"Safe" Coulomb Excitation of 30Mg

O. Niedermaier, H. Scheit, V. Bildstein +9

We report on the first radioactive beam experiment performed at the recently commissioned REX-ISOLDE facility at CERN in conjunction with the highly efficient gamma spectrometer MI…

Spectral Densities from Dynamic Density-Matrix Renormalization

Carsten Raas, Götz S. Uhrig

Dynamic density-matrix renormalization provides valuable numerical information on dynamic correlations by computing convolutions of the corresponding spectral densities. Here we di…

String Picture of a Frustrated Quantum Magnet and Dimer Model

Ying Jiang, Thorsten Emig

We map a geometrically frustrated Ising system with transversal field generated quantum dynamics to a strongly anisotropic lattice of non-crossing elastic strings. The combined eff…

Collective effects in traffic on bi-directional ant-trails

Alexander John, Andreas Schadschneider, Debashish Chowdhury +1

Motivated by recent experimental work of Burd et al., we propose a model of bi-directional ant-traffic on pre-existing ant-trails. It captures in a simple way some of the generic c…

5-dimensional contact SO(3)-manifolds and Dehn twists

Klaus Niederkrüger

In this paper the 5-dimensional contact SO(3)-manifolds are classified up to equivariant contactomorphisms. The construction of such manifolds with singular orbits requires the use…

Finite-Size Scaling Exponents of the Lipkin-Meshkov-Glick Model

S. Dusuel, J. Vidal

We study the ground state properties of the critical Lipkin-Meshkov-Glick model. Using the Holstein-Primakoff boson representation, and the continuous unitary transformation techni…
