The dynamical role of initial correlation in the exactly solvable dephasing model
Creators: name: Gao, Yang

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We investigate the effects of the initial correlation on the dynamics of open system in the exactly solvable pure dephasing model. We show that the role of the initial correlation come into play through a phase function and a weight factor, which would perform oscillations during time evolution, and find that the decoherence of a qubit coupled to a boson bath is more enhanced with respect to a spin bath in the short time. We also demonstrate that the trace distance between two states of a qubit can increase above its initial value, and that the initial correlation can provide another resource for the damply oscillation and revival of the entanglement of two qubits. We finally investigate the dependence of the crossover of decoherence from the dynamical enhancement to suppression under the bang-bang pulse control on the initial correlation and the statistics of the bath constituents.

description: For every spatial embedding of each graph in the Petersen family, it is known that the sum of the linking numbers over all of the constituent 2-component links is congruent to 1 modulo 2. In this paper, we give an integral lift of this formula in terms of the square of the linking number and the second coefficient of the Conway polynomial.

description: We analyze the behavior of a network of quantum oscillators coupled with a number of external environments. We show that the dynamics is such that the quantum state of the network always obeys a local master equation with a simple analytical solution. We use this to study the emergence of thermodynamical laws in the stationary regime, achieved for sufficiently long times if the environments are dissipative. We show that the validity of the second law implies the impossibility of building a quantum refrigerator without moving parts (therefore, a quantum absorption refrigerators requires non-linearity as an crucial ingredient, as recently proposed by Kosloff and others cite{Kosloff1,Kosloff2}). We also show that the third law imposes strong constraints on the low frequency behavior of the environmental spectral densities.

description: The bcβγ-system W of rank 3 has an action of the affine vertex algebra V_0(sl_2), and the commutant vertex algebra C =Com(V_0(sl_2), W) contains copies of V_{-3/2}(sl_2) and Odake's algebra O. Odake's algebra is an extension of the N=2 superconformal algebra with c=9, and is generated by eight fields which close nonlinearly under operator product expansions. Our main result is that V_{-3/2}(sl_2) and O form a Howe pair (i.e., a pair of mutual commutants) inside C. More generally, any finite-dimensional representation of a Lie algebra g gives rise to a similar Howe pair, and this example corresponds to the adjoint representation of sl_2.

description: Layered superconductors have provided some interesting fields in condensed matter physics owing to the low dimensionality of their electronic states. For example, the high-Tc (high transition temperature) cuprates and the Fe-based superconductors possess a layered crystal structure composed of a stacking of spacer (blocking) layers and conduction (superconducting) layers, CuO2 planes or Fe-Anion layers. The spacer layers provide carriers to the conduction layers and induce exotic superconductivity. Recently, we have reported superconductivity in the novel BiS2-based layered compound Bi4O4S3. It was found that superconductivity of Bi4O4S3 originates from the BiS2 layers. The crystal structure is composed of a stacking of BiS2 superconducting layers and the spacer layers, which resembles those of high-Tc cuprate and the Fe-based superconductors. Here we report a discovery of a new type of BiS2-based layered superconductor LaO1-xFxBiS2, with a Tc as high as 10.6 K.

description: In the present study, Mentha plant ash was modified by Na and Al for the synthesis of adsorbent and applied for the removal of Fluoride from an aqueous solution. Mixture of acid washed Mentha plant ash (MPA) and NaOH (in the ratio 1:1.3) thermally treated at 600°C in a muffle furnace then treated with aqueous solution of sodium aluminate. The characterization of sodium aluminum modified ash (Na-Al-MA) powder was done such as SEM (Scanning Electron Microscopy), Particle Size Analysis (PSA), Fourier transformed spectroscopy (FTIR), Zeta Potential, XRD (X-ray Diffraction) analysis, and Brunauer–Emmett–Teller (BET) analysis. The removal of fluoride from an aqueous solution carried out with Na-Al-MA by batch adsorption process. The Na-Al-MA was found to be very effective as adsorbent. The maximum removal of fluoride was achieved ̴ 86% at neutral pH and at room temperature. It was investigated that Langmuir adsorption isotherm and pseudo-second-order kinetic was best fitted for fluoride adsorption. The fluoride adsorption on Na-Al-MA was an exothermic process. A possible mechanism including electrostatic attraction, hydrogen bonding, and metal-fluoride interaction for fluoride adsorption on Na-Al-MA have described in this study. Novelty statement: Utilization of Mentha plant ash for the development of adsorbent and its application in adsorptive removal of fluoride from aqueous solution is the novelty of this work. Adsorbent preparation may be the better way of waste biomass management.
Firing statistics of inhibitory neuron with delayed feedback. II. Non-Markovian behavior

