Efficient Hamiltonian Truncation: Fast Matrix Construction and Quantum Krylov Diagonalization
Rachel Houtz, Marco Knipfer, Konstantin Matchev +2
Hamiltonian truncation offers a nonperturbative route to quantum field theory, yet its accuracy is limited by the rapid expansion of the truncated Hilbert space, which drives up co…
Systematic derivation of perturbative unitarity bounds for any models
Nico Benincasa
In this letter, we provide a simple algorithm, anyPUB, to systematically derive the scattering matrix in the high-energy limit for any kind of models, irrespectiv…
Conformal versus non-conformal two-Higgs-doublet model: phase transitions and gravitational waves
Nico Benincasa, Ji-Wei Li, Hanxiao Pu +4
In this work we investigate the CP-conserving two-Higgs-doublet model (2HDM) in two realizations: a classically conformal setup (C2HDM) and a non-conformal setup with explicit tree…
Probing the Electroweak Phase Transition in the Dark Sector
Maimoona Razzaq, Nico Benincasa, Luigi Delle Rose +1
We study an extension of the Standard Model with a dark SU(2) gauge group, where a dark scalar doublet interacts with the Standard Model Higgs through a portal coupling, inducing m…
Phase transitions and gravitational waves in a non-abelian vector dark matter scenario
Nico Benincasa, Luigi Delle Rose, Luca Panizzi +2
We study a scenario where the Standard Model is extended by a SU(2) gauge group in the dark sector. The three associated dark gauge bosons are stabilised via a custodial symmetry t…
