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...
On a Recent Construction of "Vacuum-like" Quantum Field States in Curved Spacetime
"Vacuum-like" Quantum Field States Curved Spacetime Mathematical Physics
font style='font-size:12px;'>
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

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...
Nucleation of vacuum bubbles in Brans-Dicke type theory

2010/12/24
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 Einstein...
Entanglement dynamics of bipartite system in squeezed vacuum reservoirs

Entanglement plays a crucial role in quantum information protocols, thus the dynamical behavior of entangled states is of a great importance. In this paper we suggest a useful scheme that permits a di...
L.R.S. Bianchi type II Stiff Fluid cosmological model with Decaying Vacuum Energy Density $\Lambda$ in general relativity
LRS Bianchi type II models Cosmological constant

Locally rotationally symmetric (L.R.S.) Bianchi type II stiff fluid cos-mological model is investigated. To get the deterministic model of the universe, we have assumed a condition A = Bm between metr...
Electromagnetically superconducting phase of QCD vacuum induced by strong magnetic field
Quantum Chromodynamics Strong Magnetic Fields Superconductivity Rho Condensation
font style='font-size:12px;'>
2011/1/14
In this talk we discuss our recent suggestion that the QCD vacuum in a sufficiently strong magnetic field (stronger than 1016 Tesla) may undergo a spontaneous transition to an electromagnetically supe...

Properties of local Polyakov loops for SU(2) and SU(3) lattice gauge theory at finite temperature are analyzed. We show that spatial clusters can be identified where the local Polyakov loops have valu...
The quantum vacuum: an interpretation of quantum mechanics
The quantum vacuum interpretation quantum mechanics
font style='font-size:12px;'>
2010/11/8
We assume that particles are point-like objects even when not observed. We report on the consequences of our assumption within the realm of quantum theory. An important consequence is the necessity of...
