description: Observations of heavy (${\simeq}2\,M_\odot$) neutron stars in addition to the recent measurement of tidal deformability from the binary neutron-star merger GW170817, place interesting constraints on theories of dense matter. Current and future observatories, such as the NICER and ATHENA are expected to collect information on the global parameters of neutron stars, namely masses and radii, with the accuracy of a few percent. Such accuracy will allow for precise comparisons of measurements to models of compact objects. Here we investigate how the measurement accuracy of the NICER and ATHENA missions will improve our understanding of the dense-matter interior of neutron stars. We compare global parameters of stellar configurations obtained using three different equations of state: a reference (SLy4 EOS) and two piecewise polytropes manufactured to produce mass-radius relations indistinguishable from the observational point of view i.e. within the predicted error of the radius measurement. We assume observational errors on the radius determination corresponding to the expected accuracies. The effect of rotation is examined using high-precision numerical relativity computations. Due to the fact that masses and rotational frequencies might be determined very precisely in the most optimistic scenario, only the influence of observational errors on the radius measurements is investigated. We show that ${\pm}5\%$ errors in radius measurement lead to ${\sim}10\%$ and ${\sim}40\%$ accuracy in central parameter estimation, for low-mass and high-mass neutron stars, respectively. Global parameters, such as oblateness and surface area, can be established with $8-10\%$ accuracy, even if only compactness (instead of mass and radius) is measured. We also report on the range of tidal deformabilities corresponding to the estimated masses of GW170817, for the assumed uncertainty in radius.

description: This monograph deals with adaptive supervised classification, using tools borrowed from statistical mechanics and information theory, stemming from the PACBayesian approach pioneered by David McAllester and applied to a conception of statistical learning theory forged by Vladimir Vapnik. Using convex analysis on the set of posterior probability measures, we show how to get local measures of the complexity of the classification model involving the relative entropy of posterior distributions with respect to Gibbs posterior measures. We then discuss relative bounds, comparing the generalization error of two classification rules, showing how the margin assumption of Mammen and Tsybakov can be replaced with some empirical measure of the covariance structure of the classification model.We show how to associate to any posterior distribution an effective temperature relating it to the Gibbs prior distribution with the same level of expected error rate, and how to estimate this effective temperature from data, resulting in an estimator whose expected error rate converges according to the best possible power of the sample size adaptively under any margin and parametric complexity assumptions. We describe and study an alternative selection scheme based on relative bounds between estimators, and present a two step localization technique which can handle the selection of a parametric model from a family of those. We show how to extend systematically all the results obtained in the inductive setting to transductive learning, and use this to improve Vapnik's generalization bounds, extending them to the case when the sample is made of independent non-identically distributed pairs of patterns and labels. Finally we review briefly the construction of Support Vector Machines and show how to derive generalization bounds for them, measuring the complexity either through the number of support vectors or through the value of the transductive or inductive margin.

description: Using private funds, the Reel Men Rentals is constructing a new facility on a 1.185-acre parcel located at in Phoenix. The project involves the construction of a building, parking lot, loading docks, and associated infrastructure. The parcel is located at the north of the prehistoric site Las Canopas, AZ T:12:137(ASM). Since this is a village site there is the potential to uncover human remains during construction excavations. Therefore, the project needs to comply with the State burial law, ARS § 41-865, as well as Chapter 8, Section 802[B2] of the City of Phoenix's (COP) Historic Preservation Ordinance. No human remains or archaeological features were discovered; only three chipped stone flakes were found during the monitoring. Following is some background information about the site and the methods used for the monitoring.

subject: FOS: Physical sciences

description: The selfconsistent approach to the 2D Ising Model with quenched random bonds is extended to the full lattice theory of four real fermions. The additional degrees of freedom, neglected in the renormalization-group theory, lead to a new phase between the ferromagnetic and the paramagnetic phase. The disorder averaged spin-spin correlation function decays exponentially with distance. The corresponding correlation length is $1/η^2$, where $η$ denotes the order parameter of the new phase introduced by Ziegler.

