After repeated pounding,antihydrogen reveals its charge:zero
repeated pounding antihydrogen charge zero
2016/2/22
An eight-hour experiment using the ALPHA trap at CERN confirmed with 20 times greater precision than before that the charge of the antihydrogen atom – the antimatter counterpart of the hydrogen atom –...
New evidence for zero-temperature relaxation in a spin-polarized Fermi liquid
The experiment report parameters and coefficients
2014/12/20
Spin-echo experiments are reported for 3He-4He solutions under extremely high B/T conditions, B=14.75 T and T≥1.73 mK. The 3He concentration x3 was adjusted close to the valu...
Numerical study of the three-dimensional random-field Ising model at zero and positive temperature
Three-dimensional ising model zero temperature heat capacity critical point
2014/12/20
In this paper the three-dimensional random-field Ising model is studied at both zero temperature and positive temperature. Critical exponents are extracted at zero temperature by finite size scaling a...
Regularization of Diagrammatic Series with Zero Convergence Radius
Expansion macroscopic system graphic technology system model diagram structure
2014/12/19
The divergence of perturbative expansions which occurs for the vast majority of macroscopic systems and follows from Dyson’s collapse argument prevents the direct use of Feynman’s diagrammatic techniq...
Analytical Study of Sub-Wavelength Imaging by Uniaxial Epsilon-Near-Zero Metamaterial Slabs
Analytical Study of Sub-Wavelength Uniaxial Epsilon-Near-Zero Metamaterial Slabs Optics
2012/5/29
We show that the two-dimensional Green's function of a uniaxial (with possibly tilted optical axis) epsilon-near-zero metamaterial slab, of interest for sub-wavelength imaging, can be calculated analy...
On the zero-field orbital magnetic susceptibility of Bloch electrons in graphene-like solids: Some rigorous results
Diamagnetism zero-field susceptibility two-dimensional electrons gas graphene semiconductors
2012/4/17
Starting with a nearest-neighbors tight-binding model, we rigorously investigate the bulk zero-field orbital susceptibility of a non-interacting Bloch electrons gas in graphene-like solids at fixed te...
Any Classical Description of Nature Requires Classical Electromagnetic Zero-Point Radiation
Classical Description Nature Electromagnetic Zero-Point Radiation
2011/8/5
Abstract: Any attempt to describe nature within classical physics requires the presence of Lorentz-invariant classical electromagnetic zero-point radiation so as to account for the Casimir forces betw...
Explanation of quantum interference: Classical trajectories plus ballistic diffusion caused by zero-point fluctuations
quantum mechanics, ballistic di usion, nonequilibrium thermodynamics, zero-point
2011/9/29
A purely classical explanation of quantum mechanical interference is given. We claim that for every single \particle" a thermal context can be de ned, which re ects its embedding within boundary condi...
Singularity-driven Second and Third Harmonic Generation in a ε-near-zero nanolayer
Singularity-driven Harmonic Generation ε-near-zero nanolayer
2011/8/4
Abstract: We show a new path to {\epsilon}~0 materials without resorting to metal-based metamaterial composites. A medium that can be modeled using Lorentz oscillators usually displays {\epsilon}=0 cr...
Magic-zero wavelengths of alkali-metal atoms and their applications
Magic-zero wavelengths alkali-metal atoms application Quantum Gases
2011/8/4
Abstract: Using first-principles calculations, we identify "magic-zero" optical wavelengths, \lambda_zero, for which the ground-state frequency-dependent polarizabilities of alkali-metal atoms vanish....
Near-zero-field nuclear magnetic resonance
Near-zero-field nuclear magnetic resonance Atomic Physics
2011/8/3
Abstract: We investigate nuclear magnetic resonance (NMR) in near-zero-field, where the Zeeman interaction can be treated as a perturbation to the electron mediated scalar interaction (J-coupling). Th...
Kramers-Kronig, Bode, and the meaning of zero
Kramers-Kronig Bode the meaning of zero Classical Physics
2011/8/1
Abstract: The implications of causality, as captured by the Kramers-Kronig relations between the real and imaginary parts of a linear response function, are familiar parts of the physics curriculum. I...
Absence of traveling wave solutions of conductivity type for the Novikov-Veselov equations at zero energy
traveling wave conductivity type the Novikov-Veselov equations zero energy
2011/7/27
Abstract: We prove that the Novikov-Veselov equation (an analog of KdV in dimension 2 + 1) at zero energy does not have sufficiently localized soliton solutions of conductivity type.
Decompositions of two player games: potential, zero-sum, and stable games

2011/7/28
Abstract: We introduce several methods of decomposition for two player normal form games. Viewing the set of all games as a vector space, we exhibit explicit orthonormal bases for the subspaces of pot...
Among several methods for accurate measurements of solar diameter, there are transits at fixed almucantarat used in solar astrolabes. The almucantarat is a circle of given height. The horizon circle i...
