description: A 2016-os évben jelentős változások következtek be Magyarországon a számviteli beszámolás területén. Ezek a változások minden aktív számviteli szakember munkájára hatással vannak. Egyrészt a biztosítók és egyéb pénzügyi vállalkozások, tőzsdén jegyzett társaságok és az anyavállalatuk felé a konszolidációhoz IFRS-adatcsomagot készítők a 2016-os idei üzleti évtől kezdődően választhatják, hogy az egyedi beszámolójukat a magyar számviteli törvény helyett a Nemzetközi Pénzügyi Beszámolási Standardok alapján készítik el. Másrészt azon vállalkozások, akik nem tartoznak az előbbi vállalkozások közé, ugyancsak hatalmas változásokkal kell, hogy szembenézzenek. A 2015-ben elfogadott számviteli törvényt érintő módosítások minden eddiginél nagyobb változást jelentenek a 2016-os évről készítendő beszámolókban. Ezek a változások, mint például a rendkívüli eredménykategória eltörlése és a mérleg szerinti eredmény megszüntetése tagadhatatlanul az IFRS-ekhez való konvergenciát testesítik meg. A kutatás célja bemutatni, hogy IFRS-ek bevezetése során milyen kihívásokat kell leküzdeni. Mindezt olyan kutatások eredményeinek bemutatása révén, melyek korábbi, külföldön megvalósított IFRS-bevezetésekről készültek. --------- In 2016 significant changes have occurred in Hungary in the field of financial reporting. These changes impact on all active accounting professional’s daily lives. This is the first business year, when the insurance companies and other financial firms, the listed companies and the companies who reported according to the IFRS to their parent company because of the consolidation can prepare their separate financial reports in accordance with International Financial Reporting Standards (IFRS) instead of the Hungarian law of accountancy. The rest of the companies should also be tremendous changes to face. The amendments to the Hungarian law of accountancy adopted in 2015 are very significant and impact almost everyone in this area. These changes such as the abolition of the balance sheet profit and the extraordinary profit category are undeniable convergence to the IFRS. The aim of this paper is to show the challenges of the IFRS adoption through the presentation of recent foreign research results.

description: The spin dynamics of GdI_2 have been investigated by ESR spectroscopy. The temperature dependences of the resonance field and ESR intensity are well described by the model for the spin susceptibility proposed by Eremin et al. [Phys. Rev. B 64, 064425 (2001)]. The temperature dependence of the resonance linewidth shows a maximum similar to the electrical resistance and is discussed in terms of scattering processes between conduction electrons and localized spins.

description: A turizmus sajátossága a terek speciális használata. A turizmus térhasználata során rendelkezésre álló terek mind az urbánus, mind a vidéki területeken egyformán használhatók, viszont egymástól eltérő tulajdonságokkal rendelkeznek. Az egészségturizmus egyik jellemzője, hogy valamilyen természeti tényező igénybevételével, annak lehetőségével vagy orvosi felügyelettel történik meg a szolgáltatások használata. Az egészségturisztikai célhelyek és desztinációk zömében a vidéki környezetben találhatóak, amelynek kialakulásában nagy szerepet játszott a történeti fejlődés. Az egészségturisztikai szolgáltatók számára az urbánus környezet nem kizáró ok, de ez esetben nem egy turisztikai desztináció helyét, hanem a saját vállalkozásnak vagy speciális gyógymódjának használati helyét jelöli meg egyfajta saját márkás desztinációként. A turizmus tervezése, térbeli elhelyezése kiemelten foglalkoztatja a tervező mérnököket és a beruházók fantáziáját. A verseny óriási, és világszintű újdonsággal csak azok a projektek tudnak kitűnni, amelyek megfelelően magas színvonalú tudással rendelkeznek a turizmus komplex folyamatáról. Jelen munkámban egy ilyen magas színvonalú és komplex tértervezéssel párosuló új egészségturisztikai desztináció esettanulmányán keresztül kívánom bemutatni a professzionális turisztikai tervezés lehetőségeit. ---------- The special use of space is among the distinctive features of tourism. The spaces available for tourism can be utilised both in urban and rural areas; however, they usually have different characteristics. One of the special characteristics of health tourism is that the services – that often rely on the use of natural assets - are offered under medical supervision. Health tourism destinations are mostly located in rural areas, with a long historical development background. Of course, urban regions can also offer health tourism services, but in these cases they are more often referred to by the name of the service provider or the service itself (as a brand), and not by the name of their location. Tourism space planning is an important issue for spatial designers and tourism investors. Because of the fierce competition within the field, state-of-the-art projects must have an excellent knowledge of the complex processes of tourism. My study aims to explore the opportunities in professional tourism planning by introducing a case study of a new health tourism destination which was implemented with the use of world class complex spatial design.

