Determination of the ratio of $b$-quark fragmentation fractions $f_s/f_d$ in $pp$ collisions at $\sqrt{s}=7$ TeV with the ATLAS detector
Creators: name: ATLAS Collaboration

description: With an integrated luminosity of 2.47 fb$^{-1}$ recorded by the ATLAS experiment at the LHC, the exclusive decays $B_{s}^{0}\rightarrow J/ψϕ$ and $B_{d}^{0}\rightarrow J/ψK^{*0}$ of $B$ mesons produced in $pp$ collisions at $\sqrt{s}=7$ TeV are used to determine the ratio of fragmentation fractions $f_s/f_d$. From the observed $B_{s}^{0}\rightarrow J/ψϕ$ and $B_{d}^{0}\rightarrow J/ψK^{*0}$ yields, the quantity $\frac{f_s}{f_d}\frac{\mathcal{B}(B_{s}^{0} \rightarrow J/ψϕ)}{\mathcal{B}(B_{d}^{0} \rightarrow J/ψK^{*0})}$ is measured to be 0.199 $\pm$ 0.004(stat) $\pm$ 0.008(sys). Using a recent theory prediction for $\frac{\mathcal{B}(B_{s}^{0}\rightarrow J/ψϕ)}{\mathcal{B}(B_{d}^{0}\rightarrow J/ψK^{*0})}$ yields $\frac{f_s}{f_d} =$ 0.240 $\pm$ 0.004(stat) $\pm$ 0.010(sys) $\pm$ 0.017(th). This result is based on a new approach that provides a significant improvement of the world average.

description: We report on a new constraint on gravitylike short-range forces, in which the interaction charge is mass, obtained by measuring the angular distribution of 5 A neutrons scattering off atomic xenon gas. Around 10^7 scattering events were collected at the 40 m small angle neutron scattering beam line located at the HANARO research reactor of the Korean Atomic Energy Research Institute. The extracted coupling strengths of new forces in the Yukawa-type parametrization are g^2 = (0.2 \pm 6.8 \pm 2.0) \times 10^-15 GeV^2 and g^2 = (-5.3 \pm 9.0 + 2.7 -2.8) \times 10^-17 GeV^2 for interaction ranges of 0.1 and 1.0 nm, respectively. These strengths correspond to 95% confidence level limits of g^2 < (1.4 \pm 0.2) \times 10^-14 GeV^-2 and g^2 < (1.3 \pm 0.2) \times 10^-16 GeV^-2, improving the current limits for interaction ranges between 4 and 0.04 nm by a factor of up to 10.

description: Epidemic processes are common out-of-equilibrium phenomena of broad interdisciplinary interest. Recently, dynamic message-passing (DMP) has been proposed as an efficient algorithm for simulating epidemic models on networks, and in particular for estimating the probability that a given node will become infectious at a particular time. To date, DMP has been applied exclusively to models with one-way state changes, as opposed to models like SIS (susceptible-infectious-susceptible) and SIRS (susceptible-infectious-recovered-susceptible) where nodes can return to previously inhabited states. Because many real-world epidemics can exhibit such recurrent dynamics, we propose a DMP algorithm for complex, recurrent epidemic models on networks. Our approach takes correlations between neighboring nodes into account while preventing causal signals from backtracking to their immediate source, and thus avoids "echo chamber effects" where a pair of adjacent nodes each amplify the probability that the other is infectious. We demonstrate that this approach well approximates results obtained from Monte Carlo simulation and that its accuracy is often superior to the pair approximation (which also takes second-order correlations into account). Moreover, our approach is more computationally efficient than the pair approximation, especially for complex epidemic models: the number of variables in our DMP approach grows as $2mk$ where $m$ is the number of edges and $k$ is the number of states, as opposed to $mk^2$ for the pair approximation. We suspect that the resulting reduction in computational effort, as well as the conceptual simplicity of DMP, will make it a useful tool in epidemic modeling, especially for inference tasks where there is a large parameter space to explore.

