description: Here is discussed application of the Weyl pair to construction of universal set of quantum gates for high-dimensional quantum system. An application of Lie algebras (Hamiltonians) for construction of universal gates is revisited first. It is shown next, how for quantum computation with qubits can be used two-dimensional analog of this Cayley-Weyl matrix algebras, i.e. Clifford algebras, and discussed well known applications to product operator formalism in NMR, Jordan-Wigner construction in fermionic quantum computations. It is introduced universal set of quantum gates for higher dimensional system (``qudit''), as some generalization of these models. Finally it is briefly mentioned possible application of such algebraic methods to design of quantum processors (programmable gates arrays) and discussed generalization to quantum computation with continuous variables.

description: Relying only on the standard model of elementary particles and gravity, we study the details of a new source of gravitational waves whose origin is in quantum physics. Namely, it is well known that massless fields in curved backgrounds suffer from the so-called "trace anomaly". This anomaly can be cast in terms of new scalar degrees of freedom which take account of macroscopic effects of quantum matter in gravitational fields. The linearized effective action for these fields describes scalar (as opposed to transverse) gravitational waves, which are absent in Einstein's theory. Since these new degrees of freedom couple directly to the gauge field scalars in QCD, the epoch of the QCD phase transition in early universe is a possible source of primordial cosmological gravitational radiation. While the anomaly is most likely fully unsuppressed at the QCD densities (temperature is much higher than the u and d quark masses), just to be careful we introduced the window function which cuts-off very low frequencies where the anomaly effect might be suppressed. We then calculated the characteristic strain of the properly adjusted gravitational waves signal today. The region of the parameter space with no window function gives a stronger signal, and both the strain and the frequencies fall within the sensitivity of the near future gravitational wave experiments (e.g. LISA and The Big Bang Observer). The possibility that one can study quantum physics with gravitational wave astronomy even in principle is exciting, and will be of value for future endeavors in this field.

description: Thickenings of a metric space capture local geometric properties of the space. Here we exhibit applications of lower bounding the topology of thickenings of the circle and more generally the sphere. We explain interconnections with the geometry of circle actions on Euclidean space, the structure of zeros of trigonometric polynomials, and theorems of Borsuk-Ulam type. We use the combinatorial and geometric structure of the convex hull of orbits of circle actions on Euclidean space to give geometric proofs of the homotopy type of metric thickenings of the circle. Homotopical connectivity bounds of thickenings of the sphere allow us to prove that a weighted average of function values of odd maps $S^n \to \mathbb{R}^{n+2}$ on a small diameter set is zero. We prove an additional generalization of the Borsuk-Ulam theorem for odd maps $S^{2n-1} \to \mathbb{R}^{2kn+2n-1}$. We prove such results for odd maps from the circle to any Euclidean space with optimal quantitative bounds. This in turn implies that any raked homogeneous trigonometric polynomial has a zero on a subset of the circle of a specific diameter; these results are optimal.

We show that the dynamics of a single soliton coincides with that in the commutative model. We find that the singularity in the two-soliton moduli space, which exists in the commutative CP^1 model, disappears in the noncommutative model.We also show that the two-soliton metric has the smooth commutative limit.

description: We compute the evolution of interstellar dust in a hydrodynamic simulation of an isolated disc galaxy. We newly implement the evolution of full grain size distribution by sampling 32 grid points on the axis of the grain radius. We solve it consistently with the chemical enrichment and hydrodynamic evolution of the galaxy. This enables us to theoretically investigate spatially resolved evolution of grain size distribution in a galaxy. The grain size distribution evolves from a large-grain-dominated ($\gtrsim 0.1~μ$m) phase to a small-grain production phase, eventually converging to a power-law-like grain size distribution similar to the so-called MRN distribution. We find that the small-grain abundance is higher in the dense ISM in the early epoch ($t\lesssim 1$ Gyr) because of efficient dust growth by accretion, while coagulation makes the small-grain abundance less enhanced in the dense ISM later. This leads to steeper extinction curves in the dense ISM than in the diffuse ISM in the early phase, while they show the opposite trend later. The radial trend is also described by faster evolution in the inner part. We also confirm that the simulation reproduces the observed trend in the relation between dust-to-gas ratio and metallicity, and in the radial gradients of dust-to-gas ratio and dust-to-metal ratio. Since the above change in the grain size distribution occurs at $t\sim 1$ Gyr, the age and density dependence of grain size distribution has a significant impact on the extinction curves even at high redshift.