description: The nonlinear sigma model for which the field takes its values in the coset space $O(1,2)/O(2)\times Z_2$ is similar to quantum gravity in being perturbatively nonrenormalizable and having a noncompact curved configuration space. It is therefore a good model for testing nonperturbative methods that may be useful in quantum gravity, especially methods based on lattice field theory. In this paper we develop the theoretical framework necessary for recognizing and studying a consistent nonperturbative quantum field theory of the $O(1,2)/O(2)\times Z_2$ model. We describe the action, the geometry of the configuration space, the conserved Noether currents, and the current algebra, and we construct a version of the Ward-Slavnov identity that makes it easy to switch from a given field to a nonlinearly related one. Renormalization of the model is defined via the effective action and via current algebra. The two definitions are shown to be equivalent. In a companion paper we develop a lattice formulation of the theory that is particularly well suited to the sigma model, and we report the results of Monte Carlo simulations of this lattice model. These simulations indicate that as the lattice cutoff is removed the theory becomes that of a pair of massless free fields. Because the geometry and symmetries of these fields differ from those of the original model we conclude that a continuum limit of the $O(1,2)/O(2)\times Z_2$ model which preserves these properties does not exist.

description: There are different assumptions on the substructure of the pentaquarks $P_c(4380)$ and $P_c(4450)$, newly founded in $J/ψN $ invariant mass by the LHCb collaboration, giving consistent mass results with the experimental observations. The experimental data and recent theoretical studies on their mass suggest interpretation of these states as spin-3/2 negative-parity and spin-5/2 positive-parity pentaquarks, respectively. There may exist opposite-parity states corresponding to these particles, as well. Despite a lot of studies, however, the nature and internal organization of these pentaquarks in terms of quarks and gluons are not clear. To this end we need more theoretical investigations on other physical properties of these states. In this accordance, we study a strong and dominant decay of the $P_c(4380)$ to $J/ψ$ and $N$ in the framework of three point QCD sum rule method. An interpolating current in a molecular form is applied to calculate six strong coupling form factors defining the transitions of the positive and negative parity spin-3/2 pentaquark states. The values of the coupling constants are used in the calculation of the decay widths of these transitions. The obtained results are compared with the existing experimental data.

description: In this work, we present a high-throughput first-principles study of elastic properties of bulk and monolayer materials mainly using the vdW-DF-optB88 functional. We discuss the trends on the elastic response with respect to changes in dimensionality. We identify a relation between exfoliation energy and elastic constants for layered materials that can help to guide the search for vdW bonding in materials. We also predicted a few novel materials with auxetic behavior. The uncertainty in structural and elastic properties due to the inclusion of vdW interactions is discussed. We investigated 11,067 bulk and 257 monolayer materials. Lastly, we found that the trends in elastic constants for bulk and their monolayer counterparts can be very different. All the computational results are made publicly available at easy-to-use websites: https://www.ctcms.nist.gov/~knc6/JVASP.html and https://jarvis.nist.gov/ . Our dataset can be used to identify stiff and flexible materials for industrial applications.
Fostering trust in technical services through integrated, collaborative and contextual learning
Creators: name: Mendoza, Gretchen Marie
Publisher: name: Carnegie Mellon University

