Crossover from Wannier-Stark localization to charge density waves for interacting spinless fermions in one dimension
Nair Aucar Boidi, Amnon Aharony, Ora Entin-Wohlman +2
We study spinless fermions on a finite chain with nearest-neighbor repulsion and in the presence of a Wannier-Stark linearly-varying electric field potential. In the absence of the…
Coexistence of insulating phases in confined fermionic chains with a Wannier-Stark potential
N. Aucar Boidi, K. Hallberg, A. Aharony +1
We study fermions on a finite chain, interacting repulsively when residing on the same and on nearest-neighbor sites, and subjected to a Wannier-Stark linearly-varying potential. U…
Complex magnetic order in the kagome staircase compound Co3V2O8
Y. Chen, J. W. Lynn, Q. Huang +9
Co3V2O8 (CVO) has a geometrically frustrated magnetic lattice, a Kagome staircase. The crystal structure consists of two inequivalent Co sites, one-dimensional chains of Co(2) spin…
Field dependence of magnetic ordering in Kagome-staircase compound Ni3V2O8
M. Kenzelmann, A. B. Harris, A. Aharony +11
We present powder and single-crystal neutron diffraction and bulk measurements of the Kagome-staircase compound Ni3V2O8 (NVO) in fields up to 8.5T applied along the c-direction. (T…
The spin-wave spectrum of the Jahn-Teller system LaTiO3
Robert Schmitz, Ora Entin-Wohlman, Amnon Aharony +2
We present an analytical calculation of the spin-wave spectrum of the Jahn-Teller system LaTiO3. The calculation includes all superexchange couplings between nearest-neighbor Ti io…
The magnetic structure of the Jahn-Teller System LaTiO3
Robert Schmitz, Ora Entin-Wohlman, Amnon Aharony +2
We investigate the effect of the experimentally observed Jahn-Teller distortion of the oxygen octahedra in LaTiO3 on the magnetic exchange. We present a localized model for the eff…
