Pseudo entropy and topological phases of matter
Pramod Kamal Kharel, Manghang Limbu, Nabaraj Khatri +2
Entanglement entropy has proven to be a powerful probe of phenomena such as quantum chaos and phase transitions. Pseudo entropy is a recently proposed time-like generalization of a…

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…