description: The Kuramoto model is a paradigm for studying oscillator networks with interplay between coupling tending towards synchronization, and heterogeneity in the oscillator population driving away from synchrony. In continuum versions of this model an oscillator population is represented by a probability density on the circle. Ott and Antonsen identified a special class of densities which is invariant under the dynamics and on which the dynamics are low-dimensional and analytically tractable. The reduction to the OA manifold has been used to analyze the dynamics of many variants of the Kuramoto model. To address the fundamental question of whether the OA manifold is attracting, we develop a systematic technique using weighted averages of Poisson measures for analyzing dynamics off the OA manifold. We show that for models with a finite number of populations, the OA manifold is {\it not} attracting in any sense; moreover, the dynamics off the OA manifold is often more complex than on the OA manifold, even at the level of macroscopic order parameters. The OA manifold consists of Poisson densities $ρ_ω$. A simple extension of the OA manifold consists of averages of pairs of Poisson densities; then the hyperbolic distance between the centroids of each Poisson pair is a dynamical invariant (for each $ω$). These conserved quantities, defined on the double Poisson manifold, are a measure of the distance to the OA manifold. This invariance implies that chimera states, which have some but not all populations in sync, can never be stable in the full state space, even if stable in the OA manifold. More broadly, our framework facilitates the analysis of multi-population continuum Kuramoto networks beyond the restrictions of the OA manifold, and has the potential to reveal more intricate dynamical behavior than has previously been observed for these networks.

On the lattice we prove that solutions are polynomially bounded in time for any bounded data. In the continuum, local existence is proved for real analytic data by a Newton iteration scheme. Global existence for NLS with a regularized nonlinearity follows by analyzing a local energy norm.

description: The Environment of Lyman Break Analogues (ELBA) survey is an imaging survey of 33 $deg^{2}$ of the southern sky. The survey was observed in {\it u}, {\it g}, {\it r}, and {\it i} bands with the Dark Energy Camera (DECam) on the Blanco telescope. The main goal of this project is to investigate the environment of Lyman break analogues (LBAs), low-redshift (z $\sim $0.2) galaxies that are remarkably similar to typical star-forming galaxies at z $\sim$ 3. We explore whether the environment has any influence on the observed properties of these galaxies, providing valuable insight on the formation and evolution of galaxies over cosmic time. Using the Nearest Neighbour method, we measure the local density of each object ranging from small to large scales (clusters of galaxies). Comparing the environment around LBAs with that of the general galaxy population in the field, we conclude that LBAs, on average, populate denser regions at small scales ($\sim$ $1.5Mpc$), but are located in similar environment to other star-forming galaxies at larger scales ($\sim$ $3.0 Mpc$). This offers evidence that nearby encounters such as mergers may influence the star formation activity in LBAs, before infall onto larger galaxy clusters. We interpret this an indication of galaxy preprocessing, in agreement with theoretical expectations for galaxies at z $\sim$ 2 -3 where the gravitational interactions are more intense in early formation processes of this objects

