Doping-induced energy gap in a quantum spin chain
SrCuO2 is a prototypical S = 1/2 antiferromagnetic (AF) Heisenberg 1D spin chain system. High-resolution neutron scattering studies has already successfully revealed the gapless... -
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...
