Magnon-Plasmon Polaritons: New Solid-State Quasiparticles
Host Institute: Institute of High Pressure Physics, Polish Academy of Sciences
Principal investigator: dr. Marcin Białek
Realization dates: 2024-04-02 - 2029-04-01
Financing: 4 258 760 PLN
The leading goal of the Spin-2-Plasm project is to demonstrate and explore the functionalities of a new type of low-energy excitations: hybrid magnon-plasmon modes. Such quasiparticles will allow electrical control and readout of magnetic states with terahertz (THz) frequencies, which is necessary for ultrafast communications, memories, and other technologies. Current research in two-dimensional antiferromagnetic (2DAFM) materials offers an unprecedented possibility to show such a coupling, using magnons in 2DAFMs and plasmons in two-dimensional electron gas (2DEG). This is possible because both excitations have resonant frequencies in the same range of terahertz (THz) frequencies. This effect could be observed in heterostructures of high electron mobility 2DEG interfaced with 2DAFMs, as predicted theoretically. We also set out to achieve magnon-plasmon coupling by using a mediating electromagnetic cavity mode.
