Weyl invariant theories of scalars and gravity can generate all mass scales spontaneously,
initiated by a dynamical process of “inertial spontaneous symmetry breaking” that does not …

A scale-invariant universe can have a period of accelerated expansion at early times:
inflation. We use a frame-invariant approach to calculate inflationary observables in a scale …

We review the approach to the Standard Model of particle interactions based on spectral
noncommutative geometry. The paper is (nearly) self-contained and presents both the …

Scale invariant theories of gravity give a compelling explanation to the early and late time
acceleration of the Universe. Unlike most scalar-tensor theories, fifth forces are absent, and …

We review the noncommutative approach to the standard model. We start with the
introduction if the mathematical concepts necessary for the definition of noncommutative …

We show that a massless scalar field in a gravitational wave background can develop a non-
zero vacuum expectation value. We draw comparisons to the generation of a non-zero …

Given that gravitational waves are the future probes of the Universe, it is important to test
various physical effects of these on matter. This article explores the first-order perturbation …

We consider implications of the microscopic dynamics of spacetime for the evolution of
cosmological models. We argue that quantum geometry effects may lead to stochastic …

In this paper, we consider a quantum mechanical system to model the effect of quantum
fields on the evolution of the early universe. The system consists of an inverted oscillator …

We study baryogenesis in effective field theories where a U (1) BL-charged scalar couples to
gravity via curvature invariants. We analyze the general possibilities in such models, noting …
