Flowing from the Ising Model on the Fuzzy Sphere to the 3D Lee-Yang CFT
Joan Elias Miro, Olivier Delouche
We employ the Fuzzy Sphere regulator to study the 3D Lee-Yang CFT. The model is defined by deforming the Ising model on the Fuzzy Sphere via a purely imaginary longitudinal magneti…

Testing the RG-flow with Hamiltonian Truncation
Olivier Delouche, Joan Elias Miro, James Ingoldby
Hamiltonian Truncation (HT) methods provide a powerful numerical approach for investigating strongly coupled QFTs. In this work, we develop HT techniques to analyse a specific Reno…

Hamiltonian Truncation Crafted for UV-divergent QFTs
Olivier Delouche, Joan Elias Miro, James Ingoldby
We develop the theory of Hamiltonian Truncation (HT) to systematically study RG flows that require the renormalization of coupling constants. This is a necessary step towards makin…