Subjects: Design

description: Trust is an intrinsic component of any loyal “consumer friendship” between customers and service providers, and is a by-product of shared understanding. Nowhere is the notion of trust more relevant than in technical service—such as professional legal practice, architecture, medical care and auto repair—where the primary commodities exchanged are specialized knowledge, equipment and skills. A common challenge in dialogue between expert providers and novice customers in this context is meaningful sharing of technical information. A successful exchange requires care in representation, language, attitude, delivery and timing. Furthermore, with communication breakdowns, trust falters, and business relationships run the risk of falling apart. Rather than relying on simple transactional exchanges of information in service, a customer’s journey could be enriched by framing service touchpoints as individual opportunities for learning. Learning activities occur in everyday life via interactions with society, artifacts or programs, and often involve the pursuit of knowledge or skills without the structure of a formal curriculum. This study explores how learning might function as a channel for strengthening multi-faceted trust relations in service through integration into programs and artifacts. In this project, an auto repair shop was investigated as a case study in technical service, given its long inglorious history of customer mistrust. Through exploration in the context of a local mechanic shop, prototypes for experiential and transformative service learning were implemented, tested, and re-shaped into a four-part framework designed to improve technical communications
Supervised Descent Method

description: In this dissertation, we focus on solving Nonlinear Least Squares problems using a supervised approach. In particular, we developed a Supervised Descent Method (SDM), performed thorough theoretical analysis, and demonstrated its effectiveness on optimizing analytic functions, and four other real-world applications: Inverse Kinematics, Rigid Tracking, Face Alignment (frontal and multi-view), and 3D Object Pose Estimation. In Rigid Tracking, SDM was able to take advantage of more robust features, such as, HoG and SIFT. Those non-differentiable image features were out of consideration of previous work because they relied on gradient-based methods for optimization. In Inverse Kinematics where we minimize a non-convex function, SDM achieved significantly better convergence than gradient-based approaches. In Face Alignment, SDM achieved state-of-the-arts results. Moreover, it was extremely computationally efficient, which makes it applicable for many mobile applications. In addition, we provided a unified view of several popular methods including SDM on sequential prediction, and reformulated them as a sequence of function compositions. Finally, we suggested some future research directions on SDM and sequential prediction.

description: Single-phase Ni-doped SnO2 with concentrations of 2.5%, 5%, and 7.5% was prepared by the simple co-precipitation method and studied to tailor the optical energy gap and magnetism useful for diluted magnetic semiconductor (DMS) applications. In all compositions, XRD analysis shows Ni doping with no peak shift. Ni doping in SnO2 increases the energy band gap from 3.51 eV to 4.09 eV, reducing optical absorbance. Room-temperature PL emission with excitation at 320 nm produces strong red emissions. Room-temperature magnetic investigations show that 2.5% Ni doping in pure SnO2 changes diamagnetism to soft ferromagnetism with 0.5 emu/g magnetisation and 149 Oe coercivity. More Ni doping reduces magnetisation and leads to paramagnetism, which is attributed to interstitial charge accumulation. The Rietveld analysis of the XRD data reveals a cation deficiency, while the maximum entropy method (MEM) analysis of the electronic structure and bonding behaviour reveals the maximum dilution of Ni2+ ions in the Sn4+ host site at 2.5% doping. Further doping increases interstitial charge accumulation, defects, and magnetisation reduction. MEM also shows a new empirical conclusion: for magnetism to be fully developed, the Ni2+ needs to be diluted correctly in the Sn4+ host lattice so that there is no charge buildup between the atoms (interstitial) and the Sn/Ni-O covalency needs to be maximum in both apical and equatorial directions. In conclusion, a dilute Ni-doped SnO2 system allowed to achieve a soft ferromagnetic transition and optical band tuning.

description: We look for solutions to a fractional Schrödinger equation of the following form $$ (-Δ)^{α/ 2} u + \left( V(x) - \fracμ{|x|^α} \right) u = f(x,u)-K(x)|u|^{q-2}u\hbox{ on }\mathbb{R}^N \setminus \{0\}, $$ where $V$ is bounded and close-to-periodic potential and $- \fracμ{|x|^α}$ is a Hardy-type potential. We assume that $V$ is positive and $f$ has the subcritical growth but not higher than $|u|^{q-2}u$. If $μ$ is positive and small enough we find a ground state solution, i.e. a critical point of the energy being minimizer on the Nehari manifold. If $μ$ is negative we show that there is no ground state solutions. We are also interested in an asymptotic behaviour of solutions as $μ\to 0^+$ and $K \to 0$.

