Holographic Reconstruction of Bubbles
Philipp Burda, Ruth Gregory, Akash Jain
We discuss the holographic reconstruction of static thin bubble walls in BTZ black hole geometries. We consider two reconstruction prescriptions suggested in recent years: hole-ogr…
The vacuum seagull: evaluating a 3-loop Feynman diagram with 3 mass scales
Philipp Burda, Barak Kol, Ruth Shir
We study a 3-loop 5-propagator Feynman Integral, which we call the vacuum seagull, with arbitrary masses and spacetime dimension using the Symmetries of Feynman Integrals method. I…
The Fate of the Higgs Vacuum
Ruth Gregory, Ian G. Moss
This talk reviews our recent work showing how tiny black holes can act as nucleation sites for the decay of the metastable Higgs vacuum. We start by discussing the formation of thi…
The fate of the Higgs vacuum
Philipp Burda, Ruth Gregory, Ian Moss
We have recently suggested that tiny black holes can act as nucleation seeds for the decay of the metastable Higgs vacuum. Previous results applied only to the nucleation of thin-w…
Vacuum metastability with black holes
Philipp Burda, Ruth Gregory, Ian Moss
We consider the possibility that small black holes can act as nucleation seeds for the decay of a metastable vacuum, focussing particularly on the Higgs potential. Using a thin-wal…
Gravity and the stability of the Higgs vacuum
Philipp Burda, Ruth Gregory, Ian Moss
We discuss the effect of gravitational interactions on the lifetime of the Higgs vacuum where generic quantum gravity corrections are taken into account. We show how small black ho…
Lifshitz flows in IIB and dual field theories
Philipp Burda, Ruth Gregory, Simon Ross
We construct solutions describing flows between AdS and Lifshitz spacetimes in IIB supergravity. We find that flows from AdS can approach either AdS or Lifshitz in the…
Solution of the Dyson--Schwinger equation on de Sitter background in IR limit
E. T. Akhmedov, Ph. Burda
We propose an ansatz which solves the Dyson-Schwinger equation for the real scalar fields in Poincare patch of de Sitter space in the IR limit. The Dyson-Schwinger equation for thi…
Casimir effect for massless minimally coupled scalar field between parallel plates in de Sitter spacetime
Philipp Burda
Casimir effect for massless minimally coupled scalar field is studied. An explicit answer for de Sitter spacetime is obtained and analized. Cosmological implications of the result…
A simple way to take into account back reaction on pair creation
Emil T. Akhmedov, Philipp Burda
We propose a simple and systematic way of accounting for the back reaction on the background field due to the pair creation in the four--dimensional scalar QED. This method is stra…
