Cosmological Pseudo-Entropy
Manghang Limbu, Pramod Kamal Kharel, Rohit Bhattarai +1
We study pseudo entropy , a recent generalization of entanglement entropy, for scalar cosmological perturbations in de Sitter space with sound speed $0.024 \leq c_s \l…
Entanglement and particle production from cosmological perturbations: a quantum optical simulation approach
Pramod Kamal Kharel, Mausam Ghimire, Ashish Khanal +6
In this work, we develop a computational framework based on the Gaussian formalism and symplectic circuit representation to explore cosmological perturbations during inflation. The…
Out of the box approach to Black hole Information paradox
Kiran Adhikari
Suppose a black hole forms from a pure quantum state . The black hole information loss paradox arises from semiclassical arguments suggesting that, even in a closed system,…
Primordial Gravitational Wave Circuit Complexity
Kiran Adhikari, Sayantan Choudhury, Hardey N. Pandya +1
In this article, we investigate various physical implications of quantum circuit complexity using squeezed state formalism of Primordial Gravitational Waves (PGW). Recently quantum…
