In this program, we offer the opportunity to discover a novel quantum phases in heavy transition metal 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.

Another example includes 3D Dirac electrons, where the relativistic electronic Hamiltonian determines motions.

We are aiming the materialization and the detection of such new states by employing for example advanced synthesis technique, pulsed-laser-deposition thin-film fabrication and nuclear magnetic resonance under ultrahigh-pressures.
