Quantum criticality in an organic magnet
(American Physical Society, 2006-06-30)
Exchange interactions between S=½ sites in piperazinium hexachlorodicuprate produce a frustrated bilayer magnet with a singlet ground state. We have determined the field-temperature phase diagram by high field magnetization ...
Condensation of magnons and spinons in a frustrated ladder
(American Physical Society, 2006-06-01)
Motivated by the ever-increasing experimental effort devoted to the properties of frustrated quantum magnets in a magnetic field, we present a careful and detailed theoretical analysis of a one-dimensional version of this ...
