description: A model of self-driven particles similar to the Vicsek model [Phys. Rev. Lett. 75 (1995) 1226] but with metric-free interactions is studied by means of a novel Enskog-type kinetic theory. In this model, N particles of constant speed v0 try to align their travel directions with the average direction of a fixed number of closest neighbors. At strong alignment a global flocking state forms. The alignment is defined by a stochastic rule, not by a Hamiltonian. The corresponding interactions are of genuine multi-body nature. The theory is based on a Master equation in 3N-dimensional phase space, which is made tractable by means of the molecular chaos approximation. The phase diagram for the transition to collective motion is calculated and compared to direct numerical simulations. A linear stability analysis of a homogeneous ordered state is performed using the kinetic but not the hydrodynamic equations in order to achieve high accuracy. In contrast to the regular metric Vicsek-model no instabilities occur. This confirms previous direct simulations that for Vicsek-like models with metric-free interactions, there is no formation of density bands and that the flocking transition is continuous.

description: The 3D structure of solar wind and its evolution in time is needed for heliospheric modeling and interpretation of energetic neutral atoms observations. We present a model to retrieve the solar wind structure in heliolatitude and time using all available and complementary data sources. We determine the heliolatitude structure of solar wind speed on a yearly time grid over the past 1.5 solar cycles based on remote-sensing observations of interplanetary scintillations, in situ out-of-ecliptic measurements from Ulysses, and in situ in-ecliptic measurements from the OMNI-2 database. Since the in situ information on the solar wind density structure out of ecliptic is not available apart from the Ulysses data, we derive correlation formulae between solar wind speed and density and use the information on the solar wind speed from interplanetary scintillation observations to retrieve the 3D structure of solar wind density. With the variations of solar wind density and speed in time and heliolatitude available we calculate variations in solar wind flux, dynamic pressure and charge exchange rate in the approximation of stationary H atoms.

Search for anomalous t t-bar production in the highly-boosted all-hadronic final state

Year: 2012
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search is presented for a massive particle, generically referred to as a Z', decaying into a t t-bar pair. The search focuses on Z' resonances that are sufficiently massive to produce highly Lorentz-boosted top quarks, which yield collimated decay products that are partially or fully merged into single jets. The analysis uses new methods to analyze jet substructure, providing suppression of the non-top multijet backgrounds. The analysis is based on a data sample of proton-proton collisions at a center-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 5 inverse femtobarns. Upper limits in the range of 1 pb are set on the product of the production cross section and branching fraction for a topcolor Z' modeled for several widths, as well as for a Randall--Sundrum Kaluza--Klein gluon. In addition, the results constrain any enhancement in t t-bar production beyond expectations of the standard model for t t-bar invariant masses larger than 1 TeV.

description: Mit dem 9-Euro-Ticket wollte die Bundesregierung im Sommer 2022 die Menschen einerseits finanziell von den stark gestiegenen Energiepreisen entlasten und andererseits zum Umstieg auf den Öffentlichen Personennahverkehr (ÖPNV) motivieren. Um die Auswirkungen des deutschlandweit gültigen Tickets auf Mobilität und Nutzung des ÖPNV zu analysieren, werden in diesem Wochenbericht erstmalig die Bewegungsdaten eines bundesweit repräsentativen Mobilitäts- Trackings-Panels mit Informationen aus Befragungen in den Gültigkeitsmonaten zusammengeführt. Die Ergebnisse zeigen, dass das 9-Euro-Ticket nicht zu einem Umstieg hin zum ÖPNV in der Alltagsmobilität führte. Stattdessen entlastete das Ticket Personen finanziell, die den ÖPNV auch ohne das Angebot regelmäßig nutzen. Insbesondere profitierten Haushalte mit niedrigem Einkommen sowie junge Menschen unter 30 Jahren. Außerdem wurde das Ticket kurz nach seiner Einführung sowie kurz vor seinem Ende intensiv im Ausflugsverkehr genutzt. Um die Rolle des ÖPNV dauerhaft zu stärken, reichen günstige Ticketangebote nicht aus. Vielmehr muss das Angebot an öffentlichen Verkehrsmitteln ausgebaut und verbessert werden, um die Akzeptanz des ÖPNV in der Bevölkerung zu steigern.

