Heterotic Warm Inflation

Arjun Berera, Heliudson Bernardo, Suddhasattwa Brahma +3

We propose a two-field model of warm inflation motivated by a heterotic string construction, involving an axion and a dilaton-like scalar field with non-trivial kinetic mixing. Gau…

Thermal enhancement of inflationary magnetic fields

Arjun Berera, Suddhasattwa Brahma, Zizang Qiu +1

We investigate primordial magnetogenesis by assuming the gauge field is prepared in a thermal state during inflation rather than the standard Bunch-Davies vacuum. The temperature $…

Choice of Quantum Vacuum for Inflation Observables

Melo Wood-Saanaoui, Rudnei O. Ramos, Arjun Berera

We investigate the modifications to inflationary observables that arise when adopting an -vacuum instead of the standard Bunch--Davies vacuum for quantum fluctuations during in…

Measuring the effect of spatial dimension on hydrodynamic turbulence using direct numerical simulation

Richard D. J. G. Ho, Daniel Clark, Andres Armua +3

We perform direct numerical simulation of the incompressible Navier-Stokes equation with forcing at different spatial dimensions and measure turbulent and chaotic properties. Lyapu…

The early universe is -ing

Arjun Berera, Suddhasattwa Brahma, Zizang Qiu +2

The recently released data from the (ACT) confirms that the primordial scalar spectrum is extremely flat. This, together with current upper b…

Measuring Coherent Radio and Microwave Photons from the Solar Corona

Liang Chen, Zizang Qiu, Thomas W. Kephart +1

The rates of production of radio/microwave N-identical photons states |N> from stimulated emission in the solar atmosphere are estimated. Effects of various decohering factors are…
