Open Topological Field Theories and 2-Segal Objects
Stern, Walker H. (2019-10-17)In this thesis we analyze 2-dimensional open topological field theories in both 1-categorical and ∞-categorical contexts. Making use of the formalism, introduced by Dyckerhoff and Kapranov, of graphs structured over a ... -
Operads, Algebras and Modules in Model Categories and Motives
Spitzweck, Markus (2004)In the first part of this thesis the homotopy theory of operads, algebras over operads and modules over operad algebras is developed in the context of cofibrantly generated symmetric monoidal model categories. It is shown ... -
Optical cleaning of lithium niobate crystals
Kösters, Michael (2010-03-04)An all-optical method for the removal of photoexcitable electrons from photorefractive centers to get rid of optical damage in lithium niobate crystals is presented, the so-called "optical cleaning". The method combines ... -
Optical confirmation and weak lensing mass constraints for distant Sunyaev-Zel'dovich-detected galaxy clusters
Zohren, Hannah (2022-03-28)Galaxy clusters reside in the densest regions of the large-scale matter distribution of the Universe. Therefore, their number density as a function of mass and redshift is a powerful tool for cosmological studies aiming, ... -
Optical control of single neutral atoms
Alt, Wolfgang (2004)This thesis presents experiments concerning the preparation and manipulation of single neutral atoms in optical traps. The experimental setup as well as the properties of the optical dipole trap are described. The examination ... -
Optical Data Analysis and its Application to Cosmology
Buddendiek, Axel (2016-03-30)This work is concerned with different aspects of observational cosmology. It covers a broad range of problems that one needs to deal with in optical astronomy.
Three introduction chapters about cosmology, gravitational ... -
Optical investigations on PTCDA on KCl(100): Superradiant aggregates and single molecules
Marquardt, Christian (2019-08-23)In the present work, condensed and diluted phases of 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) were investigated on thin KCl(100) films on the Ag(100) surface. The samples were structurally characterized by spot ... -
Optical investigations on rubrene in the condensed state
Krylova, Olga (2013-08-13)The incomplete understanding of the optical properties of rubrene, a material with a promising potential for future application in organic devices, inspired the present study. The main goal of the present investigations ... -
Optical plane selection in a dipole trap
Winkelmann, Falk-Richard Gerhard Heinz (2021-12-17)Quantum technology has advanced considerably within the last decades [1, 2]. Quantum simulators are among the primary goals of this ongoing „quantum revolution“ [3]. They promise insight into many-particle phenomena that ... -
Optical spectroscopy and applications of atomically precise graphene nanoribbons: from light emission to photodetection
Alavi Eshkaftaki, Seyed Khalil (2020-11-16)Atomically precise graphene nanoribbons (GNRs) are narrow stripes of graphene with a width of a few atoms and a well-defined edge structure. On-surface synthesis of GNRs from molecular precursors enables atomic precision ... -
The Optical System and the Astronomical Potential of A-MKID, a New Camera Using Microwave Kinetic Inductance Detector Technology
Esteras Otal, Luis (2015-11-25)In the framework of sub-millimeter astronomy, the need to create more efficient cameras with more pixels, with larger FoV and with higher mapping speed is highly desirable. In order to satisfy this necessity a new camera ... -
Optimal Control of Quasilinear Parabolic PDEs: Theory and Numerics
Hoppe, Fabian (2022-12-15)This thesis is concerned with theory and numerics of optimal control of quasilinear parabolic PDEs. The underlying parabolic PDE models, e.g., heat conduction with temperature-dependent thermal conductivity and is highly ... -
Optimal Numerical Basis Functions in the Partition of Unity Method
Düsseldorf, Denis Alexander (2024-04-08)Partial differential equations (PDE) arise from the modeling of a wide range of physical problems and knowing how to solve them is of large interest in many industrial undertakings. One numerical method to solve PDE is the ... -
Optimal quantum control of atomic wave packets in optical lattices
Peter, Natalie (2019-05-24)In this work, I investigate the motional control and the transport of single neutral atoms trapped in an optical conveyor belt. The main goal is to prepare the atoms in the vibrational ground state of the trapping potential ... -
Optimal transport and geometric analysis in Heisenberg groups
Juillet, Nicolas (2009-01-29)In this thesis we consider the Heisenberg group H_n=R^{2n+1} with its Carnot-Carathéodory distance d_c and the Lebesgue measure L^{2n+1}. In Chapter 1, in relation with the geometric traveling salesman problem in H_1, we ... -
