Higher Order Quantum Corrections of Rotating BTZ Black Hole

In this work, we consider rotating BTZ black hole in three dimensions which is dual of one dimensional holographic superconductors. We applied higher order corrections of the entropy, which

Rotating Charged Hairy Black Hole in (2+1) Dimensions and Particle Acceleration

In this paper, we construct rotating charged hairy black hole in (2+1) dimensions for infinitesimal black hole charge and rotation parameters. Then we consider this black hole as particle accelerator

Corrected Entropy of BTZ Black Holes

In this paper, corrected entropy of a class of BTZ black holes, include charge and rotation, studied. We obtain corrected Bekenstein-Hawking entropy and find that effect of charge viewed at order

Thermodynamics of a Charged Hairy Black Holein (2+1) Dimensions

In this paper we study thermodynamics, statistics and spectroscopic aspects of a charged black hole with a scalar hair coupled to the gravity in (2+1) dimensions. We obtained effects of the black

Effects of higher-order corrected entropy on the black hole physics

In this paper we consider higher-order corrections of the BTZ and anti-de Sitter Schwarzschild black holes’ entropy and study corrected thermodynamics. We obtain some important thermodynamics

Gravitational Lensing of STU Black Holes

In this paper we study gravitational lensing by STU black holes. We considered extremal limit of two special cases of zero-charged and one-charged black holes, and obtain the deflection angle. We

THE CIRCULAR LOOP EQUATION OF A COSMIC STRING WITH TIME-VARYING TENSION

The equation of circular loops of cosmic string with time-dependent tension is studied in the Minkowski spacetime and Robertson–Walker universe. We found that, in the case where the tension depends

Cosmological evolution of cosmic strings with time-dependent tension

We discuss the cosmological evolution of cosmic strings with time-dependent tension. We show that, in the case that the tension changes as a power of time, the cosmic string network obeys the scaling

Primordial Black Holes and Cosmic String Loop

The elliptic loop equation of cosmic string is studied in the Minkowski space and during the radiation-dominated era in the Robertson-Walker universe. A remarkable fact about this equation is that a

We investigate cosmological evolution and implications of cosmic strings with time-dependent tension. We derive basic equations of time development of the correlation length and the velocity of such
