Case studies in decadal climate predictability

description: It is well established that, based on knowledge of the initial conditions, important aspects of climate are predictable up to a year ahead. This predictability is primarily associated with the El Niño Southern Oscillation (ENSO). But is climate predictable further ahead? To what extent does knowledge of initial conditions constrain longer-term climate forecasts? In this study we investigate whether there is evidence that climate variables are potentially predictable beyond the generally accepted limit of ENSO predictability. Recognising that predictability is likely to be dependent on initial conditions we consider model-based case studies rather than measures of average predictability. The atmosphere-ocean coupled Hadley Centre HadCM3 model was used in this work. Starting from a pre-indstrial state, a single run was integrated with observed changes in greenhouse gases, volcanic aerosols and the solar cycle for the period 1860-1950. Still using observed forcings, an ensemble of five members was started from the 1950 state and integrated for another 50 years. Each case study consists of two further ensembles started with contemporaneous intial conditions from two different members of the five member ensemble. Four case studies have been completed using ensemble members with opposing large, persistent, regional differences in sea surface temperatures and ocean heat content. The results show clear evidence that knowledge of initial conditions can constrain predictions of climate variables beyond ENSO predictability. In the particular case studies considered, the aspects of climate that are predictable include North Atlantic sea surface temperatures, western European and southeastern US 1.5m temperatures, tropical and subtropical precipitation inthe Pacific and tropical precipitation in the Atlantic. However, predictability of climate variables is strongly dependent on the initial conditions. What are the mechanisms that give rise to these predictable signals? In most cases it seems to be simple persistence of ocean heat content anomalies, but there is also evidence of other mechanisms including ocean dynamics and ocean-atmosphere interaction. We are carrying out further work to interpret and clarify these mechanisms.

description: In a Bell experiment, it is natural to seek a causal account of correlations wherein only a common cause acts on the outcomes. For this causal structure, Bell inequality violations can be explained only if causal dependencies are modelled as intrinsically quantum. There also exists a vast landscape of causal structures beyond Bell that can witness nonclassicality, in some cases without even requiring free external inputs. Here, we undertake a photonic experiment realizing one such example: the triangle causal network, consisting of three measurement stations pairwise connected by common causes and no external inputs. To demonstrate the nonclassicality of the data, we adapt and improve three known techniques: (i) a machine-learning-based heuristic test, (ii) a data-seeded inflation technique generating polynomial Bell-type inequalities and (iii) entropic inequalities. The demonstrated experimental and data analysis tools are broadly applicable paving the way for future networks of growing complexity.

description: The synchronization of dust acoustic waves to an external periodic source is studied in the framework of a driven Korteweg-de Vries-Burgers equation that takes into account the appropriate nonlinear and dispersive nature of low frequency waves in a dusty plasma medium. For a spatio-temporally varying source term the system is shown to demonstrate harmonic (1:1) and super-harmonic (1:2) synchronized states. The existence domains of these states are delineated in the form of Arnold tongue diagrams in the parametric space of the forcing amplitude and forcing frequency and their resemblance to some past experimental results is discussed.

description: We study the $\bar b \bar b u d$ tetraquark with quantum numbers $I(J^P) = 0(1^+)$ as well as the $\bar b \bar b u s$ tetraquark with quantum numbers $J^P = 1^+$ using lattice QCD. We improve on existing work by including both local and scattering interpolating operators on both sides of the correlation functions and use symmetric correlation matrices. This allows not only a reliable determination of the energies of QCD-stable tetraquark ground states, but also of low-lying excited states, which are meson-meson scattering states. The latter is particularly important for future finite-volume scattering analyses. Here, we perform chiral and continuum extrapolations of just the ground-state energies, for which finite-volume effects are expected to be small. Our resulting tetraquark binding energies, $-100 \pm 10\:^{+36}_{-51}\:\:{\rm MeV}$ for $\bar b \bar b u d$ and $-30 \pm 3\:^{+11}_{-31}\:\:{\rm MeV}$ for $\bar b \bar b u s$, are consistent with other recent lattice-QCD predictions.

description: We present the complete family of solutions of 3D gravity (Lambda<0) with two asymptotically AdS exterior regions. The solutions are constructed from data at the two boundaries, which correspond to two independent and arbitrary stress tensors T_R, \bar T_R, and T_L, \bar T_L. The two exteriors are smoothly joined on to an interior region through a regular horizon. We find CFT duals of these geometries which are entangled states of two CFT's. We compute correlators between general operators at the two boundaries and find perfect agreement between CFT and bulk calculations. We calculate and match the CFT entanglement entropy (EE) with the holographic EE which involves geodesics passing through the wormhole. We also compute a holographic, non-equilibrium entropy for the CFT using properties of the regular horizon. The construction of the bulk solutions here uses an exact version of Brown-Henneaux type diffeomorphisms which are asymptotically nontrivial and transform the CFT states by two independent unitary operators on the two sides. Our solutions provide an infinite family of explicit examples of the ER=EPR relation of Maldacena and Susskind [arXiv:1306.0533].

