Phase diagram of hard-core bosons on a frustrated zig-zag ladder
Davide Rossini, Valeria Lante, Alberto Parola +1
We study hard-core bosons with unfrustrated nearest-neighbor hopping and repulsive interaction on a zig-zag ladder. As a function of the boson density and , the gr…
Spin-charge decoupling and the photoemission line-shape in one dimensional insulators
Valeria Lante, Alberto Parola
The recent advances in angle resolved photoemission techniques allowed the unambiguous experimental confirmation of spin charge decoupling in quasi one dimensional (1D) Mott insula…
Spin-Peierls instabilities of antiferromagnetic rings in a magnetic field
Valeria Lante, Ioannis Rousochatzakis, Karlo Penc +2
Motivated by the intriguing properties of magnetic molecular wheels at field induced level crossings, we investigate the spin-Peierls instability of antiferromagnetic rings in a fi…
Magneto-elastic effects and magnetization plateaus in two dimensional systems
Samuele Bissola, Valeria Lante, Alberto Parola +1
We show the importance of both strong frustration and spin-lattice coupling for the stabilization of magnetization plateaus in translationally invariant two-dimensional systems. We…
The Ising phase in the J1-J2 Heisenberg Model
V. Lante, A. Parola
The two dimensional Heisenberg antiferromagnet on the square lattice with nearest (J1) and next-nearest (J2) neighbor couplings is investigated in the strong frustration regime (J2…
