Field dependent mass enhancement in Pr_{1-x}La_xOs_4Sb_12 from aspherical Coulomb scattering
G. Zwicknagl, P. Thalmeier, P. Fulde
The scattering of conduction electrons by crystalline electric field (CEF) excitations may enhance their effective quasiparticle mass similar to scattering from phonons. A wellknow…
Theory of Spin Exciton in the Kondo Semiconductor
Alireza Akbari, Peter Thalmeier, Peter Fulde
The Kondo semiconductor exhibits a spin and charge gap of approximately 15 meV. Close to the gap energy narrow dispersive collective excitations were identified by prev…
Spin fluctuations probed by NMR in paramagnetic spinel LiVO: a self-consistent renormalization theory
V. Yushankhai, T. Takimoto, P. Thalmeier
Low frequency spin fluctuation dynamics in paramagnetic spinel LiVO, a rare 3-electron heavy fermion system, is investigated. A parametrized self-consistent renormalizat…
Self-consistent renormalization theory of spin fluctuations in paramagnetic spinel LiV2O4
V. Yushankhai, P. Thalmeier, T. Takimoto
A phenomenological description for the dynamical spin susceptibility observed in inelastic neutron scattering measurements on powder samples of LiVO is dev…
Green's function approach to quantum criticality in the anisotropic Kondo-necklace model
H. Rezania, A. Langari, P. Thalmeier
We have studied the quantum phase transition between the antiferromagnetic and spin liquid phase for the two dimensional anisotropic Kondo-necklace model. The bond operator formali…
Quantum fluctuations in high field magnetization of 2D square lattice J1-J2 antiferromagnets
P. Thalmeier, M. E. Zhitomirsky, B. Schmidt +1
The J1-J2 square lattice Heisenberg model with spin S=1/2 has three phases with long-range magnetic order and two unconventionally ordered phases depending on the ratio of exchange…
