Quantum critical dynamics in the presence of disorder
Quantum phase transitions are abrupt qualitative changes of a system's groundstate occurring only at exactly zero temperature. Such critical points - although never reachable... -

Cu-ion mobility and lattice dynamics in the liquid-like phase of Cu2Se
Thermoelectricity enables the conversion of waste heat into useful power, and it is becoming increasingly important for power recovery applications at high temperature, where... -
Low energy spin dynamics of the stoichiometric heavy fermion CeRuSn3
Heavy fermion systems situated close to a quantum critical point present very rich physics due to the dominant Kondo interactions. Our investigations on the Kondo lattice heavy... -
Magnetic inelastic scattering from dimethylammonium metal formates
The dimethylammonium metal formates (metal = Mn, Fe, Co, Ni) are metal-organic perovskite analogues of interest for potential multiferroicity. In these materials, electric... -
E/T scaling and quantum critical fluctuations in Sr3Ru2O7
Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature.... -
Non-magnetic impurities in a strong-leg spin ladder
Th S = ½ AF spin ladder is one of the most important models in quantum magnetism. While its properties throughout the (H,T)-phase diagram may be considered to be well understood...
