Tero Heikkilä

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
