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 ...
Excitation and Detection of Spinwaves with Light
(2020-07-03)
Spinwaves (SWs) are a collective excitation of the local spin moments in a magnetic
ordered medium. Spinwaves can be excited electrically using microwave
sources, direct currents, and by focused optical short pulses on ...
Characterizing CEPA, a phoswich array
(2019-08-01)
The structure of unstable nuclei is studied at the international facility FAIR, Darmstadt,
Germany. One experimental setup at FAIR is called R3B where radioactive beams at relativistic energies impinge on a specific target ...
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 ...
Studies on the spatial resolution in magnetoencephalography
(2020-08-05)
Functional neuroimaging is used in research and clinical settings to understand how the brain works when it is healthy and how to treat it when it is not. Magnetoencephalography (MEG) is a functional neuroimaging method ...
Single-photon double ionisation of Isocyanic acid
(2019-06-26)
Isocyanic acid (HNCO), a molecule containing the four most abundant atoms of organic chemistry, has been studied by single-photon double ionisation. Both direct double ionisation, such as core-valence and valence-valence ...
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 ...
Enfoton-dubbeljonisation av isothiocyansyra
(2020-07-03)
Isotiocyansyra, HNCS, en interstellärt intressant molekyl har studerats genom att
använda flygtidsspektroskopi med en magnetisk flaska, där molekylen joniseras med
enstaka fotoner med energier upp till 195 eV. En redogörelse ...
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 ...
