I am a condensed matter theorist with expertise and interested towards quantum properties of materials and devices. I am in particular interested in the following topics:
- Flat-band superconductivity - I participate in the SuperC2033 consortium (superc2033.com)
- Nonequilibrium and inhomogeneous superconductivity
- Superconductor/ferromagnet heterostructures, superconducting spintronics
- Topological media, especially topological semimetals, nodal line semimetals
- Dynamic properties of quantum matter
- Open quantum systems
- Optomechanics and magnomechanics
- Heat transport and thermoelectricity in mesoscopic electron systems; fluctuation theorems
- Josephson diodes and non-reciprocal transport
- Spin and orbital Hall effects and torque; kinetic theory in multiband systems
We use various theory techniques in these projects - whatever is needed for the precise problem at hand. In particular, I have experience in using these techniques:
- Keldysh Green's functions and real-time quantum kinetic theory
- Quasiclassical theory of superconductivity
- Path integrals for real-time phenomena: in particular, for fluctuations and collective modes
- Scattering theory
- Methods for open quantum systems: quantum master equations, input/output equations, quantum jump methods
- Different types of tight binding lattice models
I participate in different research consortia. For example
- SuperC collaboration (superc2033.com)
- JoGate H2020 project, due to start in Dec 2023
- Finnish Quantum Flagship, due to start in 2024