RG flows in de Sitter: c-functions and sum rules

Year: 2024
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study the renormalization group flow of unitary Quantum Field Theories on two-dimensional de Sitter (dS) spacetime. We prove the existence of two functions of the radius of dS that interpolate between the central charges of the UV and IR fixed points of the flow when tuning the radius $R$ while keeping the mass scales fixed. The first is constructed from certain components of the two-point function of the stress tensor evaluated at antipodal separation. The second is the spectral weight of the stress tensor in the $Δ=2$ discrete series. This last fact implies that the stress tensor of any unitary QFT in dS$_2$ must interpolate between the vacuum and states in the $Δ=2$ discrete series irrep. We verify that the c-functions are monotonic for intermediate radii in the free massive boson and free massive fermion theories, but we lack a general proof of said monotonicity. We derive a variety of sum rules that relate the central charges and the c-functions to integrals of the two-point function of the trace of the stress tensor and to integrals of its spectral densities. The positivity of these formulas implies $c^{\text{UV}}\geq c^{\text{IR}}$. In the infinite radius limit the sum rules reduce to the well known formulas in flat space. Throughout the paper, we prove some general properties of the spectral decomposition of the stress tensor in dS$_{d+1}$.

description: We investigate brane-world models in different viable $F(R)$ gravity theories where the Lagrangian is an arbitrary function of the curvature scalar. Deriving the warped metric for this model, resembling Randal-Sundrum (RS) like solutions, we determine the graviton KK modes. The recent observations at the LHC, which constrain the RS graviton KK modes to a mass range greater than 3 TeV, are incompatible to RS model predictions. It is shown that the models with $F(R)$ gravity in the bulk address the issue which in turn constrains the $F(R)$ model itself.

description: A dark matter model based on QCD-like $SU(N_c)$ gauge theory with electroweakly interacting dark quarks is discussed. Assuming the dark quark mass $m$ is smaller than the dynamical scale $Λ_d \sim 4πf_d$, the main component of the dark matter is the lightest $G$-parity odd dark pion associated with chiral symmetry breaking in the dark sector. We show that nonzero dark quark mass induces the universal mass contribution to both $G$-parity odd and even pions, and their masses tend to be degenerate. As a result, dark pion annihilation into heavier $G$-parity even dark pion also affects the dark matter relic abundance. Thus, our setup naturally accommodates forbidden dark matter scenario and realizes heavy dark matter whose mass is ${\cal O}(1$-$100)~{\rm TeV}$, which is different from conventional electroweakly interacting dark matter such as minimal dark matter. We also discuss CP-violation from $θ$-term in the dark gauge sector and find that the predicted size of electron electric dipole moment can be as large as $\sim 10^{-32}~e~{\rm cm}$.

description: A single qutrit with transitions selectively driven by weakly-coupled reservoirs can implement one of the world's smallest refrigerators. We analyze the performance of $N$ such fridges that are collectively coupled to the reservoirs. We observe a quantum boost, manifest in a quadratic scaling of the steady-state cooling current with $N$. As $N$ grows further, the scaling reduces to linear, since the transitions responsible for the quantum boost become energetically unfavorable. Fine-tuned inter-qutrit interactions may be used to maintain the quantum boost for all $N$ and also for not-perfectly collective scenarios.

description: There is plenty of evidence in the literature of significant discrepancies between the observations and models of metal-poor red giant branch stars, in particular regarding the effective temperature, teff, scale. We revisit the benchmark star HD 122563 using the most recent observations from Gaia Data Release 3, to investigate if these new constraints may help in resolving this discrepancy. We review the most recent spectroscopic determinations of the metallicity of HD 122563 [Fe/H], and provide a new assessment of its fundamental parameters, i.e. bolometric luminosity, teff, surface gravity, plus a photometric determination of its metal content. Using these constraints, we compare the position of the star in the Hertzsprung-Russell (H-R) diagram with various recent sets of stellar evolution tracks. The H-R diagram analysis reveals a significant disagreement between observed and theoretical teff values, when adopting the most recent spectroscopic estimate of [Fe/H]. On the other hand, by using the photometric determination of [Fe/H] some of the selected sets of stellar tracks appear in fair agreement with observations. The sets with discrepant teff can be made to agree with observations either by modifying the prescription adopted to calculate the models' outer boundary conditions, and/or by reducing the adopted value of the mixing length parameter with respect to the solar-calibration. A definitive assessment of whether the teff scale of metal-poor stellar red giant branch models is consistent with observations requires an even more accurate determination of the fundamental parameters of HD 122563 and also a larger sample of calibrators. From the theoretical side, it is crucial to minimise the current uncertainties in the treatment (boundary conditions, temperature gradient) of the outer layers of stellar models with convective envelopes.

