Magnetic monopoles in chiral magnets & frustrated magnetism on the swedenborgite lattice

open access: yes, 2015
This thesis deals with magnetic order in condensed matter systems and is divided into three parts. The first part gives a closed and self-contained introduction to the Monte Carlo methods used within this thesis with a special emphasis on a recently ...

Supersymmetry in the Majorana Cooper-pair box

open access: yes, 2014
Over the years, supersymmetric quantum mechanics has evolved from a toy model of high-energy physics to a field of its own. Although various examples of supersymmetric quantum mechanics have been found, systems that have a natural realization are scarce.

Rational design and dynamics of self-propelled colloidal bead chains: from rotators to flagella

open access: yes, 2017
The quest for designing new self-propelled colloids is fuelled by the demand for simple experimental models to study the collective behaviour of their more complex natural counterparts. Most synthetic self-propelled particles move by converting the input

Dynamic phase diagram of dc-pumped magnon condensates

open access: yes, 2014
We study the effects of nonlinear dynamics and damping by phonons on a system of interacting electronically pumped magnons in a ferromagnet. The nonlinear effects are crucial for constructing the dynamic phase diagram, which describes how "swasing" and ...

Quantum simulation of correlated-hopping models with fermions in optical lattices

open access: yes, 2014
By using a modulated magnetic field in a Feshbach resonance for ultracold fermionic atoms in optical lattices, we show that it is possible to engineer a class of models usually referred to as correlated-hopping models.

Phase behaviour of polarizable colloidal hard rods in an external electric field: A simulation study

open access: yes, 2014
We present a double-charge model for the interaction between parallel polarizable hard spherocylinders subject to an external electric field. Using Monte Carlo simulations and free-energy calculations, we predict the phase behaviour for this model as a ...

Relaxation dynamics in the columnar liquid crystal phase of hard platelets

open access: yes, 2011
We perform Monte Carlo simulations to analyze the equilibrium dynamics and the long-time structural relaxation decay of columnar liquid crystals of disk-like colloidal particles.

Nonequilibrium Transport Through Kondo Quantum Dots: A Real-Time Renormalization Group Analysis

open access: yes, 2014
Kondo physics first surfaced into the scientific world in 1934 via an unexpected observations made by a group of experimentalists, who measured the temperature-dependent resistance of gold wires in their laboratory at the University of Leiden.
