description: We show that ultracold chemical reactions can be manipulated and controlled by using Rydberg-dressed interactions. Scattering in the ultracold regime is sensitive to long-range interactions, especially when weakly bound (or quasi-bound) states exist near the collision threshold. We investigate how, by Rydberg-dressing a reactant, one enhances its polarizability and modifies the long-range van der Waals collision complex, which can alter chemical reaction rates by shifting the position of near threshold bound states. We carry out a full quantum mechanical scattering calculation for the benchmark system H$_2$+D, and show that resonances can be moved substantially and that rate coefficients at cold and ultracold temperatures can be increased by several orders of magnitude.

description: Some flavor SU(3) results are presented for decays of the $Λ_b$ baryon into non-charmed final states $PB$, where $P$ is a pseudoscalar mesons and $B$ is a spin-1/2 baryon. Although these relations are among amplitudes and hence not yet subject to direct experimental test, they can form the basis for triangle inequalities among decay rates.

description: The conflict between vergence (eye movement) and accommodation (crystalline lens deformation) occurs in every stereoscopic display. It could cause important stress outside the "zone of comfort", when stereoscopic effect is too strong. This conflict has already been studied using questionnaires, during viewing sessions of several minutes. The present pilot study describes an experimental protocol which compares two different comfort conditions using electroencephalography (EEG) over short viewing sequences. Analyses showed significant differences both in event-related potentials (ERP) and in frequency bands power. An uncomfortable stereoscopy correlates with a weaker negative component and a delayed positive component in ERP. It also induces a power decrease in the alpha band and increases in theta and beta bands. With fast responses to stimuli, EEG is likely to enable the conception of adaptive systems, which could tune the stereoscopic experience according to each viewer.

Kelvin-Helmholtz versus Hall Magneto-shear instability in astrophysical flows

description: We study the stability of shear flows in a fully ionized plasma. Kelvin-Helmholtz is a well known, macroscopic and ideal shear-driven instability. In sufficiently low density plasmas, also the microscopic Hall magneto-shear instability can take place. We performed three-dimensional simulations of the Hall-MHD equations where these two instabilities are present, and carried out a comparative study. We find that when the shear flow is so intense that its vorticity surpasses the ion-cyclotron frequency of the plasma, the Hall magneto-shear instability is not only non-negligible, but it actually displays growth rates larger than those of the Kelvin-Helmholtz instability.

description: We consider gaugeon formulations which discuss the quantum gauge freedom covariantly in the framework of generalized BRST transformation for the Yang-Mills theory as well as the BRST invariant Higgs model. We generalize the BRST symmetries of both the Yang-Mills theory and the Higgs model by making the transformation parameter finite and field-dependent. Remarkably, we observe that the gaugeon Lagrangian which describe the quantum gauge freedom appear automatically in the effective theories along with the natural shift in gauge parameters under specific finite field-dependent parameters.

A heat bath can generate all classes of three-qubit entanglement

description: It is common knowledge that coupling to a heat bath, in general, tends to reduce the entanglement in a quantum system. In recent years, increasing interest has been devoted to the opposite situation where thermal or specifically tailored environments may stabilize or even generate entanglement. We prove the universality of this phenomenon for multipartite entanglement in the frame of an exactly solvable dephasing model. We show by evaluating analytical lower bounds for the appropriate entanglement measures that a common thermal environment can dynamically generate all entanglement classes of three qubits for almost any initial product state. For sufficiently weak dissipation this entanglement may persist up to arbitrarily large times.

New treatments of density fluctuations and recurrence times for re-estimating Zermelo's paradox

Year: 2014
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: What is the probability that all the gas in a box accumulates in the same half of this box? Though amusing, this question underlies the fundamental problem of density fluctuations at equilibrium, which has profound implementations in many physical fields. The currently accepted solutions are derived from the studies of Brownian motion by Smoluchowski, but they are not appropriate for the directly colliding particles of gases. Two alternative theories are proposed here using self-regulatory Bernoulli distributions. A discretization of space is first introduced to develop a mechanism of matter congestion holding for high densities. In a second mechanism valid in ordinary conditions, the influence of local pressure on the location of every particle is examined using classical laws of ideal gases. This approach reveals that a negative feedback results from the reciprocal influences between individual particles and the population of particles, which strongly reduces the probability of atypical microstates. Finally, a thermodynamic quantum of time is defined to compare the recurrence times of improbable macrostates predicted through these different approaches.

