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…
SYK Model in a Non-Gaussian disorder ensemble and emergent Coleman's mechanism
Ido Ben-Dayan, Pankaj Chaturvedi
We consider the case of the SYK model with non-gaussian disorder in the large limit. After obtaining the effective action, we derive the density of states and the free energy o…
The Quantum Focusing Conjecture and the Improved Energy Condition
Ido Ben-Dayan
By rearranging its terms, the Quantum Focusing Conjecture (QFC) can be viewed as a quantum energy condition, and we can consider various limits. A recent restricted version is a li…
Islands in the Fluid: Islands are Common in Cosmology
Ido Ben-Dayan, Merav Hadad, Elizabeth Wildenhain
We discuss the possibility of entanglement islands in cosmological spacetimes with a general perfect fluid with an equation of state . We find that flat universes with time-symm…
The Grand Canonical Multiverse and the Small Cosmological Constant
Ido Ben-Dayan, Merav Hadad, Amir Michaelis
We consider the Multiverse as an ensemble of universes. Using standard statistical physics analysis we get that the Cosmological Constant (CC) is exponentially small. The small and…
