description: Graphene supports surface plasmon polaritons with comparatively slow propagation velocities in the THz region, which becomes increasingly interesting for future communication technologies. This ability can be used to realize compact antennas, which are up to two orders of magnitude smaller than their metallic counterparts. For a proper functionality of these antennas some minimum material requirements have to be fulfilled, which are presently difficult to achieve, since the fabrication and transfer technologies for graphene are still evolving. In this work we analyze available graphene materials experimentally and extract intrinsic characteristics at THz frequencies, in order to predict the dependency of the THz signal emission threshold as a function of the graphene relaxation time tau_r and the chemical potential mu_c.

Relativistic X-ray Lines from the Inner Accretion Disks Around Black Holes
Creators: name: Miller, J. M.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Relativistic X-ray emission lines from the inner accretion disk around black holes are reviewed. Recent observations with the Chandra X-ray Observatory, X-ray Multi-Mirror Mission-Newton, and Suzaku are revealing these lines to be good probes of strong gravitational effects. A number of important observational and theoretical developments are highlighted, including evidence of black hole spin and effects such as gravitational light bending, the detection of relativistic lines in stellar-mass black holes, and evidence of orbital-timescale line flux variability. In addition, the robustness of the relativistic disk lines against absorption, scattering, and continuum effects is discussed. Finally, prospects for improved measures of black hole spin and understanding the spin history of supermassive black holes in the context of black hole-galaxy co-evolution are presented. The best data and most rigorous results strongly suggest that relativistic X-ray disk lines can drive future explorations of General Relativity and disk physics.

Conserving liberalism : an interpretation of truth, hope and power in the philosophy of Karl Popper
Creators: name: Williams, Douglas E.
Publisher: name: University of British Columbia
Year: 2010

description: This study is an interpretation of the social and political thought and methodology of Karl Popper, one of the most heralded yet controversial philosophers of our time. The goal has been to provide a more coherent, accurate, and systematic account of Popper's thought and of its relevance to students of politics and society than currently exists by, first, emphasizing certain historical and contextual factors in connection with the structure and development of his ideas which rule out certain contemporary misunderstandings of his thought, and secondly, by allowing Popper's own formulations to take precedence over those of his commentators, regardless of their sympathies and estimate of Popper's massive intellectual legacy. It is my principal argument that the unity of Popper's philosophy lies in its moral dimension, his life long determination to conserve the intellectual foundations of hope and progress that human autonomy requires--the distinctively Kantian belief that mind can and should be decisive in practical affairs no less than in the struggle with nature, the twin pillars of the Enlightenment and modern liberalism alike. Given the nature of our times--a century of "total" wars, endless crises, and one intellectual revolution after another--such an endeavour is no small achievement. I have tried to capture the propositional cutting-edge of my interpretation of Popper's thought in the keywords of the subtitle of this study: that, without the belief in the possibility of objective truth--knowledge that is independent of whether we wish to acknowledge its existence or not, there is little hope in the future prospects of the "open societies" of the Western world, and that one of the gravest errors of the liberalism of the past was its underestimation of the need to institutionalise its best interests against the threat of many forms of illiberal power known in our time, particularly of the "unintended" variety. I accordingly argue that Popper's vision is best characterised as a combat-toughened conception of reality, and of the corresponding rationality necessary to survive, let alone to live well, as the Western tradition of political theory has held to be desirable.
Controlled enhancement or suppression of exchange biasing using impurity $δ$-layers

description: The effects of inserting impurity $δ$-layers of various elements into a Co/IrMn exchange biased bilayer, at both the interface, and at given points within the IrMn layer a distance from the interface, has been investigated. Depending on the chemical species of dopant, and its position, we found that the exchange biasing can be either strongly enhanced or suppressed. We show that biasing is enhanced with a dusting of certain magnetic impurities, present at either at the interface or sufficiently far away from the Co/IrMn interface. This illustrates that the final spin structure at the Co/IrMn interface is not only governed by interface structure/roughness but is also mediated by local exchange or anisotropy variations within the bulk of the IrMn.

