Dynamical delocalization in random Landau Hamiltonians
Francois Germinet, Abel Klein, Jeffrey H. Schenker
We prove the existence of dynamical delocalization for random Landau Hamiltonians near each Landau level. Since typically there is dynamical localization at the edges of each disor…
Multidimensional Gaussian sums arising from distribution of Birkhoff sums in zero entropy dynamical systems
M. Bernardo, M. Courbage, T. T. Truong
A duality formula, of the Hardy and Littlewood type for multidimensional Gaussian sums, is proved in order to estimate the asymptotic long time behavior of distribution of Birkhoff…
Electronic structure of complex spd Hume-Rothery phases in transition-metal aluminides
Guy Trambly De Laissardière, Duc Nguyen-Manh, Didier Mayou
The discovery of quasicrystals phases and approximants in Al(rich)-Mn system has revived the interest for complex aluminides containing transition-metal atoms. On one hand, it is n…
On osp(M|2n) integrable open spin chains
Daniel Arnaudon, Jean Avan, Nicolas Crampe +3
We consider open spin chains based on osp(m|2n) Yangians. We solve the reflection equations for some classes of reflection matrices, including the diagonal ones. Having then integr…
Effects of Frustrated Surface in Heisenberg Thin Films
V. Thanh Ngo, H. T. Diep
We study by extensive Monte Carlo (MC) simulations and analytical Green function (GF) method effects of frustrated surfaces on the properties of thin films made of stacked triangul…
On the spin-spin correlation functions of the XXZ spin-1/2 infinite chain
N. Kitanine, J. M. Maillet, N. A. Slavnov +1
We obtain a new multiple integral representation for the spin-spin correlation functions of the XXZ spin-1/2 infinite chain. We show that this representation is closely related wit…
Dynamical correlation functions of the XXZ spin-1/2 chain
N. Kitanine, J. M. Maillet, N. A. Slavnov +1
We derive a master equation for the dynamical spin-spin correlation functions of the XXZ spin-1/2 Heisenberg finite chain in an external magnetic field. In the thermodynamic limit,…
Master equation for spin-spin correlation functions of the XXZ chain
N. Kitanine, J. M. Maillet, N. A. Slavnov +1
We derive a new representation for spin-spin correlation functions of the finite XXZ spin-1/2 Heisenberg chain in terms of a single multiple integral, that we call the master equat…
On the dimensions of conformal repellers. Randomness and parameter dependency
Hans Henrik Rugh
Bowen's formula relates the Hausdorff dimension of a conformal repeller to the zero of a `pressure' function. We present an elementary, self-contained proof which bypasses measure…
General boundary conditions for the sl(N) and sl(M|N) open spin chains
Daniel Arnaudon, Jean Avan, Nicolas Crampe +3
Two types of boundary conditions ("soliton preserving" and "soliton non-preserving") are investigated for the sl(n) and sl(m|n) open spin chains. The appropriate reflection equatio…
Oscillator strengths for transitions to Rydberg levels in , and between 967 and 972 A
M. Eidelsberg, J. L. Lemaire, J. H. Fillion +3
Absorption oscillator strengths have been determined from high-resolution spectra in the 967-972 Åregion of three CO isotopomers for transitions to the Rydberg levels 4{\it p}(0…
Phases of the generalized two-leg spin ladder: A view from the SU(4) symmetry
P. Lecheminant, K. Totsuka
The zero-temperature phases of a generalized two-leg spin ladder with four-spin exchanges are discussed by means of a low-energy field theory approach starting from an SU(4) quantu…
Vacancy-Impurity Nanoclusters in Solid Solutions
Dimitar I. Pushkarov
The existence of vacancy--impurity clusters due to quantum properties of vacancies in phase separated solid solutions of 4He in 3He is analyzed and discussed. Additional mechanism…
Quantum Hall-like effect on strips due to geometry
R. Dandoloff, T. T. Truong
In this Letter we present an exact calculation of the effective potential which appears on a helicoidal strip. This potential leads to the appearance of lcalized states at a distan…
Commuting quantum traces for quadratic algebras
Zoltan Nagy, Jean Avan, Anastasia Doikou +1
Consistent tensor products on auxiliary spaces, hereafter denoted "fusion procedures", are defined for general quadratic algebras, non-dynamical and dynamical, inspired by results…
Effect of a lattice upon an interacting system of electrons in two dimensions: Breakdown of scaling and decay of persistent currents
Houman Falakshahi, Zoltán Ádám Németh, Jean-Louis Pichard
The ground state of an electron gas is characterized by the interparticle spacing to the effective Bohr radius ratio r_s=a/a_B*. For polarized electrons on a two dimensional square…
