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…
Gravitational Waves from Confining Dark Sectors with Self-Consistent Effective Potentials
Rachel Houtz, Martha Ulloa, Mia West
In this work, we present a self-consistent prediction for the gravitational wave signal arising from confinement-induced phase transitions in hidden non-Abelian SU(N) gauge theorie…
Fractional-charge hadrons and leptons to tell the Standard Model group apart
Rodrigo Alonso, Despoina Dimakou, Mia West
The gauge group of strong and electroweak interactions in Nature could be any of the four that share the same Lie algebra, with $…
Walls, bubbles and doom -- the cosmology of HEFT
Rodrigo Alonso, Juan Carlos Criado, Rachel Houtz +1
As experiment charts new territory at the electroweak scale, the enterprise to characterise all possible theories becomes all the more necessary. In the absence of new particles, t…
On the effective action for scalars in a general manifold to any loop order
Rodrigo Alonso, Mia West
Functional methods and a derivative expansion are employed for laying out a procedure to compute the effective action to any loop order, for scalar fields parametrising an arbitrar…
Using copies to improve precision in continuous-time quantum computing
Jemma Bennett, Adam Callison, Tom O'Leary +3
In the quantum optimisation setting, we build on a scheme introduced by Young et al [PRA 88, 062314, 2013], where physical qubits in multiple copies of a problem encoded into an Is…
On the road(s) to the Standard Model
Rodrigo Alonso, Mia West
Experimental measurements point at the Standard Model (SM) as the theory of electroweak symmetry breaking, but as we close in on our characterization the question arises of what li…
