Direct Observation of Magnon Fractionalization in the Quantum Spin Ladder

B. Thielemann, Ch. Rüegg, H. M. Rønnow +12

We measure by inelastic neutron scattering the spin excitation spectra as a function of applied magnetic field in the quantum spin-ladder material (C5H12N)2CuBr4. Discrete magnon m…

Delayed coupling theory of vertebrate segmentation

Luis G. Morelli, Saul Ares, Leah Herrgen +3

Rhythmic and sequential subdivision of the elongating vertebrate embryonic body axis into morphological somites is controlled by an oscillating multicellular genetic network termed…

Designing and understanding directional emission from spiral microlasers

Martina Hentschel, Tae-Yoon Kwon

The availability of microlasers with highly directional far-field characteristics is crucial for future applications. To this end we study the far-field emission of active microcav…

Local density of states in disordered graphene

Klaus Ziegler, Balázs Dóra, Peter Thalmeier

We study two lattice models, the honeycomb lattice (HCL) and a special square lattice (SQL), both reducing to the Dirac equation in the continuum limit. In the presence of disorder…

Transmission thresholds in time-periodically driven nonlinear disordered systems

Magnus Johansson, Georgios Kopidakis, Stefano Lepri +1

We study energy propagation in locally time-periodically driven disordered nonlinear chains. For frequencies inside the band of linear Anderson modes, three different regimes are o…

The antiferromagnetic spin-1/2 Heisenberg model on the square lattice in a magnetic field

Andreas Luscher, Andreas Laeuchli

We study the field dependence of the antiferromagnetic spin-1/2 Heisenberg model on the square lattice by means of exact diagonalizations. In a first part, we calculate the spin-wa…
