Superconducting Bolometer upon a 3D Nanohelix

Bolometers detect electromagnetic radiation by measuring the temperature rise as the photons are absorbed into the sensor. This project aims to design a microwave bolometer upon a superconductor 3D nanohelix, which has a giant thermal voltage response due to a sharp superconducting transition.

Microwave Resonator on Fractional Flux Quanta

The superconducting magnetic flux quantum Ф₀ = h/(2e) is a combination of the fundamental constants: the Planck constant h and the electron charge e. However, in two-band materials, a vortex with Ф₀ can dissociate into fractional components Ф₁ + Ф₂ = Ф₀. This project aims to design a superconducting resonator based on the vortex dissociation in the GHz frequency range.

Probes for Cryogenic Quantum Electronic Devices

Solid-state quantum electronic devices are operated at cryogenic temperatures, in external magnetic fields and in a broad frequency range from DC to, typically, 70 GHz. This project aims to design and test sample probe platforms and PCBs for measurements at room temperature and under cryogenic conditions.

Microwave Antennas for Spin-Wave Excitation

Spin waves and their quanta – magnons – are collective precessions of spins in a magnetically ordered medium. Their interfacing with conventional electronics requires the use of microwave antennas. This project aims to design and test the efficiency of planar antennas for spin-wave generation and detection.

Superconducting Electronics via COMSOL Modeling

A ﬁnite element solver COMSOL enables modeling tasks for superconducting electronics and elevates the results to the level of animation. This project aims to apply established theoretical frameworks to model the electromagnetic properties of superconductors and design cryogenic electronic devices.

Electrical Probing of Magnetic 3D Nanoarchitectures

Additive nanotechnology (e.g., nanoprinting) enables complex-shaped magnetic 3D architectures with diverse magnetic textures. This project aims to model the magnetic configurations of 3D nanoarchitectures and to probe their state via magneto-resistance measurements.
