Kondo effect in graphene with Rashba spin-orbit coupling
Diego Mastrogiuseppe, Arturo Wong, Kevin Ingersent +2
We study the Kondo screening of a magnetic impurity adsorbed in graphene in the presence of Rashba spin-orbit interaction. The system is described by an effective single-channel An…
Quantum phase transitions into Kondo states in bilayer graphene
Diego Mastrogiuseppe, Arturo Wong, Kevin Ingersent +2
We study a magnetic impurity intercalated in bilayer graphene. A representative configuration generates a hybridization function with strong dependence on the conduction-electron e…
Generation of chiral solitons in antiferromagnetic chains by a quantum quench
Barbara Bravo, Ariel Dobry, Diego Mastrogiuseppe +1
We analyze the time evolution of a magnetic excitation in a spin-1/2 antiferromagnetic Heisenberg chain after a quantum quench. By a proper modulation of the magnetic exchange coup…
Incommensurate spin Luttinger liquid phase in a model for the spin-Peierls materials TiOBr and TiOCl
D. Mastrogiuseppe, C. Gazza, A. Dobry
In the present work we aim to characterize the lattice configurations and the magnetic behavior in the incommensurate phase of spin-Peierls systems. This phase emerges when the mag…
Relevance of nonadiabatic effects in TiOCl
Diego Mastrogiuseppe, Ariel Dobry
We analyze the effect of the phonon dynamics on a recently proposed model for the uniform-incommensurate transition seen in TiOX compounds. The study is based on a recently develop…
Theoretical study of the magnetism in the incommensurate phase of TiOCl
D. M. Mastrogiuseppe, M. E. Torio, C. J. Gazza +1
Going beyond a recently proposed microscopic model for the incommensurate transition in the spin-Peierls TiOX (X=Cl, Br) compounds, in the present work we start by studying the the…
