Magnetic excitations in dipolar pyrochlore antiferromagnet GdSnO
S. S. Sosin, L. A. Prozorova, P. Bonville +1
The spin dynamics in the geometrically frustrated pyrochlore antiferromagnet is studied by means of the electron spin resonance. In the ordered phase ( K…
Momentum deficit in quantum glasses
A. F. Andreev
Using the concept of tunneling two level systems we explain the reduction of rotational inertia of disordered solid 4He observed in the torsional oscillator experiments. The key po…
Ion-Size Effect at the Surface of a Silica Hydrosol
Aleksey M. Tikhonov
The author used synchrotron x-ray reflectivity to study the ion-size effect for alkali ions (Na, K, Rb, and Cs), with densities as high as $4 \times 10^{18}- 7 \tim…
Preparation of facilities for fundamental research with ultracold neutrons at PNPI
A. P. Serebrov, V. A. Mityuklyaev, A. A. Zakharov +13
The WWR-M reactor of PNPI offers a unique opportunity to prepare a source for ultracold neutrons (UCN) in an environment of high neutron flux (about 3*10^12 n/cm^2/s) at still acce…
Co-existing chiral and collinear phases in a distorted triangular antiferromagnet
A. I. Smirnov, L. E. Svistov, L. A. Prozorova +10
The entire magnetic phase diagram of the quasi two dimensional (2D) magnet on a distorted triangular lattice KFe(MoO4)2 is outlined by means of magnetization, specific heat, and ne…
Evidence for orthorhombic distortions in the ordered state of ZnCrO: A magnetic resonance study
V. N. Glazkov, A. M. Farutin, V. Tsurkan +2
We present an elaborate electron-spin resonance study of the low-energy dynamics and magnetization in the ordered phase of the magnetically frustrated spinel ZnCrO. We obse…
Effect of correlated disorder on the temperature of unconventional Cooper pairing (3He in aerogel)
I. A. Fomin
Using liquid 3He in aerogel as an example, it is shown that correlations in positions of impurities affect the temperature of transition of Fermi liquid in an unconventional…
Is ϕ^4 theory trivial ?
I. M. Suslov
The four-dimensional ϕ^4 theory is usually considered to be trivial in the continuum limit. In fact, two definitions of triviality were mixed in the literature. The first one, intr…
Equation of state and effective mass of the unitary Fermi gas in a 1D periodic potential
Gentaro Watanabe, Giuliano Orso, Franco Dalfovo +2
By solving the Bogoliubov -- de Gennes equations at zero temperature, we study the effects of a one-dimensional optical lattice on the behavior of a superfluid Fermi gas at unitari…
Quantum Electrodynamics at Extremely Small Distances
I. M. Suslov
The asymptotics of the Gell-Mann - Low function in QED can be determined exactly, β(g)= g at g\to\infty, where g=e^2 is the running fine structure constant. It solves the problem o…
Analytical asymptotics of β-function in ϕ^4 theory (end of the "zero charge" story)
I. M. Suslov
Reconstruction of the β-function for ϕ^4 theory, attempted previously by summation of perturbation series, leads to asymptotics β(g)=β_\infty g^αat g\to\infty, where α\approx 1 for…
Comparison of the scaling analysis of the mixed-state magnetization data with direct measurements of the upper critical field in Y-123
I. L. Landau
By comparison of recent direct measurements of the temperature dependence of the upper critical field in an Y-123 high temperature superconductor with the scaling analysis…
Localization Theory in Zero Dimension and the Structure of Diffusion Poles
I. M. Suslov
The 1/[-iω+ D(ω, q)q^2] diffusion pole in the localized phase transfers to the 1/ωBerezinskii-Gorkov singularity, which can be analyzed by the instanton method (M V. Sadovskii, 198…
Spin Dynamics of in the Field-Induced Ordered Phase
S. A. Zvyagin, J. Wosnitza, A. K. Kolezhuk +6
- (known as DTN) is a spin-1 material with a strong single-ion anisotropy that is regarded as a new candidate for Bose-Einstein condensation (BEC) of spin deg…
Possibility of the 2D Anderson Transition and Generalized Lyapunov Exponents
I. M. Suslov
The possible existence of the Anderson transition in 2D systems without interaction and spin-orbit effects (such as the usual Anderson model) becomes recently a subject of controve…
Critical Exponents from Field Theory: New Evaluation
A. A. Pogorelov, I. M. Suslov
We present new evaluation of the critical exponents of O(n)- symmetric ϕ^4 theory from the field theoretical renormalization group, based on the new algorithm for summing divergent…
Solitons in two-dimensional Bose-Einstein condensates
Shunji Tsuchiya, Franco Dalfovo, Lev P. Pitaevskii
The excitations of a two-dimensional (2D) Bose-Einstein condensate in the presence of a soliton are studied by solving the Kadomtsev-Petviashvili equation which is valid when the v…