title: Regulation of RNA Polymerase II Transcription in Schizosaccharomyces pombe by SpELL and Associated Factor SpEAF
Creators: name: Banks, Charles Antony Scott
Publisher: name: The Open University
Year: 2010

description: RNA polymerase II (pol II) synthesised RNAs encode for proteins (mRNA), aid in splicing and telomere maintenance (snRNPs), and down-regulate gene expression (microRNAs). Therefore, pol II can be a critical target for modulating differential gene expression. Understanding mechanisms that underlie the various stages of transcription will elucidate origins of gene misexpression, which can give rise to a host of human diseases. Eleven-nineteen lysine-rich in leukaemia, (ELL), affects pol II transcription. The ELL gene was initially identified as a gene translocation fusion partner of the mixed lineage leukaemia (MLL) gene in patients with acute myeloid leukaemia (I). ELL interacts with pol II in vitro, increasing the rate at which it elongates nascent transcripts (2). Two ELL-associated factors, EAFI and EAF2, bind ELL family members and act as strong positive regulators of their transcription activities (3).

Although ELL and EAF orthologs have been identified in metazoan organisms, previous attempts to identify similar elongation factors in lower eukaryotes had been unsuccessful. This thesis describes the identification of two genes in the yeast Schizosaccharomyces pombe, ell I and eafl, that share some sequence similarity to highly conserved regions in ELL and EAEI/EAF2 (4). Biochemical characterisation of these gene products, SpELL and SpEAF, shows that they have similar activities to their metazoan counterparts in vitro. Using a whole genome approach, I identified genes that are likely direct targets for regulation by SpELL/SpEAF in cells. Notably, ELL and EAF functions have not been studied previously at a genomic level. One SpELL/SpEAF target, sme2, was used as a model gene to investigate how the SpELL/SpEAF complex is recruited to chromatin. Together with results of in vitro binding assays, these results suggest the SpELL/SpEAF complex is recruited to pol II via the SpELL subunit.

Automatic Classification (also called clustering) is an important and difficult problem in many Astrophysical experiments, for instance, Gamma Ray Burst classification, or gamma-hadron separation. After a brief introduction to classification problem, we discuss Self-Organising Maps in section 2. Section 3 discusses with various models of growing neural networks and finally in section 4 we discuss the research perspectives in growing neural networks for efficient classification in astrophysical problems.

description: Ego networks have proved to be a valuable tool for understanding the relationships that individuals establish with their peers, both in offline and online social networks. Particularly interesting are the cognitive constraints associated with the interactions between the ego and the members of their ego network, whereby individuals cannot maintain meaningful interactions with more than 150 people, on average. In this work, we focus on the ego networks of journalists on Twitter, considering 17 different countries, and we investigate whether they feature the same characteristics observed for other relevant classes of Twitter users, like politicians and generic users. Our findings are that journalists are generally more active and interact with more people than generic users, regardless of their country. Their ego network structure is very aligned with reference models derived from the social brain hypothesis and observed in general human ego networks. Remarkably, the similarity is even higher than the one of politicians and generic users ego networks. This may imply a greater cognitive involvement with Twitter than with other social interaction means. From a dynamic perspective, journalists have stable short-term relationships that don’t change a lot over time. In the longer term, though, ego networks can be pretty dynamic, especially in the innermost circles. Moreover, the ego-alter ties of journalists are often information-driven, as they are mediated by hashtags. Finally, we observe that highly popular journalists tend to engage with other journalists of similar popularity, and vice versa. Instead, when interacting with generic users, their popularity doesn't seem to play a major role.