description: For a locally compact group G, let A(G) denote its Fourier algebra, and let M_0A(G) denote the space of completely bounded Fourier multipliers on G. The group G is said to have the Approximation Property (AP) if the constant function 1 can be approximated by a net in A(G) in the weak-* topology on the space M_0A(G). Recently, Lafforgue and de la Salle proved that SL(3,R) does not have the AP, implying the first example of an exact discrete group without it, namely SL(3,Z). In this paper we prove that Sp(2,R) does not have the AP. It follows that all connected simple Lie groups with finite center and real rank greater than or equal to two do not have the AP. This naturally gives rise to many examples of exact discrete groups without the AP.

description: An experimentally feasible scheme for generating a 12-qubit hyperentangled state via four photons, entangled in polarization, frequency and spatial mode, is proposed. We study the nature of quantum non-locality of this hyperentangled state by evaluating its violation degree to a Bell-type inequality, and find that the result agrees well with quantum mechanics prediction while extremely contradicts to the local realism constraint.

description: It is widely believed that the emergent magnetic gauge symmetry of SQCD is analogous to a hidden local symmetry (HLS). We explore this idea in detail, deriving the entire (spontaneously broken) magnetic theory by applying the HLS formalism to spontaneously broken SU(N) SQCD. We deduce the Kähler potential in the HLS description, and show that gauge and flavour symmetry are smoothly restored along certain scaling directions in moduli space. We propose that it is these symmetry restoring directions, associated with the R-symmetry of the theory, that allow full Seiberg duality. Reconsidering the origin of the magnetic gauge bosons as the rho-mesons of the electric theory, colour-flavour locking allows a simple determination of the parameter "a". Its value continuously interpolates between a=2 on the baryonic branch of moduli space - corresponding to "vector meson dominance" - and a=1 on the mesonic branch. Both limiting values are consistent with previous results in the literature. The HLS formalism is further applied to SO and Sp groups, where the usual Seiberg duals are recovered, as well as adjoint SQCD. Finally we discuss some possible future applications, including (naturally) the unitarisation of composite W scattering, blended Higgs/technicolour models, real world QCD and non-supersymmetric dualities.

description: In this paper, the non-Markovian quantum dynamics of a coupled $N$-cavity model is studied based on the quantum state diffusion (QSD) approach. The time-local Diósi-Gisin-Strunz equation and the corresponding exact master equation are derived for the model consisting of a coupled cavity array. The resulting QSD equation serves as a stochastic solution to a genuine $N$-partite continuous-variable (CV) system. Several non-Markovian effects are studied in two interesting examples -- two-cavity and three-cavity, under different boundary conditions. We have shown that the environment-memory can facilitate the cat-like state transfer from one cavity to another in the case of a strongly non-Markovian environment.

description: Das Jahr 2020 war durch eine sprunghafte Zunahme der Teilnahme von Privatpersonen am Aktienmarkt gekennzeichnet. Parallel waren auch deutlich mehr Erwerbstätige im Homeoffice. Tatsächlich ist die Nutzung von Homeoffice eine robuste Bestimmungsgröße für Aktienbesitz und erklärt einen Teil des Anstiegs im Jahr 2020. Vom Homeoffice profitieren in dieser Hinsicht vor allem Personen ohne Kinder im Haushalt. Ferner kommt es gerade auch bei einkommensschwächeren Personen im Homeoffice zu einem höheren Anteil von Aktienbesitz. Das stärker genutzte Homeoffice hat damit auch komplexe verteilungspolitische Folgen. Tendenziell verbreitert es die Basis des Aktienbesitzes durch – im weiteren Sinn – sinkende Kosten der Teilnahme am Aktienmarkt. Natürlich sollte die Wirtschaftspolitik nicht Homeoffice verordnen, um den Aktienbesitz zu steigern, aber sie kann den Einstieg in den Aktienmarkt auf andere Weise erleichtern, insbesondere durch bessere finanzielle Bildung.