description: Exposing single-walled carbon nanotubes to room temperature UV-generated ozone leads to an irreversible increase in their electrical resistance. We demonstrate that the increased resistance is due to ozone oxidation on the sidewalls of the nanotubes rather than at the end caps. Raman and x-ray photoelectron spectroscopy show an increase in the defect density due to the oxidation of the nanotubes. Using ultraviolet photoelectron spectroscopy we show that these defects represent the removal of pi-conjugated electron states near the Fermi level, leading to the observed increase in electrical resistance. Oxidation of carbon nanotubes is an important first step in many chemical functionalization processes. Since the oxidation rate is controllable with short exposures, UV-generated ozone offers the potential for use as a low-thermal budget processing tool.

description: This IFIT Discussion Paper is authored by Jasmina Brankovic. 

In societies marked by deep social divisions, powerful individuals and organisations play a key role in building up narratives which promote either peaceful engagement or polarisation that can lead to violence. This paper discusses the wide range of actors who have the power to shape narratives at the national level, elaborating them to advance their goals. It proposes practical strategies on how diverse stakeholders—civil society, policy makers and donors, among others—can work with, as well as around, these influential actors to ensure that the narrative landscape advances peace instead of deepening conflict and polarisation.

The paper challenges the view that imposing a new unifying narrative is an effective way to counter polarisation, instead advocating for work that illuminates narrative biases, changes narratives from within and amplifies smaller stories to encourage social engagement at scale. Based on consultations with IFIT brain trusts in Libya, Colombia and Zimbabwe, IFIT’s Inclusive Narratives Practice Group and other leading experts in narrative and politics, it expands on original ideas and recommendations presented in IFIT’s initial narrative framework publication and follow-on discussion paper on media and narrative.
Super-Planckian Thermal Radiation from Nanophotonic Structures:|bTheory, Simulation and Experiment
Creators: name: Baoan  Liu
Publisher: name: Carnegie Mellon University
Year: 2016
Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: Thermal radiation from macroscopic objects is limited by the well-known Planck's law. However, when the sizes of the objects or the gaps between the objects are in the micro- or nano-scale, Planck's law is no longer valid and the radiative power can exceed the blackbody limit by orders of magnitude. This super-Planckian thermal radiation phenomenon has attracted significant attention in the fields of the thermal management, energy conversion, infrared sensing and imaging, etc. Nevertheless, in comparison with the traditional thermal radiation under the framework of Planck's law, the understanding of super-Planckian thermal radiation is still relatively immature in the aspects of theoretical description, numerical modeling, and experimental characterization. In this dissertation, we discover new methodologies to design and manipulate the super- Planckian thermal radiation by using the nanophotonic techniques, such as metamaterial, plasmonics, optical cavity effects, etc. First, we present a broadband near-field thermal emitter based on hyperbolic metamaterials, which can significantly enhance near-field radiative heat ransfer with an infrared surface-polariton resonant materials and maintain the monochromatic characteristic of heat transfer. Second, we discover that the thermal graphene plasmons can be efficiently excited and have monochromatic and tunable spectra by graphene nanoribbons, which are resonant near-field thermal emitters. We further demonstrate that "thermal information communication" via graphene surface plasmons can be potentially realized by effectively harnessing thermal energy from various heat sources. To further understand the super-Planckian thermal radiation of the resonant emitters, we develop a general and self-consistent theory from fluctuational electrodynamics and Quasi-Normal Mode theory to describe the thermal radiation from microscale optical resonators made by lossy and dispersive materials. With our theory, we finally propose a general formalism to make the perfect resonant thermal emitters from the densely packed transmission line resonators, and experimentally demonstrate that the thermal emission from the transmission line resonator arrays can be maximized by tuning the waveguiding mode loss or bending the individual structure. In addition, we implement two numerical simulation methods (the Wiener Chaos Expansion method and the Fluctuating Surface Current method) to directly calculate the super- Planckian thermal radiation of arbitrary geometries. We also propose two highly efficient algorithms to expedite the simulations of periodic and symmetric structures and two-dimensional materials like graphene. These two numerical methods serve as our general computational tools and allow us to investigate the thermal radiation of complex nanophotonic structures in detail.
A catalogue of masses, structural parameters and velocity dispersion profiles of 112 Milky Way globular clusters

