A (3 + 1)-dimensional asymptotically flat Kerr black hole angular speed Omega(+) can be used to define an effective spring constant, k = m Omega(2)(+). Its maximum value is the Schwarzschild surface gravity, k = kappa, which rapidly weakens as the black hole spins down and the temperature increases. The Hawking temperature is expressed in terms of the spring constant: 2 pi T = kappa - k. Hooke's law, in the extremal limit, provides the force F = 1/4, which is consistent with the conjecture of…

Accelerating boundary analog of a Kerr black hole
An accelerated boundary correspondence (i.e. a flat spacetime accelerating mirror trajectory) is derived for the Kerr spacetime, with a general formula that ranges from the Schwarzschild limit (zero
Quantum atmosphere of Reissner-Nordström black holes
Hawking radiation originates from a "quantum atmosphere" around black holes, not necessarily from the vicinity of the horizon. We examine and discuss the properties of quantum atmospheres of

Particle spectrum of the Reissner–Nordström black hole
The Reissner-Nordstrom black hole - moving mirror correspondence is solved. The beta coefficients reveal that charge makes a black hole radiate fewer particles (neutral massless scalars) per

Black hole Hookean law and thermodynamic fragmentation: Insights from the maximum force conjecture and Ruppeiner geometry
We show that the notion of “Hookean law” F = kx , suitably defined in asymptotically flat singly spinning Myers-Perry black hole spacetimes in dimensions d (cid:62) 5, is related to the Emparan-Myers
Observers in Kerr spacetimes: the ergoregion on the equatorial plane
We perform a detailed analysis of the properties of stationary observers located on the equatorial plane of the ergosphere in a Kerr spacetime, including light-surfaces. This study highlights crucial
Applications of Gravitational Model of Possible Final Unification in both Large & Small Scale Physics
Considering two pseudo gravitational constants assumed to be connected with proton and electron, we make an attempt to fit the Newtonian gravitational constant. In this semi- empirical approach,
A modification to the mirror trajectory corresponding to shell collapse
The well-known moving mirror trajectory corresponding to black hole shell collapse scenario (BHC) appears to produce an infinite amount of energy. By changing the final velocity of the BHC mirror

The String landscape, black holes and gravity as the weakest force
We conjecture a general upper bound on the strength of gravity relative to gauge forces in quantum gravity. This implies, in particular, that in a four-dimensional theory with gravity and a U(1)

The Einstein equations with a negative cosmological constant admit black hole solutions which are asymptotic to anti-de Sitter space. Like black holes in asymptotically flat space, these solutions

We show that AdS black holes dual to field theories on flat spacetime, as used in applications of the AdS/CFT correspondence to strong interaction and condensed matter physics, have temperatures with
Thermodynamic phase transitions of Kerr-Newman black holes in de Sitter space
A curious feature of black holes which rotate and/or carry electric charge is that as the rotation and/or charge is increased the black hole undergoes a second-order phase transition in which its

We show that axisymmetric extremal horizons are unstable under linear scalar perturbations. Specifically, we show that translation invariant derivatives of generic solutions to the wave equation do
Particle Creation by Black Holes
. In the classical theory black holes can only absorb and not emit particles. However it is shown that quantum mechanical effects cause black holes to create and emit particles as if they were hot
