Generalized volume-complexity for Lovelock black holes

Autor: Emami, Monireh, Parvizi, Shahrokh

In this study, We explore the time dependence of the generalized complexity of Lovelock black holes via the "complexity = anything" conjecture, which expands upon the notion of "complexity = volume" and generates a large class of observables. By appl

On the values of commutativity degree of Lie algebras

Autor: Shamsaki, Afsaneh, Erfanian, Ahmad, Parvizi, Mohsen

In this paper, the possible values of commutativity degree of Lie algebras are determined. Also, we define the asymptotic commutativity degree of Lie algebras and obtain the asymptotic commutativity degree for some of them. Moreover, we prove the exi

Photon rings in the metamaterial analog of a gravitomagnetic monopole

Autor: Parvizi, A., Forghani-Ramandy, H., Rahmani, E., Nouri-Zonoz, M.

After studying null geodesics in the equatorial plane in NUT spacetime, we show that there are unstable photon rings in this plane. Next we transform the metric of this plane to the isotropic coordinates and introduce its equivalent index of refracti

The unification of quantum mechanics and general relativity has long been elusive. Only recently have empirical predictions of various possible theories of quantum gravity been put to test. The dawn of multi-messenger high-energy astrophysics has bee

Abstract Background Type-2 diabetes mellitus (T2DM) is considered one of the chronic diseases that can have a relationship with age of menopause onset. Several studies have revealed that early menopause or late menopause can have a correlation with t
