description: Muon spin relaxation/rotation (muSR) is a vital technique for probing the superconducting gap structure, pairing symmetry and time reversal symmetry breaking, enabling an understanding of the mechanisms behind the unconventional superconductivity of cuprates and Fe-based high-temperature superconductors, which remain a puzzle. Very recently double layered Fe-based super-conductors having quasi-2D crystal structures and Cr-based superconductors with a quasi-1D structure have drawn considerable attention. Here we present a brief review of the characteristics of a few selected Fe- and Cr-based superconducting materials and highlight some of the major outstanding problems, with an emphasis on the superconducting pairing symmetries of these materials. We focus on muSR studies of the newly discovered superconductors ACa2Fe4As4F2(A = K, Rb, and Cs), ThFeAsN, and A2Cr3As3(A = K, Cs), which were used to determine the superconducting gap structures, the presence of spin fluctuations, and to search for time reversal symmetry breaking in the superconducting states. We also briefly discuss the results of muSR investigations of the superconductivity in hole and electron doped BaFe2As2.

Kinds of evidence for linguistic theory*
Creators: name: Belletti, Adriana
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2007
Subjects: null subject; (free) inversion/VS; que > qui; clitics; focus; discourse-related positions; weak pronouns

description: The intimate relation between general theoretical hypotheses and the empirical data which can support them is the central topic of this paper. Data from different modes of acquisition are reviewed and discussed in the light of their significance for linguistic theory. Traditionally assumed correlations of properties related to the setting of the null subject parameter, availability of post-verbal subjects and modifications on the shape of the complementizer, are reinterpreted in terms of “weak” (not necessary) and “strong” (necessary) correlations on the basis of experimental acquisition data. Paths of acquisition of French and Italian clitic pronouns in different modes of acquisition are considered revealing of the possibly different analysis that clitic pronouns can be more readily subject to in different languages.

A sequential update algorithm for computing the stationary distribution vector in upper block-Hessenberg Markov chains
Creators: name: Masuyama, Hiroyuki
Publisher: name: arXiv
Year: 2019
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: This paper proposes a new algorithm for computing the stationary distribution vector in continuous-time upper block-Hessenberg Markov chains. To this end, we consider the last-block-column-linearly-augmented (LBCL-augmented) truncation of the (infinitesimal) generator of the upper block-Hessenberg Markov chain. The LBCL-augmented truncation is a linearly-augmented truncation such that the augmentation distribution has its probability mass only on the last block column. We first derive an upper bound for the total variation distance between the respective stationary distribution vectors of the original generator and its LBCL-augmented truncation. Based on the upper bound, we then establish a series of linear fractional programming (LFP) problems to obtain augmentation distribution vectors such that the bound converges to zero. Using the optimal solutions of the LFP problems, we construct a matrix-infinite-product (MIP) form of the original (i.e., not approximate) stationary distribution vector and develop a sequential update algorithm for computing the MIP form. Finally, we demonstrate the applicability of our algorithm to BMAP/M/$\infty$ queues and M/M/$s$ retrial queues.

description: We present a spontaneously broken N=2 supergravity model that reduces in the flat limit to a globally supersymmetric N=2 system with explicit soft supersymmetry breaking terms. These soft terms generate a mass O(100 GeV) for mirror quarks and leptons, while leaving the physical fermions light, thereby overcoming one of the major obstacles towards the construction of a realistic N=2 model of elementary interactions.

Temperature dependence of the transition packing fraction of thermal jamming in a harmonic soft sphere system
Creators: name: Maiti, Moumita
name: Schmiedeberg, Michael
Publisher: name: arXiv
Year: 2018
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: The glassy dynamics of soft harmonic spheres is often mapped onto the dynamics of hard spheres by considering an effective diameter for the soft particles and therefore an effective packing fraction. While in this approach the thermal fluctuations within valleys of the energy landscape are covered, the crossing of energy barriers from one valley into another usually is neglected. Here we argue - motivated by studies of the glass transition based on explorations of the energy landscape - that the crossing of energy barriers can be attributed by an effective decrease of the glass transition packing fraction with increasing temperature T according to T^{0.2}. Furthermore, we reanalyzing data of soft sphere simulations. Since fitting scaling laws to simulation data always allows for some arbitrariness, we cannot prove based on the simulation data that our idea of a shift of the glass transition packing fraction due to barrier crossings is the only possible way to explain the discrepancies that have been observed previously. However, we show that a possible explanation of the simulation data is given by our approach to characterize the dynamics of soft spheres by both, the previously-considered temperature-dependent effective packing fraction due to the increase of the mean overlap between neighboring particles with stronger thermal fluctuations and the newly introduced increase of the glass transition packing with an increasing probability of barrier crossings.