description: This paper considers probabilistic estimation of a low-rank matrix from non-linear element-wise measurements of its elements. We derive the corresponding approximate message passing (AMP) algorithm and its state evolution. Relying on non-rigorous but standard assumptions motivated by statistical physics, we characterize the minimum mean squared error (MMSE) achievable information theoretically and with the AMP algorithm. Unlike in related problems of linear estimation, in the present setting the MMSE depends on the output channel only trough a single parameter - its Fisher information. We illustrate this striking finding by analysis of submatrix localization, and of detection of communities hidden in a dense stochastic block model. For this example we locate the computational and statistical boundaries that are not equal for rank larger than four.

description: Warped models with the Higgs confined to the weak brane and the gauge and matter fields accessing the $AdS_5$ bulk provide viable setting to address the gauge hierarchy problem. Brane kinetic terms for the bulk fields are known to ease some of the tensions of these models with precision electroweak observables and flavor constraints. We study the loop-driven Higgs coupling to the gluons that are relevant to the Higgs program at LHC, in this scenario. We demonstrate a partial cancellation in the contribution of the fermionic Kaluza-Klein (KK) towers within such framework relatively independent of the 5D parameters. The entire dependence of this coupling on the new physics arises from the mixing between the Standard Model states and the KK excitations. We find that the present precision in measurement of these couplings can lead to a constraint on the KK scale up to 1.2 TeV at $95\%$ confidence level.

description: Il saggio, partendo dalla "lunga fedeltà" a Dante di Gramsci, prende in esame il dantesco "modello di intellettuale" che Gramsci fa suo. Quel modello, contrappposto a quello di Petrarca, si basa sul rapporto dell'intellettuale con la storia, la politica e con il popolo-nazione. Gramsci spinge più avanti tale modello, estendendolo al lavoro, in cui vede un'attività intellettuale di tutti gli uomini. La posizone gramsciana risale direttamente a De Sanctis, attraverso la mediazione di Umberto Cosmo, che fu suo professore.

As it turns out, among all sets of a given measure, the simplex or its complement (i.e. the ball in the $\ell_1$-metric or its complement) has the smallest boundary measure. The proof is based on a symmetrisation (along the sections of equal $\ell_1$-distance from the origin).

description: We study the role of quantum statistics in the performance of Otto cycles. First, we show analytically that the work distributions for bosonic and fermionic working fluids are identical for cycles driven by harmonic trapping potentials. Subsequently, in the case of non-harmonic potentials, we find that the interplay between different energy level spacings and particle statistics strongly affects the performances of the engine cycle. To demonstrate this, we examine three trapping potentials which induce different (single particle) energy level spacings: monotonically decreasing with the level number, monotonically increasing, and the case in which the level spacing does not vary monotonically.

description: We use astrophysical and atomic clock tests of the stability of the fine-structure constant $α$, together with Type Ia supernova and Hubble parameter data, to constrain the simplest class of dynamical dark energy models where the same degree of freedom is assumed to provide both the dark energy and (through a dimensionless coupling, $ζ$, to the electromagnetic sector) the $α$ variation. We show how current data tightly constrains a combination of $ζ$ and the dark energy equation of state $w_0$. At the $95\%$ confidence level and marginalizing over $w_0$ we find $|ζ|<5\times10^{-6}$, with the atomic clock tests dominating the constraints. The forthcoming generation of high-resolution ultra-stable spectrographs will enable significantly tighter constraints.

