Quantum Simulation of the Periodic Quantum Rabi Model at Deep Strong Coupling
(2024-01-16)
The quantum Rabi model (QRM) stands as perhaps the most fundamental framework describing qubit-light interaction. While observations of many experiments can already be described within the Jaynes-Cummings model, which ...
Determination of |Vcb| and form factors of B̄0 → D*+ℓ−ν̄ℓ decays with Belle II data
(2024-01-11)
This thesis presents a determination of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element magnitude |Vcb| and form-factor parameters of B̄0 → D*+ℓ−ν̄ℓ decays, where ......
Katalytische Reaktionen auf VO2-Polymorph Oberflächen unter Ausnutzung des Phasenübergangs
(2024-01-17)
Aufgrund des wachsenden Energiebedarfs der Menschheit werden energieeffizientere und neuartige Verfahren zur Herstellung von chemischen Grundstoffen mithilfe von Katalyse gesucht. Fluktuierende Reaktionsbedingungen werden ...
Pentaquark Search in Λ0b → Λ+c D D*0K- Decays and LHCb Open Data Release
(2024-01-08)
This PhD thesis reports results of the physics analysis focused on the search of pentaquarks in Lb->LcDstK decays. Pentaquarks were first reported in 2015 by the LHCb collaboration in jpsi proton system. After collecting ...
Functional morphology of an adaptive radiation – sailfin silversides from Sulawesi as a model system
(2024-01-11)
The adaptive fish radiation of sailfin silversides from Sulawesi serves as a model system for studying adaptive divergence. The phylogenetic lineage of “roundfins” is endemic to ancient Lake Matano and is composed of three ......
Spectroscopy of Xenon and Xenon-Noble Gas Mixtures for Bose-Einstein Condensation of Vacuum-Ultraviolet Photons
(2024-01-03)
Bose-Einstein condensation of photons has first been observed in 2010 by the group of Martin Weitz in Bonn. In the experimental scheme, a photon gas is confined to a wavelength-size microcavity filled with a liquid dye ...
Improved Approximation Algorithms for Weighted k-Set Packing
(2024-01-16)
We study the weighted k-Set Packing problem, which is defined as follows: The input consists of a finite collection S of non-empty sets, each of cardinality at most k, as well as a positive weight for each of the sets. The ...
pH Regulation in Human Sperm
(2024-01-18)
In the female reproductive tract, sperm undergo a maturation process, called capacitation, which enables sperm to fertilize the oocyte. The complex cellular mechanisms underlying capacitation are not well understood. Besides ...
Functional characterization of Gαi/s proteins and modulation of their activity by linear and cyclic peptides
(2024-01-30)
Heterotrimeric Gαβγ (guanine nucleotide-binding) proteins serve as molecular switches to activate (“switch on”) or inactivate (“switch off”) diverse intracellular signaling cascades in response to stimulated G protein-coupled ...
