Time-resolved broadband analysis of slow-light propagation and superluminal transmission of electromagnetic waves in three-dimensional photonic crystals
J. Gomez Rivas, A. Farre Benet, J. Niehusmann +2
A time-resolved analysis of the amplitude and phase of THz pulses propagating through three-dimensional photonic crystals is presented. Single-cycle pulses of THz radiation allow m…
Orbital currents and charge density waves in a generalized Hubbard ladder
J. O. Fjaerestad, J. B. Marston, U. Schollwoeck
We study a generalized Hubbard model on the two-leg ladder at zero temperature, focusing on a parameter region with staggered flux (SF)/d-density wave (DDW) order. To guide our num…
Ground-state phases in antiferromagnetic spin-crossover chains
Carsten Timm, Ulrich Schollwöck
Spin-crossover molecules having a low-spin ground state and a low-lying excited high-spin state are promising components for molecular electronics. We theoretically examine one-dim…
Ising and anisotropic Heisenberg magnets with mobile defects
M. Holtschneider, R. Leidl, W. Selke
Motivated by experiments on (Sr,Ca,La)_14 Cu_24 O_41, a two-dimensional Ising model with mobile defects and a two-dimensional anisotropic Heisenberg antiferromagnet have been propo…
Ageing phenomena without detailed balance: the contact process
Tilman Enss, Malte Henkel, Alan Picone +1
The long-time dynamics of the 1D contact process suddenly brought out of an uncorrelated initial state is studied through a light-cone transfer-matrix renormalisation group approac…
Defining relations of invariants of two 3 \times 3 matrices
Helmer Aslaksen, Vesselin Drensky, Liliya Sadikova
Over a field of characteristic 0, the algebra of invariants of several matrices under simultameous conjugation by is generated by traces of products of generic m…
