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....
Simulation Vacuum Preloading Method by Tri-Axial Apparatus
Soft Soil Soil Improvement Vacuum Preloading Degree of Consolidation
2013/3/7
It is very important to control any risk of instability of embankment during vacuum construction, the simulation vacuum preloading method using tri-axial apparatus is proposed to predict the behavior ...
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 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...
Isotropic extensions of the vacuum solutions in general relativity
Isotropic extensions of the vacuum solutions in general relativity
2011/10/17
In this work we obtain isotropic extensions of the usual spherically symmetric vacuum geometries in general relativity. Exact and perturbative solutions are derived. The classes of geometries obtained...
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 ...

Relativistic Reduced-Mass and Recoil Corrections to Vacuum Polarization in Muonic Hydrogen, Muonic Deuterium and Muonic Helium Ions.
Safety of Minkowski Vacuum
Safety Minkowski Vacuum
2011/10/18
We give a simple argument suggesting that in a consistent quantum field theory tunneling from Minkowski to a lower energy vacuum must be impossible. Theories that allow for such a tunneling also allow...

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...