description: Evolving user requirements presents a considerable software engineering challenge, all the more so in an environment where data will be stored for a very long time, and must remain usable as the system specification evolves around it. Capturing the description of the system addresses this issue since a description-driven approach enables new versions of data structures and processes to be created alongside the old, thereby providing a history of changes to the underlying data models and enabling the capture of provenance data. This description-driven approach is advocated in this paper in which a system called CRISTAL is presented. CRISTAL is based on description-driven principles; it can use previous versions of stored descriptions to define various versions of data which can be stored in various forms. To demonstrate the efficacy of this approach the history of the project at CERN is presented where CRISTAL was used to track data and process definitions and their associated provenance data in the construction of the CMS ECAL detector, how it was applied to handle analysis tracking and data index provenance in the neuGRID and N4U projects, and how it will be matured further in the CRISTAL-ISE project. We believe that the CRISTAL approach could be invaluable in handling the evolution, indexing and tracking of large datasets, and are keen to apply it further in this direction.

description: We present results of new photometric observations of the contact binary system \astrobj{HI Pup} as well as the radial velocity curve of the system. Time series multicolour photometry was obtained at the South African Astronomical Observatory (SAAO) using the 1-m Cassegrain Telescope. We applied a simultaneous solution to the $BVRI$ light and radial velocity curves in order to determine the physical parameters of the system. From an analysis of the new multicolour data, the physical parameters were found to be $M_1=1.22M_{\odot}$, $M_2=0.23M_{\odot}$, $R_1=1.44R_{\odot}$, $R_2=0.67R_{\odot}$, $L_1=3.3L_{\odot}$, $L_2=0.7L_{\odot}$. Our solution confirms that HI Pup has a typical A--type W UMa binary system characteristics.

description: Universities are key sites of knowledge creation. Governments and research funders are increasingly interested in ensuring that their investments in the production of new knowledge deliver a quantifiable return on investment, including in the form of ‘impact’. Ensuring that research outputs are not locked behind paywalls, and that research data can be interrogated and built upon are increasingly central to efforts to improve the effectiveness of global research landscapes. We argue that mandating and promoting open access (OA) for published research outputs, as well as the sharing of research data are important elements of building a vibrant open knowledge system, but they are not enough. Supporting diversity within knowledge-making institutions; enabling collaboration across boundaries between universities and wider communities; and addressing inequalities in access to knowledge resources and in opportunities to contribute to knowledge making processes are also important. New tools are needed to help universities, funders, and communities to understand the extent to which a university is operating as an effective open knowledge institution; as well as the steps that might be taken to improve open knowledge performance. This presentation discusses our team’s efforts to develop a model of Open Knowledge that is not confined to measures of OA and open data. The Curtin Open Knowledge Initiative is a project of the Centre for Culture and Technology at Curtin University. With funding from the university, we are exploring the extent to which universities are functioning as effective open knowledge institutions; as well as the types of information that universities, funders, and communities might need to understand an institution’s open knowledge performance and how it might be improved. The challenges of data collection on open knowledge practices at scale, and across national, cultural and linguistic boundaries are also discussed.

description: We report a dc magnetization study of the critical phenomenon around the ferromagnetic transition temperature T_C in high-quality single crystals of uranium ferromagnetic superconductors UGe2 and URhGe. The critical exponents, beta for the temperature dependence of the magnetization below T_C, gamma for the magnetic susceptibility, and delta for the magnetic isothermal at T_C have been determined with a modified Arrott plot, a Kouvel-Fisher plot, and the scaling analysis. Magnetization in the ferromagnetic state has strong uniaxial magnetic anisotropy in the two compounds. However, the universality class of the critical phenomena do not belong to the three dimensional (3D) Ising system. Although the values of beta in UGe2 and URhGe are close to those in the 3D magnets, the values of gamma are close to unity, that expected from the mean field theory. Similar critical exponents have been reported previously for the 3D Ising ferromagnet UIr where superconductivity appears under high pressure. The critical behavior may be limited to a very narrow Ginzburg critical region of 1 mK because of the strong itinerant character of the 5f electrons in the ferromagnetic superconductor UCoGe where the mean field behavior of the magnetization has been reported. The unconventional critical scaling of magnetization in UGe2, URhGe and UIr cannot be explained via previous approaches to critical phenomena. The ferromagnetic correlation between the 5f electrons differs from that in the 3D Ising system and this difference may be a key point for the understanding of the ferromagnetism where superconductivity emerges.

