An Early Universe

An Early Universe offers a glimpse into the first moments after the Big Bang, recreating the extreme dynamics when waves and oscillations shaped the cosmos. The rippling water at the heart of the installation serves as an analogue for the early universe,

Early-Universe Model Building [PDF]

, 2022
Theoretical investigations into the evolution of the early universe are an essential part of particle physics that allow us to identify viable extensions to the Standard Model as well as motivated parameter space that can be probed by various experiments

Aether SUSY breaking: can aether be alternative to F-term SUSY breaking?

Journal of High Energy Physics, 2021
We investigate supersymmetry (SUSY) breaking scenarios where both SUSY and Lorentz symmetry are broken spontaneously. For concreteness, we propose models in which scalar fluid or vector condensation breaks Lorentz symmetry and accordingly SUSY.

New description of the scaling evolution of the cosmological magneto-hydrodynamic system

Physics Letters B, 2023
We present a new description of cosmological evolution of the primordial magnetic field under the condition that it is non-helical and its energy density is larger than the kinetic energy density.

Massive first star binaries as new tools for Galactic archaeology [PDF]

EPJ Web of Conferences, 2022
Binary systems are important probes of the origin of stars with peculiar chemical features through the interactions between two stars. We have studied the evolution of a metal-free massive binary after the collision of the supernova ejecta with a low ...

Implication of pulsar timing array experiments on cosmological gravitational wave detection

AAPPS Bulletin, 2021
Gravitational waves provide a new probe of the Universe which can reveal a number of cosmological and astrophysical phenomena that cannot be observed by electromagnetic waves.

The cosmic microwave background radiation power spectrum as a random bit generator for symmetric- and asymmetric-key cryptography

Heliyon, 2017
In this note, the Cosmic Microwave Background (CMB) Radiation is shown to be capable of functioning as a Random Bit Generator, and constitutes an effectively infinite supply of truly random one-time pad values of arbitrary length.

Precursors of Supernovae from Mass Eruption: Prospects for Early Warning of Nearby Core-collapse Supernovae

The Astrophysical Journal, 2023
Recent observations of a large fraction of Type II supernovae (SNe) show traces of dense circumstellar medium (CSM) very close to the progenitor star. If this CSM is created by eruptive mass loss several months before core collapse, the eruption itself ...

Horndeski model in nonlinearly realized supergravity

Journal of High Energy Physics, 2019
We construct the Horndeski Lagrangian within non-linearly realized super- gravity. We will show that the bosonic part of the Horndeski Lagrangian can be realized. Gravitino naturally couples to Horndeski sector in a super-covariant way.
