Reducing disorder in Ge quantum wells by using thick SiGe barriers

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Davide Costa, Lucas E. A. Stehouwer, Yi Huang, Sara Martí-Sánchez, Davide Degli Esposti | Summary: We investigate the disorder properties of two-dimensional hole gases in Ge/SiGe heterostructures grown on Ge wafers, using thick SiGe barriers to mitigate the influence of the semiconductor-dielectric interface. Across several heterostructure field […]

Nonlinearity of transparent SNS weak links decreases sharply with length

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Valla Fatemi, Pavel D. Kurilovich, Anton R. Akhmerov, Bernard van Heck, | Summary: Superconductor-normal material-superconductor (SNS) junctions are being integrated into microwave circuits for fundamental and applied research goals. The short junction limit is a common simplifying assumption for experiments with SNS junctions, but this limit […]

Edge and bulk states in a three-site Kitaev chain

Kavli Affiliate: Michael Wimmer | First 5 Authors: Sebastiaan L. D. ten Haaf, Yining Zhang, Qingzhen Wang, Alberto Bordin, Chun-Xiao Liu | Summary: A chain of quantum dots (QDs) coupled via semiconductor-superconductor hybrid regions can form an artificial Kitaev chain hosting Majorana bound states (MBSs). These zero-energy states are expected to be localised on the […]

Quantum resources of quantum and classical variational methods

Kavli Affiliate: Eliska Greplova | First 5 Authors: Thomas Spriggs, Arash Ahmadi, Bokai Chen, Eliska Greplova, | Summary: Variational techniques have long been at the heart of atomic, solid-state, and many-body physics. They have recently extended to quantum and classical machine learning, providing a basis for representing quantum states via neural networks. These methods generally […]
