Towards a Proof of the Improved Quantum Null Energy Condition
Ido Ben-Dayan, Ayushi Srivastava
The Improved Quantum Null Energy Condition (INEC) was recently derived from the (restricted) quantum focusing conjecture (QFC), and is a statement about the energy-momentum tensor…

Islands in Bianchi type-I Universe
Ido Ben-Dayan, Merav Hadad, Ayushi Srivastava
We study the conditions for finding an island in an anisotropic universe - Bianchi Type-I filled with radiation. We verify that the existence of islands does not depend on their sh…