description: We investigate the generation of Primordial Black Holes (PBHs) with the aid of gravitationally increased friction mechanism originated from the NonMinimal field Derivative Coupling (NMDC) to gravity framework, with the quartic potential. Applying the coupling parameter as a two-parted function of inflaton field and fine-tuning of five parameter assortments we can acquire ultra slow-roll phase to slow down the inflaton field due to high friction. This enables us to achieve enough enhancement in the amplitude of curvature perturbations power spectra to generate PBHs with different masses. The reheating stage is considered to obtain criteria for PBHs generation during radiation dominated era. We demonstrate that three cases of asteroid mass PBHs ($10^{-12}M_{\odot}$, $10^{-13}M_{\odot}$, and $10^{-15}M_{\odot})$ can be very interesting candidates for comprising $100\%$ , $98.3\%$ and $99.1\%$ of the total Dark Matter (DM) content of the universe. Moreover, we analyse the production of induced Gravitational Waves (GWs), and illustrate that their spectra of current density parameter $(Ω_{\rm GW_0})$ for all parameter Cases foretold by our model have climaxes which cut the sensitivity curves of GWs detectors, ergo the veracity of our outcomes can be tested in light of these detectors. At last, our numerical results exhibit that the spectra of $Ω_{\rm GW_0}$ behave as a power-law function with respect to frequency, $Ω_{\rm GW_0} (f) \sim (f/f_c)^{n} $, in the vicinity of climaxes. Also, in the infrared regime $f\ll f_{c}$, the power index satisfies the relation $n=3-2/\ln(f_c/f)$.

description: Through solution of the multielectron, semi-relativistic, time-dependent Schrödinger equation, we show that angular streaking produces strongly spin-polarized electrons in a noble gas. The degree of spin polarization increases with the Keldysh parameter, so that angular streaking -- ordinarily applied to investigate tunneling -- may be repurposed to generate strongly spin-polarized electron bunches. Additionally, we explore modifications of the angular streaking scheme that also enhance spin polarization.

description: We develop a new ab initio many-body approach capable of describing simultaneously both bound and scattering states in light nuclei, by combining the resonating-group method with the use of realistic interactions, and a microscopic and consistent description of the nucleon clusters. This approach preserves translational symmetry and Pauli principle. We present phase shifts for neutron scattering on 3H, 4He and 10Be and proton scattering on {3,4}He, using realistic nucleon-nucleon potentials. Our A=4 scattering results are compared to earlier ab initio calculations. We demonstrate that a proper treatment of the coupling to the n-10Be continuum is essential to explain the parity-inverted ground state in 11Be.

description: In my personal history, I was an ESO student between 2003 and 2005 and an "Operation Paid Associate" (OPA) between 2007 and 2008. As a student, I volunteered for duties which consisted in participating in the development of the pipeline of the Coudé Echelle Spectrograph (CES) then offered on the ESO 3.6m. As an "OPA", I supported all the instruments which were offered at that time at La Silla. This experience was critical in my involvement in development of astronomical instrumentation which would eventually lead me to be the first professor hired for this topic at the University of São Paulo, Brazil. In this talk, I will develop on my experience to demonstrate the role that telescopes located at La Silla Observatory can play in the education of the new generation of astronomers. In particular, I will focus on the need for hands-on experience on topics like data reduction or scheduling of observations.

description: We present MUSE, a software framework for combining existing computational tools for different astrophysical domains into a single multiphysics, multiscale application. MUSE facilitates the coupling of existing codes written in different languages by providing inter-language tools and by specifying an interface between each module and the framework that represents a balance between generality and computational efficiency. This approach allows scientists to use combinations of codes to solve highly-coupled problems without the need to write new codes for other domains or significantly alter their existing codes. MUSE currently incorporates the domains of stellar dynamics, stellar evolution and stellar hydrodynamics for studying generalized stellar systems. We have now reached a "Noah's Ark" milestone, with (at least) two available numerical solvers for each domain. MUSE can treat multi-scale and multi-physics systems in which the time- and size-scales are well separated, like simulating the evolution of planetary systems, small stellar associations, dense stellar clusters, galaxies and galactic nuclei. In this paper we describe three examples calculated using MUSE: the merger of two galaxies, the merger of two evolving stars, and a hybrid N-body simulation. In addition, we demonstrate an implementation of MUSE on a distributed computer which may also include special-purpose hardware, such as GRAPEs or GPUs, to accelerate computations. The current MUSE code base is publicly available as open source at http://muse.li

description: Extreme near-horizon geometries in D=11 supergravity preserving four supersymmetries are classified. It is shown that the Killing spinors fall into three possible orbits, corresponding to pairs of spinors defined on the spatial cross-sections of the horizon which have isotropy groups SU(3), G2, or SU(4). In each case, the conditions on the geometry and the 4-form flux are determined. The integrability conditions obtained from the Killing spinor equations are also investigated.

