Quantum phase transition study through developing new high-pressure devices
In this program, we offer the opportunity to discover a novel quantum phases in novel quantum magnetism compounds, which are produced by the interplay between the relativistic spin-orbit coupling, electron correlations and lattice symmetry. Our play ground is compounds with heavy transition metal elements, where the relativistic strong spin-orbit coupling is extremely as large as 1 eV and close to the bandwidth and the Coulomb repulsion.
The example of our target is a spin-orbit entangled liquid state, where exotic quasiparticles such as Majorana fermions may be anticipated. Such topological magnetic phases have been difficult to be observed especially at high pressures. We are aiming materialization and realization of such new states through developing state-of-the-art high-pressure devices for magnetometry and NMR.
