Hamiltonian Truncation Framework for Gauge Theories on the Interval
Rachel Houtz, James Ingoldby
In this work, we investigate gauge theories in two dimensions nonperturbatively using the Hamiltonian truncation approach. Working on a spatial interval and adopting the axial gaug…
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…
Effective Hamiltonians and Counterterms for Hamiltonian Truncation
Joan Elias Miro, James Ingoldby
We outline a procedure for applying Hamiltonian Truncation to Quantum Field Theories (QFTs) that have UV divergences. To do this, we derive a novel representation of an Effective H…
Hamiltonian Truncation with Larger Dimensions
Joan Elias Miro, James Ingoldby
Hamiltonian Truncation (HT) is a numerical approach for calculating observables in a Quantum Field Theory non-perturbatively. This approach can be applied to theories constructed b…