Exploring the Making, Modifying, and Use of Physical Tools in Augmented Reality
Creators: name: Potts, Dominic
Publisher: name: Lancaster University
Year: 2023

description: The relationship between humans and physical tools is fundamental to all forms of work. With the proliferation of technology, the field of Human-Computer Interaction has focussed on the development of tools to interface with computers. Augmented Reality (AR) is one such technology that has gained prominence in recent years by merging physical and digital elements to enhance labour and promising more versatile and adaptive forms of work. While virtual objects provided by AR can enrich our physical environments, they remain intangible, presenting a number of challenges and opportunities for interaction. Considering this, we first argue the necessity of adopting physical tools to interact with virtual objects in AR. Second, the design of physical tools in AR can yield entirely new interaction possibilities especially when combined with the physical environment. And third, we advocate for the use of physical but versatile tools in AR, capable of modification to meet the demands of the task and user. This thesis explores Tool-making, Tool-Modifying, and Tool-Using for interacting with virtual objects in head-mounted display AR. The research includes a design space of physically-modifiable AR tools, supported by two empirical studies, and a toolkit for creating physically-modifiable cubic AR tools. We outline the surface-based touch gestures and 3D interaction techniques enabled by the cubic tools and combine them into five demonstrative AR applications. Lastly, we empirically explore and evaluate a 3D manipulation technique enabled by the toolkit. Results of the design space exploration and studies showcase how physically-modifiable AR tools can engender novel forms of interaction, alleviate common limitations of physical interfaces, and address certain interaction challenges in current AR techniques. The aim of this thesis is to stimulate fresh considerations for AR design, bringing interaction to the physical environment where humans excel, and envisioning tools as the ultimate mediators in the ultimate display.

description: We study a granular-sized magnetic flux emergence event that occurred in NOAA 11024 in July 2009. The observations were made with the CRISP spectropolarimeter at the Swedish 1 m Solar Telescope achieving a spatial resolution of 0.14". Simultaneous full Stokes observations of the two photospheric Fe I lines at 630.2 nm and the chromospheric Ca II 854.2 nm line allow us to describe in detail the emergence process across the solar atmosphere. We report here on 3D semi-spherical bubble events, where instead of simple magnetic footpoints, we observe complex semi-circular feet straddling a few granules. The most characteristic signature in these events is the observation of a dark bubble in filtergrams taken in the wings of the Ca II 854.2 nm line. We can infer how the bubble rises through the solar atmosphere as we see it progressing from the wings to the core of Ca II 854.2 nm. In the photosphere, the magnetic bubble shows mean upward Doppler velocities of 2 km/s. In about 3.5 minutes it travels some 1100 km to reach the mid chromosphere, implying an average ascent speed of 5.2 km/s. To aid the interpretation of the observations, we carry out 3D numerical simulations of the evolution of a horizontal, untwisted magnetic flux sheet injected in the convection zone, using the Bifrost code. The computational domain spans from the upper convection zone to the lower corona. In the modeled chromosphere the rising flux sheet produces a large, cool, magnetized bubble. We compare this bubble with the observed ones and find excellent agreement, including similar field strengths and velocity signals in the photosphere and chromosphere, temperature deficits, ascent speeds, expansion velocities, and lifetimes.

description: The entry discusses the commercial cinema of Pakistan. It briefly refers to the film production in the pre-Partition era, and points to the works of famous Pakistani film directors who migrated to Pakistan after the 1947-Partition, includes Dawood Chand, Shaukat Hussain Rizvi and others. The paper divides the cinema of Pakistan in to five eras, beginning with the monopoly years from 1947 to 1966, golden era from 1966 to 1977, disaster years from 1977 to 1988, deregulation and privatization from 1988 to 2001, and the decline in the first decade of the new millennium. It examines film production in East Pakistan (now Bangladesh) and West Pakistan (now Pakistan) in the post-Partition era, and points to the development of national and regional cinemas in Urdu, Bengali, Punjabi, Sinshi and Pashto languages through films like Teri Yaad (In your memory), Humari Zaban (Our language), Umar-Marvi (the names of the Sindhi protagonists), Chanvey (My dear), Nawab Sirajuddaula (a native Governor from the Mogul era), Zarqa (the name of the freedom fighter), Haseena Atom Bomb (The title of the atom bomb like beauty), and Noor-e-Islam (The light of Islam) that covered social, folk, religious and national themes. It examines how Pakistani cinema performed under different political regimes before and after the FALL/liberation of Dhaka, and covers brief discussions of films by prominent directors like Luqman, Hassan Tariq, Riaz Shahid, Qaisar Sanobar and Javaid Sheikh. It also refers to the moral decline in/decline of Pakistani film, imports from India and the production of internationally funded films like Sabiha Sumar’s Khamosh Pani (The silent waters). The paper depicts a picture of inconsistency of Pakistani cinema due to government’s negligence, price control, entertainment taxes, lack of funds, smuggling and piracy, East Pakistan separation, and banning of Indian films.

