Non-perturbative effects of laser illumination on the electrical properties of graphene nanoribbons
(IOP Publishing, 2013-03)
Floquet theory combined with a realistic description of the electronic structure of illuminated graphene and graphene nanoribbons is developed to assess the emergent non-adiabatic and non-perturbative effects on the ...
Adding flavour to the S-matrix bootstrap
(2018-12-01)
We explore the S-matrices of gapped, unitary, Lorentz invariant quantum field theories with a global O(N) symmetry in 1+1 dimensions. We extremize various cubic and quartic couplings in the two-to-two scattering amplitudes ...
The O(N) S-matrix monolith
(2020-04-01)
We consider the scattering matrices of massive quantum field theories with no bound states and a global O(N) symmetry in two spacetime dimensions. In particular we explore the space of two-to-two S-matrices of particles ...
Optimized δ expansion for the Walecka model

Light composite scalar boson from a see-saw mechanism in two-scale TC models
(2015-09-01)
We consider the possibility of a light composite scalar boson arising from mass mixing between a relatively light and heavy scalar singlets in a see-saw mechanism expected to occur in two-scale Technicolor (TC) models. A ...
