Search for Higgs Boson Pair Production in the bb̅τ+τ- Final State with the ATLAS Experiment at the LHC
(2023-12-18)
A search for Higgs boson pair (HH) production in final states with two b quarks and two τ leptons using 139 fb-1 of proton–proton collision data at a centre-of-mass energy of 13 TeV recorded ...
Stability of dynamics and memory in the balanced state
(2023-01-17)
Computational modeling of neural circuits has successfully explained the observed irregular and asynchronous activity in the brain as the result of a dynamical balance of excitatory and inhibitory inputs to individual ...
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 ......
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 ...
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 ...
Non-Reversible Markov-Chain Monte Carlo: Theoretical Foundations and Applications in Molecular Simulation
(2024-01-29)
The overarching objective of this doctoral thesis is the development of a rigorous paradigm for molecular simulation based on non-reversible Markov-chain Monte Carlo (MCMC) algorithms. The numerical exploration of the ......
Pulsar Scintillation and Interstellar Lenses
(2024-01-29)
The radio emission of pulsars is scattered within the interstellar medium due to variations of the electron column density. Pulsars are very compact sources of pulsed radiation and, thus, emit spatially coherent radiation ...
Characterizing Time-Evolving Functional Networks
(2024-01-10)
Understanding spatially-extended, complex dynamical systems is a vital task in the natural sciences. From the climate over eco-socio-cultural systems to the human brain, time-evolving complex systems abound. These systems ...
The formation mechanisms of classical emission line stars
(2023-10-10)
Classical emission line stars are known fast rotators hosting a decretion disc in which emission lines are formed. Since their discovery in 1866, the formation mechanism of this class of stars has proved difficult to ...
