The Potts model built on sand

E. Dinaburg, C. Maes, S. Pirogov +2

We consider the q=4 Potts model on the square lattice with an additional hard-core nonlocal interaction. That interaction arises from the choice of the reference measure taken to b…

Pattern forming pulled fronts: bounds and universal convergence

Ute Ebert, Willem Spruijt, Wim van Saarloos

We analyze the dynamics of pattern forming fronts which propagate into an unstable state, and whose dynamics is of the pulled type, so that their asymptotic speed is equal to the l…

Exciton bimolecular annihilation dynamics in supramolecular nanostructures of conjugated oligomers

Clément Daniel, Laura M. Herz, Carlos Silva +4

We present femtosecond transient absorption measurements on -conjugated supramolecular assemblies in a high pump fluence regime. Oligo(\emph{p}-phenylenevinylene) monofunctional…

The Kac limit for finite-range spin glasses

Silvio Franz, Fabio Lucio Toninelli

We consider a finite range spin glass model in arbitrary dimension, where the strength of the two-body coupling decays to zero over some distance . We show that, under mild…

Exponential distribution for the occurrence of rare patterns in Gibbsian random fields

M. Abadi, J. -R. Chazottes, F. Redig +1

We study the distribution of the occurrence of rare patterns in sufficiently mixing Gibbs random fields on the lattice , . A typical example is the high temp…

Covers of Point-Hyperplane Graphs

Arjeh M. Cohen, E. J. Postma

We construct a cover of the non-incident point-hyperplane graph of projective dimension 3 for fields of characteristic 2. If the cardinality of the field is larger than 2, we obtai…

Loss of coherence in double-slit diffraction experiments

A. S. Sanz, F. Borondo, M. J. Bastiaans

The effects of incoherence and decoherence in the double--slit experiment are studied using both optical and quantum--phenomenological models. The results are compared with experim…

BMW algebras of simply laced type

A. M. Cohen, D. A. H. Gijsbers, D. B. Wales

It is known that the recently discovered representations of the Artin groups of type A_n, the braid groups, can be constructed via BMW algebras. We introduce similar algebras of ty…

Metastable neon collisions: anisotropy and scattering length

V. P. Mogendorff, E. J. D. Vredenbregt, B. J. Verhaar +1

In this paper we investigate the effective scattering length of spin-polarized Ne*. Due to its anisotropic electrostatic interaction, its scattering length is determined by fiv…

Imaging of the [Mn2+(3d5) + hole] complex in GaAs by Cross-sectional Scanning Tunneling Microscopy

A. M. Yakunin, A. Yu. Silov, P. M. Koenraad +3

We present results on the direct spatial mapping of the wave-function of a hole bound to a Mn acceptor in GaAs. To investigate individual Mn dopants at the atomic scale in both ion…

Period doubling in glow discharges: local versus global differential conductivity

Danijela D. Sijacic, Ute Ebert, Ismail Rafatov

Short planar glow discharges coupled to a resistive layer exhibit a wealth of spontaneous spatio-temporal patterns. Several authors have suggested effective reaction-diffusion-mode…

Rapidly Rotating Bose-Einstein Condensates in and near the Lowest Landau Level

V. Schweikhard, I. Coddington, P. Engels +2

We create rapidly rotating Bose-Einstein condensates in the lowest Landau level, by spinning up the condensates to rotation rates of the centrifugal limit for a harmonicall…

Towards a Neo-Copenhagen Interpretation of Quantum Mechanics

W. M. de Muynck

The Copenhagen interpretation is critically considered. A number of ambiguities, inconsistencies and confusions are discussed. It is argued that it is possible to purge the interpr…

Radio-Frequency Spectroscopy of Ultracold Fermions

S. Gupta, Z. Hadzibabic, M. W. Zwierlein +6

Radio-frequency techniques were used to study ultracold fermions. We observed the absence of mean-field "clock" shifts, the dominant source of systematic error in current atomic cl…

Stability of negative ionization fronts: regularization by electric screening?

Manuel Arrayas, Ute Ebert

We recently have proposed that a reduced interfacial model for streamer propagation is able to explain spontaneous branching. Such models require regularization. In the present pap…

Replica bounds for diluted non-Poissonian spin systems

Silvio Franz, Michele Leone, Fabio Lucio Toninelli

In this paper we extend replica bounds and free energy subadditivity arguments to diluted spin-glass models on graphs with arbitrary, non-Poissonian degree distribution. The new di…

Streamer branching rationalized by conformal mapping techniques

B. Meulenbroek, A. Rocco, U. Ebert

Spontaneous branching of discharge channels is frequently observed, but not well understood. We recently proposed a new branching mechanism based on simulations of a simple continu…

Combinatorial problems in finite geometry and lacunary polynomials

Aart Blokhuis

We describe some combinatorial problems in finite projective planes and indicate how Rédei's theory of lacunary polynomials can be applied to them.

Surface-active dust in a plasma sheath

A. M. Ignatov, P. P. J. M. Schram, S. A. Trigger

The inhomogeneity of the plasma pressure near a conducting electrode is a cause for introducing the surface tension associated with the plasma-electrode interface. We evaluate the…

Random walks on FKG-horizontally oriented lattices

Nadine Guillotin-Plantard, Arnaud Le Ny

We study the asymptotic behavior of the simple random walk on oriented version of . The considered latticesare not directed on the vertical axis but unidirectional on…

An Introduction To Monte Carlo Simulations Of Surface Reactions

A. P. J. Jansen

These are lecture notes of a course that I gave to people doing research for their Ph.D. thesis in theoretical chemistry or spectroscopy. The course was given on December 9-13, 200…
