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...
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...
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...
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....
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
zero-sum decomposition pure strategy ESS Systems and Control
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...

Optically controllable photonic structures with zero absorption
Optically photonic structures zero absorption
2011/9/9
We show the possibility to periodically modulate refractive index in atomic medium in space or/and time while simultaneously keeping vanishing absorption/gain. Such modulation is based on periodic res...
We propose a new criterion for judging zero quantum discord for arbitrary bipartite states. A bipartite quantum state has zero quantum discord if and only if all the blocks of its density matrix are n...
Counting Majorana zero modes in superconductors
Counting Majorana zero modes superconductors
2010/12/24
A counting formula for computing the number of (Majorana) zero modes bound to topological point defects is evaluated in a gradient expansion for systems with charge-conjugation symmetry. This semi-cl...
Min-entropy and quantum key distribution: non-zero key rates for "small" numbers of signals
min-entropy quantum key distribution non-zero key rates
2010/11/8
We calculate an achievable secret key rate for quantum key distribution with a finite number of signals, by evaluating the min-entropy explicitly. The min-entropy can be expressed in terms of the gues...
