description: We present the Robert C. Byrd Green Bank Telescope discovery of the highly eccentric binary millisecond pulsar PSR J1835$-$3259A in the Fermi Large Area Telescope-detected globular cluster NGC 6652. Timing over one orbit yields the pulse period 3.89 ms, orbital period 9.25 d, eccentricity $\sim 0.95$, and an unusually high companion mass of $0.74\,M_{\odot}$ assuming a $1.4\,M_{\odot}$ pulsar. We caution that the lack of data near periastron prevents a precise measurement of the eccentricity, and that further timing is necessary to constrain this and the other orbital parameters. From tidal considerations, we find that the companion must be a compact object. This system likely formed through an exchange encounter in the dense cluster environment. Our initial timing results predict the measurements of at least two post-Keplerian parameters with long-term phase-connected timing: the rate of periastron advance $\dotω \sim 0.1^{\circ}\,$yr$^{-1}$, requiring 1 yr of phase connection; and the Einstein delay $γ_{\mathrm{GR}} \sim 10\,$ms, requiring 2-3 yr of timing. For an orbital inclination $i > 50^{\circ}$, a measurement of $\sin{i}$ is also likely. PSR J1835$-$3259A thus provides an opportunity to measure the neutron star mass with high precision; to probe the cluster environment; and, depending on the nature of the companion, to investigate the limits of general relativity.

description: Gyroscope for rotation sensing plays a key role in inertial navigation systems. Developing more precise gyroscopes than the conventional ones bounded by classical shot-noise limit by using quantum resources has attracted much attention. However, existing quantum gyroscope schemes suffer severe deterioration under the influence of decoherence, which is called the no-go theorem of noisy metrology. Here, by using two quantized optical fields as quantum probe, we propose a quantum gyroscope scheme breaking through the constraint of the no-go theorem. Our exact analysis of the non-Markovian noise reveals that both the evolution time as a resource in enhancing the sensitivity and the achieved super-Heisenberg limit in the noiseless case are asymptotically recoverable when each optical field forms a bound state with its environment. The result provides a guideline for realizing high-precision rotation sensing in realistic noisy environments.

description: We compute the $N=2$ Rényi entanglement entropy of two intervals at equal time in a circle, for the theory of a 2d compact complex free scalar at finite temperature. This is carried out by performing functional integral on a genus 3 ramified cover of the torus, wherein the quantum part of the integral is captured by the four point function of twist fields on the worldsheet torus, and the classical piece is given by summing over winding modes of the genus 3 surface onto the target space torus. The final result is given in terms of a product of theta function and certain multi-dimensional theta function. We demonstrate the T-duality invariance of the result. We also study its low temperature limit. In the case in which the size of the intervals and of their separation are much smaller than the whole system, our result is in exact agreement with the known result for two intervals on an infinite system at zero temperature \cite{eeoftwo}. In the case in which the separation between the two intervals is much smaller than the interval length, the leading thermal corrections take the same universal form as proposed in \cite{Cardy:2014jwa,Chen:2015cna} for Rényi entanglement entropy of a single interval.

description: X-ray luminosity functions (XLFs) of Active Galactic Nuclei (AGN) trace the growth and evolution of supermassive black hole populations across cosmic time, however, current XLF models are poorly constrained at redshifts of z>6, with a lack of spectroscopic constraints at these high redshifts. In this work we \redit{place limits} on the bright-end of the XLF at z=5.7-6.4 using high-redshift AGN identified within the Extragalactic Serendipitous Swift Survey (ExSeSS) catalogue. Within ExSeSS we find one serendipitously X-ray detected z>6 AGN, ATLAS J025.6821-33.4627, with an X-ray luminosity of $L_\mathrm{X}=8.47^{+3.40}_{-3.13}\times10^{44}\mathrm{erg.s^{-1}}$ and $z=6.31\pm0.03$ making it the highest redshift, spectroscopically confirmed, serendipitously X-ray detected quasar known to date. We also calculate an upper limit on the space density at higher luminosities where no additional sources are found, enabling us to place constraints on the shape of the XLF. Our results are consistent with the rapid decline in the space densities of high-luminosity AGN toward high redshift as predicted by extrapolations of existing parametric models of the XLF. We also find that our X-ray based measurements are consistent with estimates of the bolometric quasar luminosity function based on UV measurements at $z\gtrsim6$, although they require a large X-ray to bolometric correction factor at these high luminosities.

