Flór, Ian Matthias (author)The detection of nonAbelian exchange statistics is an open challenge which holds important promises for the advent of topological quantum computation. A recent work proposes to rely on the edges to reveal the braiding statistics of nonAbelian anyons in the bulk, in an entirely deterministic dynamical process. A timedependent gap in a Josephson...master thesis 2023

Claes, Joep (author)Random walks have been applied in a many different fields for a long time. More recently, classical random walks are being used in wide variety of computer algorithms used to solve complex computational problems like 2SAT, 3SAT and the estimation of the volume of complex bodies. In this thesis we look into the quantum version of the familiar...bachelor thesis 2022

Brookman, Jasper (author)Conventional semiconductor diodes dissipate energy in the form of heat when current passes through them. This is unwanted in, for example, cryogenic environments. Using a superconducting diode could mitigate this problem. These have been made by using special materials or combining multiple different circuit elements. We provide a systematic...bachelor thesis 2022

Draškić, Radoica (author)Superconducting quantum circuits came out as promising candidates for the exploration of topological phenomena that are currently inaccessible in condensed<br/>matter systems. One such circuit is a Cooper pair transistor which has already<br/>been widely studied in different regimes of operation due to its importance in<br/>quantum computation....master thesis 2021

Bouma, Jort (author)In this work we investigate neural networks and subsequently physicsinformed neural networks. Physicsinformed neural networks are away to solve physical models that are based on differential equations by using a neural network. The wave equation, Burgers’ equation, Euler’s equation, and the ideal magnetohydrodynamic equations are introduced and...bachelor thesis 2020

de Groot, J.J.A.M. (author)This thesis gives a thorough description of the mathematical tool called reflection positivity, which can be used to prove the occurrence of phase transitions in physical models. A major result, although already known, is a theorem that gives tractable conditions on the Hamiltonian such that the Boltzmann functional is reflection positive. In...bachelor thesis 2020

Benedysiuk, Piotr (author)The electrostatics has effect on conductance of nanowire devices. In this model electrostatics are described by nonlinear coupling of the Poisson and the Schr¨odinger equations. In presence of magnetic and electric field and spinorbit interaction, conductance develops a feature called the helical gap. This gap is characterised by a drop of...bachelor thesis 2019

ter Hoeven, R.S. (author)The Kernel Polynomial Method (KPM) is a method to approximate any function as a polynomial of finite order. In this research the KPM will be used to approximate the density of states and expectation values of physical observables in a tight binding system. To be able to use the KPM a tight binding Hamiltonian is obtained by using the python...bachelor thesis 2016

Hortensius, J. (author)In transmon qubits, the leading source of errors for quantum gates is the existence of higher energy levels, besides the 0> and 1> states which form the computational subspace. Several methods have been developed to eliminate these errors systematically by clever use of the available experimental controls. In this bachelor thesis we focus on...bachelor thesis 2015

Markensteijn, A. (author)Four iterative methods were used to solve the schrödinger equation on a rectangular scattering region with a uniform potential, namely GMRES, restarted GMRES, BiCGStab and IDR(s). A preconditioner like a shiftedLaplacian is tried to improve the convergence behaviour of GMRES. Finally, a disorded potential is introduced in the form of a random...bachelor thesis 2014