description: We have determined masses, stellar mass functions and structural parameters of 112 Milky Way globular clusters by fitting a large set of N-body simulations to their velocity dispersion and surface density profiles. The velocity dispersion profiles were calculated based on a combination of more than 15,000 high-precision radial velocities which we derived from archival ESO/VLT and Keck spectra together with ~20,000 published radial velocities from the literature. Our fits also include the stellar mass functions of the globular clusters, which are available for 47 clusters in our sample, allowing us to self-consistently take the effects of mass segregation and ongoing cluster dissolution into account. We confirm the strong correlation between the global mass functions of globular clusters and their relaxation times recently found by Sollima & Baumgardt (2017). We also find a correlation of the escape velocity from the centre of a globular cluster and the fraction of first generation stars (FG) in the cluster recently derived for 57 globular clusters by Milone et al. (2017), but no correlation between the FG star fraction and the global mass function of a globular cluster. This could indicate that the ability of a globular cluster to keep the wind ejecta from the polluting star(s) is the crucial parameter determining the presence and fraction of second generation stars and not its later dynamical mass loss.

description: The large Hohokam site of Los Aumentos (AZ T:12:178 [ASM]) is located in Phoenix, Arizona. WestLand Resources, Inc. (WestLand), was contracted by AZ 72 LLC and Capri I LLC to conduct archaeological testing. The proposed project (PGM 2006-40) is a mixed residential and commercial development. The project area is located on privately owned land. The City of Phoenix conducted an archaeological assessment of the proposed project (Z-31-06-7) on 18 April 2006 and determined that archaeological monitoring and/or testing would be needed for the portion of the project that appeared to include a small part of Los Aumentos. WestLand Resources, Inc. (WestLand) archaeologists tested within the boundaries of the site and a buffer area at the 1.5 percent level using 34 20-m-long backhoe trenches. No cultural features or deposits were found during archaeological testing. Because no prehistoric or historic cultural features or deposits were found during this testing project, WestLand recommends cultural resource clearance for the tested area. It is also WestLand’s opinion that, because of the absence of cultural remains and the extreme unlikelihood of human burials, archaeological monitoring of construction activities is not warranted.

description: We investigate the phase structure of three-dimensional quantum gravity coupled to an Ising spin system by means of numerical simulations. The quantum gravity part is modelled by the summation over random simplicial manifolds, and the Ising spins are located in the center of the tetrahedra, which constitute the building blocks of the piecewise linear manifold. We find that the coupling between spin and geometry is weak away from the critical point of the Ising model. At the critical point there is clear coupling, which however does not seem to change the first order transition between the ``hot'' and ``cold'' phase of three dimensional simplicial quantum gravity observed earlier.

description: We introduce a class of recursions defined over the $d$-dimensional integer lattice. The discrete equations we study are interpreted as higher dimensional extensions to the discrete Toda lattice equation. We shall prove that the equations satisfy the coprimeness property, which is one of integrability detectors analogous to the singularity confinement test. While the degree of their iterates grows exponentially, their singularities exhibit a nature similar to that of integrable systems in terms of the coprimeness property. We also prove that the equations can be expressed as mutations of a seed in the sense of the Laurent phenomenon algebra.