description: Was F.F. Bosworth’s first wife, Estelle, a victim of the Spanish Flu? After reading Daniel Isgrigg’s excellent article, “How Pentecostals Responded to the 1918 ‘Spanish Influenza,'” I decided to review again the life history of Bosworth. I remembered his first wife, Estelle, had died in November 1919 after contracting “influenza.” So I took a closer look at her death. While I can’t be certain at this point about the exact cause of her death, it seems highly probable that she was indeed a victim of the dreaded Spanish Flu. #FFBosworth #BosworthMatters
Non-equilibrium conductance of a three-terminal quantum dot in the Kondo regime: Perturbative Renormalization Group

description: Motivated by recent experiments, we consider a single-electron transistor in the Kondo regime which is coupled to three leads in the presence of large bias voltages. Such a steady-state non-equilibrium system is to a large extent governed by a decoherence rate induced by the current through the dot. As the two-terminal conductance turns out to be rather insensitive to the decoherence rate, we study the conductance in a three-terminal device using perturbative renormalization group and calculate the characteristic splitting of the Kondo resonance. The interplay between potential biases and anisotropy in coupling to the three leads determines the decoherence rate and the conditions for strong coupling.

description: We construct new entanglement distillation protocols by interpolating between the recurrence and hashing protocols. This leads to asymptotic two-way distillation protocols, resulting in an improvement of the distillation rate for all mixed Bell diagonal entangled states, even for the ones with very high fidelity. We also present a method how entanglement-assisted distillation protocols can be converted into non-entanglement-assisted protocols with the same yield.

title: Biochemical and Functional Analysis of the PREP1 Interactor: p160 Myb Binding Protein 1
Creators: name: Mori, Silvia
Publisher: name: The Open University
Year: 2010

description: p160 myb binding protein 1a (p160) is a nucleolar protein the function of which is poorly understood. To date, only a few interactors, mainly transcription factors (e.g. Myb, Jun), have been characterized. One of these is Prep1, an homeodomain transcription factor essential for embryonic development, involved, in particular, in haemopoiesis, angiogenesis, and oculogenesis, as well as in apoptosis and tumorigenesis. In this thesis work I show that p160 is capable of binding Prep1 through the same region as another Prep1 interactor, Pbx, and that such binding inhibits Prepl action on the HoxB enhancer. I demonstrate that the two proteins, Prep1 and p160, interact mainly in the nucleoplasm and hence only under conditions that favor p160 translocation from the nucleolus to the nucleoplasm (e.g. after treatment with Actinomycin D). Moreover I studied p160 during cell-cycle, since during mitosis p160 assumes a para-chromosomal localization. In HeLa cells, depletion of p160 by siRNA transfection decreases the proliferation rate and increases cell-death, mostly via apoptosis. p160-depleted HeLa cells accumulate in the G2/M phases of the cell-cycle and show a variety of mitotic defects: extended division time and structural alterations of the metaphasic plate. All these data suggest that p160 is essential for proper cell division. This phenotype is also in agreement with my observations that p160 down-regulated NIH 3T3 cells are more sensitive to transformation by Ras and Myc and undergo spontaneous neoplastic transformation even in the absence of oncogenes.

description: Motivated by the recent scanning tunneling microscopy (STM) experiments [J. E. Hoffman {\it et al.}, Science {\bf 297}, 1148 (2002); K. McElroy {\it et al.}, Nature (to be published)], we investigate the real space local density of states (LDOS) induced by weak disorder in a d-wave superconductor. We first present the energy dependent LDOS images around a single weak defect at several energies, and then point out that the experimentally observed checkerboard pattern in the LDOS could be understood as a result of quasiparticle interferences by randomly distributed defects. It is also shown that the checkerboard pattern oriented along $45^0$ to the Cu-O bonds at low energies would transform to that oriented parallel to the Cu-O bonds at higher energies. This result is consistent with the experiments.

description: The present study is the first assessment of oxidative stress (OS) in fish species inhabiting the Bulgarian Black Sea coastal zone. The fish were caught during trawl selectivity experiments from different localities of the northern and southern coastal regions. The pro/antioxidant status of fish individuals was assessed by measuring standard OS biomarkers (lipid peroxidation, glutathione concentration, activities of superoxide dismutase and catalase) in gills and liver. Differences in the concentration and activity of OS biomarkers in the studied organs were clearly demonstrated. It was found that the level of OS in the studied fish species differed depending both on the species and on the coastal region they inhabit. Our results demonstrated for the first time the presence of OS in fish inhabiting coastal ecosystems of the Bulgarian Black sea sector with different quality of the marine environment. Obviously, further studies are needed for the assessment of multiple stressor effects on the ecology of Bulgarian Black Sea fish populations.

