This thesis examines the behavior of a single-qubit quantum system controlled by feedback. Key parameters such as coupling strength, dissipation, and detuning are explored to improve quantum coherence and stability. Based on the results, practical methods for controlling quantum systems are proposed to better understand quantum control techniques and then improve the performance and stability of q
Quantum communication has been widely used as an important component in many applications of quantum information science. It is naturally utilised in the fields of quantum optics and photonics. Quantum communication and quantum cryptography have been studied as a popular subject in research for many years. However, most of the quantum-communication devices are oversized and non-portable. This prob
In order to understand and manipulate biological function at the molecular level, access to high-resolution structures of biological macromolecules is essential, as structure is intimately linked to function. The two main experimental techniques that can achieve atomic, or near-atomic, resolution are crystallography and electron microscopy. Unfortunately, the experimental data alone is typically n
The interaction of extreme ultraviolet light with matter can lead to the emission of an electron in a process known as photoionization. The electron wavepacket (EWP) created in the continuum propagates on the ionic potential, resulting in a delay compared to an EWP propagating freely. The development of extreme ultraviolet attosecond light sources in recent years has opened the possibility to prob
Öresund is a very dynamic economic area with numerous projects, there is a great need of a deeper understanding of the wave climate. The wave measurements currently available are scarce and they do not cover the whole area. For this reason, a modeled wave climate would be of interest and the results could be a starting point for different in depth analysis. The objective of this study was to prod
A network of communicating wireless devices that are implantable, wearable or within close proximity of a human body is called wireless body area network (WBAN). The propagation channels for the devices in the WBAN are either through the body or over the body. This results in the attenuation and the absorption of electromagnetic waves radiated by the antenna of these devices due to the lossy tissu
Popular Abstract in Swedish Anpassningen av geofysiska metoder till infrastrukturtillämpningar är en viktig del i utvecklingen av geoteknisk förundersökningsmetodik. Det som här benämns geotekniska förundersökningar hänvisar till alla undersökningar som görs före eller under konstruktion, alltså sådana som syftar till att stödja och förbättra en konceptuell geologisk modell så väl som sådana som sThe adaptation of geophysical methods for civil engineering purposes represents an important contribution to the development of geotechnical site investigation methodology. The term geotechnical site investigation here refers to all investigations performed prior to or during construction; i.e. investigations to support and refine a conceptual geological model as well as to provide a model of geot
Popular Abstract in Swedish Avhandlingen handlar om hur radiovågor tar sig fram i miljöer där saker som hus, väggar och fönster är i vägen. Framför allt ligger fokus på hur signalen från en sändare placerad utomhus kan nå fram till en mobil terminal (t. ex. en mobiltelefon) som befinner sig inomhus. Hur mycket signalen dämpas när den passerar väggen är av stor betydelse när man ska avgöra hur långThis thesis deals with radio wave propagation in environments where the propagation is severely influenced by surrounding objects, mainly walls and other building structures. As an introduction, a brief description is given on propagation terms like loss, delay and dispersion along with system functions relevant for the topic. The focus is then placed on propagation from an outdoor transmitter to
We present post-compression of a TW class laser in a planar hollow waveguide. The viability of the compressed pulses for applications in strong-field physics is demonstrated by generating high-order harmonics in a gas jet.
The increasing size of the population results in that unbuilt spaces needing to be used for the construction of new facilities. Large construction sites can generate disturbing vibrations to nearby buildings, both while construction is underway and afterwards through the operation of subways, for example. The establishment of new areas close to, for example, motorways and railways increases the ri
The main goal of my studies was obtaining bulk acoustofluidic devices able to achieve high energy density inside a water-filled cavity. This led us to explore the interplay of sound and thermal effects more in details. Hence, this thesis covers both thermoacoustic effects in Bulk Acoustic Wave devices and a revisited approach for designing them, focusing on achieving good performance. Thermoacoust
This thesis treats the problem of transient electromagnetic pulse propagation in temporally dispersive media. The analysis is performed using time-domain techniques. In particular, the dispersive wave splitting which decouples the Maxwell equations both in vacuum and inside the medium is utilized. Complex time-dependent electromagnetic fields are introduced. These fields simplify the Maxwell equat
We use a train of sub-200 attosecond extreme ultraviolet (XUV) pulses with energies just above the ionization threshold in argon to create a train of temporally localized electron wave packets. We study the energy transfer from a strong infrared (IR) laser field to the ionized electrons as a function of the delay between the XUV and IR fields. When the wave packets are born at the zero crossings o
Movement of snowmelt water through a thin saturated layer at the infiltrating base of a snowpack is modelled by applying the kinematic wave theory. Analytical solutions are obtained for flow depth, velocity and discharge assuming that the rate of input to the saturated layer due to vertical percolation is constant. This assumption results in a linear rise and recession of the snowmelt hydrograph.