description: We report the magnetic phase diagram of single-crystalline LiFePO$_4$ in magnetic fields up to 58~T and present a detailed study of magneto-elastic coupling by means of high-resolution capacitance dilatometry. Large anomalies at \tn\ in the thermal expansion coefficient $α$ imply pronounced magneto-elastic coupling. Quantitative analysis yields the magnetic Grüneisen parameter $γ_{\rm mag}=6.7(5)\cdot 10^{-7}$~mol/J. The positive hydrostatic pressure dependence $dT_{\rm N}/dp = 1.46(11)$~K/GPa is dominated by uniaxial effects along the $a$-axis. Failure of Grüneisen scaling below $\approx 40$~K, i.e., below the peak temperature in the magneto-electric coupling coefficient [\onlinecite{toft2015anomalous}], implies several competing degrees of freedom and indicates relevance of recently observed hybrid excitations~[\onlinecite{yiu2017hybrid}]. A broad and strongly magnetic-field-dependent anomaly in $α$ in this temperature regime highlight the relevance of structure changes. Upon application of magnetic fields $B||b$-axis, a pronounced jump in the magnetisation implies spin-reorientation at $B_{\rm SF} = 32$~T as well as a precursing phase at 29~T and $T=1.5$~K. In a two-sublattice mean-field model, the saturation field $B_{\rm sat,b} = 64(2)$~T enables the determination of the effective antiferromagnetic exchange interaction $J_{\rm af} = 2.68(5)$~meV as well as the anisotropies $D_{\rm b} = -0.53(4)$~meV and $D_{\rm c} = 0.44(8)$~meV.

description: One possible and natural derivation from the collisionless cold dark matter (CDM) standard cosmological framework is the assumption of the existence of interactions between dark matter (DM) and photons or neutrinos. Such possible interacting dark matter (IDM) model would imply a suppression of small-scale structures due to a large collisional damping effect, even though the weakly interacting massive particle (WIMP) can still be the DM candidate. Because of this, IDM models can help alleviate alleged tensions between standard CDM predictions and observations at small mass scales. In this work, we investigate the properties of DM halo substructure or subhalos formed in a high-resolution cosmological N-body simulation specifically run within these alternative models. We also run its CDM counterpart, which allowed us to compare subhalo properties in both cosmologies. We show that, in the lower mass range covered by our simulation runs, both subhalo concentrations and abundances are systematically lower in IDM compared to the CDM scenario. Yet, as in CDM, we find that median IDM subhalo concentration values increase towards the innermost regions of their hosts for same mass subhalos. Also similarly to CDM, we find IDM subhalos to be more concentrated than field halos of the same mass. Our work has a direct application on studies aimed at the indirect detection of DM where subhalos are expected to boost the DM signal of their host halos significantly. From our results, we conclude that the role of halo substructure in DM searches will be less important in interacting scenarios than in CDM, but is nevertheless far from being negligible.

title: implications for conservation and future reintroduction

description: Along with many other species, the Scotch argus (Erebia aethiops) has suffered a decline in range, particularly in England, with some populations experiencing long-term isolation. This thesis studied the genetic structure of the species in Britain on a national scale and at the metapopulation level with the aim of advising future management of the species and potential reintroductions across its former range in England. AFLP analysis carried out on populations from England, Scotland and the western Scottish islands found that there was no significant difference in genetic diversity between the regions. None of the study populations showed clear signs of inbreeding, suggesting inbreeding depression (a reduction in fitness due to inbreeding) is not a concern. Even those populations in England which were probably isolated for a long time (e.g. Arnside Knott) showed genetic diversity levels that were relatively high. However, populations were genetically differentiated with significant differences observed among both regions and populations. Genetic differences among populations were significantly related to geographic distance. On a local scale, the Smardale Gill metapopulation was found to be genetically robust with gene flow occurring between all patches. This was confirmed with a mark-release-recapture study which show that males are able to move long distances and the total population estimate for the whole area was high (over 7000 individuals). However, females moved only small distances, and none were reported to move between patches, suggesting that gene flow between patches is only maintained by males and colonisation of empty patches is limited. The results of this study provide support for several management recommendations for the conservation of the species. The struggling Arnside Knott population at the most southern range margin was found not to be suffering from inbreeding, so it is recommended that no supplementary translocations be made until the cause of the decline is determined. As populations were genetically differentiated, a geographically close population is recommended as a source to increase the chance of success of any future reintroduction. In this respect the Smardale Gill metapopulation appears the most suitable source for future reintroduction attempts across the species’ former range in England.

