Re-entrant melting and freezing in a model system of charged colloids

C. Patrick Royall, Mirjam E. Leunissen, Antti-Pekka Hynninen +2

We studied the phase behavior of charged and sterically stabilized colloids using confocal microscopy in a less polar solvent (dielectric constant 5.4). Upon increasing the colloid…

Hypermultiplets and Topological Strings

Martin Rocek, Cumrun Vafa, Stefan Vandoren

The c-map relates classical hypermultiplet moduli spaces in compactifications of type II strings on a Calabi-Yau threefold to vector multiplet moduli spaces via a further compactif…

Sedimentation of binary mixtures of like- and oppositely charged colloids: the primitive model or effective pair potentials?

M. Dijkstra, J. Zwanikken, R. van Roij

We study sedimentation equilibrium of low-salt suspensions of binary mixtures of charged colloids, both by Monte Carlo simulations of an effective colloids-only system and by Poiss…

Derivation of the generalized Non Linear Sigma Model in the presence of the Dzyaloshinskii-Moriya interaction

L. Benfatto, M. Silva Neto, V. Juricic +1

We derive the long-wavelength non-linear sigma model for a two-dimensional Heisenberg system in the presence of the Dzyaloshinskii-Moriya and pseudodipolar interactions. We show th…

An implementation of Runge's method for Diophantine equations

F. Beukers, Sz. Tengely

In this paper we suggest an implementation of Runge's method for solving Diophantine equations satisfying Runge's condition. In this implementation we avoid the use of Puiseux seri…

Improved Measurement of the b-bbar Production Cross Section in 920 GeV Fixed-Target Proton-Nucleus Collisions

B Collaboration, I. Abt

A new measurement of the b-bbar production cross section in 920 GeV proton-nucleus collisions is presented by the HERA-B collaboration. The b-bbar production is tagged via inclusiv…
