Double-Fourier engineering of Josephson energy-phase relationships applied to diodes

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: A. Mert Bozkurt, Jasper Brookman, Valla Fatemi, Anton R. Akhmerov, | Summary: We present a systematic method to design arbitrary energy-phase relations using parallel arms of two series Josephson tunnel junctions each. Our approach employs Fourier engineering in the energy-phase relation of each arm and the […]

Design of a Majorana trijunction

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Juan Daniel Torres Luna, Sathish R. Kuppuswamy, Anton R. Akhmerov, , | Summary: Braiding of Majorana states demonstrates their non-Abelian exchange statistics. One implementation of braiding requires control of the pairwise couplings between all Majorana states in a trijunction device. In order to have adiabaticity, a […]

Optimality in superselective surface binding by multivalent DNA nanostars

Kavli Affiliate: Jos Zwanikken | First 5 Authors: Christine Linne, Eva Heemskerk, Jos Zwanikken, Daniela J. Kraft, Liedewij Laan | Summary: Weak multivalent interactions govern a large variety of biological processes like cell-cell adhesion and virus-host interactions. These systems distinguish sharply between surfaces based on receptor density, known as superselectivity. Earlier experimental and theoretical work […]