description: The instantaneous state of a neural network consists of both the degree of excitation of each neuron the network is composed of and positions of impulses in communication lines between the neurons. In neurophysiological experiments, the neuronal firing moments are registered, but not the state of communication lines. But future spiking moments depend essentially on the past positions of impulses in the lines. This suggests, that the sequence of intervals between firing moments (inter-spike intervals, ISIs) in the network could be non-Markovian. In this paper, we address this question for a simplest possible neural "net", namely, a single inhibitory neuron with delayed feedback. The neuron receives excitatory input from the driving Poisson stream and inhibitory impulses from its own output through the feedback line. We obtain analytic expressions for conditional probability density P(t_{n+1}| t_n,...,t_1,t_0), which gives the probability to get an output ISI of duration t_{n+1} provided the previous (n+1) output ISIs had durations t_n,...,t_1,t_0. It is proven exactly, that P(t_{n+1}| t_n,...,t_1,t_0) does not reduce to P(t_{n+1}| t_n,...,t_1) for any n>=0. This means that the output ISIs stream cannot be represented as a Markov chain of any finite order.

description: Lowlands of Yaounde, Cameroon are facing soil pollution due to all type of organic and inorganic wastes, particularly heavy metal due to anthropogenic activities. Identifying macrophytes species able to develop on heavy metal polluted soils remains an essential step in the phytoremediation process which used living green plants. In this study, floristic surveys using the quadrat method were conducted in lowland areas surrounded by heavy metal pollution sources activities of Yaounde to identify macrophytes species with phytoremediation capacities. Inventories were conducted in 11 polluted lowlands and results were compared to control which is an unpolluted area. A total of 189 species belonging to 138 genera distributed in 63 families were identified on polluted sites. Macrophytes diversity was higher in each polluted site compared to the control. Poaceae, Asteraceae, Fabaceae, Malvaceae, and Solanaceae families showed a higher taxonomic richness on polluted sites (23, 20, 14, 12, and 12 taxa, respectively). Shannon diversity index of the lowlands polluted sites 2.69 was significantly higher than the control 2.3. Pielou equitability index in contaminated sites (0.459–0.847) was not significantly different from the control 0.747. Based on the abundance and relative frequency (≥10%), our results show that more than 10 macrophytes species existing in these lowlands areas could be tested in preliminary trials to investigate their phytoremediation/cleaning-up capacities on polluted soils in the tropical zone. This study presents original results for field surveys in lowland sites polluted in Yaounde-Cameroon. The screening of 11 polluted lowlands compared to a natural lowland (unpolluted), made it possible to identify species which may exhibit the best capacities to adapt to environmental changes and to develop in contaminated areas, in particular heavy metals. This work can be a preliminary study around the species growing in contaminated lowlands. Thus, this study can be reproduced in other regions, to compare the results obtained and identify potential plants for the lowlands remediation in Cameroon.

description: In this short letter we present the construction of a bi-stochastic kernel p for an arbitrary data set X that is derived from an asymmetric affinity function α. The affinity function α measures the similarity between points in X and some reference set Y. Unlike other methods that construct bi-stochastic kernels via some convergent iteration process or through solving an optimization problem, the construction presented here is quite simple. Furthermore, it can be viewed through the lens of out of sample extensions, making it useful for massive data sets.