description: We study the plasma branch of an homogeneous three-dimensional electron gas in an $s$-wave superconducting state. We focus on the regime where the plasma frequency $ω_p$ is comparable to the gap $Δ$, which is experimentally realized in cuprates. Although a sum rule guarantees that the departure of the plasma branch always coincides with the plasma frequency, the dispersion and lifetime of the plasmons is strongly affected by the presence of the pair condensate, especially at energies close to the pair-breaking threshold $2Δ$. When $ω_p $ is above $1.7Δ$, the level repulsion is strong enough to give the plasma branch an anomalous, negative dispersion with a minimum at finite wavelength. At non-zero temperature and at $ω_p>2Δ$, we treat in a non-perturbative way the coupling of plasmons to the fermionic excitations, and show that a broadened plasma resonance inside the pair-breaking continuum coexists with an undamped solution in the band gap. This resonance splitting is associated with the presence of multiple poles in the analytic continuation of the propagator of the Cooper pairs.

Systematic Review of Nosocomial Waterborne Infections caused by Nontuberculous Mycobacteria
Creators: name: Li, Trudy
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Background: Healthcare-acquired infections are an increasing priority for health care providers and policy makers. Water is an overlooked source of infectious microorganisms in health care facilities. Waterborne nontuberculous mycobacteria (NTM) are ubiquitous, especially in health care facility water systems, and are known to result in a variety of clinical diseases. Purpose: To contribute to an understanding of prevalence and disease burden, we conducted a systematic review to assess health care associated NTM infections from health care facility water systems. We document susceptible populations, modes of transmission, and the median attack rate. We aim to identify transmission risk factors and inform evidence-based policies for infection control and prevention. Methods: We searched Embase, Pubmed, Web of Science and clinicaltrials.gov without date restrictions. English language articles with original data on NTM waterborne infections in health care settings were included. Study Selection & Data Extraction: Randomized controlled trials, descriptive studies (case reports, case series), case-control studies, cohort studies, cross-sectional surveys, and quasiexperimental studies on nosocomial waterborne infections were included. Three investigators independently screened titles and abstracts for relevant articles, and one screened full-text articles. Data was extracted by one investigator, and a second confirmed accuracy for 10% of results. Results: We included 22 observational studies. Immunocompromised, post-surgical, and hemodialysis patients were commonly affected populations, and a range of exposure routes such as uncovered central venous catheters (CVCs), wound exposure, and contamination during surgical procedures was reported. The median attack rate was 12.1% (interquartile range, 11- 27.2). Conclusion: Waterborne NTM infection affects susceptible patients through common, preventable exposure routes. Effective prevention strategies will require both medical and environmental health expertise, and inter-professional cooperation will optimize these efforts. Additional high-quality studies using genotypic methods are also needed, especially in low- and middle-income countries.

The algorithm cleverly combines key ideas borrowed from forward decay, the Count-Min and the Space Saving algorithms. It works in the time fading model, mining data streams according to the cash register model. We formally prove its correctness and show, through extensive experimental results, that our algorithm outperforms $λ$-HCount, a recently developed algorithm, with regard to speed, space used, precision attained and error committed on both synthetic and real datasets.

The purpose of this note is to provide a simplified self-contained probabilistic proof of EHI in ${\mathbb{Z}}^d$ that is accessible at the undergraduate level. We use the Local Central Limit Theorem for simple symmetric random walks on ${\mathbb{Z}}^d$ to establish Gaussian bounds for the $n$-step probability function. The uniform Green inequality and the classical Balayage formula then imply the EHI.

description: Analog-to-digital converters (ADCs) allow physical signals to be processed using digital hardware. Their conversion consists of two stages: Sampling, which maps a continuous-time signal into discrete-time, and quantization, i.e., representing the continuous-amplitude quantities using a finite number of bits. ADCs typically implement generic uniform conversion mappings that are ignorant of the task for which the signal is acquired, and can be costly when operating in high rates and fine resolutions. In this work we design task-oriented ADCs which learn from data how to map an analog signal into a digital representation such that the system task can be efficiently carried out. We propose a model for sampling and quantization that facilitates the learning of non-uniform mappings from data. Based on this learnable ADC mapping, we present a mechanism for optimizing a hybrid acquisition system comprised of analog combining, tunable ADCs with fixed rates, and digital processing, by jointly learning its components end-to-end. Then, we show how one can exploit the representation of hybrid acquisition systems as deep network to optimize the sampling rate and quantization rate given the task by utilizing Bayesian meta-learning techniques. We evaluate the proposed deep task-based ADC in two case studies: the first considers symbol detection in multi-antenna digital receivers, where multiple analog signals are simultaneously acquired in order to recover a set of discrete information symbols. The second application is the beamforming of analog channel data acquired in ultrasound imaging. Our numerical results demonstrate that the proposed approach achieves performance which is comparable to operating with high sampling rates and fine resolution quantization, while operating with reduced overall bit rate.

