Generation and search of axion-like light particle using intense crystalline field
Generation search of axion-like light particle intense crystalline field
2011/1/6
Intense electric field 1010− 1011 V/cm in crystal has been known for a long time and has wide applications.
Multifunctional oxides are promising materials because of their fundamental physical properties as well as their potential in applications1. Among these materials,multiferroics exhibiting ferroelectri...
We present a lattice study of up to N = 20 unitary fermions confined to a harmonic trap. Our
preliminary results show better than 1% agreement with high precision solutions to the many-body Schroding...
On the Interaction in Lattice Gauge Theory
Interaction picture Haag`s theorem Space-time lattice
2011/1/14
Haag`s theorem states that if a quantum field theory is Lorentz invariant and irreducible, there is no interaction picture.
Influence of itinerancy on the magnetic properties of the single crystals of Sr2YRu1-xCuxO6 solid solutions

2010/11/23
X-ray absorption spectroscopy(XAS) Ru L-edge and O K-edge measurements on single crystals of Sr2YRu1-xCuxO6 (x=0.01-0.05) solid solutions show that Cu replaces Ru in the lattice which results in a lat...
Valence-bond crystal in the extended Kagomé spin-1/2 quantum Heisenberg antiferromagnet: A variational Monte Carlo approach

Graphene has attracted enormous attention due to its numerous remarkable properties and wide range of potential applications. To fully realize its potential, graphene needs to be synthesized in large ...
Self-glassiness in binary mixtures: the compacton picture
Self-glassiness compacton picture
2010/11/18
We present a new phase-field model for binary fluids exhibiting typical signatures of self-glassiness,such as long-time relaxation, ageing and long-term dynamical arrest. The present model allows the ...

2010/11/23
Using a single functional form which is able to represent several different classes of
statistical distributions, we introduce a preliminary study of the ferromagnetic Ising model
on the cubic latti...

2010/10/21
We show that stochastic phase-space methods within the truncated Wigner approximation can be used to solve non-equilibrium dynamics of bosonic atoms in 1d traps. We consider systems both with and with...
We present a general criterion for entanglement of N indistinguishable particles decomposed into arbitrary s subsystems based on the unambiguous measurability of correlation. Our argument provides a u...
