Geometry induced potential on a 2D-section of a wormhole: catenoid
Rossen Dandoloff, Avadh Saxena, Bjorn Jensen
We show that a two dimensional wormhole geometry is equivalent to a catenoid, a minimal surface. We then obtain the curvature induced geometric potential and show that the ground s…
Poisson Structures of Calogero-Moser and Ruijsenaars-Schneider Models
Inês Aniceto, Jean Avan, Antal Jevicki
We examine the Hamiltonian structures of some Calogero-Moser and Ruijsenaars-Schneider N-body integrable models. We propose explicit formulations of the bihamiltonian structures fo…
Theory and Simulation of Spin Transport in Antiferromagnetic Semiconductors: Application to MnTe
K. Akabli, Yann Magnin, Masataka Oko +2
We study in this paper the parallel spin current in an antiferromagnetic semiconductor thin film where we take into account the interaction between itinerant spins and lattice spin…
VLT/NACO near-infrared imaging and spectroscopy of N88A in the SMC
G. Testor, J. L. Lemaire, M. Heydari-Malayeri +3
We present near-infrared imaging and spectroscopic high spatial resolution observations of the SMC region N88 containing the bright, excited, extincted and compact H II region N88A…
State-independent quantum violation of noncontextuality in four dimensional space using five observables and two settings
Alok Kumar Pan, Dipankar Home
Recently, a striking experimental demonstration [G. Kirchmair \emph{et al.}, Nature, \textbf{460}, 494(2009)] of the state-independent quantum mechanical violation of non-contextua…
Layering in the Ising model
K. S. Alexander, F. M. Dunlop, S. Miracle-Sole
We consider the three-dimensional Ising model in a half-space with a boundary field (no bulk field). We compute the low-temperature expansion of layering transition lines.
Quantum mechanics of a constrained electrically charged particle in the presence of electric currents
B. Jensen, R. Dandoloff
We discuss the dynamics of a classical spinless quantum particle carrying electric charge and constrained to move on a non singular static surface in ordinary three dimensional spa…
On polynomial integrals over the orthogonal group
Teodor Banica, Benoit Collins, Jean-Marc Schlenker
We consider integrals of type , with respect to the Haar measure on the orthogonal group. We establish severa…
On Blowup for time-dependent generalized Hartree-Fock equations
Christian Hainzl, Enno Lenzmann, Mathieu Lewin +1
We prove finite-time blowup for spherically symmetric and negative energy solutions of Hartree-Fock and Hartree-Fock-Bogoliubov type equations, which describe the evolution of attr…
An interplay between nonlocality and quantum violation of path-spin noncontextuality
Dipankar Home, Alok Kumar Pan
In terms of a suitable variant of the EPR-Bohm example, we argue that the quantum mechanically predicted and experimentally verified violation of a Bell-type path-spin noncontextua…
A Fresh Look at Coding for q-ary Symmetric Channels
Claudio Weidmann, Gottfried Lechner
This paper studies coding schemes for the -ary symmetric channel based on binary low-density parity-check (LDPC) codes that work for any alphabet size , ,…
Stochastic aspects of easy quantum groups
Teodor Banica, Stephen Curran, Roland Speicher
We consider several orthogonal quantum groups satisfying the easiness assumption axiomatized in our previous paper. For each of them we discuss the computation of the asymptotic la…
Information and (co-)variances in discrete evolutionary genetics involving solely selection
Thierry Huillet
The purpose of this Note is twofold: First, we introduce the general formalism of evolutionary genetics dynamics involving fitnesses, under both the deterministic and stochastic se…
Universality of collapsing two-dimensional self-avoiding trails
D P Foster
Results of a numerically exact transfer matrix calculation for the model of Interacting Self-Avoiding Trails are presented. The results lead to the conclusion that, at the collapse…
Layering and wetting transitions for an SOS interface
Kenneth S. Alexander, François Dunlop, Salvador Miracle-Solé
We study the solid-on-solid interface model above a horizontal wall in three dimensional space, with an attractive interaction when the interface is in contact with the wall, at lo…
The t-Martin boundary of reflected random walks on a half-space
Irina Ignatiouk-Robert
The t-Martin boundary of a random walk on a half-space with reflected boundary conditions is identified. It is shown in particular that the t-Martin boundary of such a random walk…
De Finetti theorems for easy quantum groups
Teodor Banica, Stephen Curran, Roland Speicher
We study sequences of noncommutative random variables which are invariant under "quantum transformations" coming from an orthogonal quantum group satisfying the "easiness" conditio…
Boundary Lax pairs from non-ultra local Poisson algebras
Jean Avan, Anastasia Doikou
We consider non-ultra local linear Poisson algebras on a continuous line . Suitable combinations of representations of these algebras yield representations of novel generalized lin…
Quantum anticentrifugal force for wormhole geometry
Rossen Dandoloff
We show the existence of an anticentrifugal force in a wormhole geometry in . This counterintuitive force was shown to exist in a flat space. The role the geometry plays…
Strongly correlated phases in rapidly rotating Bose gases
Mathieu Lewin, Robert Seiringer
We consider a system of trapped spinless bosons interacting with a repulsive potential and subject to rotation. In the limit of rapid rotation and small scattering length, we rigor…
The orthogonal Weingarten formula in compact form
Teodor Banica
We present a compact formulation of the orthogonal Weingarten formula, with the traditional quantity $I(i_1,...,i_{2k}:j_1,...,j_{2k}) = \int_{O_n}u_{i_1j_1} ... u_{i_{2k}j_{2k}} d…
The Busy Beaver Competition: a historical survey
Pascal Michel
Tibor Rado defined the Busy Beaver Competition in 1962. He used Turing machines to give explicit definitions for some functions that are not computable and grow faster than any com…
Haldane charge conjecture in one-dimensional multicomponent fermionic cold atoms
H. Nonne, P. Lecheminant, S. Capponi +2
A Haldane conjecture is revealed for spin-singlet charge modes in 2N-component fermionic cold atoms loaded into a one-dimensional optical lattice. By means of a low-energy approach…
Quantum isometries and noncommutative spheres
Teodor Banica, Debashish Goswami
We introduce and study two new examples of noncommutative spheres: the half-liberated sphere, and the free sphere. Together with the usual sphere, these two spheres have the proper…
