A bstract We consider the transfer of a U(1) charge density between Bose-Einstein condensates complex scalar fields coupled to thermal bath, focusing on case homogeneous Affleck-Dine field transmitting stored in its angular motion an axion field. demonstrate that absence additional symmetries this transfer, aided by cosmic expansion as well effective potential field, can be very efficient. The ...

A bstract Conformal Carroll symmetry generically arises on null manifolds and is important for holography of asymptotically flat spacetimes, generic black hole horizons tensionless strings. In this paper, we focus two dimensional (2 d ) hence the 2 or equivalently 3 Bondi-Metzner-Sachs (BMS) algebra. Using covariance, write most general free massless scalar field theory discover three inequival...

We revisit inflation with non-canonical scalar fields by applying deformed-steepness exponential potentials. show that the resulting scenario can lead to inflationary observables, and in particular spectral index tensor-to-scalar ratio, remarkable agreement observations. Additionally, a significant advantage of is required parameter values, such as non-canonicality exponent scale, well potentia...