description: We investigate the relevant gluon-momentum region for confinement in lattice QCD on $16^4$ at $β$=5.7, 5.8 and 6.0, based on the Fourier expansion. We find that the string tension $σ$, i.e., the confining force, is almost unchanged even after removing the high-momentum gluon component above 1.5GeV in the Landau gauge. In fact, the confinement property originates from the low-momentum gluon component below 1.5GeV, which is the upper limit to contribute to $σ$. In the relevant region, smaller gluon momentum component is more important for confinement. Next, we develop a manifestly gauge-covariant expansion of the QCD operator such as the Wilson loop, using the eigen-mode of the QCD Dirac operator $γ^μD^μ$. With this method, we perform a direct analysis of the correlation between confinement and chiral symmetry breaking in lattice QCD on $6^4$ at $β$=5.6. As a remarkable fact, the confinement force is almost unchanged even after removing the low-lying Dirac modes, which are responsible to chiral symmetry breaking. This indicates that one-to-one correspondence does not hold for between confinement and chiral symmetry breaking in QCD.

description: Majorana fermions are the only fermionic particles that are expected to be their own antiparticles. While elementary particles of the Majorana type were not identified yet, quasi-particles with Majorana like properties, born from interacting electrons in the solid, were predicted to exist. Here, we present thorough experimental studies, backed by numerical simulations, of a system composed of an aluminum superconductor in proximity to an indium arsenide nanowire, with the latter possessing strong spin-orbit coupling. An induced 1d topological superconductor - supporting Majorana fermions at both ends - is expected to form. We concentrate on the characteristics of a distinct zero bias conductance peak (ZBP), and its splitting in energy, both appearing only with a small magnetic field applied along the wire. The ZBP was found to be robustly tied to the Fermi energy over a wide range of system parameters. While not providing a definite proof of a Majorana state, the presented data and the simulations support strongly its existence.

description: We introduce a variant of the slice spectral sequence which uses only regular slice cells, and state the precise relationship between the two spectral sequences. We analyze how the slice filtration of an equivariant spectrum that is concentrated over a normal subgroup is related to the slice filtration of its geometric fixed points, and use this to prove a conjecture of Hill on the slice filtration of an Eilenberg MacLane spectrum. We also show how the (co)connectivity of a spectrum results in the (co)connectivity of its slice tower, demonstrating the "efficiency" of the slice spectral sequence.

Peripheral plasticity after spinal cord injury and ramifications for cardiovascular function
Creators: name: Ramer, Leanne Margaret
Publisher: name: University of British Columbia
Year: 2012