description: The ability to control the conductance of single molecules will have a major impact in nanoscale electronics. Azobenzene, a molecule that changes conformation as a result of a trans/cis transition when exposed to radiation, could form the basis of a light-driven molecular switch. It is therefore crucial to clarify the electrical transport characteristics of this molecule. Here, we investigate theoretically charge transport in a system in which a single azobenzene molecule is attached to two carbon nanotubes. In clear contrast to gold electrodes, the nanotubes can act as true nanoscale electrodes and we show that the low-energy conduction properties of the junction may be dramatically modified by changing the topology of the contacts between the nanotubes and the molecules, and/or the chirality of the nanotubes (that is, zigzag or armchair). We propose experiments to demonstrate controlled electrical switching with nanotube electrodes.

description: An almost radial gauge $A^\mathrm{ar}$ of the electromagnetic potential is constructed for which $x\cdot A^\mathrm{ar}(x)$ vanishes arbitrarily fast in timelike directions. This potential is in the class introduced by Dirac with the purpose of forming gauge-invariant quantities in quantum electrodynamics. In quantum case the construction of smeared operators $A^\mathrm{ar}(K)$ is enabled by a natural extension of the free electromagnetic field algebra introduced earlier (represented in a Hilbert space). The space of possible smearing functions $K$ includes vector fields with the asymptotic spacetime behavior typical for scattered currents (the conservation condition in the whole spacetime need not be assumed). This construction is motivated by a possible application to the infrared problem in QED.

We measure the inclusive branching fraction BF(B+ --> K+K-pi+) = [5.0+/-0.5(stat)+/-0.5(syst)]x10^-6. Inspection of the Dalitz plot of signal candidates shows a broad structure peaking near 1.5 GeV/c^2 in the K+K- invariant mass distribution. We find the direct CP asymmetry to be consistent with zero.

description: The Iqueye single-photon ultrafast photometer was mounted at the NTT for three runs, two in 2009 (January and December) and one in 2010 (July). Several objects with fast variability were observed. Here we focus on the light curves of the optical pulsars in Crab, Vela, and 0540-69 supernova remnants. The quality of the Iqueye light curves and accuracy of pulse phases allowed us to obtain the best light curves of these three pulsars and were instrumental to compare the optical profiles and timing with those determined at radio frequency, in the UV and at X/gamma-ray energies, and to study the emission geometry.

With its state-of-the-art lasers, it will carry out an ambitious and diverse research program. Activities at ELI Beamlines can be broken down in complementary areas of scientific interest: development and testing of novel technologies for multi-PW laser systems, plasma physics, high field physics experiments, production of femtosecond secondary sources of ionizing radiation (extreme ultraviolet radiation, X rays, gamma, electrons, and protons)to be used in interdisciplinary applications in physics, biology, medicine, and material sciences.In-house experiments are already taking place since the first half of 2018, first user calls and experiments started in 2019.In this contribution, the ELI Beamlines accelerator facility and its current status of operation are presented in more details. Particular attention is paid to the design and implementation of the radiation protection program, with emphasis on the unique challenges this laser facility poses in terms of radiation safety.

A study of Vancouver-Richmond meals-on-wheels
Creators: name: McKinnon, Mona Claire
Publisher: name: University of British Columbia
Year: 2010