description: Charged particle acceleration using solid-state nanostructures has attracted attention in recent years as a method of achieving ultra-high-gradient acceleration in the TV/m domain. More concretely, metallic hollow nanostructures could be suitable for particle acceleration through the excitation of wakefields by a laser or a high-intensity charged particle beam in a high-density solid-state plasma. For instance, due to their special channelling properties as well as optoelectronic and thermo-mechanical properties, carbon nanotubes could be an excellent medium for this purpose. This article investigates the feasibility of generating ultra-high gradient acceleration using carbon nanotube arrays, modelled as solid-state plasmas in conventional particle-in-cell simulations performed in a two-dimensional axisymmetric quasi}-3D geometry. The generation of beam-driven plasma wakefields depending on different parameters of the solid structure is discussed in detail. Furthermore, by adopting an effective plasma-density approach, existing analytical expressions, originally derived for homogeneous plasmas, can be used to describe wakefields driven in periodic non-uniform plasmas.

description: We classify effective actions for Nambu-Goldstone (NG) bosons assuming absence of anomalies. Special attention is paid to Lagrangians invariant only up to a surface term, shown to be in a one-to-one correspondence with Chern-Simons (CS) theories for unbroken symmetry. Without making specific assumptions on spacetime symmetry, we give explicit expressions for these Lagrangians, generalizing the Berry and Hopf terms in ferromagnets. Globally well-defined matrix expressions are derived for symmetric coset spaces of broken symmetry. The CS Lagrangians exhibit special properties, on both the perturbative and the global topological level. The order-one CS term is responsible for non-invariance of canonical momentum density under internal symmetry, known as the linear momentum problem. The order-three CS term gives rise to a novel type of interaction among NG bosons. All the CS terms are robust against local variations of microscopic physics.

Deliverable D3.4 Final architecture and deployment results: Achieved results in the final architecture, technologies and infrastructure deployment
Creators: name: Maknavicius, Linas
Publisher: name: Zenodo
Year: 2021

description: This report provides the final update out of four planned for the 5G-TOURS project presenting work performed in WP3 "Network architecture and deployment". The scope of this deliverable is to report on the overall progress made in the 5G-TOURS network and system architecture and innovative technologies for the 5G network deployment in three trial sites (Turin, Rennes, and Athens). This report focuses on the following aspects: • Finalization of the baseline network architecture which encompasses 5G EVE platform, relevant standards components and 5G-TOURS innovations, as well as architecture instantiation per trial site and interactions with vertical players. • The technology evolutions conceived in the 5G-TOURS project, their implementation results, Service Layer components and theirs SDK descriptions. • The final set of the network infrastructure deployments on each trial site. In particular, several important outcomes from the architectural work, network innovations and trial deployments can be highlighted. Firstly, a comprehensive architectural setup was designed to suit vertical actors’ needs, facing 5G-TOURS Service Layer (which integrates useful network exposure functions for the service “closed loop” e.g. KPI monitoring), incorporating 5G EVE interworking gear (for service onboarding through 5G EVE portal) and/or direct connection to local MANO functions (where exposure of specific functionalities is needed directly towards the Service layer). Then, specific 5G-TOURS network innovations were devised, such as Artificial Intelligence functions for network resource forecasting, dynamic slicing and orchestration support (showcased through successful Proof-of-Concept demos prepared by several partners), some others directly integrated within a selection use cases, e.g. state-of-the-art solution for the 5G broadcast support (in Turin site), Enhanced MANO extensions (largely deployed in Athens trial). Also, open-source initiatives were developed for the Service Layer to support some of these technologies, with SDK and API documentation, and release of full open-source software solutions and largely publicized, e.g., AI Agents for OSM. Finally, thorough design and deployment of complex network setup was achieved in three trial sites, integrating equipment, system solutions and application software from different suppliers towards in-the-field realization of a set of distinct use cases which improve citizen lives: media and touristic applications in a world heritage protected environment (Turin site), novel 5G mmWave radio solution and eHealth appliances' integration within restricted hospital environment (in Rennes site, one of the first experimental eHealth deployments in Europe), mobilityefficient city applications with full integration of diagnostic / network measurement extensions to achieve "closed loop" between Service layer and networking (in Athens site).