Crosslinguistic influence in English-Greek bilingual acquisition*
Creators: name: Argyri, Efrosyni
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2007
Subjects: English-Greek bilingual acquisition; crosslinguistic influence; language dominance

description: This study tests the proposal that structures which involve the syntax-pragmatics interface and instantiate a surface overlap between the two languages are vulnerable to crosslinguistic influence in bilingual acquisition (e.g. Müller & Hulk 2001). We investigate whether crosslinguistic influence occurs only in one direction – from English to Greek, in this case – in older bilingual children. The study considers experimental data from 32 English-Greek bilingual children, 16 Greek-dominant living in Greece and 16 English-dominant living in the UK and monolingual control groups regarding particular syntax-pragmatics interface and narrow syntax structures. Results reveal that certain structures are selectively vulnerable to crosslinguistic influence but only in the English-dominant bilinguals’ grammar, which offers only partial support to the hypothesis.

description: Spontaneous formation of spatial structures (patterns) occurs in various contexts, ranging from sand dunes and rogue wave formation, to traffic jams. These last decades, very practical reasons also led to studies of pattern formation in relativistic electron bunches used in synchrotron radiation light sources. As the main motivation, the patterns which spontaneously appear during an instability increase the terahertz radiation power by factors exceeding 10000. However the irregularity of these patterns largely prevented applications of this powerful source. Here we show how to make the spatio-temporal patterns regular (and thus the emitted THz power) using a point of view borrowed from chaos control theory. Mathematically, regular unstable solutions are expected to coexist with the undesired irregular solutions, and may thus be controllable using feedback control. We demonstrate the stabilization of such regular solutions in the Synchrotron SOLEIL storage ring. Operation of these "controlled unstable solutions" enables new designs of high charge and stable synchrotron radiation sources.

Do bilinguals think differently from monolinguals? Evidence from non-linguistic cognitive categorisation of objects in Japanese-English bilinguals*
Creators: name: Athanasopoulos, Panos
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2007
Subjects: Bilingual Cognition; Second Language Acquisition; Language and Thought

description: Recent advances in the investigation of the relationship between language and cognition have demonstrated that speakers of English categorise objects based on their common shape, while speakers of Yucatec and Japanese categorise objects based on their common material (Lucy & Gaskins 2003; Imai & Mazuka 2003). The current study extends that investigation to the domain of bilingualism. Results from a cognitive categorisation task show that intermediate Japanese L2 English speakers behaved similarly to Japanese monolinguals, while advanced Japanese L2 English speakers behaved similarly to English monolinguals. The implications of these findings for bilingualism and second language acquisition are discussed.

Articles and clitics in English as L2 or L3: evidence from Greek and Turkish/Greek speakers*
Creators: name: Avgerinou, Despina
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2007
Subjects: definite/indefinite article; clitics; object pronouns; L3 acquisition

description: This paper reports on a pilot study which investigates the acquisition of English pronouns and determiners at beginner level by adolescent speakers of Greek as L1 or L2. The L2 speakers of Greek are native Turkish speakers born and educated in Greece. Testing involved tasks in English and Greek and aimed at eliciting English pronominal objects and determiners. Given that for the Turkish/Greek speakers (i) English is L3, and that (ii) Turkish lacks determiners and clitics, the acquisition of English determiners and object pronouns presents an interesting case. English lacks pronominal clitics but, unlike Turkish, it disallows null objects. Furthermore, the absence of a determiner system in Turkish and its availability in Greek and English pose an interesting question regarding the acquisition of these categories by Turkish L1 speakers, who are expected to deviate from native-like performance in the form of omission. However, knowledge of Greek L2 could, in principle, interfere with English L3 acquisition of these elements in facilitating their use. In order to answer this question, the same tasks were used with L1 Greek learners of English. The results of the data analysis shed light to the role of Greek as L1 and L2 in the acquisition of determiners and object pronouns.

