Analytical realization of finite-size scaling for Anderson localization. Does the band of critical states exist for d>2?
I. M. Suslov
An analytical realization is suggested for the finite-size scaling algorithm based on the consideration of auxiliary quasi-1D systems. Comparison of the obtained analytical results…
Onset of turbulence in superfluid 3He-B and its dependence on vortex injection in applied flow
A. P. Finne, R. Blaauwgeers, S. Boldarev +3
Vortex dynamics in 3He-B is divided by the temperature dependent damping into a high-temperature regime, where the number of vortices is conserved, and a low-temperature regime, wh…
High-Field Low-Frequency Spin Dynamics
A. M. Farutin, V. I. Marchenko
The theory of exchange symmetry of spin ordered states is extended to the case of high magnetic field. Low frequency spin dynamics equation for quasi-goldstone mode is derived for…
ESR study of the single-ion anisotropy in the pyrochlore antiferromagnet Gd2Sn2O7
V. N. Glazkov, A. I. Smirnov, J. P. Sanchez +3
Single-ion anisotropy is of importance for the magnetic ordering of the frustrated pyrochlore antiferromagnets Gd2Ti2O7 and Gd2Sn2O7. The anisotropy parameters for the Gd2Sn2O7 wer…
Effect of a quenched disorder on the order parameter of superfluid 3He
I. A. Fomin
As a consequence of a continuous degeneracy of the order parameter of the superfluid 3He the quenched disorder in a form of aerogel gives rise both to a disruption of the orientati…
Divergent Perturbation Series
I. M. Suslov
Various perturbation series are factorially divergent. The behavior of their high-order terms can be found by Lipatov's method, according to which they are determined by the saddle…
Renormalons and Analytic Properties of the βfunction
I. M. Suslov
The presence or absense of renormalon singularities in the Borel plane is shown to be determined by the analytic properties of the Gell-Mann - Low function β(g) and some other func…
High-Order Corrections to the Lipatov Asymptotics in the ϕ^4 Theory
D. A. Lobaskin, I. M. Suslov
High orders in perturbation theory can be calculated by the Lipatov method. For most field theories, the Lipatov asymptotics has the functional form c a^N Γ(N+b) (N is the order of…
Magnetic resonance study of the spin-reorientation transitions in the quasi-one-dimensional antiferromagnet BaCu2Si2O7
V. N. Glazkov, A. I. Smirnov, A. Revcolevschi +1
A quasi-one dimensional antiferromagnet with a strong reduction of the ordered spin component, BaCu2Si2O7, is studied by the magnetic resonance technique in a wide field and freque…
Self-consistent theory for molecular instabilities in a normal degenerate Fermi gas in the BEC-BCS crossover
R. Combescot, X. Leyronas, M. Yu. Kagan
We investigate within a self-consistent theory the molecular instabilities arising in the normal state of a homogeneous degenerate Fermi gas, covering the whole BEC-BCS crossover.…
Single-ion anisotropy in the gadolinium pyrochlores studied by an electron paramagnetic resonance
V. N. Glazkov, M. E. Zhitomirsky, A. I. Smirnov +4
The electron paramagnetic resonance is used to measure the single-ion anisotropy of Gd3+ ions in the pyrochlore structure of (Y{1-x}Gdx)2Ti2O7. A rather strong easy-plane type anis…
Gravitating global monopoles in extra dimensions and the brane world concept
K. A. Bronnikov, B. E. Meierovich
Multidimensional configurations with Minkowski external space-time and a spherical global monopole in extra dimensions are discussed in the context of the brane world concept. The…
Bound states of three and four resonantly interacting particles
I. V. Brodsky, A. V. Klaptsov, M. Yu. Kagan +2
We present an exact diagrammatic approach for the problem of dimer-dimer scattering in 3D for dimers being a resonant bound state of two fermions in a spin-singlet state, with corr…
Polarization of Dielectrics by Acceleration
L. A. Melnikovsky
We argue that acceleration induces electric polarization in usual dielectrics. Both accelerations in superfluid participate in the medium polarization. Excitations contribution to…
Superfluid phases of 3He in aerogel
I. A. Fomin
Formal derivation of criterion for selection of superfluid phases of 3He in aerogel is presented. At the strength of the derived criterion variation of the order parameter of B-lik…
New asymptotic behaviour of the surface-atom force out of thermal equilibrium
Mauro Antezza, Lev P. Pitaevskii, Sandro Stringari
The Casimir-Polder-Lifshitz force felt by an atom near the surface of a substrate is calculated out of thermal equilibrium in terms of the dielectric function of the material and o…
Analytical realization of finite-size scaling for Anderson localization: Is there transition in the 2D case?
I. M. Suslov
Roughly half of numerical investigations of the Anderson transition are based on consideration of an associated quasi-1D system and postulation of one-parameter scaling for the min…
Formation of molecules near a Feshbach resonance in a 1D optical lattice
G. Orso, L. P. Pitaevskii, S. Stringari +1
We calculate the binding energy of two atoms interacting near a Feshbach resonance in the presence of a 1D periodic potential. The critical value of the scattering length needed to…

I. L. Landau, H. R. Ott
We reanalyze published magnetization data and demonstrate that the conclusion of the original authors, claiming enhanced two-dimensional properties of the cuprate superconductor Tl…
