Regular Seminar Anatoly Konechny (Heriot-Watt)
at: 14:00 - 14:01 KCL Strand room: S0.12 abstract: | We will consider perturbations of 2D CFTs by multiple relevant operators. The massive phases of such perturbations can be labeled by conformal boundary conditions. Cardy's variational ansatz approximates the vacuum state of the perturbed theory by a smeared conformal boundary state. In this talk we will discuss the limitations and propose generalisations of this ansatz using both analytic and numerical insights based on TCSA.
