Neutral modes edge state dynamics through quantum point contacts
Dario Ferraro, Alessandro Braggio, Nicodemo Magnoli +1
Dynamics of neutral modes for fractional quantum Hall states is investigated for a quantum point contact geometry in the weak-backscattering regime. The effective field theory intr…
Theoretical prediction of multiferroicity in double perovskite YNiMnO
Sanjeev Kumar, Gianluca Giovannetti, Jeroen van den Brink +1
We put forward double perovskites of the RNiMnO family (with a rare-earth atom) as a new class of multiferroics on the basis of {\it ab initio} density functional calcu…
Multiferroicity in rare-earth nickelates RNiO3
Gianluca Giovannetti, Sanjeev Kumar, Daniel Khomskii +2
We show that charge ordered rare-earth nickelates of the type RNiO3 (R= Ho, Lu, Pr and Nd) are multiferroic with very large magnetically induced ferroelectric (FE) polarizations. T…
When finite-size corrections vanish: The S=1/2 XXZ model and the Razumov-Stroganov state
Leonardo Banchi, Filippo Colomo, Paola Verrucchi
We study the one-dimensional XXZ model on a finite lattice at zero temperature, varying the exchange anisotropy and the number of sites of the lattice. Special emph…
Signatures of the super fluid-insulator phase transition in laser driven dissipative nonlinear cavity arrays
A. Tomadin, V. Giovannetti, R. Fazio +4
We analyze the non-equilibrium dynamics of a gas of interacting photons in an array of coupled dissipative nonlinear cavities driven by a pulsed external coherent field. Using a me…
