description: Weak value amplification and other postselection-based metrological protocols can enhance precision while estimating small parameters, outperforming postselection-free protocols. In general, these enhancements are largely constrained because the protocols yielding higher precision are rarely obtained due to a lower probability of successful postselection. It is shown that this precision can further be improved with the help of quantum resources like entanglement and negativity in the quasiprobability distribution. However, these quantum advantages in attaining considerable success probability with large precision are bounded irrespective of any accessible quantum resources. Here we derive a bound of these advantages in postselected metrology, establishing a connection with weak value optimization where the latter can be understood in terms of geometric phase. We introduce a scheme that saturates the bound, yielding anomalously large precision. Usually, negative quasiprobabilities are considered essential in enabling postselection to increase precision beyond standard optimized values. In contrast, we prove that these advantages can indeed be achieved with positive quasiprobability distribution. We also provide an optimal metrological scheme using three level non-degenerate quantum system.

description: In this note we study the induced $p$-norm of circulant matrices $A(n,\pm a, b)$, acting as operators on the Euclidean space $\mathbb{R}^n$. For circulant matrices whose entries are nonnegative real numbers, in particular for $A(n,a,b)$, we provide an explicit formula for the $p$-norm, $1 \leq p \leq \infty$. The calculation for $A(n,-a,b)$ is more complex. The 2-norm is precisely determined. As for the other values of $p$, two different categories of upper and lower bounds are obtained. These bounds are optimal at the end points (i.e. $p=1$ and $p = \infty$) as well as at $p=2$.

Pair Creation of Massless Fermions in Electric Flux Tube

description: Using chiral anomaly, we discuss the pair creation of massless fermions in an electric flux tube $\vec{E}$ under homogeneous magnetic field $\vec{B}$ parallel to $\vec{E}$. The tube is axial symmetric and infinitely long in longitudinal direction. In the limit $B\gg E$, we can analytically obtain the spatial and temporal behaviors of the electric field and azimuthal magnetic field generated by the produced fermions. We find that the life time $t_c$ of the electric field is shorter as the width of the tube is narrower. Applying it to the glasma in high-energy heavy-ion collisions, we find that color electric field decays fast such as $t_c\simeq Q_s^{-1}$ with saturation momentum $Q_s$.

description: In this paper, we study the spectral efficiency (SE) and energy efficiency (EE) of asymmetrically clipped optical orthogonal frequency division multiplexing (ACO-OFDM) for visible light communication (VLC). Firstly, we derive the achiev-able rates for Gaussian distributions inputs and practical finite-alphabet inputs. Then, we investigate the SE maximization problems subject to both the total transmit power constraint and the average optical power constraint with the above two inputs, respectively. By exploiting the relationship between the mutual information and the minimum mean-squared error, an optimal power allocation scheme is proposed to maximize the SE with finite-alphabet inputs. To reduce the computational complexity of the power allocation scheme, we derive a closed-form lower bound of the SE. Also, considering the quality of service, we further tackle the non-convex EE maximization problems of ACO-OFDM with the two inputs, respectively. The problems are solved by the proposed Dinkelbach-type iterative algorithm. In each iteration, the interior point algorithm is applied to obtain the optimal power allocation.The performance of the proposed power allocation schemes for the SE and EE maximization are validated through numerical analysis.

Random Dirac operators with time-reversal symmetry

description: Quasi-one-dimensional stochastic Dirac operators with an odd number of channels, time reversal symmetry but otherwise efficiently coupled randomness are shown to have one conducting channel and absolutely continuous spectrum of multiplicity two. This follows by adapting the criteria of Guivarch-Raugi and Goldsheid-Margulis to the analysis of random products of matrices in the group SO$^*(2L)$, and then a version of Kotani theory for these operators. Absence of singular spectrum can be shown by adapting an argument of Jaksic-Last if the potential contains random Dirac peaks with absolutely continuous distribution.