description: Little is known about Meals-on-Wheels organizations, though they exist in many western countries. The purpose of this study is to examine the Vancouver-Richmond Meals-on-Wheels service as an organization and from that examination to provide information about clients, volunteers, staff, and organizational management. The literature was searched for guidance on the concept of Meals-on-Wheels. Was there any definition of an ideal organization? Similarly, discussions with government officials in the Province of British Columbia were conducted to determine what they thought this organization might contribute to the province's social support services. The prescriptions were vague and it was found that many assumptions were made. It seemed that organization theory might help to expose the gaps in these prescriptions. An examination of the organization by observation, interviews, use of secondary data for client profiles, questionnaires for volunteers, and interviews of present clients led to the development of a descriptive account which was arranged using a model developed by Donabedian to assess the quality of patient care, namely, inputs, process, structure, and outcomes. It became clear that organizational theory might assist in diagnosis of some managerial problems as the findings showed that client turnover was high. Analysis of available data had shown the clients to be in the category of "old, old," fairly evenly distributed throughout the area, and self-referred. Those volunteers who responded to a questiononaire were long-term, reasonably satisfied, and strongly committed. The clients interviewed were unstinting in their praise for the volunteers and appreciative of the service. They were dissatisfied with certain aspects of the food and their lack of opportunity for input into this aspect of Meals-on-Wheels. The employees found it difficult to communicate with the investigator and with other important community representatives. Internal and external relationships seemed to be tense. It seemed that by developing a prescription for "best practices" for a Meals-on-Wheels organization working in this context, comparisons of the existing organization with this prescription might assist with the diagnosis of managerial problems and lead to identification of possible remedies. This course was followed.
Incorporating postleap checks in tau-leaping

description: By explicitly representing the reaction times of discrete chemical systems as the firing times of independent, unit rate Poisson processes, we develop a new adaptive tau-leaping procedure. The procedure developed is novel in that accuracy is guaranteed by performing postleap checks. Because the representation we use separates the randomness of the model from the state of the system, we are able to perform the postleap checks in such a way that the statistics of the sample paths generated will not be biased by the rejections of leaps. Further, since any leap condition is ensured with a probability of one, the simulation method naturally avoids negative population values

description: We analyze deep inelastic scattering at small Bjorken x, using the approximate conformal invariance of QCD at high energies. Hard pomeron exchanges are resummed eikonally, restoring unitarity at large values of the phase shift in the dual AdS geometry. At weak coupling this phase is imaginary, corresponding to a black disk in AdS. In this saturated regime, cross sections exhibit geometric scaling and have a simple universal form, which we test against available experimental data for the proton structure function F_2(x,Q^2). We predict, in particular, the dependence of the cross section on the scaling variable (Q/Q_s)^2 in the deeply saturated region, where Q_s is the usual saturation scale. We find agreement with current data on F_2 in the kinematical region 0.5 < Q^2 < 10 GeV^2, x < 10^-2, with an average 6% accuracy. We conclude by discussing the relation of our approach with the commonly used dipole formalism.

description: We carried out low resolution spectroscopic observations in the wavelength range 3400-4700 A of 20 He-weak and 8 He-strong stars to determine their fundamental parameters by means of the Divan-Chalonge-Barbier (BCD) spectrophotometric system. For a few He-weak stars we also estimate the effective temperatures and the angular diameters by integrating absolute fluxes observed over a wide spectral range. Non-LTE model calculations are carried out to study the influence of the He/H abundance ratio on the emergent radiation of He-strong stars and on their Teff determination. We find that the effective temperatures, surface gravities and bolometric absolute magnitudes of He-weak stars estimated with the BCD system and the integrated flux method are in good agreement between each other, and they also agree with previous determinations based on several different methods. The mean discrepancy between the visual absolute magnitudes derived using the Hipparcos parallaxes and the BCD values is on average 0.3 mag for He-weak stars, while it is 0.5 mag for He-strong stars. For He-strong stars, we note that the BCD calibration, based on stars in the solar environment, leads to overestimated values of Teff. By means of model atmosphere calculations with enhanced He/H abundance ratios we show that larger He/H ratios produce smaller BD which naturally explains the Teff overestimation. We take advantage of these calculations to introduce a method to estimate the He/H abundance ratio in He-strong stars. The BD of HD 37479 suggests that the Teff of this star remains fairly constant as the star spectrum undergoes changes in the intensity of H and He absorption lines. Data for the He-strong star HD 66765 are reported for the first time.

description: SOXS (Son Of X-Shooter) will be a spectrograph for the ESO NTT telescope capable
to cover the optical and NIR bands. SOXS will be built and run by an international consortium,
carrying out rapid and longer term Target of Opportunity requests on a variety of astronomical
objects. SOXS will observe all kind of transient and variable sources from different surveys. These
will be a mixture of fast alerts (e.g. gamma-ray bursts, gravitational waves, neutrino events), mid-
term alerts (e.g. supernovae, X-ray transients), fixed time events (e.g. close-by passage of minor
bodies). While the focus is on transients and variables, still there is a wide range of other
astrophysical targets and science topics that will benefit from SOXS. The design foresees a
spectrograph with a Resolution-Slit product ≈ 4500, capable of simultaneously observing over the
entire band the complete spectral range from the U- to the H-band. The limiting magnitude of R~20
(1 hr at S/N~10) is suited to study transients identified from on-going imaging surveys. Light imaging
capabilities in the optical band (grizy) are also envisaged to allow for multi-band photometry of the
faintest transients. With SOXS, the NTT will be specialized for studying the transients, in strong
synergy and ideal timing with many upcoming ground and space based facilities for transient
discovery.