Acquiring clitics and determiners in child L2 Modern Greek*
Creators: name: Chondrogianni, Vicky
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2007
Subjects: child L2 acquisition; clitics; determiners; (un)interpretable features

description: The present paper explores the acquisition of third person direct object clitics and definite determiners by Turkish-speaking child L2 learners of Modern Greek. 66 Turkish-speaking children aged 7-12 and of five different proficiency levels were administered three tasks, in order to test the production of object clitics and the definite determiner. Furthermore, the production of phi-features and case was controlled for. Preliminary results show an initial omission of the two D-elements, but a later differentiation in their acquisition pattern, as clitic drop remains robust until later stages of acquisition. At the same time a hierarchical acquisition pattern of uninterpretable features is found (case, number>gender).

description: In this paper we present results from a comprehension task regarding Greek children’s understanding of the completion entailments of the Past Perfective (Aoristos) and the Past Imperfective (Paratatikos) with creation and change-of-state predicates. Children are found to perform better in the past perfective than the past imperfective. In accordance with previous research in Russian (Kazanina & Philips 2003), the main problem lies in associating the past imperfective with incomplete events. In addition, although the children’s overall performance remains almost the same between the two types of predicates, there is a slight improvement in the past imperfective with creation predicates.

Zero Mode and Symmetry Breaking on the Light Front

description: We study the zero mode and the spontaneous symmetry breaking on the light front (LF). We use the discretized light-cone quantization (DLCQ) of Maskawa-Yamawaki to treat the zero mode in a clean separation from all other modes. It is then shown that the Nambu-Goldstone (NG) phase can be realized on the trivial LF vacuum only when an explicit symmetry-breaking mass of the NG boson $m_π$ is introduced. The NG-boson zero mode integrated over the LF must exhibit singular behavior $ \sim 1/m_π^2$ in the symmetric limit $m_π\to 0$, which implies that current conservation is violated at zero mode, or equivalently the LF charge is not conserved even in the symmetric limit. We demonstrate this peculiarity in a concrete model, the linear sigma model, where the role of zero-mode constraint is clarified. We further compare our result with the continuum theory. It is shown that in the continuum theory it is difficult to remove the zero mode which is not a single mode with measure zero but the accumulating point causing uncontrollable infrared singularity. A possible way out within the continuum theory is also suggested based on the ``$ν$ theory''. We finally discuss another problem of the zero mode in the continuum theory, i.e., no-go theorem of Nakanishi-Yamawaki on the non-existence of LF quantum field theory within the framework of Wightman axioms, which remains to be a challenge for DLCQ, ``$ν$ theory'' or any other framework of LF theory.

In this work, we focus on Tm-doped YSO, a compound that was left aside in the mid-1990s due to its rather short optical coherence lifetime. By means of time-resolved hole-burning spectroscopy, we investigate the anisotropic enhanced nuclear Zeeman effect and demonstrate deep, sub-MHz, persistent spectral hole burning under specific magnetic field orientation and magnitude. By estimating the experimental parameters corresponding to a real-scale ultrasound optical tomography setup using Tm:YSO as a spectral filter, we validate Tm:YSO as a promising compound for medical imaging in the human body.

description: We calculate the gravitational radiation produced by the coalescence of inspiraling binary neutron stars in the Newtonian regime using 3-dimensional numerical simulations. The stars are modeled as polytropes and start out in the point-mass regime at wide separation. The hydrodynamic integration is performed using smooth particle hydrodynamics (SPH) with Newtonian gravity, and the gravitational radiation is calculated using the quadrupole approximation. We have run a number of simulations varying the neutron star radii, equations of state, spins, and mass ratio. The resulting gravitational waveforms and spectra are rich in information about the hydrodynamics of coalescence, and show characteristic dependence on GM/Rc^2, the equation of state, and the mass ratio.

description: The dynamics of black hole seeds in high redshift galaxies is key to understand their ability to grow via accretion and to pair in close binaries during galactic mergers. To properly follow the dynamics of black holes we develop a physically motivated model to capture unresolved dynamical friction from stars, dark matter and gas. We first validate the model and then we use it to investigate the dynamics of seed black holes born at $z\sim9$ in dwarf proto-galaxies. We perform a suite of zoom cosmological simulations with spatial resolution as high as 10 pc and with a stellar and dark matter mass resolution of $2\times10^3 \, \textrm{M}_\odot$ and $2\times10^5 \, \textrm{M}_\odot$ respectively. We first explore the dynamics of a seed black hole in the galaxy where it is born and show that it is highly erratic if the seed mass is less than $10^5\, \textrm{M}_\odot$. The dynamics is dominated by the stellar component, whose distribution is irregular and patchy, thus inducing stochasticity in the orbits: the black hole may be anywhere in the proto-galaxy. When this dwarf merges into a larger galaxy, it is paramount to simulate the process with very high spatial and mass resolution in order to correctly account for the stripping of the stellar envelope of the satellite black hole. The outcome of the encounter could be either a tight binary or, at least temporary, a wandering black hole, leading to multiple black holes in a galaxy, each inherited from a different merger.