description: Context. Near-Earth objects (NEOs) on an impact course with Earth can move at high angular speed. Understanding their properties, including rotation state, is crucial for assessing impact risks and mitigation strategies. Traditional photometric methods face challenges in collecting data on fast-moving NEOs accurately. Aims. This study introduces an innovative approach to aperture photometry tailored to analyzing trailed images of fast-moving NEOs. Our primary aim is to extract rotation state information from these observations, particularly focusing on the efficacy of this technique for fast rotators. Methods. We applied our approach to analyze the trailed images of three asteroids: 2023 CX1, 2024 BX1, and 2024 EF, which were either on a collision courses or performing a close fly-by with Earth. By adjusting aperture sizes, we controlled the effective exposure times to increase the sampling rates of the photometric variations. This enabled us to detect short rotation periods that would be challenging with conventional methods. Results. Our analysis revealed that trailed photometry significantly reduces overhead time associated with CCD read-out, enhancing the sampling rate of the photometric variations. We demonstrated that this technique is particularly effective for fast-moving objects, providing reliable photometric data when the object is at its brightest and closest to Earth. For asteroid 2024 BX1, we detected a rotation period as short as 2.5888 +- 0.0002 seconds, the fastest ever recorded. Our findings underscore the efficacy of trailed observations coupled with aperture photometry for studying the rotation characteristics of small NEOs, offering crucial insights for impact risk assessment and mitigation strategies.

description: We investigate the connection between local structure and dynamical heterogeneity in supercooled liquids. Through the study of four different models we show that the correlation between a particle's mobility and the degree of local order in nearby regions is highly system dependent. Our results suggest that the correlation between local structure and dynamics is weak or absent in systems that conform well to the mean-field picture of glassy dynamics and strong in those that deviate from this paradigm. Finally, we investigate the role of order-agnostic point-to-set correlations and reveal that they provide similar information content to local structure measures, at least in the system where local order is most pronounced.

description: This paper studies the stability of weak dispersive shock profiles for a quantum hydrodynamics system in one space dimension with nonlinear viscosity and dispersive (quantum) effects due to a Bohm potential. It is shown that, if the shock amplitude is sufficiently small, then the profiles are spectrally stable. This analytical result is consistent with numerical estimations of the location of the spectrum (Lattanzio, Zhelyazov, Math. Models Methods Appl. Sci. 31, 2021). The proof is based on energy estimates at the spectral level, on the choice of an appropriate weighted energy function for the perturbations involving both the dispersive potential and the nonlinear viscosity, and on the montonicity of the dispersive profiles in the small-amplitude regime.

description: We study the problem of efficiently constructing a curve C of genus 2 over a finite field F for which either the curve C itself or its Jacobian has a prescribed number N of F-rational points. In the case of the Jacobian, we show that any `CM-construction' to produce the required genus-2 curves necessarily takes time exponential in the size of its input. On the other hand, we provide an algorithm for producing a genus-2 curve with a given number of points that, heuristically, takes polynomial time for most input values. We illustrate the practical applicability of this algorithm by constructing a genus-2 curve having exactly 10^2014 + 9703 (prime) points, and two genus-2 curves each having exactly 10^2013 points. In an appendix we provide a complete parametrization, over an arbitrary base field k of characteristic neither 2 nor 3, of the family of genus-2 curves over k that have k-rational degree-3 maps to elliptic curves, including formulas for the genus-2 curves, the associated elliptic curves, and the degree-3 maps.

Just the ticket : the role of activism in shaping Austin’s future light rail system