Requirements of Situation Awareness

Decision Making

description: This deliverable is produced in the scope of WP3’s D3.7 “Requirements to Situation Awareness and SA Model v.2”. D3.7 describes methods for finding the necessary knowledge for first responders in order to achieve a level of situation awareness and to develop disaster emergencies. Situation Awareness (SA) is the accuracy with which people perceive, recognize and anticipate modifications in their environment that are relevant to achieving operational goals. Initially, in order to capture, develop, share and use organizational knowledge to finally enable SA, a Knowledge Management System is required. The Knowledge Management System requires components, both human and hardware, that must follow a variety of operational goals (time of response, time of deployment, rescue victims etc.).
 The goal of the deliverable, is the further extension of requirements to D3.1, the definition of the requirements of the Knowledge Management functionality in order to enable the situation awareness, a more efficient context-aware data sharing and presentation to the emergency responding actors, and subsequently more efficient decision-making support. The requirements to be collected should address different aspects of the S&R system functionality such as: knowledge models and information elements required to represent various types of resources used in S&R operations the support required for various types of decision making and decision points during S&R operations the requirements to the overall knowledge management infrastructure to support the achieving of situation awareness. These needs will support the risk awareness in decision-making, related to both victims as well as staff on the field.

description: Let $u$ be the solution to the following stochastic evolution equation (1) du(t,x)& = &A u(t,x) dt + B σ(u(t,x)) dL(t),\quad t>0; u(0,x) = x taking values in an Hilbert space $\HH$, where $L$ is a $\RR$ valued Lévy process, $A:H\to H$ an infinitesimal generator of a strongly continuous semigroup, $σ:H\to \RR$ bounded from below and Lipschitz continuous, and $B:\RR\to H$ a possible unbounded operator. A typical example of such an equation is a stochastic Partial differential equation with boundary Lévy noise. Let $\CP=(\CP_t)_{t\ge 0}$ %{\CP_t:0\le t0 u(0) = x is approximate controllable in time $T>0$, then under some additional conditions on $B$ and $A$, for any $x\in H$ the probability measure $\CP_T^\star δ_x$ is positive on open sets of $H$. Secondly, as an application, we investigate under which condition on %$\HH$ and on the Lévy process $L$ and on the operator $A$ and $B$ the solution of Equation [1] is asymptotically strong Feller, respective, has a unique invariant measure. We apply these results to the damped wave equation driven by Lévy boundary noise.

description: Let X be a smooth, connected, projective variety over an algebraically closed field of positive characteristic. In "Flat vector bundles and the fundamental group in non-zero characteristics" (Ann. Scuola Norm. Sup. Pisa Cl. Sci. (4) 2 (1975)), Gieseker conjectured that every stratified bundle (i.e. every O-coherent D-module) on X is trivial, if and only if the étale fundamental group of X is trivial. This was proven by Esnault-Mehta in "Simply connected projective manifolds in characteristic p> 0 have no nontrivial stratified bundles" (Invent. Math. 181 (2010)). Building on the classical situation over the complex numbers, we present and motivate a generalization of Gieseker's conjecture using the notion of regular singular stratified bundles developed in the author's thesis and arXiv:1210.5077. In the main part of this article we establish some important special cases of this generalization; most notably we prove that for not necessarily proper X, the vanishing of the tame fundamental group of X implies that there are no nontrivial regular singular stratified bundles with abelian monodromy.

description: Graph Laplacians and related nonlinear mappings into low dimensional spaces have been shown to be powerful tools for organizing high dimensional data. Here we consider a data set X in which the graph associated with it changes depending on some set of parameters. We analyze this type of data in terms of the diffusion distance and the corresponding diffusion map. As the data changes over the parameter space, the low dimensional embedding changes as well. We give a way to go between these embeddings, and furthermore, map them all into a common space, allowing one to track the evolution of X in its intrinsic geometry. A global diffusion distance is also defined, which gives a measure of the global behavior of the data over the parameter space. Approximation theorems in terms of randomly sampled data are presented, as are potential applications.

