de Sitter Spacetime: Geometry, Causal Structure, and Quantum Fields
Azadeh Maleknejad, Ethan Richardson
de~Sitter spacetime plays a central role in modern cosmology, providing an excellent approximation to both inflation and the present accelerated expansion. It also offers a particu…
Stochastic Schwinger Effect: de Sitter and beyond
Lucas Vicente García-Consuegra, Azadeh Maleknejad
We develop a stochastic formulation of the Schwinger effect in de Sitter spacetime using the Schwinger--Keldysh (in-in) formalism, tailored to particle production by non-stationary…
Squashed Pyramid Interferometer Network (SPIN): Direct Access to Chirality of Cosmological Gravitational Waves
Dmitri E. Kharzeev, Azadeh Maleknejad, Saba Shalamberidze
The cosmological gravitational wave background provides a powerful window on parity-violating physics at energies far beyond the reach of terrestrial experiments. However, any colo…