Activism

description: This report is an examination of how activists have influenced Austin’s future light rail system and expanded bus system, Project Connect. The project provides an extraordinary opportunity to increase mobility, accessibility, and justice for transit users throughout Austin. Great transit provides people with more than just the ability to move between desired destinations quickly and easily; it allows people to fully participate in urban society and transcend the mobility restrictions which define their social class and way of life. However, market and political forces often seek to use light rail specifically as a chance to earn profit, disregarding the goal of improving the lives of marginalized communities. A light rail project that strives to make a city more attractive to increasingly mobile international capital and elevate the city to the world stage can have a negative effect on equity and cause a race to the bottom among competitive mid-level cities. Light rail has a particularly distinct history of causing gentrification and displacement in lower income neighborhoods and communities of color. The author conducted semi-structured interviews with activists, advocates, and agency staff to gain a better understanding of how activism has shaped, does shape, and will shape Project Connect and combat the exploitative forces that seek to use light rail transit solely for economic gain. Interviewees conveyed the importance of activism in almost every step of Project Connect. By engaging in traditional activism (representing their communities and acting as a check on agency power), shaping the Project Connect initial investment that was put forth to voters, influencing the governance structure of the project, demanding a first of its kind anti-displacement fund, ensuring high quality worker protections, fighting for an equitable fare structure, maintaining momentum and positive energy for the project, and creating a permanent seat at the decision making table, activists provide a crucial counterbalance to the market and political forces that seek to use Project Connect as a tool for capital accumulation.

description: Classical integrable impurities associated to high rank (gl_N) algebras are investigated. A particular prototype i.e. the vector non-linear Schrödinger (NLS) model is chosen as an example. A systematic construction of local integrals of motion as well as the time components of the corresponding Lax pairs is presented based on the underlying classical algebra. Suitable gluing conditions compatible with integrability are also extracted. The defect contribution is also examined in the case where non-trivial integrable conditions are implemented. It turns out that the integrable boundaries may drastically alter the bulk behavior, and in particular the defect contribution.

Mulit-year Predictability of Greenland Sea Spring Sea-ice Volume in a Coupled Climate Model

description: Prediction of sea-ice is not only important for shipping but also for weather as it can have a signicant climatic impact. Therefore sea-ice predictions are important for accurate inter-annual to decadal prediction of climate in coupled climate models. However, to our knowledge there has been little work on how predictable sea-ice is in a coupled atmosphere-ocean-ice model. We have studied the predictability of sea-ice in HadCM3 using case study ensemble experiments with external forcing from the late 20th century designed to emphasize the predictability in the climate system due to initial conditions. Here, we will concentrate on spring (maximum) ice-volume in a box in the Greenland Sea (30W to 10E, 68N to 80N). Model climatology from a control-run shows that this region has high inter-annual variability in sea-ice volume. We find that although ice may almost completely disappear from this area in late autumn, the same anomalies re-appear in the following spring for at least the first four years in three out of four case studies. The mechanism for this appears to be related to persistence of ocean heat content in the initial conditions and the state of the meridional overturning circulation and its associated heat transport. In this model, the atmosphere appears to less important than the ocean in determining the predictability of sea-ice volume in the Greenland Sea.

description: We study optimal synchronization in networks of heterogeneous phase oscillators. Our main result is the derivation of a synchrony alignment function that encodes the interplay between network structure and oscillators' frequencies and can be readily optimized. We highlight its utility in two general problems: constrained frequency allocation and network design. In general, we find that synchronization is promoted by strong alignments between frequencies and the dominant Laplacian eigenvectors, as well as a matching between the heterogeneity of frequencies and network structure.

description: Core-collapse Supernovae (CCSNe) are considered the primary magnetar formation channel, with 15 magnetars associated with supernova remnants (SNRs). A large fraction of these should occur in massive stellar binaries that are disrupted by the explosion, meaning that $\sim45\%$ of magnetars should be nearby high-velocity stars. Here we conduct a multi-wavelength search for unbound stars, magnetar binaries, and SNR shells using public optical ($uvgrizy-$bands), infrared ($J-$, $H-$, $K-$, and $K_s-$bands), and radio ($888$ MHz, $1.4$ GHz, and $3$ GHz) catalogs. We use Monte Carlo analyses of candidates to estimate the probability of association with a given magnetar based on their proximity, distance, proper motion, and magnitude. In addition to recovering a proposed magnetar binary, a proposed unbound binary, and 13 of 15 magnetar SNRs, we identify two new candidate unbound systems: an OB star from the Gaia catalog we associate with SGR J1822.3-1606, and an X-ray pulsar we associate with 3XMM J185246.6+003317. Using a Markov-Chain Monte Carlo simulation that assumes all magnetars descend from CCSNe, we constrain the fraction of magnetars with unbound companions to $5\lesssim f_u \lesssim 24\%$, which disagrees with neutron star population synthesis results. Alternate formation channels are unlikely to wholly account for the lack of unbound binaries as this would require $31\lesssim f_{nc} \lesssim 66\%$ of magnetars to descend from such channels. Our results support a high fraction ($48\lesssim f_m \lesssim 86\%$) of pre-CCSN mergers, which can amplify fossil magnetic fields to preferentially form magnetars.