description: In this thesis, efficient isomorph-free generation of graph classes with the method of generation by canonical construction path(GCCP) is discussed. The method GCCP has been invented by McKay in the 1980s. It is a general method to recursively generate combinatorial objects avoiding isomorphic copies. In the introduction chapter, the method of GCCP is discussed and is compared to other well-known methods of generation. The generation of the class of quartic graphs is used as an example to explain this method. Quartic graphs are simple regular graphs of degree four. The programs, we developed based on GCCP, generate quartic graphs with 18 vertices more than two times as efficiently as the well-known software GENREG does. This thesis also demonstrates how the class of principal graph pairs can be generated exhaustively in an efficient way using the method of GCCP. The definition and importance of principal graph pairs come from the theory of subfactors where each subfactor can be modelled as a principal graph pair. The theory of subfactors has applications in the theory of von Neumann algebras, operator algebras, quantum algebras and Knot theory as well as in design of quantum computers. While it was initially expected that the classification at index 3 + √5 would be very complicated, using GCCP to exhaustively generate principal graph pairs was critical in completing the classification of small index subfactors to index 5¼. The other set of classes of graphs considered in this thesis contains graphs without a given set of cycles. For a given set of graphs, H, the Turán Number of H, ex(n,H), is defined to be the maximum number of edges in a graph on n vertices without a subgraph isomorphic to any graph in H. Denote by EX(n,H), the set of all extremal graphs with respect to n and H, i.e., graphs with n vertices, ex(n,H) edges and no subgraph isomorphic to any graph in H. We consider this problem when H is a set of cycles. New results for ex(n, C) and EX(n, C) are introduced using a set of algorithms based on the method of GCCP. Let K be an arbitrary subset of {C3, C4, C5, . . . , C32}. For given n and a set of cycles, C, these algorithms can be used to calculate ex(n, C) and extremal graphs in Ex(n, C) by recursively extending smaller graphs without any cycle in C where C = K or C = {C3, C5, C7, . . .} ᴜ K and n≤64. These results are considerably in excess of the previous results of the many researchers who worked on similar problems. In the last chapter, a new class of canonical relabellings for graphs, hierarchical canonical labelling, is introduced in which if the vertices of a graph, G, is canonically labelled by {1, . . . , n}, then G\{n} is also canonically labelled. An efficient hierarchical canonical labelling is presented and the application of this labelling in generation of combinatorial objects is discussed.

description: A suite of real-time instruments was used to sample vehicle emissions at the California Air Resources Board Haagen-Smit facility. Eight on-road, spark-ignition gasoline and three alternative vehicles were tested on a chassis dynamometer and the emissions were diluted to atmospherically relevant concentrations (0.5–30 μg/m3). An Aerodyne high resolution time-of-flight aerosol mass spectrometer (HR-ToF-MS) characterized the real-time behavior of the nonrefractory organic and inorganic particulate matter (PM) in vehicle emissions. It was found that the emission of particulate organic matter (POM) was strongly affected by engine temperature and engine load and that the emission concentrations could vary significantly by vehicle. Despite the small sample size, consistent trends in chemical characteristics were observed. The composition of vehicle POM was found to be related to overall PM mass concentration where the oxygen-to-carbon (O/C) ratio tended to increase at lower concentration and had an average value of 0.057 ± 0.047, with a range from 0.022 to 0.15. The corresponding fraction of particle-phase CO2+, or f44, ranged from 1.1% to 8.6% (average = 2.1%) and exhibited a linear variation with O/C. The average mass spectrum from all vehicles tested was also compared to those of hydrocarbon-like organic aerosol (HOA) observed in ambient air and the agreement is very high. The results of these tests offer the vehicle emissions community a first glimpse at the real-time chemical composition and variation of vehicle PM emissions for a variety of conditions and vehicle types at atmospherically relevant conditions and without chemical interferences from other primary or secondary aerosol sources.

