Inhomogeneous Phases in a Double-Exchange Magnet with Long Range Coulomb Interactions
Gideon Wachtel, Dror Orgad, D. I. Golosov
We consider a model with competing double-exchange (ferromagnetic) and super-exchange (anti-ferromagnetic) interactions in the regime where phase separation takes place. The presen…
Twist instability in strongly correlated carbon nanotubes
Wei Chen, A. V. Andreev, A. M. Tsvelik +1
We show that strong Luttinger correlations of the electron liquid in armchair carbon nanotubes lead to a significant enhancement of the onset temperature of the putative twist Peie…
Boundary Energies and the Geometry of Phase Separation in Double--Exchange Magnets
D. I. Golosov, D. Orgad
We calculate the energy of a boundary between ferro- and antiferromagnetic regions in a phase separated double-exchange magnet in two and three dimensions. The orientation dependen…
Disorder Effects in Fluctuating One-Dimensional Interacting Systems
U. London, T. Giamarchi, D. Orgad
The zero temperature localization of interacting electrons coupled to a two-dimensional quenched random potential, and constrained to move on a fluctuating one-dimensional string e…
Weak-coupling phase diagrams of bond-aligned and diagonal doped Hubbard ladders
Shirit Baruch, Dror Orgad
We study, using a perturbative renormalization group technique, the phase diagrams of bond-aligned and diagonal Hubbard ladders defined as sections of a square lattice with nearest…
Interacting Electrons on a Fluctuating String
Dror Orgad
We consider the problem of interacting electrons constrained to move on a fluctuating one-dimensional string. An effective low-energy theory for the electrons is derived by integra…
