Enlarging the symmetry of pure gravity, BRST invariance and its spontaneous breaking
Ariel Edery
Pure gravity was considered originally to possess only global scale symmetry. It was later shown to have the larger restricted Weyl symmetry where it is invariant under the W…
The non-minimally coupled gravitating vortex: phase transition at critical coupling in AdS
Ariel Edery
We consider the Nielsen-Olesen vortex non-minimally coupled to Einstein gravity with cosmological constant . A non-minimal coupling term is natural to add to the v…
Wave packets in QFT: leading order width corrections to decay rates and clock behaviour under Lorentz boosts
Ariel Edery
Decay rates in quantum field theory (QFT) are typically calculated assuming the particles are represented by momentum eigenstates (i.e. plane waves). However, strictly speaking, lo…
Non-singular vortices with positive mass in 2+1 dimensional Einstein gravity with AdS and Minkowski background
Ariel Edery
In previous work, black hole vortex solutions in Einstein gravity with AdS background were found where the scalar matter profile had a singularity at the origin . In this…
Critical gravity from four dimensional scale invariant gravity
Ariel Edery, Yu Nakayama
We show that a critical condition exists in four dimensional scale invariant gravity given by the pure quadratic action where is the…
Palatini formulation of pure gravity yields Einstein gravity with no massless scalar
Ariel Edery, Yu Nakayama
Pure gravity has been shown to be equivalent to Einstein gravity with non-zero cosmological constant and a massless scalar field. We show that the Palatini formulation of pur…
Gravitating magnetic monopole via the spontaneous symmetry breaking of pure gravity
Ariel Edery, Yu Nakayama
The pure gravity is equivalent to Einstein gravity with cosmological constant and a massless scalar field and it further possesses the so-called restricted Weyl symmetry whic…
Generating Einstein gravity, cosmological constant and Higgs mass from restricted Weyl invariance
Ariel Edery, Yu Nakayama
Recently, it has been pointed out that dimensionless actions in four dimensional curved spacetime possess a symmetry which goes beyond scale invariance but is smaller than full Wey…
Restricted Weyl invariance in four-dimensional curved spacetime
Ariel Edery, Yu Nakayama
We discuss the physics of {\it restricted Weyl invariance}, a symmetry of dimensionless actions in four dimensional curved space time. When we study a scalar field nonminimally cou…
Radiatively induced symmetry breaking and the conformally coupled magnetic monopole in AdS space
Ariel Edery, Noah Graham
We implement quantum corrections for a magnetic monopole in a classically conformally invariant theory containing gravity. This yields the trace (conformal) anomaly and introduces…
Directly observing entropy accumulate on the horizon and holography
Ariel Edery, Hugues Beauchesne
Recent numerical simulations of gravitational collapse show that there exists a special foliation of the spacetime where matter and entropy accumulate directly on the inside of the…
3D scalar model as a 4D perfect conductor limit: dimensional reduction and variational boundary conditions
A. Edery, N. Graham, I. MacDonald
Under dimensional reduction, a system in D spacetime dimensions will not necessarily yield its D-1-dimensional analog version. Among other things, this result will depend on the bo…
Compact dimensions and the Casimir effect: the Proca connection
Ariel Edery, Valery Marachevsky
We study the Casimir effect in the presence of an extra dimension compactified on a circle of radius R ( spacetime). Our starting point is the Kaluza Klein decomposi…
The perfect magnetic conductor (PMC) Casimir piston in d+1 dimensions
A. Edery, V. Marachevsky
Perfect magnetic conductor (PMC) boundary conditions are dual to the more familiar perfect electric conductor (PEC) conditions and can be viewed as the electromagnetic analog of th…
Cancellation of nonrenormalizable hypersurface divergences and the d-dimensional Casimir piston
Ariel Edery, Ilana MacDonald
Using a multidimensional cut-off technique, we obtain expressions for the cut-off dependent part of the vacuum energy for parallelepiped geometries in any spatial dimension d. The…
Casimir piston for massless scalar fields in three dimensions
Ariel Edery
We study the Casimir piston for massless scalar fields obeying Dirichlet boundary conditions in a three dimensional cavity with sides of arbitrary lengths and where i…
Spontaneous breaking of conformal invariance in theories of conformally coupled matter and Weyl gravity
A. Edery, Luca Fabbri, M. B. Paranjape
We study the theory of Weyl conformal gravity with matter degrees of freedom in a conformally invariant interaction. Specifically, we consider a triplet of scalar fields and SO(3)…
Casimir forces in Bose-Einstein condensates: finite size effects in three-dimensional rectangular cavities
Ariel Edery
The Casimir force due to {\it thermal} fluctuations (or pseudo-Casimir force) was previously calculated for the perfect Bose gas in the slab geometry for various boundary condition…
