Higher order clockwork gravity (2018)
Journal Article

We present a higher order generalisation of the clockwork mechanism starting from an underlying non-linear multigravity theory with a single scale and nearest neighbour ghost-free interactions. Without introducing any hierarchies in the underlying po... Read More about Higher order clockwork gravity.

Boltzmann equations for preheating (2018)
Journal Article

We derive quantum Boltzmann equations for preheating by means of the density matrix formalism, which account for both the non-adiabatic particle production and the leading collisional processes between the produced particles. In so doing, we illustra... Read More about Boltzmann equations for preheating.

Rotating kinky braneworlds (2018)
Journal Article

Cylindrical braneworlds have been used in the literature as a convenient way to resolve co-dimension-two branes. They are prevented from collapsing by a massless worldvolume field with non-trivial winding, but here we discuss another way of preventin... Read More about Rotating kinky braneworlds.

Simulations of cold electroweak baryogenesis: dependence on the source of CP-violation (2018)
Journal Article

We compute the baryon asymmetry created in a tachyonic electroweak symmetry breaking transition, focusing on the dependence on the source of effective CP-violation. Earlier simulations of Cold Electroweak Baryogenesis have almost exclusively consider... Read More about Simulations of cold electroweak baryogenesis: dependence on the source of CP-violation.

Simulations of Cold Electroweak Baryogenesis: quench from portal coupling to new singlet field (2018)
Journal Article

We compute the baryon asymmetry generated from Cold Electroweak Baryogenesis, when a dynamical Beyond-the-Standard-Model scalar singlet field triggers the spinodal transition. Using a simple potential for this additional field, we match the speed of... Read More about Simulations of Cold Electroweak Baryogenesis: quench from portal coupling to new singlet field.
