Can a false vacuum bubble remove the singularity inside a black hole?

European Physical Journal C: Particles and Fields, 2020
We investigate a regular black hole model with a de Sitter-like core at its center. This type of a black hole model with a false vacuum core was introduced with the hope of singularity-resolution and is a common feature shared by many regular black holes.

First order phase transition with a logarithmic singularity in a model with absorbing states

, 2000
Recently, Lipowski [cond-mat/0002378] investigated a stochastic lattice model which exhibits a discontinuous transition from an active phase into infinitely many absorbing states.

Berry's Phase for Standing Wave Near Graphene Edge

, 2010
Standing waves near the zigzag and armchair edges, and their Berry's phases are investigated. It is suggested that the Berry's phase for the standing wave near the zigzag edge is trivial, while that near the armchair edge is non-trivial.

Asymptotic safety in the sine-Gordon model [PDF]

, 2014
In the framework of the functional renormalization group method it is shown that the phase structure of the 2-dimensional sine-Gordon model possesses a nontrivial UV fixed point which makes the model asymptotically safe.

Spin angular momentum density in the tight focus of a light field with phase and polarization singularities [PDF]

Компьютерная оптика, 2019
For a light field with both phase and polarization singularities at its center, expressions are obtained that describe the distribution of the spin angular momentum (SAM) density in the sharp focal spot of an aplanatic system.

Rare region effects at classical, quantum, and non-equilibrium phase transitions

, 2006
Rare regions, i.e., rare large spatial disorder fluctuations, can dramatically change the properties of a phase transition in a quenched disordered system.

Cosmology With Negative Potentials [PDF]

, 2002
We investigate cosmological evolution in models where the effective potential V(\phi) may become negative for some values of the field \phi. Phase portraits of such theories in space of variables (\phi,\dot\phi,H) have several qualitatively new features ...

The zonal satellite problem - II: Near-escape flow [PDF]

Serbian Astronomical Journal, 1998
The study of the zonal satellite problem is continued by tackling the situation r→∞. New equations of motion (for which the infinite distance is a singularity) and the corresponding first integrals of energy and angular momentum are set up.

Influence of Long-Range Coulomb Interactions on the Metal-Insulator Transition in One-Dimensional Strongly Correlated Electron Systems

, 1994
The influence of long-range Coulomb interactions on the properties of one-dimensional (1D) strongly correlated electron systems in vicinity of the metal-insulator phase transition is considered.
