| Title: | Quantum Spectral Curve (QSC) for bi-scalar fishnet theory |
| Date (JST): | Tue, Apr 17, 2018, 13:15 - 14:30 |
| Place: | Seminar Room A |
| Abstract: |
Starting with a review of the Quantum Spectral Curve (QSC) formalism - which is conjectured to capture the spectrum of arbitrary single-trace operators in planar N=4 SYM - we will discuss how it can be adapted to capture deformations of N=4. For the main part of the talk we will focus on a particular deformation in a double-scaling limit, combining weak coupling and strong imaginary twist, resulting in a simple bi-scalar theory in four dimensions. This non-unitary theory turns out to be conformal, and is dominated by integrable fishnet Feynman graphs. We will give an adequate QSC description of this model, and discuss some recently obtained results for higher twist operators. |