description: In this paper we have considered the particle creation in the spatially closed Robertson-Walker space-time. We considered a real massive scalar field which conformally coupled to the Robertson-Walker background. With the dependence of the scale factor on time, the case under consideration is a dynamical Casimir effect with moving boundaries.

title: Isovector One-Quadrupole-Phonon Excitations of Heavy Vibrational Nuclei
Creators: name: Kern, Ralph
Publisher: name: UNSPECIFIED

description: The investigation and identification of mixed-symmetry states stand in the focus of this work. They are formed from collective vibrations and rotations of valence neutrons and protons, where the two nucleon groups oscillate partly out-of-phase with respect to each other. In vibrational nuclei, the $2^+_\mathrm{1,ms}$ state is the lowest-lying mixed-symmetry level. For the $N=80$ isotones, the sub-shell closure at $Z=58$ highly effects the structure of the $2^+_\mathrm{1,ms}$ state. Up to $Z=56$, the isotones have isolated $2^+_\mathrm{1,ms}$ states, but for $^{138}$Ce ($Z=58$), it is strongly fragmented. This behaviour is explained by the valence-shell stabilization, which is lacking at the proton sub-shell closure $Z=58$. For addressing the question how the $2^+_\mathrm{1,ms}$ state behaves while going beyond the proton sub-shell closure, projectile Coulomb-excitation experiments were performed. They took place at HIE-ISOLDE at CERN using the $\gamma$-ray spectrometer Miniball with the radioactive ion beams of the $N=80$ isotones $^{140}$Nd and $^{142}$Sm. The enhanced $B(M1;2^+_3\to2^+_1)=0.26^{+0.11}_{-0.10}\,\mu_\mathrm{N}^2$ strength and the low upper limit $B(M1;2^+_4\to2^+_1)<0.04\,\mu_\mathrm{N}^2$ of $^{140}$Nd showed the restoration of the valence-shell stabilization at $Z=60$. From the $M1$ strength distribution, the quality of the $F$ spin of $^{140}$Nd was determined by the $F$-spin mixing matrix element $V_\mathrm{F-mix}<7^{+13}_{-7}\,\mathrm{keV}$. The reduced mixing matrix element supports the proposed restoration of the valence-shell stabilization. For $^{142}$Sm, the Coulomb-excitation analysis delivered an upper limit $B(M1;2^+_3\to2^+_1)<0.14^{+0.37}_{-0.01}\,\mu_\mathrm{N}^2$, which is not in conflict with the conclusions from the $^{140}$Nd experiment. A complementary $\gamma$-$\gamma$ correlation measurement after $\beta^+$/$\epsilon$ decay to determine the indispensable $E2$/$M1$ multipole-mixing ratio $\delta$ of the $2^+_3\to2^+_1$ transition of $^{142}$Sm was designed for the Heavy Ion Laboratory in Warsaw and accepted. For the stable $^{202}$Hg, a projectile Coulomb-excitation experiment was conducted at the ATLAS facility at the ANL using the $\gamma$-ray spectrometer Gammasphere. Simultaneously, angular particle-$\gamma$ correlations were measured with the aim of deducing $\delta$. In $^{202}$Hg a pronounced $B(M1;2^+_7\to2^+_1)=0.18(8) \,\mu_\mathrm{N}^2$ with $\delta=0.06(4)$ was found, while an upper limit for the neighboring transition was obtained, $B(M1;2^+_8\to2^+_1)<0.027 \,\mu_\mathrm{N}^2$. For the first time in the mass region $A\approx200$, the $F$-spin mixing quality was determined, for $^{202}$Hg and $^{204}$Hg, $V_\mathrm{F-mix}=9(2)^{+3}_{-3}\,\mathrm{keV}$ and $11(1)^{+4}_{-5}\,\mathrm{keV}$, respectively. Consequently, $F$ spin can be considered a sufficiently good approximate quantum number in the investigated nuclei of $N,Z=80$ near doubly-magic isotopes.

