Torque field and skyrmion motion by spin transfer torque in a quasi-2D interface in presence of strong spin-orbit interaction KU Leuven University of Antwerp
Voltage-controlled phase slips for superconducting quantum devices KU Leuven
Quantum computers promise to execute certain tasks exponentially faster than classical computers. A fundamental challenge for upscaling quantum computers is the volatility of their building blocks—namely, qubits. For example, superconducting qubits require an external magnetic flux bias to tune their frequency, making them prone to dephasing via low-frequency flux noise. This thesis proposes an alternative platform for superconducting qubits ...

Energy filtering in silicon nanowires and nanosheets using a geometric superlattice and its use for steep-slope transistors KU Leuven University of Antwerp
© 2018 Author(s). This paper investigates energy filtering in silicon nanowires and nanosheets by resonant electron tunneling through a geometric superlattice. A geometric superlattice is any kind of periodic geometric feature along the transport direction of the nanowire or nanosheet. Multivalley quantum-transport simulations are used to demonstrate the manifestation of minibands and minibandgaps in the transmission spectra of such a ...
Anisotropic bulk and planar Heisenberg ferromagnets in uniform, arbitrarily oriented magnetic fields KU Leuven University of Antwerp
Today, further downscaling of mobile electronic devices poses serious problems, such as energy consumption and local heat dissipation. In this context, spin wave majority gates made of very thin ferromagnetic films may offer a viable alternative. However, similar downscaling of magnetic thin films eventually enforces the latter to operate as quasi-2D magnets, the magnetic properties of which are not yet fully understood, especially those related ...
Flux Quantization and Aharonov-Bohm Effect in Superconducting Rings KU Leuven University of Antwerp
© 2017, Springer Science+Business Media, LLC. Superconductivity is a macroscopic coherent state exhibiting various quantum phenomena such as magnetic flux quantization. When a superconducting ring is placed in a magnetic field, a current flows to expel the field from the ring and to ensure that the enclosed flux is an integer multiple of h/(2|e|). Although the quantization of magnetic flux in ring structures is extensively studied in literature, ...
Spin-based majority computation KU Leuven
© Springer International Publishing AG, part of Springer Nature 2019. The downscaling of Complementary Metal Oxide Semiconductor (CMOS) devices will come to an end in the following decade. This has accelerated research that explores new device concepts that can help the semiconductor industry move forward, beyond the CMOS roadmap. Such device concepts include spin-based technologies which have a propensity to low-energy operation and ...
