time: 2:30pm – 3:30pm Place: Lecture Hall 102, Simons Center Abstract: Models of a single quantum impurity interacting with a gapless continuum of delocalized excitations play an important role in condensed matter physics. The universal low energy properties of such models can quite generally be […]