description: Cardiovascular problems create life-long challenges for people living with spinal cord injury (SCI). When SCI occurs above the sixth thoracic segment (T6), it isolates spinal circuitry governing the critical splanchnic vascular bed, and creates the conditions for autonomic dysreflexia (AD), episodic hypertension instigated by sensory stimulation below the level of SCI. Most experiments investigating mechanisms of AD describe plasticity in the injured spinal cord. In this dissertation, I examined injury-induced changes at two peripheral loci critical to AD, the dorsal root ganglion (DRG) and mesenteric arteries. I used adult Wistar rats and performed complete transection SCI at T3 or T10: while both injuries produce hind limb paralysis, only the former is accompanied by AD. In the DRG, I found that T3 SCI triggered somatic hypertrophy in a specific subset of nociceptors, those expressing the capsaicin receptor (TRPV1). SCI-induced hypertrophy occurred in DRGs caudal to SCI and was most pronounced in lumbosacral ganglia. Intriguingly, SCI-induced hypertrophy was much more pronounced after T3 than T10 SCI. Importantly, when I used capsaicin to selectively eliminate TRPV1-positive projections to the lumbosacral spinal cord, the severity of AD was dramatically reduced. Next I examined glial, immune and vascular constituents of the lumbar DRG following SCI. I found that T3, but not T10 SCI activated satellite cells and macrophages in the DRG, and provoked mast cell accumulation in the adjacent spinal nerve. SCI at both levels promoted angiogenesis in the DRG and ingrowth of sympathetic ganglionic axons. In the superior mesenteric artery (SMA), I used in vitro myography to examine the role of cyclooxygenase (COX) enzymes in phenylephrine (PE) hyper-responsiveness after T3 SCI. I found that PE hypersensitivity was reversed by specific inhibitors of COX-2 and that COX-2 was upregulated in the SMA after T3 SCI. In an additional set of experiments, I found that recurrent episodes of AD, induced intentionally during recovery from SCI, exacerbated PE hyper-responsiveness in the SMA. These findings identify SCI-induced changes in the periphery that may contribute to AD by augmenting sensory input to the spinal cord or sympathetically-mediated vasoconstriction. These SCI-provoked effects may represent new therapeutic targets to treat AD.

description: The nucleation and growth of point islands during submonolayer deposition on a one-dimensional substrate is simulated for critical island size $i=0,1,2,3$. The small and large size asymptotics for the gap size and capture zone distributions (GSD and CZD) are studied. Comparisons to theoretical predictions from fragmentation equation analyses are made, along with those from the recently proposed Generalised Wigner Surmise (GWS). We find that the simulation data can be fully understood in the framework provided by the fragmentation equations, whilst highlighting the theoretical areas that require further development. The GWS works well for the small-size CZD behaviour, but completely fails to describe the large-size CZD asymptotics of the one-dimensional system.

description: In a class of frustrated magnets known as spin ice, magnetic monopoles emerge as classical defects and interact via the magnetic Coulomb law. With quantum-mechanical interactions, these magnetic charges are carried by fractionalised bosonic quasi-particles, spinons, which can undergo Bose-Einstein condensation through a first-order transition via the Higgs mechanism. Here, we report evidence of a Higgs transition from a magnetic Coulomb liquid to a ferromagnet in single-crystal Yb2Ti2O7. Polarised neutron-scattering experiments show that the diffuse [111]-rod scattering and pinch-point features which develop on cooling are suddenly suppressed below T_C ~ 0.21 K, where magnetic Bragg peaks and a full depolarisation of the neutron spins are observed with thermal hysteresis, indicating a first-order ferromagnetic transition. Our results are explained on the basis of a quantum spin-ice model, whose high-temperature phase is effectively described as a magnetic Coulomb liquid, while the ground state shows a nearly collinear ferromagnetism with gapped spin excitations.

Dieser Bericht geht auf Basis von Daten des Sozio-oekonomischen Panels (SOEP) der Frage nach, welchen Einfluss die Arbeitslosigkeit von Eltern in der Grundschulphase ihrer Kinder auf deren Bildungsergebnisse hat. Dafür werden Bildungsverläufe von Kindern, von denen ein Elternteil während der Grundschulphase arbeitslos wurde, mit Bildungsverläufen von Kindern, deren Eltern nicht arbeitslos waren, verglichen. Da diese Gruppen grundsätzlich sehr unterschiedlich sind, wird vorher eine Vergleichsgruppe aus statistisch betrachtet ähnlichen Familien gebildet. Ein zentrales Ergebnis ist, dass Kinder deutlich seltener (Fach-)Abitur machen und ein Studium abschließen, wenn während ihrer Grundschulzeit ein Elternteil arbeitslos war. Aufgrund ihrer Methode liefert die Studie starke Indizien dafür, dass die gemessenen Effekte kausal zu interpretieren sind, die Arbeitslosigkeit der Eltern also tatsächlich die Ursache ist. Damit zeigt sich einmal mehr, dass Bildungsverläufe in Deutschland sehr von der wirtschaftlichen und gesellschaftlichen Situation der Eltern abhängen.