Based on the HEPfit package, our study updates the traditional fit of electroweak precision observables and extends it to include Higgs-boson measurements. As a result we obtain constraints on new physics corrections to both electroweak observables and Higgs-boson couplings. We present the projected accuracy of the fit taking into account the expected sensitivities at future colliders.

description: During the last 70 years, the quantum theory of angular momentum has been successfully applied to describing the properties of nuclei, atoms, and molecules, their interactions with each other as well as with external fields. Due to the properties of quantum rotations, the angular momentum algebra can be of tremendous complexity even for a few interacting particles, such as valence electrons of an atom, not to mention larger many-particle systems. In this work, we study an example of the latter: a rotating quantum impurity coupled to a many-body bosonic bath. In the regime of strong impurity-bath couplings the problem involves addition of an infinite number of angular momenta which renders it intractable using currently available techniques. Here, we introduce a novel canonical transformation which allows to eliminate the complex angular momentum algebra from such a class of many-body problems. In addition, the transformation exposes the problem's constants of motion, and renders it solvable exactly in the limit of a slowly-rotating impurity. We exemplify the technique by showing that there exists a critical rotational speed at which the impurity suddenly acquires one quantum of angular momentum from the many-particle bath. Such an instability is accompanied by the deformation of the phonon density in the frame rotating along with the impurity.

Free-Energy Functional Method for Inverse Problem of Self Assembly
Creators: name: Torikai, Masashi
Publisher: name: arXiv
Year: 2015
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: A new theoretical approach is described for the inverse self-assembly problem, i.e., the reconstruction of the interparticle interaction from a given structure. This theory is based on the variational principle for the functional that is constructed from a free energy functional in combination with Percus's approach [J. Percus, Phys. Rev. Lett. vol.8, 462 (1962)]. In this theory, the interparticle interaction potential for the given structure is obtained as the function that maximizes the functional. As test cases, the interparticle potentials for two-dimensional crystals, such as square, honeycomb, and kagome lattices, are predicted by this theory. The formation of each target lattice from an initial random particle configuration in Monte Carlo simulations with the predicted interparticle interaction indicates that the theory is successfully applied to the test cases.

description: When a particle is driven with an ac force over an asymmetric potential, it can undergo a ratchet effect that produces a net dc motion of the particle. Ratchet effects have been observed in numerous systems such as superconducting vortices on asymmetric pinning substrates. Skyrmions, stable topological spin textures with particle-like properties, have many similarities to vortices but their behavior is strongly influenced by non-disspative effects arising from a Magnus term in their equation of motion. We show using numerical simulations that pronounced ratchet effects can occur for ac driven skyrmions moving over asymmetric quasi-one-dimensional substrates. We find a new type of ratchet effect called a Magnus-induced transverse ratchet that arises when the ac driving force is applied perpendicular rather than parallel to the asymmetry direction of the substrate. This transverse ratchet effect only occurs when the Magnus term is finite, and the threshold ac amplitude needed to induce it decreases as the Magnus term becomes more prominent. Ratcheting skyrmions follow ordered orbits in which the net displacement parallel to the substrate asymmetry direction is quantized. Skyrmion ratchets represent a new ac current-based method for controlling skyrmion positions and motion for spintronic applications.

description: Decoherence of a central spin coupled to an interacting spin bath via inhomogeneous Heisenberg coupling is studied by two different approaches, namely an exact equations of motion (EOMs) method and a Chebyshev expansion technique (CET). By assuming a wheel topology of the bath spins with uniform nearest-neighbor $XX$-type intrabath coupling, we examine the central spin dynamics with the bath prepared in two different types of bath initial conditions. For fully polarized baths in strong magnetic fields, the polarization dynamics of the central spin exhibits a collapse-revival behavior in the intermediate-time regime. Under an antiferromagnetic bath initial condition, the two methods give excellently consistent central spin decoherence dynamics for finite-size baths of $N\leq14$ bath spins. The decoherence factor is found to drop off abruptly on a short time scale and approach a finite plateau value which depends on the intrabath coupling strength non-monotonically. In the ultrastrong intrabath coupling regime, the plateau values show an oscillatory behavior depending on whether $N/2$ is even or odd. The observed results are interpreted qualitatively within the framework of the EOM and perturbation analysis. The effects of anisotropic spin-bath coupling and inhomogeneous intrabath bath couplings are briefly discussed. Possible experimental realization of the model in a modified quantum corral setup is suggested.

