Description
The 3d Ising CFT deformed by its Z2 odd sigma operator is one of the simplest examples in d>2 of a QFT built from a nontrivial UV fixed point. I will review the Fuzzy Sphere regulator approach to critical systems and describe results using the Fuzzy Sphere to obtain the spectrum of 3d Ising Field theory at finite and infinite volume, mainly focusing on the vacuum energy, lightest one-particle mass, the existence of a bound state in the spectrum, and dynamical consistency between sectors carrying different spin. I will also present comparisons with the system studied using the Truncated Conformal Space Approach.
