On behalf of the Organizing Committee, it is my great honor and pleasure to invite you to the 20th International Vacuum Congress (IVC-20), which will be held in Busan, Korea from August 21 to 26, 2016...
A Fully Anisotropic Mechanism for Formation of Trapped Surfaces in Vacuum
A Fully Anisotropic Mechanis Trapped Surfaces Vacuum
2014/4/3
In collaboration with I. Rodnianski and J. Luk we extend considerably the result of Christodoulou on the dynamic formation of trapped surfaces in vacuum by allowing characteristic initial data which a...
On a Recent Construction of "Vacuum-like" Quantum Field States in Curved Spacetime
"Vacuum-like" Quantum Field States Curved Spacetime Mathematical Physics
2012/6/29
Afshordi, Aslanbeigi and Sorkin have recently proposed a construction of a distinguished "S-J state" for scalar field theory in (bounded regions of) general curved spacetimes. We establish rigorously ...
Quantum Ground States as Equilibrium Particle-Vacuum Interaction States
Quantum ground states Vacuum fluctuations Particle‐vacuum interaction states Zero‐point fluctuations Harmonic oscillator quantum ground state
2012/4/20
A remarkable feature of atomic ground states is that they are observed to be radiationless in nature, despite (from a classical viewpoint) typically involving charged particles in accelerated motions....
Advanced Space Propulsion Based on Vacuum (Spacetime Metric) Engineering
Space propulsion metric engineering spacetime alteration warp drives wormholes polarizable vacuum
2012/4/20
A theme that has come to the fore in advanced planning for long-range space exploration is the concept that empty space itself (the quantum vacuum, or spacetime metric) might be engineered so as to pr...
Global Classical and Weak Solutions to the Three-Dimensional Full Compressible Navier-Stokes System with Vacuum and Large Oscillations
Global Classical Weak Solutions Three-Dimensional Full Compressible Navier-Stokes System Vacuum and Large Oscillations
2011/9/19
Abstract: We establish the global existence and uniqueness of classical solutions to the three-dimensional full compressible Navier-Stokes system with smooth initial data which are of small energy but...
Physical vacuum as a system manifesting itself on various scales - from nuclear physics to cosmology
Physical vacuum system various scales nuclear physics cosmology
2011/8/3
Abstract: Suggested here is an attempt to resolve on a phenomenological basis the most keenly discussed enigma of the Universe, namely, the essence of its base medium, "dark energy", which is usually ...

Local extendability of Einstein vacuum manifolds
Einstein vacuum manifolds Mathematical Physics
2011/8/24
Abstract: We focus in this article on local extendability properties of Einstein vacuum spacetimes. We prove in particular a geometric breakdown criterion localized in space and time in a transversal ...
We propose a quantum model for the vacuum filled of virtual particle pairs. The main originality of this model is to define a density and a life-time of the virtual particles. Compared to the usual QE...
Is the Schwarzschild Metric a Vacuum Solution of the Einstein Equation?
the Schwarzschild Metric Vacuum Solution the Einstein Equation
2011/9/13
This paper examines the inhomogeneous Einstein equation for a static spherically symmetric metric with a source term corresponding to perfect fluid with p = −. By a careful treatment of the equ...
On a proof of the collapse conjecture for a diagonal Bianchi type-IX vacuum space-time
collapse conjecture diagonal Bianchi type-IX vacuum space-time General Relativity and Quantum Cosmology
2011/7/27
Abstract: It is given a simple proof of the collapse conjecture for a diagonal Bianchi type-IX vacuum space-time. It is shown that the codimension of the infinity stable attractor, restricted to the a...
Is dark matter an illusion created by the gravitational polarization of the quantum vacuum?
dark matter the quantum vacuum the gravitational polarization
2011/8/29
Assuming that a particle and its antiparticle have the gravitational charge of the opposite sign, the physical vacuum may be considered as a fluid of virtual gravitational dipoles. Following this hypo...

In this paper, we study nucleation of vacuum bubbles in the Brans-Dicke type theory of
gravity. In the Euclidean signatures, we calculate field combinations of vacuum bubbles as
solutions of Einstei...
