Nonperturbative Bounds on Scattering of Massive Scalar Particles in
Hongbin Chen, A. Liam Fitzpatrick, Denis Karateev
We study two-to-two scattering amplitudes of a scalar particle of mass . For simplicity, we assume the presence of symmetry and that the particle is $\mathbb{Z}_2…

Giving Hamiltonian Truncation a Boost
Hongbin Chen, A. Liam Fitzpatrick, Emanuel Katz +1
We study Hamiltonian truncation in boosted frames. We consider the thermal and magnetic field deformations of the 2d Ising model using TCSA at finite momentum. We find that even wi…