title: The role of the neuregulins in the nucleus
Creators: name: Wang, Ming
Publisher: name: University of Kent
Year: 2022

description: The neuregulins (NRGs) are ligands for receptor tyrosine kinases of the ErbB family. The NRG gene family consists of four members, NRG 1- 4 encoding different isoforms due to alternative splicing. NRG signalling has been implicated in normal development and in the pathology of many diseases. Using immunohistochemical staining of tissue arrays, we detected that NRG 1 a and 1 ~ localised to the cell nuclei of a range of normal and human cancer tissues. The ~3 isoform of NRG 1 localised to two subnuclear compartments: nucleoli and spliceosomes. We tagged NRG 1 ~3 with photoactivateable GFP and demonstrated that the fusion protein re-Iocalised from nucleoli to spliceosomes over a ninety minute period. Using wild type NRG 1 ~3 and its two mutants which localised exclusively to spliceosomes or to nuc1eoH, we explored the possible functions of intranuclear NRG 1 ~3 in each of these compartments separately. We showed using an array capable of detecting 42 receptor tyrosine kinases that wild type NRG 1 and a mutant exclusively local ising to spliceosomes increased phosphorylation and/or expression of the ErbB4 and ErbB2 receptors. Using a transcriptomic analysis the same two constructs induced expression of messenger RNA of Heat Shock Protein 70B' and we confirmed its increased expression at the protein level using western blot analysis. This data supports the hypothesis that intranuclear NRGs could activate receptor signalling and alter gene expression when localised in spliceosomes.

description: We report a coexistence of superconductivity and antiferromagnetism in five-layered compound HgBa$_2$Ca$_4$Cu$_5$O$_y$ (Hg-1245) with $T_c=108$ K, which is composed of two types of CuO$_2$ planes in a unit cell; three inner planes (IP's) and two outer planes (OP's). The Cu-NMR study has revealed that the optimallydoped OP undergoes a superconducting (SC) transition at $T_c=108$ K, whereas the three underdoped IP's do an antiferromagnetic (AF) transition below $T_N\sim$ 60 K with the Cu moments of $\sim (0.3-0.4)μ_B$. Thus bulk superconductivity with a high value of $T_c=108$ K and a static AF ordering at $T_N=60$ K are realized in the alternating AF and SC layers. The AF-spin polarization at the IP is found to induce the Cu moments of $\sim0.02μ_B$ at the SC OP, which is the AF proximity effect into the SC OP.

The theory covers both the linear and nonlinear transport regime, takes non-collinear magnetization of the leads into account, and allows for an externally-applied magnetic field. We derive generalized rate equations for the dot's occupation and accumulated spin and discuss the influence of the dot's spin on the transmission. A negative differential conductance and a nontrivial dependence of the conductance on the angle between the lead magnetizations is predicted.

description: This study sought to gauge Florida’s consumers’ willingness to pay for protecting the future of Florida’s water supply from 2013 to 2016. This study used a value approach for estimating consumer’s willingness to pay for a 10 percent and a 50 percent increase in their water bill. The study also sought to identify dissonance between Florida’s consumers to determine influencers of their willingness to pay. The study found an increasing percentage of consumers willing to support the protection of Florida’s water supply since 2013. As well, income was a common factor influencing respondent’s willingness to pay. Knowing this dissonance can help decision makers make informed polices and regulations about future water conservation strategies for the future.

