Quantum fluctuations and strong mass renormalization in NiCl2-4SC(NH2)2
Y. Kohama, A. Sologubenko, N. R. Dilley +9
In a number of quantum paramagnets, magnetic field can induce a quantum phase transition to an antiferromagnetic state which exists for a range of fields Hc1 < H < Hc2. Generally,…
Spinon localization in the heat transport of the spin-1/2 ladder compound (CHN)CuBr
A. V. Sologubenko, T. Lorenz, J. A. Mydosh +4
We present experiments on the magnetic field-dependent thermal transport in the spin-1/2 ladder system (CHN)CuBr. The thermal conductivity is only weakly…
Large thermomagnetic effects in weakly disordered Heisenberg chains
E. Shimshoni, D. Rasch, P. Jung +2
The interplay of different scattering mechanisms can lead to novel effects in transport. We show theoretically that the interplay of weak impurity and Umklapp scattering in spin-1/…
Magneto-thermal evidence of a partial gap at the Fermi surface of UPt_2Si_2
N. Johannsen, S. Suellow, A. V. Sologubenko +2
Motivated by the observation of a giant Nernst effect in URu_2Si_2, the thermoelectric response of the related system UPt_2Si_2 was investigated using thermal and electric transpor…
Field-dependent thermal transport in the Haldane chain compound NENP
A. V. Sologubenko, T. Lorenz, J. A. Mydosh +3
We present a study of the magnetic field-dependent thermal transport in the spin S=1 chain material Ni(C2H8N2)2NO2(ClO4) (NENP). The measured thermal conductivity is found to be ve…
Nernst Effect in NdBa_2[Cu_{1-y}Ni_y]_3O_{7-δ}
N. Johannsen, Th. Wolf, A. V. Sologubenko +3
In NdBa_2[Cu_{1-y}Ni_y]_3O_{7-δ}, magnetic Ni-impurities suppress Tc but at the same time the pseudogap is strongly enhanced. This unique feature makes it an ideal system to study…
