Quantum steering for different types of Bell-like states in gravitational background
Physics Letters BIn a relativistic framework, it is generally accepted that quantum steering of maximally entangled states provides greater advantages in practical applications compared to non-maximally entangled states. In this paper, we investigate quantum steering for

Nuclear Physics BWe study a d-dimensional Anti-de Sitter (AdS) black hole surrounded by a static anisotropic quintessence field within the framework of Rastall theory. The solution is characterized by several parameters including its mass (M), field structure parameter ...

Black hole entropy, flat directions and higher derivatives
, 2009 Higher order derivative corrections to the Einstein--Maxwell action are considered and an explicit form is found for the corrections to the entropy of extremal black holes.

On the Universality of the Hawking Effect
, 2004 Addressing the question of whether the Hawking effect depends on degrees of freedom at ultra-high (e.g., Planckian) energies/momenta, we propose three rather general conditions on these degrees of freedom under which the Hawking effect is reproduced to ...

Attractors and first order formalism in five dimensions revisited
, 2010 The attractor mechanism in five dimensional Einstein-Maxwell Chern-Simons theory is studied. The expression of the five dimensional rotating black object potential depending on Taub-NUT, electric and magnetic charges as well as on all the scalar and ...

Effects of Lorentz symmetry breaking on quantum coherence in an expanding universe
Physics Letters BThis study investigates the interplay between Lorentz invariance violation (LIV) and quantum decoherence within an expanding universe. Motivated by quantum-gravity phenomenology, we incorporate a minimal length scale via spatial discretization, which ...

On the Particle Definition in the presence of Black Holes
, 2000 A canonical particle definition via the diagonalisation of the Hamiltonian for a quantum field theory in specific curved space-times is presented. Within the provided approach radial ingoing or outgoing Minkowski particles do not exist. An application of

Analogy of QCD hadronization and Hawking-Unruh radiation at NICA
, 2016 The proposed analogy of particle production from high-energy collisions and Hawking-Unruh radiation from black holes is extended to finite density (collisions) and finite-electric charge (black holes).

Remarks on four dimensional Euclidean gravity without Wick rotation
, 2006 In reference to S. W. Hawking's article "Information Loss in Black Holes" [S. W. Hawking, Phys. Rev. D 72 (2005) 084013], where a four dimensional Euclidean spacetime without Wick rotation is adopted for quantum gravity, an arithmetic with multiplicative