description: High orders in perturbation theory can be calculated by the Lipatov method. For most field theories, the Lipatov asymptotics has the functional form c a^N Γ(N+b) (N is the order of perturbation theory); relative corrections to this asymptotics have the form of a power series in 1/N. The coefficients of high order terms of this series can be calculated using a procedure analogous to the Lipatov approach and are determined by the second instanton in the considered field theory. These coefficients are calculated quantitatively for the n-component ϕ^4 theory under the assumption that the second instanton is (i) a combination of two elementary instantons and (ii) a spherically asymmetric localized function. The technique of two-instanton calculations is developed, as well as the method for integrating over rotations of an asymmetric instanton in the coordinate state.

description: In strongly correlated electron materials, charge, spin and orbital degrees of freedom exhibit an intimate relationship, leading to new emergent phases that seemingly break the symmetries of the underlying crystal and are highly sensitive to external stimuli. This is well illustrated in the Ruddlesden-Popper series of the strontium ruthenates, Sr_{n+₁}Ru_nO_{₃n+₁}, where a wide range of properties attributed to such physics can be found, including unconventional superconductivity, quantum criticality, metamagnetic transitions and ferromagnetism. In this thesis, using ultra-low temperature scanning tunneling microscopy, I show a detailed study of the low-energy electronic states at the surface of Sr₂RuO₄, an unconventional superconductor, and Sr₃Ru₂O₇, an itinerant metamagnet associated with quantum criticality. I demonstrate that the increased structural distortions in the surface layer lead to considerable changes in the Fermi surface, allowing the stabilization of new emergent phases beyond those accessible in the bulk. At the surface of Sr₂RuO₄, we find that the surface reconstruction leads to checkerboard charge order intertwined with nematicity, intimately linked with four van Hove singularities within 5 meV of the Fermi level. Including these orders in a tight-binding model gives excellent agreement with the experiment. By applying a magnetic field, one of the van Hove singularities splits, with one branch extrapolated to reach the Fermi energy at ~32 T, providing a textbook example of tuning towards a Zeeman-driven Lifshitz transition. Measurements at the surface of Sr₃Ru₂O₇ reveal a magnetic ground state, with substantial anisotropy of the electronic states. With increasing magnetic field, we observe the formation of a stripe order and were able to track a van Hove singularity shift across the Fermi energy. Our measurements establish the surface layer as having a distinct ground state from the bulk, undergoing a magnetic field induced Lifshitz transition at a magnetic field of ~11 T.
Newly Improved Ionization Corrections for the Neutral Interstellar Medium: Enabling Accurate Abundance Determinations in Star-forming Galaxies throughout the Universe

description: Studies measuring the chemical abundances of the neutral gas in star-forming galaxies (SFGs) require ionization correction factors (ICFs) to accurately measure their metal contents. In the work presented here we calculate newly improved ICFs for a sample of SFGs. These new corrections include both the contaminating ionized gas along the line of sight (ICF$_{\rm ionized}$) and unaccounted higher ionization stages in the neutral gas (ICF$_{\rm neutral}$). We make use of recently acquired spectroscopic observations taken with the Cosmic Origins Spectrograph (COS) on board Hubble to measure column densities for Fe II and Fe III. Using the Fe III/Fe II ratios as well as other physical properties (i.e. $\log$[L$_{\rm UV}$], $N$(H I), T, and $Z$) we generate ad-hoc photoionization models with CLOUDY to quantify the corrections required for each of the targets. We identify a luminosity threshold of $\log$[L$_{\rm UV}$]$\sim$ 40.75 erg s$^{-1}$ above which the ICF$_{\rm neutral}$ values for nitrogen are relatively higher (ICF$_{\rm neutral}=0.05$-0.7) than those for the rest of the elements (ICF$_{\rm neutral}\sim 0.01$). This behavior indicates that for the high UV luminosity objects, N II is found in non-negligible quantities in the neutral gas, making these ICF$_{\rm neutral}$ corrections critical for determining the true abundances in the interstellar medium. In addition, we calculate ICFs from a uniform grid of models covering a wide range of physical properties typically observed in studies of SFGs and extragalactic H II regions. We provide the community with tabulated ICF values for the neutral gas abundances measured from a variety of environments and applicable to chemical studies of the high redshift universe.