description: We introduce a monogamy inequality for quantum correlations, which implies that the sum of pairwise quantum correlations is upper limited by the amount of multipartite quantum correlations as measured by the global quantum discord. This monogamy bound holds either for pure or mixed quantum states provided that bipartite quantum discord does not increase under discard of subsystems. We illustrate the monogamy behavior for multipartite pure states with Schmidt decomposition as well as for W-GHZ mixed states. As a by-product, we apply the monogamy bound to investigate residual multipartite correlations.

description: We study the structure of topological phases and their boundaries in the Projected Entangled Pair States (PEPS) formalism. We show how topological order in a system can be identified from the structure of the PEPS transfer operator, and subsequently use these findings to analyze the structure of the boundary Hamiltonian, acting on the bond variables, which reflects the entanglement properties of the system. We find that in a topological phase, the boundary Hamiltonian consists of two parts: A universal non-local part which encodes the nature of the topological phase, and a non-universal part which is local and inherits the symmetries of the topological model, which helps to infer the structure of the boundary Hamiltonian and thus possibly of the physical edge modes.

Patients were recruited during the years 2017-2020 mainly from the outpatients of the Institute of Endocrinology in Prague. These patients are continuously monitored at the Institute, which gives us detailed long-term or even lifelong retrospective information on the status of their disease. Next generation sequencing performed on a MiSeq (Illumina) was used for haplotyping. In the three HLA genes (DRB1, DQA1 and DQB1), exon 2 was amplified, since this part of the HLA molecule determines its antigenic properties. Amplification of DNA sequences was performed using certified kits (CE 0197, CE IVD) of allele-specific pre-coated PCR strips PROTRANS S4 HLA-DRB1 * (cat. No. 34 04), PROTRANS S3 HLA-DQB1 * (cat.

description: We study the equilibrium correlations of a Bose gas in an elongated three-dimensional harmonic trap using a grand-canonical classical-field method. We focus in particular on the progressive transformation of the gas from the normal phase, through a phase-fluctuating quasicondensate regime to the so-called true-condensate regime, with decreasing temperature. Choosing realistic experimental parameters, we quantify the density fluctuations and phase coherence of the atomic field as functions of the system temperature. We identify the onset of Bose condensation through analysis of both the generalized Binder cumulant appropriate to the inhomogeneous system, and the suppression of the effective many-body T matrix that characterizes interactions between condensate atoms in the finite-temperature field. We find that the system undergoes a second-order transition to condensation near the critical temperature for an ideal Bose gas in the strongly anisotropic three-dimensional geometry, but remains in a strongly phase-fluctuating quasicondensate regime until significantly lower temperatures. We characterize the crossover from a quasicondensate to a true condensate by a qualitative change in the form of the non-local first-order coherence function of the field, and compare our results to those of previous works employing a density-phase Bogoliubov-de Gennes analysis.

description: Background: The objective of this review is to describe individual-level factors that influence and contribute to sick leave in healthcare, and especially hospital, settings. In doing so, to utilize relevant publications from the period 2004 – 2022 in order to provide a comprehensive and evidence-based resource for readers interested in effective human resource management and healthcare or hospital workforce planning. The review referred to studies on the determinants of absenteeism in the healthcare setting.Methods: To ensure that pertinent papers (2004 – 2022) were identified, a systematic literature review was performed searching Google Scholar, Econ Lit, PubMed, ResearchGate, ScienceDirect, Emerald Insight, Scopus, Medline, PsychInfo, and Web of Science. All abstracts were screened to identify papers that empirically investigated factors at individual level that are relevant to sickness absence in a healthcare population. A total of 494 papers were initially identified. These were reduced to 123 papers using pre-determined inclusion and exclusion criteria.Results: Individual-level factors such as age, gender, health, marital status, personality, tenure and job satisfaction have moderately strong associations with absence. There is a negative relationship between ageing, health status and absenteeism.Conclusions: The review concludes that consideration by administrators of the impact of ageing and life phases will assist greatly in strategic workforce planning in the healthcare sector. There are marked differences in rates of absenteeism by gender, specifically by life phase that should be considered in staffing decisions.

