History

Welcome!

In addition to the quantum mechanical properties of electrons such as the wave nature, superposition state, and spin, Quantum Solid State Physics Research Group focuses on many-body effects and correlations that arise from electron-electron interaction. We aim to engineer and control such quantum effects by exploiting heterostructures and nanostructures of semiconductors and 2D materials and thereby realize quantum devices and sensing techniques unattainable with individual electrons.

Topological insulator

Topological insulators are characterized by spin-polarized edge states that have possible applications for spintronics and quantum computation. We engineer an electrically tunable topological insulator using semiconductor heterostructures.

See publications

Graphene plasmonics

For plasmonic applications, graphene has potential advantages owing to its relatively low loss, high confinement, and tunability by external electric field. We study active control of graphene plasmons.

See publications

Fractional quasiparticles

Quasiparticles in fractional quantum Hall states have fractional charge and anyonic statistics. For particular states, they may obey non-Abelian statistics that provide the basis of fault-tolerant quantum computation.

See publications

Quantum-Hall edge state

Quantum-Hall edge states serve as ideal one-dimensional channels where one can study quantum electron optics and many-body physics such as Tomonaga-Luttinger liquid.

See publications

Semiconductor nanowire

We demonstrate a highly gate-tunable spin-orbit interaction in a gate-all-around semiconductor nanowire field-effect transistor.

See publications

Atom manipulation

We use a scanning probe to assemble and characterize artificial nanostructures controlled at atomistic levels.
