Momentum Signatures of Site Percolation in Disordered 2D Ferromagnets
Daniel Tay, Benoît Grémaud, Christian Miniatura
In this work, we consider a two-dimensional square lattice of pinned magnetic spins with nearest-neighbour interactions and we randomly replace a fixed proportion of spins with non…

Scattering Theory of Non-Equilibrium Noise and Delta current fluctuations through a quantum dot
A. Popoff, J. Rech, T. Jonckheere +4
We consider the non-equilibrium zero frequency noise generated by a temperature gradient applied on a device composed of two normal leads separated by a quantum dot. We recall the…

Pairing and superconductivity in quasi one-dimensional flat band systems: Creutz and sawtooth lattices
Si Min Chan, B. Grémaud, G. G. Batrouni
We study the pairing and superconducting properties of the attractive Hubbard model in two quasi one-dimensional topological lattices: the Creutz and sawtooth lattices. They share…
