Current-Induced Motion of Narrow Domain Walls and Dissipation in Ferromagnetic Metals
M. Benakli, J. Hohlfeld, A. Rebei
Spin transport equations in a non-homogeneous ferromagnet are derived in the limit where the sd exchange coupling between the electrons in the conduction band and those in the d ba…
Bounday Condition histograms for modulated phases
M. Benakli, M. Gabay, W. M. Saslow
Boundary conditions strongly affect the results of numerical computations for finite size inhomogeneous or incommensurate structures. We present a method which allows to deal with…
Smecticlike phase for modulated XY spins in two dimensions
M. Gabay, M. Benakli, W. M. Saslow
The row model for frustrated XY spins on a triangular lattice in 2D is used to study incommensurate{IC}) spiral and commensurate{C} antiferromagnetic (AF) phases, in the regime whe…
Diluted Josephson-junction arrays in a magnetic field: phase coherence and vortex glass thresholds
M. Benakli, E. Granato, S. R. Shenoy +1
The effects of random dilution of junctions on a two-dimensional Josephson-junction array in a magnetic field are considered. For rational values of the average flux quantum per pl…
Phase transitions in a frustrated XY model with zig-zag couplings
M. Benakli, E. Granato
We study a new generalized version of the square-lattice frustrated XY model where unequal ferromagnetic and antiferromagnetic couplings are arranged in a zig-zag pattern. The rati…
Thermal excitations of frustated XY spins in two dimensions
M. Benakli, H. Zheng, M. Gabay
We present a new variational approach to the study of phase transitions in frustrated 2D XY models. In the spirit of Villain's approach for the ferromagnetic case we divide thermal…
Analytical results for Scaling Properties of the Spectrum of the Fibonacci Chain
F. Piéchon M. Benakli, A. Jagannathan
We solve the approximate renormalisation group found by Qiu Niu and Franco Nori(Phys. Rev. Lett. 57 2057(1986)) for a tight-binding hamiltonian on the Fibonacci chain. This enables…
Phase Transitions of Frustrated XY spins in Two Dimensions
M. Benakli, M. Gabay, W. M. Saslow
The row model is used to study the commensurate-incommensurate (C-IC) an isotropic (FFTXY) transitions of the frustrated 2D XY model on the triangular lattice. New relevant variabl…
