Dynamics of Optically Levitated Microdumbbells
(2021-11-19)
As light carries momentum, enough force can be applied to small particles from a vertical pointing laser to counteract the gravitational force it feels, thus levitating it in thin air. Oblong nanoparticles under these ...
Simulating The Deceleration of Negative Ions in a Quadrupole Beam Guide Using Helium Gas
(2021-11-19)
Attohallen is a new facility, to be set up by the Department of Physics at the University of Gothenburg, that will be used for exploring the temporal evolution of entangled electrons emitted from atoms and molecules using ...
Opto-vibrational coupling in molecular solar thermal storage materials: Electronic structure calculations and neural-networkbased analysis Giannis Kostaras Degree project
(2021-01-26)
Molecular solar thermal storage materials are proposed as a clean, renewable energy
solution for a world with ever increasing energy needs. Norbornadiene is an
organic compound suitable for molecular solar thermal storage ...
Från Liealgebror till rumtidssymmetrier
(2021-11-19)
Kontinuerliga symmetrier är grundläggande inom teoretisk fysik, och beskrivs på ett naturligt sätt via Liegrupper bestående av symmetritransformationer av det underliggande fysikaliska systemet.
Varje sådan grupp svarar ...
Topological Band Theory, An Overview
(2021-06-14)
Topological insulators, superconductors and semi-metals are states of ma er with unique features such as quantized macroscopic observables and robust, gapless edge states. ese states can not be explained
by standard ...
Enkel- och dubbeljonisation av metylisotiocyanat
(2021-11-19)
Metylisotiocyanat (CH3NCS), även kallad MITC, är en biprodukt från jordbruksindustrin. I detta arbete studeras elektronstrukturen och fragmentationsprocessen i CH3NCS vid enkel- och dubbeljonisation med hjälp av en magnetisk ...
Quantum Error Correction Using Graph Neural Networks
(2021-06-17)
A graph neural network (GNN) is constructed and trained with a purpose of using
it as a quantum error correction decoder for depolarized noise on the surface code.
Since associating syndromes on the surface code with ...
Patterns in Interacting Quantum Gases
(2021-11-19)
Quantum gases is a novel field of experimental research, where it is possible to study the universal behaviour of quantum particles under controlled circumstances. In two experiments by Zürn et al. and Holten et al., ...
Styrsystem för en övertonsstrålningskälla optimerad för attosekundsspektroskopi
(2021-11-19)
Ett styrsystem utvecklades för den planerade HHG-uppställning som för närvarande byggs vid Göteborgs universitet, Attohallen. Systemet utvecklades i National Instruments grafiska programmeringsspråk LabVIEW. Styrsystemet ...
