The motivation is to derive theoretical predictions for temperature measurements of a quantum integrated circuit. These mesurements are the goal of a planned experiment to be conducted in Jukka Pekola's lab at Aalto. The talk is based on papers in collaboration with Brecht Donvil, Antti Kupiainen, Jukka Pekola, and Kay Schwieger. - - - - - 05.03.2020 Jouko Nieminen: "2D Materials for Quantum Technologies" 2-dimensional and layered materials, such as transition metal dichalcogenides (TMD) provide a promising platform for developing components for novel semiconductor–superconductor hybrid devices, such as sensors, switches, qubits and logical components in nanometer-scale electronics. Especially edges and interfaces lead to tunable electronic properties, which can be utilized in, e.g, control of spin polarized currents or proximity induced superconductivity in semimetallic or semiconducting heterostructures. In modeling appropriate materials, we utilize Nambu-Gorkov Green’s function approach in materials specific tight-binding basis, which allow controlled inclusion of, e.g., Hamiltonian matrix elements for spin-orbit coupling or superconducting pairing, as well as coupling to bosonic modes in form of self-energies in Dyson’s equation.