Subjects: voice morphology; verb reading; [+/-animate] syntactic subject; apo-phrase

description: Active and non-active morphology in Greek does not always correspond with active and passive readings in a one-to-one fashion. In addition, the ‘apo-phrase’ is found in various syntactic contexts. This paper investigates how voice morphology, verb reading and animacy of the syntactic subject interact with the reading of ‘apo-phrases’ produced by Greek Native Speakers. Data, obtained through a Sentence Completion Task, show a general preference for the ‘cause’ reading of the ‘apo-phrase’ and an interaction of voice morphology, verb class and animacy of the syntactic subject on the status of the produced apo-phrase.

description: The role of background in bosonic quantum statistics is discussed in the frame of a new approach in terms of coherent states. Bosons are indeed detected in different physical situations where they exhibit different and apparently unconnected properties. Besides Bose gas we consider bosons in particle physics and bosons in harmonic traps. In particle physics bosons are dealt with in a context where the number of observed particles is finite: here the relevant features are the canonical commutation relations, which we shall show to be related to a Boltzmann-like distribution. A further case is Bose condensate in harmonic traps, where discrete spectrum leads us to predict, below T_c, a new critical temperature. The unified approach proposed shows that all defferences can be ascribed to the environment.

description: Dilatonic Charged Nariai instantons mediate the nucleation of black hole pairs during extended chaotic inflation. Depending on the dilaton and inflaton fields, the black holes are described by one of two approximations in the Lorentzian regime. For each case we find Euclidean solutions that satisfy the no boundary proposal. The complex initial values of the dilaton and inflaton are determined, and the pair creation rate is calculated from the Euclidean action. Similar to standard inflation, black holes are abundantly produced near the Planck boundary, but highly suppressed later on. An unusual feature we find is that the earlier in inflation that the dilatonic black holes are created, the more highly charged they can be.

description: The 56 tonne high resolution liquid scintillation calorimeter KARMEN at the beam stop neutrino source ISIS has been used to search for neutrino oscillations in the disappearance channel nu_e->x. The nu_e emitted in mu+ decay at rest are detected with spectroscopic quality via the exclusive charged current reaction 12-C(nu_e,e-)12-N_g.s. almost free of background. Analysis of the spectral shape of e- from the nu_e induced reaction as well as a measurement of the absolute nu_e flux allow to investigate oscillations of the type nu_e->nu_tau and nu_e->nu_mu . The flux independent ratio R(CC/NC) of charged current events 12-C(nu_e,e-)12-N_g.s. to neutral current events 12-C(nu,nu')12-C* provides additional information in the oscillation channel nu_e->x . All three analysis methods show no evidence for oscillations. For the nu_e->nu_tau channel 90%CL limits of sin^2(2t)<0.338 for dm^2>100eV^2 and dm^2<0.77eV^2 for maximal mixing in a simple 2 flavor oscillation formalism are derived. A complete 3 flavor analysis of the experimental data from five years of measurement with respect to nu_enu_tau and nu_enu_mu mixing is presented.

Theory of Light Quarks in the Confining Vacuum

description: The light quark propagation in the confining vacuum, described by an (infinite) set of gauge-invariant vacuum correlators, is studied in detail. To keep gauge invariance at each step the system of light quark and heavy antiquark is considered, and the nonlinear equations are written explicitly for the quark propagator in the limit of large $N_c$. For the lowest (Gaussian) correlator the system is studied in various approximations, and the relativistic WKB method is used to demonstrate the scalar confining interaction of light quarks, which implies chiral symmetry breaking. The chiral condensate is estimated by the relativistic WKB method, and connection to the density of global zero modes is clarified. The higher even order correlators are shown to yield the same properties of scalar confining interaction for light quarks. No attempt was made to solve the obtained nonlinear equations numerically, but the qualitative conclusion on connection between confinement and chiral symmetry breaking is drawn, and an estimate of the chiral condensate is performed.

description: We investigate the internal structure of a polymer during collapse from an expanded coil to a compact globule. Collapse is more probable in local regions of high curvature, so a smoothing of the fractal polymer structure occurs that proceeds systematically from the shortest to the longest length scales. A proposed universal scaling relationship is tested by comparison with Monte Carlo simulations. We speculate that the universal form applies to various fractal systems with local processes that promote smoothness over time. The results complement earlier work showing that on the macroscale polymer collapse proceeds by driven diffusion of the polymer ends.

