This paper discusses particle production in Schwarzschild-like spacetimes and in a uniform electric field. Both problems are approached using the method of complex path analysis which is used to describe tunnelling processes in semiclassical quantum mechanics. Particle production in Schwarzschild-like spacetimes with a horizon is obtained here by a new and simple semiclassical method based on the method of complex paths. Hawking radiation is obtained in the $(t,r)$ coordinate system of the…

Quantum Tunnelling for Hawking Radiation from Both Static and Dynamic Black Holes

The paper deals with Hawking radiation from both a general static black hole and a nonstatic spherically symmetric black hole. In case of static black hole, tunnelling of nonzero mass particles is

Corrections to Unruh effect in tunneling formalism and mapping with Hawking effect

We consider coordinate systems adapted to accelerated observers, construct a generalised Rindler metric and then adopt a specific form of it to compute the semiclassical Unruh temperature, using a

Temperature and thermodynamic structure of Einstein's equations for a cosmological black hole

It is expected that the cosmological black holes are the closest realistic solutions of gravitational theories and they evolve with time. Moreover, the natural way of defining thermodynamic entities

A novel approach to particle production in an uniform electric field

We outline a different method of describing scalar field particle production in a uniform electric field. In the standard approach, the (analytically continued) harmonic oscillator paradigm is

Radiation from Einstein–Gauss–Bonnet de Sitter black hole via tunneling process

In this paper, we probe in 4D Einstein–Gauss–Bonnet black hole and its thermodynamics. We illustrate the three asymptotically 4D EGB spacetime as an asymptotically flat, de Sitter, and Anti-de

Thermality of horizon through near horizon instability: a path integral approach

Recent investigations revealed that the near horizon Hamiltonian of a massless, chargeless outgoing particle, for its particular motion in static as well as stationary black holes, is effectively ∼ xp

Cosmological and black hole Islands in multi-event horizon spacetimes

In this paper, we have analysed the information paradox and its resolution using island proposal in Schwarzschild de-Sitter black hole spacetime. First, we study the information paradox for the black

Artificial Hawking black hole radiation using feedback-based mechanical circuits

Black holes are considered among the most fascinating objects that exist in our universe, since in the classical formalism nothing, even no light, can escape from their vicinity. However, Hawking

Stationary and Free-fall frame Kerr black hole in gravity's rainbow

Doubly special relativity (DSR) is an effective model for encoding quantum gravity in flat spacetime. To incorporate DSR into general relativity, one could use “gravity’s rainbow,” where the spacetime