A discussion of clarinet solo material, representative of four periods and/or styles in the development of the clarinet repertoire, is featured: an unaccompanied twentieth-century work, Heinrich Sutermeister's Capriccio; an early classical concerto, Karl Stamitz's Concerto in E-flat Major; a French Conservatory Contest Piece, Charles Lefebvre's Fantaisie-Caprice; and a late romantic sonata, Johannes Brahms' Sonata in E-flat Major, Op. 120, No. 2. Sutermeister's Capriccio (1946), for A clarinet, was commissioned as a contest piece for the Geneva Conservatory. The composition is of a quality particularly suitable for a contest, for two contrasting ideas permeate the entire work: one is rough and crisp with staccato passages; the other is smooth and calm with legato passages. It is this writer's opinion that Capriccio reflects the influence of Sutermeister's cinematic works. Karl Stamitz's Concerto in E-flat reflects the features of the French school of clarinet playing as exhibited by the first well-known clarinet virtuoso, Joseph Beer. This concerto also shows the influence of Mozart, as many mutual features occur between Stamitz's Concerto in E-flat and Mozart's Concerto in A. Significant contributions to woodwind literature have been made by French composers. This is, in part, attributable to the Paris Conservatory, which since the late nineteenth century has commissioned French composers to write contest pieces for the final performance examinations. Such works have included Debussy's Première Rhapsodie, and Lefebvre's Fantaisie-Caprice. Johannes Brahms' fascination with Richard Mühlfeld, eminent clarinetist of the Meiningen Orchestra, manifests itself in four chamber works he wrote for the clarinet. Brahms' Clarinet Quintet Op. 115 is regarded as one of his greatest masterpieces. The Two Sonatas for Clarinet and Piano Op. 120 offer quite a contrast. The first, in F minor, is predominantly the more passionate of the two, whereas the second, in E-flat major, is of greater intimacy of expression.

description: Coronavirus disease 2019 (COVID-19) is one of the most infectious diseases and one of the greatest challenge due to global health crisis. The virus has been transmitted globally and spreading so fast with high incidence. While, the virus still pandemic, the government scramble to seek antiviral treatment and vaccines to combat the diseases. This study was conducted to investigate the influence of air pressure, air temperature, and relative humidity on the number of confirmed cases in COVID-19. Based on the result, the calculation of reproduced correlation through path decompositions and subsequent comparison to the empirical correlation indicated that the path model fits the empirical data. The identified factor significantly influenced the number of confirmed cases of COVID-19. Therefore, the number of daily confirmed cases of COVID-19 may reduce as the amount of relative humidity increases; relative humidity will increase as the amount of air temperature decreases; and the amount of air temperature will decrease as the amount of air pressure decreases. Thus, it is recommended that policy-making bodies consider the result of this study when implementing programs for COVID-19 and increase public awareness on the effects of weather condition, as it is one of the factors to control the number of COVID-19 cases.
Generalized Navier Boundary Condition and Geometric Conservation Law for surface tension

description: We consider two-fluid flow problems in an Arbitrary Lagrangian Eulerian (ALE) framework. The purpose of this work is twofold. First, we address the problem of the moving contact line, namely the line common to the two fluids and the wall. Second, we perform a stability analysis in the energy norm for various numerical schemes, taking into account the gravity and surface tension effects. The problem of the moving contact line is treated with the so-called Generalized Navier Boundary Conditions. Owing to these boundary conditions, it is possible to circumvent the incompatibility between the classical no-slip boundary condition and the fact that the contact line of the interface on the wall is actually moving. The energy stability analysis is based in particular on an extension of the Geometry Conservation Law (GCL) concept to the case of moving surfaces. This extension is useful to study the contribution of the surface tension. The theoretical and computational results presented in this paper allow us to propose a strategy which offers a good compromise between efficiency, stability and artificial diffusion.