description: We construct explicit solutions to continuous motion of discrete plane curves described by a semi-discrete potential modified KdV equation. Explicit formulas in terms the $τ$ function are presented. Bäcklund transformations of the discrete curves are also discussed. We finally consider the continuous limit of discrete motion of discrete plane curves described by the discrete potential modified KdV equation to motion of smooth plane curves characterized by the potential modified KdV equation.

description: We perform a general study of the thermodynamic properties of static electrically charged black hole solutions of nonlinear electrodynamics minimally coupled to gravitation in three space dimensions. The Lagrangian densities governing the dynamics of these models in flat space are defined as arbitrary functions of the gauge field invariants, constrained by some requirements for physical admissibility. The exhaustive classification of these theories in flat space, in terms of the behaviour of the Lagrangian densities in vacuum and on the boundary of their domain of definition, defines twelve families of admissible models. When these models are coupled to gravity, the flat space classification leads to a complete characterization of the associated sets of gravitating electrostatic spherically symmetric solutions by their central and asymptotic behaviours. We focus on nine of these families, which support asymptotically Schwarzschild-like black hole configurations, for which the thermodynamic analysis is possible and pertinent. In this way, the thermodynamic laws are extended to the sets of black hole solutions of these families, for which the generic behaviours of the relevant state variables are classified and thoroughly analyzed in terms of the aforementioned boundary properties of the Lagrangians. Moreover, we find universal scaling laws (which hold and are the same for all the black hole solutions of models belonging to any of the nine families) running the thermodynamic variables with the electric charge and the horizon radius. These scale transformations form a one-parameter multiplicative group, leading to universal "renormalization group"-like first-order differential equations. The beams of characteristics of these equations generate the full set of black hole states associated to any of these gravitating nonlinear electrodynamics...

description: Ultracold and quantum degenerate gases held near conductive surfaces can serve as sensitive, high resolution, and wide-area probes of electronic current flow. Previous work has imaged transport around grain boundaries in a gold wire by using ultracold and Bose-Einstein condensed atoms held microns from the surface with an atom chip trap. We show that atom chip microscopy may be applied to useful purpose in the context of materials exhibiting topologically protected surface transport. Current flow through lithographically tailored surface defects in topological insulators (TI)---both idealized and with the band-structure and conductivity typical of Bi$_{2}$Se$_{3}$---is numerically calculated. We propose that imaging current flow patterns enables the differentiation of an ideal TI from one with a finite bulk--to--surface conductivity ratio, and specifically, that the determination of this ratio may be possible by imaging transport around trenches etched into the TI's surface.

description: The establishment of nonlocal correlations, obtained through the violation of a Bell inequality, is not only important from a fundamental point of view, but constitutes the basis for device-independent quantum information technologies. Although several nonlocality tests have been performed so far, all of them suffered from either the locality or the detection loopholes. Recent studies have suggested that the use of atom-photon entanglement can lead to Bell inequality violations with moderate transmission and detection efficiencies. In this paper we propose an experimental setup realizing a simple atom-photon entangled state that, under realistic experimental parameters available to date, achieves a significant violation of the Clauser-Horn-Shimony-Holt inequality. Most importantly, the violation remains when considering typical detection efficiencies and losses due to required propagation distances.

