Raman Scattering from Magnetic Excitations in coupled Spin Ladders
R. Citro, E. Orignac
We consider Raman scattering of coupled two leg spin ladders in the Fleury-Loudon regime. We derive the dependence of the intensity with polarization of the incoming light and temp…
Meissner effect in a bosonic ladder
E. Orignac, T. Giamarchi
We investigate the effect of a magnetic field on a bosonic ladder. We show that such a system leads to the one dimensional equivalent of a vortex lattice in a superconductor. We in…
Disordered Quantum Solids
T. Giamarchi, E. Orignac
Due to the peculiar non-fermi liquid of one dimensional systems, disorder has particularly strong effects. We show that such systems belong to the more general class of disordered…
Raman Scattering cross section of Spin Ladders
E. Orignac, R. Citro
The Raman scattering spectra from magnetic excitations in an antiferromagnetic spin-1/2 two leg ladder is investigated for weak and strong interladder coupling. In the first case,…
