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... -
Mapping the Full Magnetic Dispersion of Multiferroic LuFe2O4
A better understanding of the magnetic excitation spectrum of LuFe2O4 is required to refine current models of the magnetoelectric coupling in this novel "electronic"... -
The coupling of spin and charge correlations in La2-xSrxCuO4
Charge density wave (CDW) order has recently been established as a generic feature of high-temperature cuprate superconductors. It occurs near 1/8 doping and has been observed... -
Measurement of q-dependent Joint-DOS of a topological insulator
We propose inelastic neutron scattering (INS) experiment on single crystal of the prototype topological insulator (TI), Bi2Se3, at MAPS to measure q-dependent joint-DOS, based... -

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... -
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...