description: Aufgrund des Klimawandels kommt es häufiger zu Stürmen, Überschwemmungen und anderen Naturkatastrophen. Die vorliegende empirische Analyse zeigt, dass eine bessere Integration von Ländern in internationale Finanzmärkte die gesamtwirtschaftlichen Abwehrkräfte gegen solche Schocks stärkt. Die Produktion ist nach einer Naturkatastrophe in Volkswirtschaften, die über Auslandsforderungen und -verbindlichkeiten stark mit anderen Finanzmärkten verflochten sind, signifikant höher als in weniger integrierten Volkswirtschaften. Die empirischen Ergebnisse legen nahe, dass die Finanzierung über ausländisches Eigenkapital und auch Investitionen in ausländische Anleihen eine schnellere Erholung begünstigen. Fremdkapital aus dem Ausland kann hingegen die Erholung nach einer Naturkatastrophe bremsen. Dieser Befund unterstreicht trotz aller Vorbehalte gegen zu starke Abhängigkeiten die Vorteile globaler Verflechtungen der Finanzmärkte, die vor allem dann stabilisierend wirken können, wenn sie diversifiziert und auf Eigenkapital ausgerichtet sind. Dies sollte die Europäische Kommission berücksichtigen, wenn sie die dringend erforderliche Kapitalmarktunion vorantreibt.

description: 77Se and 87Rb nuclear magnetic resonance (NMR) experiments on Rb0.74Fe1.6Se2 reveal clearly distinct spectra originating from a majority antiferromagnetic (AF) and a minority metallic-superconducting (SC) phase. The very narrow NMR line of the SC phase evidences the absence of Fe vacancies and any trace of AF order. The Rb content of the SC phase is deduced from intensity measurements identifying Rb0.3(1)Fe2Se2 as the actual composition of the SC fraction. The resulting estimate of 0:15 electrons/Fe brings this class of superconductors 245 family closer to the other Fe-based superconductor families.

description: The generalized Zakharov-Shabat systems with complex-valued non-regular Cartan elements and the systems studied by Caudrey, Beals and Coifman (CBC systems) and their gauge equivalent are studied. This study includes: the properties of fundamental analytical solutions (FAS) for the gauge-equivalent to CBC systems and the minimal set of scattering data; the description of the class of nonlinear evolutionary equations, solvable by the inverse scattering method, and the recursion operator, related to such systems; the hierarchies of Hamiltonian structures. The results are illustrated on the example of the multi-component nonlinear Schrodinger (MNLS) equations and the corresponding gauge-equivalent multi-component Heisenberg ferromagnetic (MHF) type models, related to so(5;C) algebra.

Rediscovering the meaning of John 6:53 : the two ways, the Lord's ambivalent table, and mimetic theory
Creators: name: Barber, Peter John
Publisher: name: University of British Columbia
Year: 2012

description: The focus of this thesis is the meaning of John 6:53: “So Jesus said to them, ‘Very truly, I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you’” (NRSV). This verse is the crux interpretum of John 6:51-58, and of the midrash this passage concludes (John 6:31-58). It is also a verse that many Johannine scholars agree remains to be understood in context. The verse expresses language of sanctioned violence and cannibalism, language of gaining life through devouring a fellow mortal. Should Jesus’ statement be taken literally, metaphorically, or both? Does Jesus refer only to himself with the term ‘son of Man’, or to mortals generally, or both? Does the literary background alluded to in this verse and its context shed light on these questions? The close and broad socio-literary contexts should help the reader with these interpretive decisions. René Girard’s anthropology of violence and religion was formed to address the matter of sanctioned violence and the language used to articulate it. It is therefore the tool employed here, in combination with the subverted combat myth tradition of the Hebrew Bible, to address the question of the intended meaning of John 6:53. Reading through the lens of mimetic theory, I propose that this verse as part of a Passover midrash expresses a contrast of two types of modus vivendi (e.g. John 6:27), or the biblical theme of the ‘two ways’. These ways complement two types of ‘imitation’ for gaining ‘being’ as described by Girard’s mimetic theory: internal mimesis as a way of death, and external mimesis as a way of life. In John 6:53, Jesus describes both ways in one breath as part of a test for his audience.
