Magnetic excitations in the quantum spin ice Yb2Ti2O7
We propose to carry out an inelastic neutron scattering experiment at LET to investigate the excitations in the quantum spin ice Yb2Ti2O7. In contrast to other single crystal... -
Low energy excitations in solid 4He
The atoms in solid helium are weakly bound and have small mass so that the overlap of their wave functions (zero point motion) is large, making it a quantum solid close to the...