Heteroepitaxial Thin-Film Growth of a Ternary Nitride Semiconductor CaZn2N2

description: Zinc-based nitride CaZn2N2 films grown by molecular beam epitaxy (MBE) with a plasma-assisted active nitrogen-radical source are promising candidates of next-generation semiconductors for light-emitting diodes and solar cells. This nitride compound has previously only been synthesized in a bulk form by ultrahigh-pressure synthesis at 5 GPa. Three key factors have been found to enable heteroepitaxial film growth: (i) precise tuning of the individual flux rates of Ca and Zn, (ii) the use of GaN template layers on sapphire c-plane as substrates, and (iii) the application of MBE with an active N-radical source. Because other attempts at physical vapor deposition and thermal annealing processes have not produced CaZn2N2 films of any phase, this rf-plasma-assisted MBE technique represents a promising way to stabilize CaZn2N2 epitaxial films. The estimated optical band gap is ~1.9 eV, which is consistent with the value obtained from bulk samples. By unintentional carrier doping, n- and p-type electronic conductions are attained with low carrier densities of the order of 1013 /cm3. These features represent clear advantages when compared with Zn-based oxide semiconductors, which usually have much higher carrier densities irrespective of their intentionally undoped state. The carrier mobilities at room temperature are 4.3 cm2/(Vs) for electrons and 0.3 cm2/(Vs) for hole carriers, which indicates that transport properties are limited by grain boundary scattering, mainly because of the low-temperature growth at 250 °C, which realizes a high nitrogen chemical potential.

description: We consider the change of entanglement of formation $ΔE$ produced by the Hadamard-CNOT circuit on a general (pure or mixed) state $ρ$ describing a system of two qubits. We study numerically the probabilities of obtaining different values of $ΔE$, assuming that the initial state is randomly distributed in the space of all states according to the product measure recently introduced by Zyczkowski {\it et al.} [Phys. Rev. A {\bf 58} (1998) 883].

The nonmodal kinetic theory for the electrostatic instabilities of a plasma with a sheared Hall current

description: The kinetic theory for the instabilities driven by the Hall current with a sheared current velocity, which has the method of the shearing modes or the so-called non-modal approach as its foundation, is developed. The developed theory predicts that in the Hall plasma with the inhomogeneous electric field, the separate spatial Fourier mode of the perturbations is determined in the frame convected with one of the plasma components. Because of the different shearing of the ion and electron flows in the Hall plasma, this mode is perceived by the second component as the Doppler-shifted continuously sheared mode with time-dependent wave numbers. Due to this effect, the interaction of the plasma components forms the nonmodal time-dependent process, which should be investigated as the initial value problem. The developed approach is applied to the solutions of the linear initial value problems for the hydrodynamic modified two-stream instability and the kinetic ion-sound instability of the plasma with a sheared Hall current with a uniform velocity shear. These solutions reveal that the uniform part of the current velocity is responsible for the modal evolution of the instability, whereas the current velocity shear is the source of the development of the nonmodal instability with exponent growing with time as $\sim\left(t-t_0\right)^3$.

description: Colonial predicament made life and its understanding complex in the Subcontinent. To represent this complexity, Urdu writers found the polyphonic genre novel helpful. They used different techniques of characterization to narrate the social hierarchy of characters. The novel also provided the space for them to attract people by encapsulating the residual sensibility of conventional love of Urdu poetry and at the same time launch their ideas of reform to accommodate the changing world. This article presents an analysis of Sharar's Dilchasp and argues that he used the novelistic genre to represent his hierarchized social milieu, cultural norms, and reformative agenda.

Worlds in the Everett Interpretation

description: This is a discussion of how we can understand the world-view given to us by the Everett interpretation of quantum mechanics, and in particular the role played by the concept of `world'. The view presented is that we are entitled to use `many-worlds' terminology even if the theory does not specify the worlds in the formalism; this is defended by means of an extensive analogy with the concept of an `instant' or moment of time in relativity, with the lack of a preferred foliation of spacetime being compared with the lack of a preferred basis in quantum theory. Implications for identity of worlds over time, and for relativistic quantum mechanics, are discussed.