description: Two longstanding unemployment patterns were reversed in the 1980-82 recession. The nonmetro unemployment rate exceeded the metro rate and men's unemployment rate exceeded women's. The two reversals resulted primarily from changes in the labor force in recent years: the shift to a service economy, the expansion of women's role in the work place, and changes in women's working patterns.
Exploiting environmental resonances to enhance qubit quality factors

description: We discuss dephasing times for a two-level system (including bias) coupled to a damped harmonic oscillator. This system is realized in measurements on solid-state Josephson qubits. It can be mapped to a spin-boson model with a spectral function with an approximately Lorentzian resonance. We diagonalize the model by means of infinitesimal unitary transformations (flow equations), and calculate correlation functions, dephasing rates, and qubit quality factors. We find that these depend strongly on the environmental resonance frequency $Ω$; in particular, quality factors can be enhanced significantly by tuning $Ω$ to lie below the qubit frequency $Δ$.

description: Hay is an important field crop in the U.S., with over 54 million harvested acres in 2015. In many southern states, hay is an important input for cattle production, and reducing forage costs is crucial for improving the profitability of livestock operations. It is well known that crop yields and quality are significantly influenced by weather variations, which can have different impacts across geographical regions and over years. This study quantifies possible heterogeneous impacts in hay yield responses to weather variations in Oklahoma hay yields. The paper uses panel data on hay yields for Oklahoma’s 77 counties from 1977 to 2007. The weather variables include temperature and precipitation. A geographically weighted regression (GWR) approach is used to estimate the local effects of weather variations on hay yields in geographic regions. The GWR allows the relationships between hay yields and weather variations to vary across geographic regions. Results suggest that geographic variation does exist in hay’s response to weather. Accordingly, it is important to model hay production within a framework that allows weather response parameters to vary. Hay producers can reduce their production risk by incorporating models that permit geographical variation in how the local climate impacts yields.

title: The Dynamics of an Excited Hydrogen Atom in a Parallel Low Frequency Microwave and Static Field
Creators: name: Kelly, Nicholas Christopher
Publisher: name: The Open University
Year: 2011

description: This thesis examines the effect of parallel static and low frequency microwave fields on excited hydrogen atoms. By low frequency we mean, Ω0 = Ω/ωκ << 1, where Ω is the field frequency and ωκ is the Kepler frequency of the unperturbed excited electron. Experiments and calculations have shown that for certain field strengths, resonances arise, sometimes leading to enhanced ionisation. Approximate time-dependent one-dimensional Hamiltonians describing the classical dynamics were derived previously by Richards [51]. Here we derive a number of properties from these Hamiltonians and use these to predict and explain ionisation behaviour. Because the separatrix is a construct of classical dynamics affecting a relatively small area of phase space, it is unclear how it will affect the quantum mechanics of the system or how large the quantum numbers must be for measurable effects. For this reason, we derive a new quantal method to compute the ionisation probability for the system. The method is tested where possible and shown to accurately describe the general behaviour of the system. The method is applied to slowly switched fields and is computationally efficient, allowing calculations for high principal quantum numbers, n ≥ 800. We compare classical and quantum ionisation behaviour. Significant qualitative differences exist for low quantum numbers, n ~ 10, but quantitative differences exist, for higher quantum numbers, even for n ≥ 100. For slowly switched fields, the separatrix can considerably affect the ionisation structure. These effects are also manifest in the quantum mechanics for sufficiently high n, but even for n = 39, the influence of the separatrix is seen. Ionisation times are calculated for systems prepared in a single initial state and for mi- crocanonical distributions of initial states. Classically, motion near the separatrix is shown to lead to longer ionisation times at resonance. This is also seen in quantal calculations, even for quantum numbers as low as n =39, that is, those accessible by experiment.