Measurement of Cosmic Ray Spectrum and Anisotropy with the ARGO-YBJ
  experiment

Publisher: name: INFN Open Access Repository
Year: 2013

description: The combined measurement of the cosmic ray (CR) energy spectrum and
anisotropy in their arrival direction distribution needs the knowledge of the
elemental composition of the radiation to discriminate between different origin
and propagation models. Important information on the CR mass composition can be
obtained studying the EAS muon content through the measurement of the CR rate
at different zenith angles.
  In this paper we report on the observation of the anisotropy of galactic CRs
at different angular scales with the ARGO-YBJ experiment. We report also on the
study of the primary CR rate for different zenith angles. The light component
(p+He) has been selected and its energy spectrum measured in the energy range
(5 - 200) TeV for quasi-vertical events. With this analysis for the first time
a ground-based measurement of the CR spectrum overlaps data obtained with
direct methods for more than one energy decade, thus providing a solid
anchorage to the CR spectrum measurements carried out by EAS arrays in the knee
region.
  Finally, a preliminary study of the non-attenuated shower component at a
zenith angle $\theta >$ 70$^{\circ}$ (through the observation of the so-called
horizantal air showers) is presented.

description: We perform a consistent modeling of cosmic ray electrons, positrons and of
the radio emission of the Galaxy. For the time we reproduce all relevant data
sets between 1 GeV and 1 TeV including the recent AMS-02 positron fraction
results.
  We show that below few GeV cosmic ray and radio data require that electron
primary spectrum to be drastically suppressed and the propagated spectrum be
dominated by secondary particles. Above 10 GeV an electron + positron
extra-component with a hard spectrum is required. The positron spectrum
measured below few GeV is consistently reproduced only within low
reacceleration models. We also constrain the scale-height of the cosmic-ray
distribution showing that a thin halo ($z_t \lsim 2 \kpc$) is excluded.

description: On the 17th of August 2017, the thriving discovery of gravitational waves event GW170817 and its optical counterpart GRB170817A, owing to coalescing of two neutron starts divulged a very small amount of difference around ${\cal O}(10^{-16})$ between traveling speed of light and the velocity of gravitational waves ($C_{T}$). This small deviation can be used as a strong constraint on modified gravity models. We concentrate on the Higher-Order expansion of Mimetic Gravity (HOMimG) model to specify the parametric space of three parameters of our model ($a$, $b$, and $c$ ) utilizing the observational constraint from GW170817-GRB170817A on $C_{T}$, besides two theoretical constraints on $C_{T}^{2}$ and $C_{s}^{2}$ due to assurance of the stability of the model and subluminal promulgation of the scalar and tensor perturbations. Thereafter, we increase the accuracy of the parametric space with the aid of imposing further limitation of $γ$ parameter (related to the age of the Universe). In pursuance of determining the other parameter of the model ($λ$), the potential of the model is specified, and another observational bound related to the Equation of State (EoS) parameter of dark energy is taken into account. In consequence, we attain a viable HOMimG model confined to numbers of observational and theoretical constraints. At the end, regarding the concluded numerical ranges for the model parameters, and cogitating two different potential (quadratic and quartic potentials) to specify $λ$ parameter, we illustrate that the values of the model parameters are independent of the form of potential.

description: Wireless mobile grids are one of the emerging grid types, which help to pool the resources of several willing and cooperative mobile devices to resolve a computationally intensive task. The mobile grids exhibit stronger challenges like mobility management of devices, providing transparent access to grid resources, task management and handling of limited resources so that resources are shared efficiently. Task execution on these devices should not be affected by their mobility. The proposed work presents performance evaluation of wireless mobile grid using normal walk mobility model. The normal walk model represents daily motion of users and the direction of motion is mostly symmetric in a real life environment, thus it is effective in location updating of a mobile station and in turn helps task distribution among these available mobile stations. Some of the performance parameters such as Task Execution Time, task failure rate, communication overhead on Brokering Server and Monitoring Cost are discussed.

description: Visible-infrared cross-modality person re-identification is a challenging ReID task, which aims to retrieve and match the same identity's images between the heterogeneous visible and infrared modalities. Thus, the core of this task is to bridge the huge gap between these two modalities. The existing convolutional neural network-based methods mainly face the problem of insufficient perception of modalities' information, and can not learn good discriminative modality-invariant embeddings for identities, which limits their performance. To solve these problems, we propose a cross-modality transformer-based method (CMTR) for the visible-infrared person re-identification task, which can explicitly mine the information of each modality and generate better discriminative features based on it. Specifically, to capture modalities' characteristics, we design the novel modality embeddings, which are fused with token embeddings to encode modalities' information. Furthermore, to enhance representation of modality embeddings and adjust matching embeddings' distribution, we propose a modality-aware enhancement loss based on the learned modalities' information, reducing intra-class distance and enlarging inter-class distance. To our knowledge, this is the first work of applying transformer network to the cross-modality re-identification task. We implement extensive experiments on the public SYSU-MM01 and RegDB datasets, and our proposed CMTR model's performance significantly surpasses existing outstanding CNN-based methods.

description: Using recent experimental data, we analyze the electromagnetic transition from the nucleon to the P11(1440) resonance. From the resulting empirical transition form factors, we map out the quark transverse charge densities which induce the N to P11(1440) transition. It is found that the transition from the proton to its first radially excited state is dominated by up quarks in a central region of around 0.5 fm and by down quarks in an outer band which extends up to about 1 fm.