description: Artistic painting involves mastery of haptic interaction with tools. Each tool brings unique physical affordances which determines an aesthetic expression of the finished work. For instance, a pen offers an ability to make a precise stroke in a realism painting, whereas a thick brush or a sponge works perfectly with dynamic arm movement in the abstract art such as action painting. Yet the selection of a tool is just a beginning. It requires repetitive training to understand the full capability of the tool affordance and to master the painting of preferred aesthetic strokes. Such physical act of an artistic expression cannot be captured by the computational tools today. Due to the increasing market adoption of augmented reality and virtual reality, and the decades of studies in haptics, we see an opportunity for advancing 3D painting experiences in non-conventional approach. In this research, we focus on force haptic interaction for 3D painting art in a room-scale virtual reality. We explore virtual tangibility and tool affordance of its own medium. In addition to investigating the fidelity of a physical interactivity, we seek ways to extend the painting capabilities by computationally customized force feedback and metaphor design. This system consists of a wearable force feedback device that sits on user’s hand, a software for motor control and real-time 3D stroke generation, and their integration to VR platform. We work closely with an artist to refine the 3D painting application and to evaluate the system’s usability.

description: We use relations between the base change representations and theta lifts, to give a new proof to the local period problems of SL(2) over a nonarchimedean quadratic field extension E/F.

Shear-density coupling for a compressible single-component yield-stress fluid

description: Flow behavior of a single-component yield stress fluid is addressed on the hydrodynamic level. A basic ingredient of the model is a coupling between fluctuations of density and velocity gradient via a Herschel-Bulkley-type constitutive model. Focusing on the limit of low shear rates and high densities, the model approximates well---but is not limited to---gently sheared hard sphere colloidal glasses, where solvent effects are negligible. A detailed analysis of the linearized hydrodynamic equations for fluctuations and the resulting cubic dispersion relation reveals the existence of a range of densities and shear rates with growing flow heterogeneity. In this regime, after an initial transient, the velocity and density fields monotonically reach a spatially inhomogeneous stationary profile, where regions of high shear rate and low density coexist with regions of low shear rate and high density. The steady state is thus maintained by a competition between shear-induced enhancement of density inhomogeneities and relaxation via overdamped sound waves. An analysis of the mechanical equilibrium condition provides a criterion for the existence of steady state solutions. The dynamical evolution of the system is discussed in detail for various boundary conditions, imposing either a constant velocity, shear rate, or stress at the walls.

Sulfur Poisoning of Pd and PdCu Alloy Hydrogen Separation Membranes

description: Separation of high purity H2 from coal-derived syngas is a key unit process in next generation gasification processes. Dense Pd and Pd47Cu53 (mol%) alloy membranes are promising candidates for separating H2 from mixed gases due to their rare combination of high permeability and high selectivity to H2 separation. However, ppm concentrations of H2S, a coal gasification byproduct, can severely inhibit hydrogen transport across Pd and Pd47Cu53 membranes in the temperature range that the membrane would need to be operated in a gasification process (~500 to ~700 K). This thesis is an experimental investigation of hydrogen transport (H2 dissociation and H atom permeation) across Pd and Pd47Cu53 alloy membranes. The objective of this thesis was to understand how H2S inhibits hydrogen transport across Pd and Pd47Cu53 alloy membranes. H2S slows hydrogen transport across Pd membranes mainly by producing a Pd4S film on the surface of the Pd membrane that is about an order-of-magnitude less permeable to hydrogen than Pd. In contrast to Pd, the Pd47Cu53 alloy is resistant to bulk sulfidation; H2S slows hydrogen transport across Pd47Cu53 by decreasing the rate of H2 dissociation on the Pd47Cu53 surface. H2S also decreases the rate of H2 dissociation on the Pd4S surface, but not as significantly as that on the Pd47Cu53 surface At high temperatures (~900 K), the rate of hydrogen permeation through the Pd47Cu53 alloy is not significantly affected by 1000 ppm H2S. It is likely that the sulfur tolerance exhibited by the Pd47Cu53 alloy at high temperatures is due to its resistance to bulk sulfidation. However, our results indicate that the Pd47Cu53 alloy is not thermodynamically resistant to sulfidation. Thin metal (Fe, Ni, Co, Cr, Mo, Pt) films on the surface of the Pd47Cu53 alloy catalyzed its corrosion to Pd13Cu3S7 and Cu2S during exposure to H2S, which suggests that sulfidation of Pd47Cu53 is kinetically limited by a surface reaction. This result is important because understanding why Pd47Cu53 alloy membranes are resistant to sulfidation may lead to the development of membrane materials that can tolerate the harsh conditions of coal gasification processes.

