Research Topics

TNTL studies electron transport in nanoscale systems theoretically with emphasis on spin related effects.

General research interest may be summarized as follows. 
  • Spin polarized transport
    • Spin transfer torque 
    • Spin motive force
    • Spin-orbit coupling effects
  • Quantum coherent transport and electron correlations 
    • Quantum interferometer in low dimensional systems
    • Luttinger liquid behaviors in quantum wires
Ongoing research activities are focused on
  • Spin-orbit coupling effects on spintronics
    • Spin-orbit coupling effects at heterojunction interfaces
    • Roles of atomic orbital degree of freedom for spin-orbit coupling effects
    • Spin-orbit coupling effects on antiferromagnet spintronics
    • Topological insulator-ferromagnet heterostructures
    • Chiral dissipation
Possible future topics of interest (for new TNTL members) include
  • Magnon spintronics
  • Spintronics in 2D materials (van der Waals materials such as WSe2)
  • Weyl semimetal spintronics