A PNJL Model for Adjoint Fermions with Periodic Boundary Conditions

description: Recent work on QCD-like theories has shown that the addition of adjoint fermions obeying periodic boundary conditions to gauge theories on $R^{3}\times S^{1}$ can lead to a restoration of center symmetry and confinement for sufficiently small circumference $L$ of $S^{1}$. At small $L$, perturbation theory may be used reliably to compute the effective potential for the Polyakov loop $P$ in the compact direction. Periodic adjoint fermions act in opposition to the gauge fields, which by themselves would lead to a deconfined phase at small $L$. In order for the fermionic effects to dominate gauge field effects in the effective potential, the fermion mass must be sufficiently small. This indicates that chiral symmetry breaking effects are potentially important. We develop a Polyakov-Nambu-Jona Lasinio (PNJL) model which combines the known perturbative behavior of adjoint QCD models at small $L$ with chiral symmetry breaking effects to produce an effective potential for the Polyakov loop $P$ and the chiral order parameter $\barψψ$. A rich phase structure emerges from the effective potential. Our results are consistent with the recent lattice simulations of Cossu and D'Elia, which found no evidence for a direct connection between the small-$L$ and large-$L$ confining regions. Nevertheless, the two confined regions are connected indirectly if an extended field theory model with an irrelevant four-fermion interaction is considered. Thus the small-$L$ and large-$L$ regions are part of a single confined phase.

Data inversion for over-resolved spectral imaging in astronomy

description: We present an original method for reconstructing a three-dimensional object having two spatial dimensions and one spectral dimension from data provided by the infrared slit spectrograph on board the Spitzer Space Telescope. During acquisition, the light flux is deformed by a complex process comprising four main elements (the telescope aperture, the slit, the diffraction grating and optical distortion) before it reaches the two-dimensional sensor. The originality of this work lies in the physical modelling, in integral form, of this process of data formation in continuous variables. The inversion is lso approached with continuous variables in a semi-parametric format decomposing the object into a family of Gaussian functions. The estimate is built in a deterministic regularization framework as the minimizer of a quadratic criterion. These specificities give our method the power to over-resolve. Its performance is illustrated using real and simulated data. We also present a study of the resolution showing a 1.5-fold improvement relative to conventional methods.

Through precision straits to next standard model heights
Creators: name: David, André
name: Passarino, Giampiero
Publisher: name: INFN Open Access Repository
Year: 2015

description: After the LHC Run 1, the standard model (SM) of particle physics has been
completed. Yet, despite its successes, the SM has shortcomings vis-\`{a}-vis
cosmological and other observations. At the same time, while the LHC restarts
for Run 2 at 13 TeV, there is presently a lack of direct evidence for new
physics phenomena at the accelerator energy frontier. From this state of
affairs arises the need for a consistent theoretical framework in which
deviations from the SM predictions can be calculated and compared to precision
measurements. Such a framework should be able to comprehensively make use of
all measurements in all sectors of particle physics, including LHC Higgs
measurements, past electroweak precision data, electric dipole moment, $g-2$,
penguins and flavor physics, neutrino scattering, deep inelastic scattering,
low-energy $e^{+}e^{-}$ scattering, mass measurements, and any search for
physics beyond the SM. By simultaneously describing all existing measurements,
this framework then becomes an intermediate step, pointing us toward the next
SM, and hopefully revealing the underlying symmetries. We review the role that
the standard model effective field theory (SMEFT) could play in this context,
as a consistent, complete, and calculable generalization of the SM in the
absence of light new physics. We discuss the relationship of the SMEFT with the
existing kappa-framework for Higgs boson couplings characterization and the use
of pseudo-observables, that insulate experimental results from refinements due
to ever-improving calculations. The LHC context, as well as that of previous
and future accelerators and experiments, is also addressed.