description: We reveal the nature of the avalanche collapse of the giant viable component in multiplex networks under perturbations such as random damage. Specifically, we identify latent critical clusters associated with the avalanches of random damage. Divergence of their mean size signals the approach to the hybrid phase transition from one side, while there are no critical precursors on the other side. We find that this discontinuous transition occurs in scale-free multiplex networks whenever the mean degree of at least one of the interdependent networks does not diverge.

description: In this paper we provide a \emph{global} investigation of the geometry of parallelizable manifolds (or absolute parallelism geometry) frequently used for application. We discuss the different linear connections and curvature tensors from a global point of view. We give an existence and uniqueness theorem for a remarkable linear connection, called the canonical connection. Different curvature tensors are expressed in a compact form in terms of the torsion tensor of the canonical connection only. Using the Bianchi identities, some interesting identities are derived. An important special fourth order tensor, which we refer to as Wanas tensor, is globally defined and investigated. Finally a double-view for the fundamental geometric objects of an absolute parallelism space is established: The expressions of these geometric objects are computed in the parallelization basis and are compared with the corresponding local expressions in the natural basis. Physical aspects of some geometric objects considered are pointed out.

description: This deliverable provides information about the implementation of an API to serve aggregated data from resources relevant to past large-scale disasters and the aggregation of data coming from internal sources and devices, such as smart glasses, smart helmets, drones, and sensors.
 As far as the past disasters are concerned, 7 relevant sources have been chosen that can be proven to be useful for crisis preparedness and search and rescue operations, after being evaluated according to specific criteria. Data aggregated and transformed from these sources are then served through an API to be used as part of a collective access point for the execution of experimental knowledge discovery algorithms.
 The second section of D4.8 aims to present the data aggregation mechanism. This section settles down the available components that enable the aggregation mechanisms that process the real-time data and combine them with rest data, such as historical data, data from COncORDE.

description: Using different optical setups based on squeezed state and photon subtraction we show how optical entanglement between a macroscopic and a microscopic state - the so-called Schrodinger cat state or micro-macro state - can be generated. The entangled state is heralded and is thus produced a priori in contrast to previous proposals. We define the macroscopicity of the macroscopic part of the state as their mean distance in phase space and the success rate in discriminating them with homodyne detection, and subsequently, based on these measures we investigate the macroscopicity of different states. Furthermore, we show that the state can be used to map a microscopic qubit onto a macroscopic one thereby linking a qubit processor with a qumode processor.

RG flows in d dimensions, the dilaton effective action, and the a-theorem

description: Motivated by the recent dilaton-based proof of the 4d a-theorem, we study the dilaton effective action for RG flows in d dimensions. When d is even, the action consists of a Wess-Zumino (WZ) term, whose Weyl-variation encodes the trace-anomaly, plus all Weyl-invariants. For d odd, the action consists of Weyl-invariants only. We present explicit results for the flat-space limit of the dilaton effective action in d-dimensions up to and including 8-derivative terms. GJMS-operators from conformal geometry motivate a form of the action that unifies the Weyl-invariants and anomaly-terms into a compact general-d structure. A new feature in 8d is the presence of an 8-derivative Weyl-invariant that pollutes the O(p^8)-contribution from the WZ action to the dilaton scattering amplitudes; this may challenge a dilaton-based proof of an a-theorem in 8d. We use the example of a free massive scalar for two purposes: 1) it allows us to confirm the structure of the d-dimensional dilaton effective action explicitly; we carry out this check for d=3,4,5,...,10; and 2) in 8d we demonstrate how the flow (a_UV - a_IR) can be extracted systematically from the O(p^8)-amplitudes despite the contamination from the 8-derivative Weyl-invariant. This computation gives a value for the a-anomaly of the 8d free conformal scalar that is shown to match the value obtained from zeta-function regularization of the log-term in the free energy.