description: We investigate the connection between dust and gas in the nearby edge-on spiral galaxy NGC 891. High resolution Herschel PACS and SPIRE 70, 100, 160, 250, 350, and 500 $μ$m images are combined with JCMT SCUBA 850 $μ$m observations to trace the far-infrared/submillimetre spectral energy distribution (SED). Maps of the HI 21 cm line and CO(J=3-2) emission trace the atomic and molecular hydrogen gas, respectively. We fit one-component modified blackbody models to the integrated SED, finding a global dust mass of 8.5$\times$10$^{7}$ M$_{\odot}$ and an average temperature of 23$\pm$2 K. We also fit the pixel-by-pixel SEDs to produce maps of the dust mass and temperature. The dust mass distribution correlates with the total stellar population as traced by the 3.6 $μ$m emission. The derived dust temperature, which ranges from approximately 17 to 24 K, is found to correlate with the 24 $μ$m emission. Allowing the dust emissivity index to vary, we find an average value of $β$ = 1.9$\pm$0.3. We confirm an inverse relation between the dust emissivity spectral index and dust temperature, but do not observe any variation of this relationship with vertical height from the mid-plane of the disk. A comparison of the dust properties with the gaseous components of the ISM reveals strong spatial correlations between the surface mass densities of dust and the molecular hydrogen and total gas surface densities. Observed asymmetries in the dust temperature, and the H$_{2}$-to-dust and total gas-to-dust ratios hint that an enhancement in the star formation rate may be the result of larger quantities of molecular gas available to fuel star formation in the NE compared to the SW. Whilst the asymmetry likely arises from dust obscuration due to the geometry of the line-of-sight projection of the spiral arms, we cannot exclude an enhancement in the star formation rate in the NE side of the disk.

description: Frontier orbital analysis of two conjugated, cyclic polyenes held face-to-face in close proximity suggests that when both polyenes have 4nπ-electron systems the interaction will be stabilizing, whereas when both have (4n+2)π-electron systems the interaction will be destabilizing[¹]. To test this prediction experimentally it would be of especial interest to examine phanes having nonbenzenoid aromatic and also antiaromatic decks as model compounds.

description: The simulation of daylight in buildings of the past, based on archaeological record, and its interpretation in the context of human history is a field of interdisciplinary research. It relies on a consecutive combination of models, that emerge from different disciplines and are possibly based on diverging assumptions. Each of these models comes with its particular capabilities, limitations and uncertainties. This contribution distinguishes four major model domains: Architectural reconstruction reflects historic practice and provides a geometric representation of the evaluated building in the past. Models of building materials describe their interaction with light, e. g. scattering and absorption. They cannot just mimic the characteristics of an archaeological find but must deduce its state in the past, taking into account physical material properties and historic production methods. Environmental conditions are defined by sky models. They must reflect the luminance distribution of the sky hemisphere and can integrate effects of external occlusion and reflection. Perception models bridge the gap between the results of light simulation, e. g. in terms of radiometric or photometric quantities, and the subjective response of a human observer for the interpretation in the context of historic research. For each of these four model domains, an example is introduced and critically discussed. Structuring the interdisciplinary research along a chain of distinct models is proposed to foster the discourse between the disciplines. This shall provide a better understanding of the potential and uncertainties of daylight simulation in the research of production and perception of historic built environments.

description: Terrestrial Gamma ray Flashes (TGFs) -- very short, intense bursts of electrons, positrons, and energetic photons originating from terrestrial thunderstorms -- have been detected with satellite instruments. TETRA, an array of NaI(Tl) scintillators at Louisiana State University, has now been used to detect similar bursts of 50 keV to over 2 MeV gamma rays at ground level. After 2.6 years of observation, twenty-four events with durations 0.02- 4.2 msec have been detected associated with nearby lightning, three of them coincident events observed by detectors separated by ~1000 m. Nine of the events occurred within 6 msec and 3 miles of negative polarity cloud-to-ground lightning strokes with measured currents in excess of 20 kA. The events reported here constitute the first catalog of TGFs observed at ground level in close proximity to the acceleration site.

description: Nova Delphini 2013 was identified on the 14th of August 2013 and eventually rose to be a naked eye object. We sought to study the behaviour of the object in the run-up to outburst and to compare it to the pre-outburst photometric characteristics of other novae. We searched the Pan-STARRS 1 datastore to identify pre-outburst photometry of Nova Del 2013 and identified twenty-four observations in the 1.2 years before outburst. The progenitor of Nova Delphini showed variability of a few tenths of a magnitude but did not brighten significantly in comparison with archival plate photometry. We also found that the object did not vary significantly on the approximately half hour timescale between pairs of Pan-STARRS 1 observations.

