We present a general framework to study relativistic compound systems in a Hamiltonian formalism. This formalism is based on the explicitly covariant formulation of light-front dynamics, with a decomp...
Symmetric Criticality in Classical Field Theory
Symmetric Criticality Classical Field Theory
2010/12/21
This is a brief overview of work done by Ian Anderson, Mark Fels, and myself on symmetry reduction of Lagrangians and Euler-Lagrange equations, a subject closely related to Palais’ Principle of Symmet...
A new microscopic nucleon-nucleon interaction derived from relativistic mean field theory
new microscopic nucleon-nucleon interaction derived relativistic mean field theory
2011/1/7
A new microscopic nucleon-nucleon (NN) interaction has been derived for the first time from
the popular relativistic mean field theory (RMFT) Lagrangian. The NN interaction so obtained
remarkably re...
Spontaneous imbibition in a slit pore: a lattice-gas dynamic mean field study
Spontaneous imbibition slit pore lattice-gas dynamic mean field study
2010/11/22
We present a theoretical study of spontaneous imbibition in a slit pore using a lattice-gas model and a dynamic mean- eld theory. Emphasis is put on the in uence of the precursor lms on the speed of ...
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...
Effective Field Theory and High-Precision Calculations of Nuclear Electroweak Processes
Effective Field Theory High-Precision Calculations of Nuclear Electroweak Processes
2011/1/7
High-precision calculations of electroweak processes in light nuclei are of great importance
for multiple reasons. Gerry Brown together with Dan-Olof Riska published in 1972 a famous calculation on r...
Strain determination in the Si channel above a single SiGe island inside a field effect transistor using nanobeam x-ray diffraction
Strain determination Si channel field effect transistor
2010/11/24
SiGe islands are used to induce tensile strain in the Si channel of Field E ect Transistors to achieve larger transconductance and higher current driveabilities. We report on x-ray di raction experime...
Linear amplification and quantum cloning for non-Gaussian continuous variables
Linear amplification quantum cloning non-Gaussian continuous variables
2010/10/19
We investigate phase-insensitive linear amplification at the quantum limit for single- and two-mode states and show that there exists a broad class of non-Gaussian states whose nonclassicality survive...
In this note, we survey some elementary theorems and proofs of dynamical matrices theory such that ones read them easily.
Zeno Paradox for Bohmian Trajectories: The Unfolding of the Metatron
Zeno Paradox Bohmian Trajectories Unfolding Metatron
2010/11/5
We study an analogue of the quantum Zeno paradox for the Bohm trajectory of a sharply located particle (or a system of particles). We show that a continuously observed Bohm trajectory is the classical...
Detecting entanglement of states by entries of their density matrices
Detecting entanglement states by entries their density matrices
2010/11/4
For any bipartite systems, a universal entanglement witness of rank-4 for pure states is obtained and a class of finite rank entanglement witnesses is constructed. In addition, a method of detecting e...
A perspectival version of the modal interpretation of quantum mechanics and the origin of macroscopic behavior
modal interpretation relational properties, measurement realism
2011/9/7
We study the process of observation (measurement), within the framework of a `perspectival' (`relational', `relative state')version of the modal interpretation of quantum mechanics. We show that if we...
Comparison of the hydrodynamic and Dirac models of the dispersion interaction between graphene and H, He${}^{\ast}$, or Na atoms
Comparison the hydrodynamic Dirac models the dispersion interaction between graphene
2010/10/29
The van der Waals and Casimir-Polder interaction of different atoms with graphene is investigated using the Dirac model which assumes that the energy of quasiparticles is linear with respect to the mo...
On the classical limit of quantum mechanics and the threat of fundamental graininess and chaos to the correspondence principle
classical limit of quantum mechanics fundamental graininess and chaos correspondence principle
2010/10/21
The aim of this paper is to review the classical limit of Quantum Mechanics and to precise the well known threat of chaos (and fundamental graininess) to the correspondence principle. We will introduc...
Tight Bounds for Classical and Quantum Coin Flipping
Tight Bounds for Classical Quantum Coin Flipping
2010/10/21
Coin flipping is a cryptographic primitive for which strictly better protocols exist if the
players are not only allowed to exchange classical, but also quantum messages. During the past
few years, ...