description: A rapid, precise, accurate, and cost-effective liquid chromatography-mass spectrometer method was developed by using a novel extraction technique for the simultaneous quantification of major oleane derivatives: arjunetin, arjungenin, arjunolic acid, and arjunic acid of Terminalia arjuna in infused edible oil. An innovative idea was implemented to extract the active phytoconstituents from the oil matrix based on the freezing point of oils and extraction solvent. The developed method was validated for all four active compounds in the linear working range of 0.47–1.72 µg/mL, 0.845–2.93 µg/mL, 1.73–5.95 µg/mL and 0.62–2.22 µg/mL with good correlations value (r2) more than 0.99 for arjunetin, arjungenin, arjunolic acid, and arjunetin, respectively. Furthermore, the HPTLC method was also developed for the quick identification of all four active markers along with other phytoconstituents infused in oil.

Policy Considerations for the Development and Integration of Community Health Workers in North Carolina
Creators: name: Jewell, Celia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Community Health Workers (CHWs) are trained to address health needs within communities that have poor health outcomes due to cultural and language barriers and low socioeconomic status. The effectiveness of CHWs is attributed to their trusted relationship with the community, ability to speak the same language and present health information and services in a culturally sensitive manner. Many states are developing CHW programs through policies that build CHW infrastructure, professional identity, workforce development and financing of programs in order to decrease health care costs, improve health status, improve health care delivery and decrease health disparities among underserved, vulnerable populations. A logic model describes how the inputs of comprehensive CHW policies construct a pathway through which CHW activities are generated and the long-term outcomes of decreased health care costs, improved health status, improved health care delivery and decreased health disparities among target populations can be achieved. The logic model is used to evaluate the effectiveness of CHW interventions in two states, Massachusetts and Texas, which have developed comprehensive CHW policies. Although it is not possible to establish a direct causal link between the comprehensive policies and intended outcomes due to limited research, the evidence from the available studies conducted in Massachusetts and Texas suggest that policies that support CHW activities do promote the desired outcomes. Based on the evaluation, recommendations are presented for the development of a sustainable CHW program within the North Carolina public health and health care systems.

description: Metaverse, with the combination of the prefix "meta" (meaning transcending) and the word "universe", has been deemed as the next-generation (NextG) Internet. It aims to create a shared virtual space that connects all virtual worlds via the Internet, where users, represented as digital avatars, can communicate and collaborate as if they are in the physical world. Nevertheless, there is still no unified definition of the Metaverse. This article first presents our vision of what the key requirements of Metaverse should be and reviews what has been heavily advocated by the industry and the positions of various high-tech companies. It then briefly introduces existing social virtual reality (VR) platforms that can be viewed as early prototypes of Metaverse and conducts a reality check by diving into the network operation and performance of two representative platforms, Workrooms from Meta and AltspaceVR from Microsoft. Finally, it concludes by discussing several opportunities and future directions for further innovation.

description: Die Debatten des new materialism werfen erkenntnistheoretische und ethische Fragen auf. Von der Annahme ausgehend, dass diese neomaterialistische Kritik anthropozentrischer Prämissen eine wichtige Irritation gesellschaftstheoretischer Wissensproduktion ist, geht der Text der Frage nach, inwiefern Karen Barads Arbeiten Ansatzpunkte bieten, an denen gesellschaftstheoretische und kritische Wissensproduktion produktiv hinterfragt werden kann. Es geht dabei nicht darum diese damit zu verwerfen, sondern sie umzuarbeiten, um an ihrem (rekonfigurierten) emanzipatorischen Potenzial festhalten zu können. Insbesondere die spezifische historische Figur des autonomen Subjekts und die mit ihr einhergehende Subjekt-Objekt-Dichotomie werden dabei als Teil des Problems und nicht Ausgangspunkt erhoffter Lösungen erkennbar. Die Schwierigkeit, dass die Kritik des Anthropozentrismus letztlich als Praxis eines ganz spezifischen menschlichen Subjekts und somit in gewisser Weise eine Paradoxie ist, soll mit Gayatri Spivaks Begriff des double bind aufgegriffen und als praktische Erfahrung im Erkenntnisprozess verfügbar gemacht werden.