Subjects: subject: Differential Geometry (math.DG)

description: The author proved that if the circle acts symplectically on a compact, connected symplectic manifold $M$ with three fixed points, then $M$ is equivariantly symplectomorphic to some standard action on $\mathbb{CP}^2$. In this paper, we extend the result to a circle action on an almost complex manifold; if the circle acts on a compact, connected almost complex manifold $M$ with exactly three fixed points, then $\dim M=4$. Moreover, we deal with the cases of one fixed point and two fixed points.

description: Single-layer FeSe film on SrTiO3(001) was recently found to be the champion of interfacial superconducting systems, with a much enhanced superconductivity than the bulk iron-based superconductors. Its superconducting mechanism is of great interest. Although the film has a simple Fermi surface topology, its pairing symmetry is unsettled. Here by using low-temperature scanning tunneling microscopy (STM), we systematically investigated the superconductivity of single-layer FeSe/SrTiO3(001) films. We observed fully gapped tunneling spectrum and magnetic vortex lattice in the film. Quasi-particle interference (QPI) patterns reveal scatterings between and within the electron pockets, and put constraints on possible pairing symmetries. By introducing impurity atoms onto the sample, we show that the magnetic impurities (Cr, Mn) can locally suppress the superconductivity but the non-magnetic impurities (Zn, Ag and K) cannot. Our results indicate that single-layer FeSe/SrTiO3 has a plain s-wave paring symmetry whose order parameter has the same phase on all Fermi surface sections.

title:  Il pensiero politico di Dante Alighieri nell’opera di Benedetto Croce
Creators: name: Cingari  ,  Salvatore
Publisher: name: Roma TrE-Press
Year: 2022

description: Il saggio ricostruisce il giudizio di Benedetto Croce sul pensiero politico di Dante Alighieri soffermandosi sul dapprima sul tendenziale silenzio di Croce, interrotto dal riferimento al saggio su Dante del 1921 al cui centro è la distinzione di poesia e non poesia e non il contenuto storico-politico della Commedia e delle altre opere. La sottovalutazione crociana della riflessione politica di Dante viene inoltre contestualizzata nel quadro delle polemiche del filosofo con la “dantomania”, l’eruditismo positivista, con il nazionalismo, con le interpretazioni decadentistiche, e con la lettura di Giovanni Gentile. Il saggio affrontato poi l’unico testo in cui Croce tratta miratamente il pensiero politico dantesco, una voce per l’Enciclopedia of social science (New York, 1930), in egli riconosceva la valorizzazione dantesca della sovranità statale, indicandone però il carattere austero e intransigente come modello di ispirazione morale per resistere al conformismo degli anni del regime.

A Boxing Inequality for the Fractional Perimeter

description: We prove the Boxing inequality: $$\mathcal{H}^{d-α}_\infty(U) \leq Cα(1-α)\int_U \int_{\mathbb{R}^{d} \setminus U} \frac{\mathrm{d}y \, \mathrm{d}z}{|y-z|^{α+d}},$$ for every $α\in (0,1)$ and every bounded open subset $U \subset \mathbb{R}^d$, where $\mathcal{H}^{d-α}_\infty(U)$ is the Hausdorff content of $U$ of dimension $d -α$ and the constant $C > 0$ depends only on $d$. We then show how this estimate implies a trace inequality in the fractional Sobolev space $W^{α, 1}(\mathbb{R}^d)$ that includes Sobolev's $L^{\frac{d}{d - α}}$ embedding, its Lorentz-space improvement, and Hardy's inequality. All these estimates are thus obtained with the appropriate asymptotics as $α$ tends to $0$ and $1$, recovering in particular the classical inequalities of first order. Their counterparts in the full range $α\in (0, d)$ are also investigated.