description: We present the first successful 81Kr-Kr radiometric dating of ancient polar ice. Krypton was extracted from the air bubbles in four ~350 kg polar ice samples from Taylor Glacier in the McMurdo Dry Valleys, Antarctica, and dated using Atom Trap Trace Analysis (ATTA). The 81Kr radiometric ages agree with independent age estimates obtained from stratigraphic dating techniques with a mean absolute age offset of 6 +/- 2.5 ka. Our experimental methods and sampling strategy are validated by 1) 85Kr and 39Ar analyses that show the samples to be free of modern air contamination, and 2) air content measurements that show the ice did not experience gas loss. We estimate the error in the 81Kr ages due to past geomagnetic variability to be below 3 ka. We show that ice from the previous interglacial period (MIS 5e, 130-115 ka before present) can be found in abundance near the surface of Taylor Glacier. Our study paves the way for reliable radiometric dating of ancient ice in blue ice areas and margin sites where large samples are available, greatly enhancing their scientific value as archives of old ice and meteorites. At present, ATTA 81Kr analysis requires a 40-80 kg ice sample; as sample requirements continue to decrease 81Kr dating of ice cores is a future possibility.

description: At RHIC, a suppression, $R_{AA}\approx 0.2$ relative to binary-scaling, for $π^0$ with $5\leq p_T\leq 20$ GeV/c was discovered in central Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV, and surprisingly also for single-electrons from the decay of heavy quarks. Both these results have been confirmed in Pb+Pb collisions at the LHC at $\sqrt{s_{NN}}=2.76$ TeV. In this $p_T$ range, the LHC results for pions nearly overlap the RHIC results but the flatter spectrum at LHC implies that the energy loss in the medium must be $\sim 40$% larger than at RHIC. At LHC, the unique and beautiful measurement of the fractional transverse momentum imbalance $1-\langle{\hat{p}_{T_2}/\hat{p}_{T_1}}\rangle$ of di-jets in Pb+Pb collisions relative to p-p collisions, shows $\approx 15\%$ for jets with $120\leq\hat{p}_{T_1}\leq 360$ GeV/c. This is a much smaller fractional jet imbalance than the $\approx 45\%$ derived from two-particle correlations of di-jet fragments at RHIC corresponding to jet $\hat{p}_T\approx 10-20$ GeV/c. This presents a challenge to both theory and experiment for improved understanding. There are many other such unresolved issues, for instance, the absence of evidence for a $\hat{q}$ effect by observation of momentum transferred to the medium by outgoing partons. An implied hard scattering component for the soft physics multiplicity distributions in A+A collisions based on a popular formula, ${dN_{\rm ch}^{AA}/dη}= [(1-x) \langle{N_{\rm part}}\rangle {dN_{\rm ch}^{pp}/dη}/2 + x\, \langle{N_{\rm coll}}\rangle {dN_{\rm ch}^{pp}/dη}]$, seems to be an unphysical way to understand the deviation from $N_{\rm part}$ scaling. Based on recent p-p and d+A measurements, a more physical way is presented along with several other stimulating results and ideas from recent d+Au (p+Pb) measurements.

description: Context: Several recent studies have found that planet migration in adiabatic discs differs significantly from migration in isothermal discs. Depending on the thermodynamic conditions, i.e., the effectiveness of radiative cooling, and the radial surface density profile, planets migrate inward or outward. Clearly, this will influence the semimajor axis - mass distribution of planets as predicted by population synthesis simulations. Aims: Our goal is to study the global effects of radiative cooling, viscous torque desaturation and gap opening as well as stellar irradiation on the tidal migration of a synthetic planet population. Methods: We combine results from several analytical studies and 3D hydrodynamic simulations in a new semi-analytical migration model for the application in our planet population synthesis calculations. Results: We find a good agreement of our model with torques obtained in a 3D radiative hydrodynamic simulations. We find three convergence zones in a typical disc, towards which planets migrate from the in- and outside, affecting strongly the migration behavior of low-mass planets. Interestingly, this leads to slow type II like migration behavior for low-mass planets captured in those zones even without an ad hoc migration rate reduction factor or a yet to be defined halting mechanism. This means that the new prescription of migration including non-isothermal effects makes the preciously widely used artificial migration rate reduction factor obsolete. Conclusions: Outward migration in parts of a disc makes some planets survive long enough to become massive. The convergence zones lead to a potentially observable accumulations of low-mass planets at certain semimajor axes. Our results indicate that further studies of the mass where the corotation torque saturates will be needed since its value has a major impact on the properties of planet populations.