Experimental scheme for qubit and qutrit symmetric informationally complete positive operator-valued measurements using multiport devices

description: It is crucial for various quantum information processing tasks that the state of a quantum system can be determined reliably and efficiently from general quantum measurements. One important class of measurements for this purpose is symmetric informationally complete positive operator-valued measurements (SIC-POVMs). SIC-POVMs have the advantage of providing an unbiased estimator for the quantum state with the minimal number of outcomes needed for full tomography. By virtue of Naimark's dilation theorem, any POVM can always be realized with a suitable coupling between the system and an auxiliary system and by performing a projective measurement on the joint system. In practice, finding the appropriate coupling is rather non-trivial. Here we propose an experimental design for directly implementing SIC-POVMs using multiport devices and path-encoded qubits and qutrits, the utility of which has recently been demonstrated by several experimental groups around the world. Furthermore, we describe how these multiports can be attained in practice with an integrated photonic system composed of nested linear optical elements.

description: One dimensional quantum mechanics problems, namely the infinite potential well, the harmonic oscillator, the free particle, the Dirac delta potential, the finite well and the finite barrier are generalized for finite arbitrary dimension in a radially symmetric, or angular invariant, manner. This generalization enables the Schrödinger equation solutions to be visualized for Bessel functions and Whittaker functions, and it also enables connections to multi-dimensional physics theories, like string theory.

The evolution of the f-mode instability in neutron stars and gravitational wave detectability

description: We study the dynamical evolution of the gravitational-wave driven instability of the f-mode in rapidly rotating relativistic stars. With an approach based on linear perturbation theory we describe the evolution of the mode amplitude and follow the trajectory of a newborn neutron star through its instability window. The influence on the f-mode instability of the magnetic field and the presence of an unstable r-mode is also considered. Two different configurations are studied in more detail; an N = 1 polytrope with a typical mass and radius and a more massive polytropic N = 0.62 model with gravitational mass M = 1.98 Msun. We study several evolutions with different initial rotation rates and temperature and determine the gravitational waves radiated during the instability. In more massive models, an unstable f-mode with a saturation energy of about 1e-6 Msun c^2 may generate a gravitational-wave signal which can be detected by the Advanced LIGO/Virgo detector from the Virgo cluster. The magnetic field affects the evolution and then the detectability of the gravitational radiation when its strength is higher than 1e12 G, while the effects of an unstable r-mode become dominant when this mode reaches the maximum saturation value allowed by non-linear mode couplings. However, the relative saturation amplitude of the f- and r-modes must be known more accurately in order to provide a definitive answer to this issue. From the thermal evolution we find also that the heat generated by shear viscosity during the saturation phase completely balances the neutrinos' cooling and prevents the star from entering the regime of mutual friction. The evolution time of the instability is therefore longer and the star loses significantly larger amounts of angular momentum via gravitational waves.

description: We study hardcore bosons on a triangular ladder at half filling in the presence of a frustrating hopping term and a competing nearest neighbor repulsion $V$ which promotes crystallization. Using the finite-size density-matrix renormalization group method, we obtain the phase diagram which contains three phases: a uniform superfluid (SF), an insulating charge density wave (CDW) crystal and a bond ordered insulator (BO). We find that the transitions from SF to CDW and SF to BO are continuous in nature, with critical exponents varying continously along the phase boundaries, while the transition from CDW to BO is found to be first order. The phase diagram is also shown to contain an exactly solvable Majumdar Ghosh point, and re-entrant SF to CDW phase transitions.

description: In this deliverable situational analysis and impact assessment are addressed with the development of an application, aiming at improving both and thus facilitating the task of decision making. The 3D Mixed Reality Command Centre application allows the decision-maker to enhance their situational awareness by blending the real world (what is happening around them in the command centre) with the virtual world by visualizing all the units and victims state during the search and rescue mission and additionally by live stream video from robots and UAV. The application allows timely decision-making by representing the spatial and chronological information in an easy-to-understand way. The application is developed for the Microsoft HoloLens 2 headset taking advantage of its natural user interface and communication capabilities. The development process of the application is presented with the system architecture and the description of its functionality.