Our receiver architecture forgoes the need for any polarization matching calibrations or feedback loops and is usable in any locally generated local oscillator key distribution system.

description: Physical parameters of both the mass donor and compact object can be constrained in X-ray binaries with well-defined eclipses, as our survey of wind-fed supergiant X-ray binaries (SGXBs) IGR J16393-4643, IGR J16418-4532, IGR J16479-4514, IGR J18027-2016 and XTE J1855-026 reveals. Using the orbital period and Kepler's third law, we express the eclipse half-angle in terms of radius, inclination angle and the sum of the masses. Pulse-timing and radial velocity curves can give masses of both the donor and compact object as in the case of the "double-lined" binaries IGR J18027-2016 and XTE J1855-026. The eclipse half angles are 15 (+3,-2), 31.7 (+0.7,-0.8), 32 +/- 2, 34 +/- 2 and 33.6 +/- 0.7 degrees for IGR J16393-4643, IGR J16418-4532, IGR J16479-4514, IGR J18027-2016 and XTE 1855-026, respectively. In wind-fed systems, the primary not exceeding the Roche-lobe size provides an upper limit on system parameters. In IGR J16393-4643, spectral types of B0 V or B0-5 III are found to be consistent with the eclipse duration and Roche-lobe, but the previously proposed donor stars in IGR J16418-4532 and IGR J16479-4514 were found to be inconsistent with the Roche-lobe size. Stars with spectral types O7.5 I and earlier are possible. For IGR J18027-2016, the mass and radius of the donor star lie between 18.6--19.4 $M_\odot$ and 17.4--19.5 $R_\odot$. We constrain the neutron star mass between 1.37--1.43 $M_\odot$. We find the mass and radius of the donor star in XTE J1855-026 to lie between 19.6--20.2 $M_\odot$ and 21.5--23.0 $R_\odot$. The neutron star mass was constrained to 1.77--1.82 $M_\odot$. Eclipse profiles are asymmetric in IGR J18027-2016 and XTE J1855-026, which we attribute to accretion wakes.

description: The exact renormalization group (ERG) is formulated implementing the decimation of degrees of freedom by means of a particular momentum integration measure. The definition of this measure involves a distribution that links this decimation process with the dimensional regularization technique employed in field theory calculations. Taking the dimension d=4-ε, the one loop solutions to the ERG equations for the scalar field theory in this scheme are shown to coincide with the dimensionally regularized perturbative field theory calculation in the limit μ\to0, if a particular relation between the scale parameter μand εis employed. In general, it is shown that in this scheme the solutions to the ERG equations for the proper functions coincide when μ\to0 with the complete diagrammatic contributions appearing in field theory for these functions and this theory, provided that exact relations between μand εhold. In addition a non-perturbative approximation is considered. This approximation consists in a truncation of the ERG equations, which by means of a low momentum expansion leads to reasonable results.

description: In der Theaterwissenschaft wird dem Körper besondere Bedeutung zugeschrieben – über die physische Anwesenheit von Schauspieler*- und Zuschauer*innenkörpern definiert sich die für das Theater konstitutive Dimension der ‚Liveness’ des Geschehens. Körper, Laute, Objekte etc. auf der Bühne werden als temporäre Ergebnisse vielfältiger Materialisierungs- und Verkörperungsprozesse aufgefasst. Unser Beitrag stellt das Verhältnis von Körperlichkeit, Materialität und Gender in Theater und Theaterwissenschaft ins Zentrum der Auseinandersetzung und zielt darauf, die Interdependenz der drei Kategorien herauszuarbeiten und hervorzuheben. Dieser Zusammenhang der drei Begriffe ist in der Theaterwissenschaft durchaus keine Selbstverständlichkeit, im Gegenteil: Während Materialität und Körperlichkeit im Kontext des performative turn eine starke Aufwertung und Zuwendung erfahren haben, ist Gender vergleichsweise marginal geblieben. Im ersten Teil des Artikels soll es um eine begriffstheoretische Erörterung der Kategorien von Materialität und Körperlichkeit in ihrem Verhältnis zur Kategorie Gender gehen, wie sie primär im deutschsprachigen theaterwissenschaftlichen Diskurs der letzten zehn bis 15 Jahre Verwendung finden. Im zweiten Teil stehen drei Strategien des Gegenwartstheaters im Mittelpunkt, welche das Verhältnis von Materialität, Körperlichkeit und Gender verhandeln: Cross-Dressing, Nacktheit und Affektion der Dinge.
A Vaidya-type spacetime with no singularities

