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…
A route to high temperature superconductivity in composite systems
E. Berg, D. Orgad, S. A. Kivelson
Apparently, some form of local superconducting pairing persists to temperatures well above the maximum observed in underdoped cuprates, \textit{i.e.} is suppressed due…
Enhancement of the superconducting transition temperature in La2-xSrxCuO4 bilayers: Role of pairing and phase stiffness
Ofer Yuli, Itay Asulin, Leonid Iomin +3
The superconducting transition temperature, Tc, of bilayers comprising underdoped La2-xSrxCuO4 films capped by a thin heavily overdoped metallic La1.65Sr0.35CuO4 layer, is found to…
Spectral signatures of modulated d-wave superconducting phases
Shirit Baruch, Dror Orgad
We calculate within a mean-field theory the spectral signatures of various striped d-wave superconducting phases. We consider both in-phase and anti-phase modulations of the superc…
