Stochastic modelling of new phenomena in financial markets
… Financial Crisis (GFC) has revealed a number of new phenomena in financial markets, to which stochastic models have to be adapted. This dissertation presents two new methodologies, one for modeling the “basis spread”, and the other for “rough volatility”. The former gained prominence during the …

Search for new phenomena using three-photon final states in data collected with the ATLAS detector at the Large Hadron Collider
<p>This thesis presents a search for new phenomena using three high-$p_T$ photons in the final state. In some Beyond the Standard Model (BSM) theories, a vector boson, $Z^\prime$, can decay to a pseudoscalar, $a$, and a photon, $\gamma$. The pseudoscalar can then decay into two photons: $Z^\prime …

Two leptons, jets, and missing transverse momentum in ATLAS: yet more non-evidence for supersymmetry
Searching for new phenomena is an essential endeavour of experimental physics, and is helped by guidance from plausible theoretical predictions. This thesis presents such a search for signals of high-energy protons scattering to massive resonances with dramatic decays, which are predicted by …

Quantitative mapping of nanothermal transport via Scanning Thermal Microscopy
… nanoscience and nanotechnology create new challenges to understand materials behaviour at the nanometre length scales. New phenomena require matching tools that in turn open new investigation perspectives, themselves launching platforms for new discoveries. Amongst the vast realm of …

Suche nach Kontakt-Wechselwirkungen und Gravitoneffekten in der tief-inelastischen Streuung bei HERA
… standard model expectation shows no evidence for new phenomena. Therefore exclusion limits are derived for the mentioned physical scenarios beyond the standard model. The combination of all data sets leads to maximum sensitivity and significantly improved limits compared to earlier results of H1.

Asymptotic analysis of extreme electrochemical transport
… currently outpaces theoretical understanding of new phenomena. Classical electrochemical transport theory is not equipped to explain the behavior of electrochemical systems in the extreme operating conditions required by modern devices. In this thesis, we extend the classical theory to examine …

Nonlinear transport in two-dimensional electron gas at large filling factors.
… discovered in microwave-irradiated 2DEG. New phenomena in magnetotransport emerged when a 2DEG was under the simultaneous influences of a dc electric field and a microwave field. The experimental observations were compared to the numerical simulations which were carried out based on a …

Visualization of the Vortex Lattice Dynamics in Superfluid Helium
… vortices in superfluid helium-4 using a new rotating experiment. This setup includes control of the entire apparatus from the rotating frame, installation of a new EMCCD camera that allows for imaging of nanoscale tracer particles, and the development and implementation of a new isolation …

Statistical imaging of transport in complex fluids: a journey from entangled polymers to living cells
… mechanics, we studied several transport phenomena in complex fluids with nanometer and millisecond resolution. On the list are diffusion of nanoparticles and vesicles in crowded environments, reptational motion of polymers in entangled semidilute solutions, and active endosome transport …

Phenomenology of new physics beyond the Standard Model: signals of Supersymmetry with displaced vertices and an extended Higgs sector at colliders
… our ignorance into focus by showing us there are new phenomena that we can not describe within the framework of the SM. These include the experimental observations of neutrino masses and dark matter, which confirms there must be new physics. What this new physics may look like at colliders …

Property and valuation methods in new media: an examination of existing theories and practices and their applicability to new media ventures
New media has become a major part of our daily routine and influences both our social interactions and the ways in which we conduct business. Not only does it provide new business tools to existing business models, it has also created a platform from which new forms of commerce and exchange can …

Fourth order spectral theory and diffusion-driven instability

Advanced engineered substrates for the integration of lattice-mismatched materials with silicon
… buffers on Si (i.e. Vx[Si1-xGex]/Si). Several new phenomena in relaxed graded SiGe buffers are developed in this thesis. A rise in threading dislocation density was observed in high-Ge content relaxed graded SiGe layers grown at relatively high temperatures, which was attributed to dislocation …

Elastic and inelastic dipolar scattering
… physicists can build complex systems that show new phenomena. Most of those emerging phenomena arise from interactions. The strength of the interactions is an essential parameter for a quantum gas experiment. If the interactions are too weak or lead to rapid losses, the experiment cannot …
