We use ray-tracing techniques to determine the evolution of event horizon a large black hole that ``gobbles'' tiny, traversable wormhole. This calculation has physical meaning in extreme mass ratio limit. Two setups are considered: single-mouth wormhole connecting two otherwise independent universes, and double-mouth zero-length within same universe. In first setting it turns out that, at early times, there exist disconnected horizons, one each universe, which then merge as falls into hole....
We study the quantum backflow problem in noncommutative plane. In particular, we have considered a charged particle with and without an oscillator interaction noncommuting momentum operators examined angular each case how they differ from other. also propose probability associated occurence of investigate whether or not depends on physical parameter, namely magnetic field.
The merging of two black holes is a notoriously difficult process to describe exactly. Nevertheless, the hindrances posed by gravity's nonlinearity can be circumvented focusing on strict extreme mass ratio limit, in which one infinitely larger than other. Such an approach has been developed Emparan and Martínez applied within general relativity investigate time evolution event horizons melding, using nothing but elementary concepts gravitational physics simple integrations geodesics. We...

We study the quantum backflow problem of a relativistic charged Dirac fermion constrained to move on ring radius $R$. Using current operator we compute probability flux through generic time interval show emergence backflow. also discuss limiting case when particle moves along line.
