Quantum Magnetism
- Peter Baker (STFC)
Magnetic materials usually undergo magnetic ordering at low temperatures, however, in certain instances they may remain quantum disordered even at zero temperature. Such a case is found in a quantum spin liquid (QSL), a state that is highly entangled, yet it lacks magnetic ordering. QSL states have been experimentally suggested for a variety of geometrically frustrated materials, including...
The search for new states of matter such as quantum spin-liquids involves the characterization of disordered magnetic ground states, and spinons or topological excitations, along with signatures of entanglement. Model examples of these features are found in systems with reduced dimensionality, especially one-dimensional spin chains. I will describe our recent investigations of low-dimensional...
The hole-doped organic superconductor kappa-(ET)4Hg3-dBr8, (k-HgBr), where d=11% and ET=bis(ethylenedithio)tetrathiafulvalene, has been the key to bridge the knowledge gap between half-filled organics and doped cuprate systems. Nonetheless, the isotropic triangular lattice of ET dimers of k-HgBr, organics, unlike the square lattice in cuprates, is suspectedly responsible for its provides...