description: Maximizing the amount of work harvested from an environment is important for a wide variety of biological and technological processes, from energy-harvesting processes such as photosynthesisto energy storage systems such as fuels and batteries. Here we consider the maximization of free energy -- and by extension, the maximum extractable work -- that can be gained by a classical or quantum system that undergoes driving by its environment. We consider how the free energy gain depends on the initial state of the system, while also accounting for the cost of preparing the system. We provide simple necessary and sufficient conditions for increasing the gain of free energy by varying the initial state. We also derive simple formulae that relate the free energy gained using the optimal initial state rather than another suboptimal initial state. Finally, we demonstrate that the problem of finding the optimal initial state may have two distinct regimes, one easy and one difficult, depending on the temperatures used for preparation and work extraction. We illustrate our results on a simple model of an information engine.

title: Πειραματικός χαρακτηρισμός αντίστασης πετρωμάτων στην διάτρηση με την μέθοδο πτώσης βάρους
Creators: name: Ηλιοπουλος Φοιβος
Publisher: name: Technical University of Crete
Year: 2023

description: Αντικείμενο της διπλωματικής εργασίας είναι η μελέτη αντίστασης των πετρωμάτων με τη μέθοδο πτώση βάρους. Για την εκτέλεση των πειραμάτων χρησιμοποιήθηκε μη εμπορική μηχανή δοκιμής κάμψεως με δυνατότητα τροποποίησης για την εκτέλεση του πειράματος σημειακής φόρτισης με κοπτικό άκρο σημειακής προσβολής. Το επίκεντρο αυτής της εργασίας είναι η προσομοίωση των μηχανημάτων σημειακής κοπής (Road Header) και της κρουστή-περιστροφικής διάτρησης που χρησιμοποιούνται στη διάτρηση-ανατίναξη. Με την σημειακή φόρτιση παρατηρούμε τη μηχανική συμπεριφορά που θα παρουσιάσει ένα υλικό όταν υποστεί κρουστική φόρτιση που προκαλεί την άμεση παραμόρφωση, θραύση ή πλήρη ρήξη του δείγματος. Tο επιστημονικό πρόβλημα που η διπλωματική εργασία καλείται να επιλύσει είναι η επεξεργασία των αποτελεσμάτων για την καλύτερη απόδοση των μηχανημάτων σημειακής κοπής και της κρουστή-περιστροφικής διάτρησης απέναντι στο μέτωπο. Το επιλεγμένο θέμα αποτελεί πρόβλημα που απαιτεί επιστημονική λύση διότι για να έχουμε την καλύτερη απόδοση των μηχανημάτων πρέπει να μελετηθούν πολύ παράγοντες πριν ξεκινήσει μια διάνοιξη υπόγειων ανοιγμάτων, π.χ. Το σχήμα του εμβόλου, τη μηχανική συμπεριφορά του πετρώματος, τη γεωμετρία κοπής κ.α. Το υπό εξέταση πρόβλημα επιλύθηκε κάνοντας πειράματα σε δοκίμια διάφορων πετρωμάτων στη μηχανή σημειακής φόρτισης. Τα πετρώματα ήταν ασβεστόλιθοι από την περιοχή του Ακρωτηρίου, ψαμμίτες (σκληροί, μαλακοί) από την περιοχή του Καλαθά και σκυρόδεμα. Μελετήσαμε την μηχανική συμπεριφορά των πετρωμάτων κάνοντας μονοάξονικη θλίψη και υπολογίσαμε με διάφορες μεθόδους τον όγκο του κρατήρα, ανάλογα με το ύψος και το βάρος του εμβόλου, η πρώτη μέθοδος ήταν με το όργανο παχύμετρο και η δεύτερη μέθοδος ήταν με την χρήση της ψηφιοποίησης, άλλη μια μέθοδο την οποία χρησιμοποιήσαμε ήταν με την δοκιμή της πούδρας.
