Dynamical black-hole scenarios have been developed in loop quantum gravity in various
ways, combining results from mini and midisuperspace models. In the past, the underlying …

Loop Quantum Gravity is a nonperturbative and background independent program for the
quantization of General Relativity. Its underlying formalism has been applied successfully to …

Optical metamaterials have redefined how we understand light in notable ways: from strong
response to optical magnetic fields, negative refraction, fast and slow light propagation in …

This chapter provides a review of the frameworks developed for cosmological perturbation
theory in loop quantum cosmology and applications to various models of the early universe …

We present results from a numerical study of spherical gravitational collapse in shift
symmetric Einstein dilaton Gauss–Bonnet (EdGB) gravity. This modified gravity theory has a …

For the construction of the Lorentzian path integral for gravity one faces two main questions:
firstly, what configurations to include, in particular whether to allow Lorentzian metrics that …

We investigate the interior structure, perturbations, and the associated quasinormal modes
of a quantum black hole model recently proposed by Bodendorfer, Mele, and Münch (BMM) …

A large number of models have been analyzed in loop quantum cosmology, using mainly
minisuperspace constructions and perturbations. At the same time, general physics …

Transformation optics asks, using Maxwell's equations, what kind of electromagnetic
medium recreates some smooth deformation of space? The guiding principle is Einstein's …

Spherically symmetric models of loop quantum gravity have been studied recently by
different methods that aim to deal with structure functions in the usual constraint algebra of …