Temperature-dependent striped antiferromagnetism of LaFeAsO in a Green's function approach

description: We use a Green's function method to study the temperature-dependent average moment and magnetic phase-transition temperature of the striped antiferromagnetism of LaFeAsO, and other similar compounds, as the parents of FeAs-based superconductors. We consider the nearest and the next-nearest couplings in the FeAs layer, and the nearest coupling for inter-layer spin interaction. The dependence of the transition temperature TN and the zero-temperature average spin on the interaction constants is investigated. We obtain an analytical expression for TN and determine our temperature-dependent average spin from zero temperature to TN in terms of unified self-consistent equations. For LaFeAsO, we obtain a reasonable estimation of the coupling interactions with the experimental transition temperature TN = 138 K. Our results also show that a non-zero antiferromagnetic (AFM) inter-layer coupling is essential for the existence of a non-zero TN, and the many-body AFM fluctuations reduce substantially the low-temperature magnetic moment per Fe towards the experimental value. Our Green's function approach can be used for other FeAs-based parent compounds and these results should be useful to understand the physical properties of FeAs-based superconductors.

description: The total photoproduction cross section at ultra-high energies is obtained
using a model based on QCD minijets and soft-gluon resummation and the ansatz
that infrared gluons limit the rise of total cross sections. This cross section
is introduced into the Monte Carlo system AIRES to simulate extended
air-showers initiated by cosmic ray photons. The impact of the new
photoproduction cross section on common shower observables, especially those
related to muon production, is compared with previous results.

description: Physical unclonable functions(PUFs) provide a unique fingerprint to a physical entity by exploiting the inherent physical randomness. Gao et al. discussed the vulnerability of most current-day PUFs to sophisticated machine learning-based attacks. We address this problem by integrating classical PUFs and existing quantum communication technology. Specifically, this paper proposes a generic design of provably secure PUFs, called hybrid locked PUFs(HLPUFs), providing a practical solution for securing classical PUFs. An HLPUF uses a classical PUF(CPUF), and encodes the output into non-orthogonal quantum states to hide the outcomes of the underlying CPUF from any adversary. Here we introduce a quantum lock to protect the HLPUFs from any general adversaries. The indistinguishability property of the non-orthogonal quantum states, together with the quantum lockdown technique prevents the adversary from accessing the outcome of the CPUFs. Moreover, we show that by exploiting non-classical properties of quantum states, the HLPUF allows the server to reuse the challenge-response pairs for further client authentication. This result provides an efficient solution for running PUF-based client authentication for an extended period while maintaining a small-sized challenge-response pairs database on the server side. Later, we support our theoretical contributions by instantiating the HLPUFs design using accessible real-world CPUFs. We use the optimal classical machine-learning attacks to forge both the CPUFs and HLPUFs, and we certify the security gap in our numerical simulation for construction which is ready for implementation.

A relativistic signature in large-scale structure: Scale-dependent bias

description: In General Relativity, the constraint equation relating metric and density
perturbations is inherently nonlinear, leading to an effective non-Gaussianity
in the density field on large scales -- even if the primordial metric
perturbation is Gaussian. This imprints a relativistic signature in large-scale
structure which is potentially observable, for example via a scale-dependent
galaxy bias. The effect has been derived and then confirmed by independent
calculations, using second-order perturbation theory. Recently, the physical
reality of this relativistic effect has been disputed. The counter-argument is
based on the claim that a very long wavelength curvature perturbation can be
removed by a coordinate transformation. We argue that while this is true
locally, the large-scale curvature cannot be removed by local coordinate
transformations. The transformation itself contains the long-wavelength modes
and thus includes the correlation. We show how the separate universe approach
can be used to understand this correlation, confirming the results of
perturbation theory.

description: We describe and compare several post-correlation radio frequency interference classification methods. As data sizes of observations grow with new and improved telescopes, the need for completely automated, robust methods for radio frequency interference mitigation is pressing. We investigated several classification methods and find that, for the data sets we used, the most accurate among them is the SumThreshold method. This is a new method formed from a combination of existing techniques, including a new way of thresholding. This iterative method estimates the astronomical signal by carrying out a surface fit in the time-frequency plane. With a theoretical accuracy of 95% recognition and an approximately 0.1% false probability rate in simple simulated cases, the method is in practice as good as the human eye in finding RFI. In addition it is fast, robust, does not need a data model before it can be executed and works in almost all configurations with its default parameters. The method has been compared using simulated data with several other mitigation techniques, including one based upon the singular value decomposition of the time-frequency matrix, and has shown better results than the rest.