Baryon-driven decontraction in Milky Way mass haloes

description: We select a sample of Milky Way (MW) mass haloes from a high-resolution version of the EAGLE simulation to study their inner dark matter (DM) content and how baryons alter it. As in previous studies, we find that all haloes are more massive at the centre compared to their DM-only (DMO) counterparts at the present day as a result of the dissipational collapse of baryons during the assembly of the galaxy. However, we identify two processes that can reduce the central halo mass during the evolution of the galaxy. Firstly, gas blowouts induced by AGN feedback can lead to a substantial decrease of the central DM mass. Secondly, the formation of a stellar bar and its interaction with the DM can induce a secular expansion of the halo; the rate at which DM is evacuated from the central region by this process is related to the average bar strength and the timescale on which it acts determines how much the halo has decontracted. Although the inner regions of the haloes we have investigated are still more massive than their DMO counterparts at $z = 0$, they are significantly less massive than in the past and less massive than expected from the classic adiabatic contraction model. Since the MW has both a central supermassive black hole and a bar, the extent to which its halo has contracted is uncertain. This may affect estimates of the mass of the MW halo and of the expected signals in direct and indirect DM detection experiments.

description: We present a new class of irregular low-density parity-check (LDPC) codes for moderate block lengths (up to a few thousand bits) that are well-suited for rate-compatible puncturing. The proposed codes show good performance under puncturing over a wide range of rates and are suitable for usage in incremental redundancy hybrid-automatic repeat request (ARQ) systems. In addition, these codes are linear-time encodable with simple shift-register circuits. For a block length of 1200 bits the codes outperform optimized irregular LDPC codes and extended irregular repeat-accumulate (eIRA) codes for all puncturing rates 0.6~0.9 (base code performance is almost the same) and are particularly good at high puncturing rates where good puncturing performance has been previously difficult to achieve.

Astronomy and History. What time could tell us on the astronomical facilities in Chile
Creators: name: Silva, Barbara K.
Publisher: name: Zenodo
Year: 2019

description: We all know history and astronomy are two different areas of knowledge.
Nonetheless, both work with time, as they question a past that is gone forever. Astronomy does so
with starlight; history does it with ancient –or old- documents. Moreover, astronomy has its own
temporality, as it has changed throughout time, even if we reflect on the last decades. In the light of
this, fifty years have passed since ESO's inauguration; therefore this commemoration gives us an
advantage to think of the relationship between international astronomy and Chile. History can
illuminate ESO's past, letting us understand how this organization settled here and contributed to
what astronomy is today in the country. On the other side, ESO's history can show us a different
perspective on Chilean recent past, and we can visit these past five decades through the eyes of
science. We can situate this story at a crossroads: by bringing together the history of science,
technology, politics, international relations, and culture we can begin to understand this surprising
and extraordinary story of ESO, Chile and astronomy. As time does not stop its course, being aware
of this story can enhance our ability to understand we are still writing part of the history of
astronomy.

description: We prove that multimodal maps with an absolutely continuous invariant measure have exponential return time statistics around a.e. point. We also show a `polynomial Gibbs property' for these systems, and that the convergence to the entropy in the Ornstein-Weiss formula has normal fluctuations. These results are also proved for equilibrium states of some Hoelder potentials.

Demonstrating Majorana non-Abelian properties using fast adiabatic charge-transfer

description: Demonstration of Majorana non-Abelian properties is a major challenge in the field of topological superconductivity. In this work, we propose a minimal device and protocol for testing non-Abelian properties using charge-transfer operations between a quantum dot and two Majorana bound states combined with reading the parity state using a second dot. We use an adiabatic perturbation theory to find fast adiabatic paths to perform operations and to account for nonadiabatic errors. We find the ideal parameter sweep and a region in parameter space which reduces the charge-transfer operation time 1-2 orders of magnitude with respect to constant velocity driving. Using realistic parameters, we estimate that the lower bound for the time scale can be reduced to $\sim10$ ns. Deviations from the ideal parameters lead to the accumulation of an undesired dynamical phase, affecting the outcome of the proposed protocol. We furthermore suggest to reduce the influence from the dynamical phase using a flux echo. The echo protocol is based on the $4π$-periodicity of the topological state, absent for trivial bound states.
