Field induced magnetic ordering transition in Kondo insulators
I. Milat, F. F. Assaad, M. Sigrist
We study the 2D Kondo insulators in a uniform magnetic field using quantum Monte Carlo simulations of the particle-hole symmetric Kondo lattice model and a mean field analysis of t…
Superconductivty without inversion symmetry: MnSi versus CePt_3Si
P. Frigeri, D. F. Agterberg, A. Koga +1
Superconductivity in materials without spatial inversion symmetry is studied. We show that in contrast to common believe, spin-triplet pairing is not entirely excluded in such syst…
Field- and pressure-induced magnetic quantum phase transitions in TlCuCl_3
M. Matsumoto, B. Normand, T. M. Rice +1
Thallium copper chloride is a quantum spin liquid of S = 1/2 Cu^2+ dimers. Interdimer superexchange interactions give a three-dimensional magnon dispersion and a spin gap significa…
Heavy fermion superconductivity and magnetic order in non-centrosymmetric
E. Bauer, G. Hilscher, H. Michor +7
is a novel heavy fermion superconductor, crystallising in the structure as a tetragonally distorted low symmetry variant of the structure…
