Mistaken eyewitness identifications continue to be a major contributor to miscarriages of justice. Previous experiments suggested that implicit identification procedures such as...

One of the major issues in high temperature superconductivity is the nature of the so called pseudogap phase. A related question is whether the pseudogap controls the evolution...

Exchange interactions in insulators can be understood in terms of the Andersen exchange picture in which the Hamiltonian has two contributions: (i) a kinetic term characterized...

We have recently succeeded in measuring the excitation spectrum of charge doped cuprate chains with a 90 degree Cu-O-Cu bonding geometry. This study resolved a long standing...

Iron is a canonical instance of an itinerant electron ferromagnet, and a classic correlated electron system. Our recent data from MAPS contradicts earlier triple-axis data that...

CePd3 is a classic intermediate valence (IV) system. In MAPS experiment 620167 we obtained an important qualitative result for CePd3, namely that the Kondo-like scattering...

CrB2, like MnB2, are transition metal diborides that have magnetically ordered ground states. Preliminary neutron (TAS) work and in house lab indicated that the dispersion has...

In our recent experiments on MERLIN we have established that the spin excitations in Fe(Se,Te) emanating from incommensurate positions near (0.5 0.5 0) extends at least to 250...

The recent discovery of the iron arsenide family of layered superconductors RFeAsO1-xFx and AFe2As2 with transition temperature up to 52K has generated tremendous interest as...

The proposal aims to further investigate the transition from commensurate magnetic order to incommensurate magnetic and charge stripe order in the family of compounds,...

The unique "hourglass"-type dispersion observed within several classes of hole-doped cuprates has garnered considerable theoretical and experimental interest. Here we propose to...
