Frustrated Heisenberg antiferromagnets: fluctuation induced first order vs deconfined quantum criticality
Frank Krüger, Stefan Scheidl
Recently it was argued that quantum phase transitions can be radically different from classical phase transitions with as a highlight the 'deconfined critical points' exhibiting fr…
Spin-wave dispersion in orbitally ordered La(0.5)Sr(1.5)MnO(4)
D. Senff, F. Krueger, S. Scheidl +4
The magnon dispersion in the charge, orbital and spin ordered phase in La(0.5)Sr(1.5)MnO(4) has been studied by means of inelastic neutron scattering. We find an excellent agreemen…
Quantum Phase Transitions of Frustrated Heisenberg Antiferromagnets: a Comprehensive Renormalization Approach
Frank Krüger, Stefan Scheidl
We develop a novel renormalization approach for frustrated quantum antiferromagnets. It is designed to consistently treat spin-wave interactions all over the magnetic Brillouin zon…
Rectification in Luttinger liquids
D. E. Feldman, S. Scheidl, V. M. Vinokur
We investigate the rectification of an ac bias in Luttinger liquids in the presence of an asymmetric potential (the ratchet effect). We show that strong repulsive electron interact…
The spin excitation spectrum in striped bilayer compounds
Frank Krüger, Stefan Scheidl
The spin dynamics of bilayer cuprate compounds are studied in a basic model. The magnetic spectral properties are calculated in linear spin-wave theory for several stripe configura…
Correlations in noisy Landau-Zener transitions
V. L. Pokrovsky, S. Scheidl
We analyze the influence of classical Gaussian noise on Landau-Zener transitions during a two-level crossing in a time-dependent regular external field. Transition probabilities an…
