Direct determination of the Tomonaga-Luttinger parameter in quasi-one-dimensional spin systems
Mladen Horvatić, Martin Klanjšek, Edmond Orignac
We test the analytical formula for the enhancement of the nuclear magnetic resonance rate by the critical spin fluctuations, over the simple power-law dependence predict…
Dynamical response and dimensional crossover for spatially anisotropic antiferromagnets
Maxime Dupont, Sylvain Capponi, Nicolas Laflorencie +1
Theoretically challenging, the understanding of the dynamical response in quantum antiferromagnets is of great interest, in particular for both inelastic neutron scattering (INS) a…
Giant magnetic-field dependence of the coupling between spin Tomonaga-Luttinger liquids in BaCo2V2O8
M. Klanjsek, M. Horvatic, S. Kramer +7
We use nuclear magnetic resonance to map the complete low-temperature phase diagram of the antiferromagnetic Ising-like spin-chain system BaCo2V2O8 as a function of the magnetic fi…
Kondo screening by the surface modes of a strong topological insulator
Edmond Orignac, Sébastien Burdin
We consider a magnetic impurity deposited on the surface of a strong topological insulator and interacting with the surface modes by a Kondo exchange interaction. Taking into accou…
Spin-chain system as a tunable simulator of frustrated planar magnetism
M. Klanjsek, M. Horvatic, C. Berthier +5
At low temperatures, weakly coupled spin chains develop a magnetic order that reflects the character of gapless spin fluctuations along the chains. Using nuclear magnetic resonance…
Spectral functions of two-band spinless fermion and single-band spin-1/2 fermion models
Edmond Orignac, Masahisa Tsuchiizu, Yoshikazu Suzumura
We examine zero-temperature one-particle spectral functions for the one-dimensional two-band spinless fermions with different velocities and general forward-scattering interactions…