description: We present atmospheric gas entropy profiles for 40 early type galaxies and 110 clusters spanning several decades of halo mass, atmospheric gas mass, radio jet power, and galaxy type. We show that within $\sim 0.1R_{2500}$ the entropy profiles of low-mass systems, including ellipticals, brightest cluster galaxies, and spiral galaxies, scale approximately as $K\propto R^{2/3}$. Beyond $\sim 0.1R_{2500}$ entropy profiles are slightly shallower than the $K \propto R^{1.1}$ profile expected from gravitational collapse alone, indicating that heating by AGN feedback extends well beyond the central galaxy. We show that the $K\propto R^{2/3}$ entropy profile shape indicates that thermally unstable cooling is balanced by heating where the inner cooling and free-fall timescales approach a constant ratio. Hot atmospheres of elliptical galaxies have a higher rate of heating per gas particle compared to central cluster galaxies. This excess heating may explain why some central cluster galaxies are forming stars while most early-type galaxies have experienced no significant star formation for billions of years. We show that the entropy profiles of six lenticular and spiral galaxies follow the $R^{2/3}$ form. The continuity between central galaxies in clusters, giant ellipticals, and spirals suggests perhaps that processes heating the atmospheres of elliptical and brightest cluster galaxies are also active in spiral galaxies.

description: We study the behavior of the isovector scalar correlator, which is particularly sensitive to lattice artifacts, using domain-wall valence quarks on a staggered sea (generated by the MILC collaboration). We analyze this according to the prediction from chiral perturbation theory determined by Prelovsek, which indicates that the leading unitarity violations come from taste breaking effects. We show that our data behaves in the way predicted by Prelovsek, thus verifying that the largest contribution to the violations of unitarity which arise at finite lattice spacing can be described by the mixed-action chiral perturbation theory.

description: We study the topological optical states in one-dimensional (1D) dimerized ultracold atomic chains, as an extension of the Su-Schrieffer-Heeger (SSH) model. By taking the fully retarded near-field and far-field dipole-dipole interactions into account, we describe the system by an effective non-Hermitian Hamiltonian, vastly different from the Hermitian Hamiltonian of the conventional SSH model. We analytically calculate the complex bandstructures for infinitely long chains, and show that the topological invariant, i.e., the complex Zak phase, is still quantized and becomes nontrivial when the dimerization parameter $β>0.5$, despite the broken chiral symmetry and non-Hermiticity. We have verified the validity of the bulk-boundary correspondence for this non-Hermitian system by further analyzing the eigenstate distributions along with their inverse participation ratios (IPRs) for finite chains, where topologically protected edge states are unambiguously identified. We also reveal that such topological edge states are robust under symmetry-breaking disorders. For transverse eigenstates, we further discover the increase of localization length of topological edge states with the increase of lattice period due to the presence of strong far-field dipole-dipole interactions. Moreover, the ultra-strong scattering cross section and ultra-narrow linewidth of a single cold atom allow us to observe in more detail about topological states than in conventional systems, such as the frequency shift with respect to the single-atom resonance and the largely tunable bandgap. We envisage these topological photonic states can provide an efficient interface between light and matter.