Coherence and Partial Coherence in Interacting Electron Systems

description: We study coherence of electron transport through interacting quantum dots and discuss the relation of the coherent part to the flux-sensitive conductance for three different types of Aharonov-Bohm interferometers. Contributions to transport in first and second order in the intrinsic line width of the dot levels are addressed in detail. We predict an asymmetry of the interference signal around resonance peaks as a consequence of incoherence associated with spin-flip processes. Furthermore, we show by strict calculation that first-order contributions can be partially or even fully coherent. This contrasts with the sequential-tunneling picture which describes first-order transport as a sequence of incoherent tunneling processes.

description: We consider space-times with two isometries which represent gravitational waves with distinct wavefronts which propagate into exact Friedmann-Robertson-Walker (FRW) universes. The geometry of possible wavefronts is analysed in detail in all three types of FRW models. In the spatially flat and open universes, the wavefronts can be planar or cylindrical; in the closed case they are toroidal. Exact solutions are given which describe gravitational waves propagating into the FRW universes with a fluid with a stiff equation of state. It is shown that the plane-fronted waves may include impulsive or step (shock) components, while the cylindrical waves in the spatially flat and open universes and the toroidal waves in closed universes may contain steps. In general, wavefronts may exist which have an arbitrary finite degree of smoothness. In all cases, the waves are backscattered. The head-on collision of such waves is also briefly mentioned.

Pion and Kaon Polarizabilities and Radiative Transitions

description: CERN COMPASS plans measurements of gamma-pi and gamma-K interactions using 50-280 GeV pion (kaon) beams and a virtual photon target. Pion (kaon) polarizabilities and radiative transitions will be measured via Primakoff effect reactions such as pi+gamma->pi'+gamma and pi+gamma->meson. The former can test a precise prediction of chiral symmetry; the latter for pi+gamma->a1(1260) is important for understanding the polarizability. The radiative transition of a pion to a low mass two-pion system, pi+gamma->pi+pi0, can also be studied to measure the chiral anomaly amplitude F(3pi) (characterizing gamma->3pi), arising from the effective Chiral Lagrangian. We review here the motivation for the above physics program. We describe the beam, target, detector, and trigger requirements for these experiments. We also describe FNAL SELEX attempts to study related physics via the interaction of 600 GeV pions with target electrons. Data analysis in progress aims to identify the reactions pi+e->pi'+e'+pi0 related to the chiral anomaly, and pi+e->pi'+e'+gamma related to pion polarizabilities.

Non-k-diagonality in the interlayer pair-tunneling model of high-temperature superconductivity

description: We investigate the effect of k-space broadening of the interlayer pairing kernel on the critical temperature T_c and the k-dependence of the gap function in a one-dimensional version of the interlayer pair-tunneling model of high-T_c superconductivity. We consider constant as well as k-dependent intralayer pairing kernels. We find that the sensitivity to k-space broadening is larger the smaller the width of the peak of the Fermi-level gap calculated for zero broadening. This width increases with the overall magnitude of the interlayer tunneling matrix element, and decreases with the bandwidth of the single-electron intralayer excitation spectrum. The width also increases as the Fermi level is moved towards regions where the excitation spectrum flattens out. We argue that our qualitative conclusions are valid also for a two-dimensional model. This indicates that at or close to half-filling in two dimensions, when the Fermi-surface gap for zero broadening attains its peaks at $(\pm π/a,0)$ and $(0,\pmπ/a)$ where the excitation spectrum is flat, these peaks should be fairly robust to moderate momentum broadening.

Sensitivity of nuclear statistical equilibrium to nuclear uncertainties during stellar core collapse

description: I have systematically investigated the equations of state (EOSs) in nuclear statistical equilibrium under thermodynamic conditions relevant for core collapse of massive stars by varying the bulk properties of nuclear matter, the mass data for neutron-rich nuclei, and the finite-temperature modifications of the nuclear model. It is found that the temperature dependence of the nuclear free energies has a significant impact on the entropy and nuclear composition, which affect the dynamics of core-collapse supernovae. There is a little influence from the bulk properties and the mass data. For all models, common nuclei that are likely to contribute to core-deleptonization are those near $Z\approx30$ and $N\approx50$. A model with a semi-empirical expression for internal degrees of freedom, however, overestimates the number densities of magic nuclei with $N\approx50$ and $82$, while a model, in which nuclear shell effects are not considered, underestimates the number densities of heavy nuclei, and especially of the magic nuclei. Other models, which include the temperature dependence of shell effects in the internal degrees of freedom and/or in the nuclear internal free energy, indicate that the difference in population between magic nuclei and non-magic nuclei disappears as the temperature increases. The construction of complete statistical EOS will require further theoretical and experimental studies of medium-mass, neutron-rich nuclei with proton numbers 25-45 and neutron numbers 40-85.