description: A regular Vaidya-type line-element is proposed in this work. The mass function depends both on the temporal and the spatial coordinates. The curvature invariants and the source stress tensor $T^{a}_{~b}$ are finite in the whole space. The energy conditions for $T^{a}_{~b}$ are satisfied if $k^{2}<2vr$, where $k$ is a positive constant and $v,r$ are coordinates. It is found that the radial pressure has a maximum very close to $r = 2m~ (r>2m), v = 2m$. The energy crossing a sphere of constant radius is akin to Lundgren-Schmekel-York quasilocal energy. The Newtonian acceleration of the timelike geodesics has an extra term (compared to the result of Piesnack and Kassner) which leads to rejecting effects.

description: The stochastic nature of public transport systems leads to headway variability and bus bunching, causing both operator and passenger cost to increase significantly. Traditional strategies to counter bus bunching, including bus-holding, stop-skipping, and bus substitution/insertion, suffer from trade-offs and shortcomings. Autonomous modular vehicle (AMV) technology provides an additional level of flexibility in bus dispatching and operations, which can offer significant benefits in mitigating bus bunching compared to strategies available with conventional buses. This paper introduces a novel alternative to stop-skipping by leveraging the new capabilities offered by AMVs (in particular, en-route coupling and decoupling of modular units). We develop a simple bus-splitting strategy that directs a modular bus to decouple into individual units when it experiences a headway longer than a given threshold. We then use a macroscopic simulation to present a proof-of-concept evaluation of the proposed modular strategy compared to a benchmark traditional stop-skipping strategy and the base (no control) case. We find that the proposed strategy outperforms the benchmark in decreasing each of the three travel time components: waiting time, in-vehicle time, and walking time (which it eliminates completely). It therefore reduces the overhead of bus bunching and thus the travel cost by more than twice as much as the benchmark for busy bus lines. Simultaneously, it also reduces headway variability to a comparable degree. Furthermore, we analyze different control thresholds for applying the proposed strategy, and show that it is most effective when applied proactively, i.e. with the control action being triggered even by small headway deviations.

EXAMINING THE TOBACCO EPIDEMIC IN ADOLESCENT FEMALES
Creators: name: Ryan, Sheila

description: Introduction: Tobacco use is the leading cause of preventable disease worldwide. Although smoking has declined in some developed countries, the global burden of tobacco-related mortality is shifting to vulnerable populations in low- and middle-income countries. Tobacco use among adolescent females in this population is becoming a growing concern. A systematic review of the literature was undertaken to assess public health programs that aim to address the issue of tobacco use in adolescent females at the community level in low- and middle-income countries. Methodology: A systematic review of the literature from 2010 to February 2014 was undertaken to determine how many studies and what types of studies have been published that focus on community level interventions in female adolescents in four countries representative of the current tobacco epidemic: Turkey, India, Korea, and Argentina. The search was limited to Pubmed, Web of Science, and Global Health online databases. Studies adhered to strict eligibility criteria to eliminate studies not pertinent to adolescent female tobacco use. Studies were stratified into tiers based on the type of study discussed. Further examination of the studies revealed the aspect and determinant of the tobacco epidemic addressed in each study. Results: Twenty-seven studies were included in the systematic review after undergoing qualitative analysis based on eligibility and search criteria. Of these 27 studies, 22 were descriptive studies. The most common strategy addressed was monitoring tobacco use and prevention strategies, including determining prevalence rates in relation to the presence of other factors. Conclusion: This systematic literature review indicated there are limited studies on current community level interventions. From this, a conclusion can be made that more studies of all types are needed to effectively address the issue of tobacco use in adolescent females in low- and middle-income countries. In addition, more articles documenting interventions at the community level need to be published to provide adequate literature on this issue to guide future public health programs.

3d $\mathcal{N}=2$ SO/USp adjoint SQCD: s-confinement and exact identites
Creators: name: Amariti, Antonio

Year: 2022
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study 3d $\mathcal{N}=2$ SQCD with symplectic and orthogonal gauge groups and adjoint matter. For $USp(2n)$ with two fundamentals and $SO(N)$ with one vector these models have been recently shown to s-confine. Here we corroborate the validity of this proposal by relating it to the confinement of $USp(2n)$ with four fundamentals and an antisymmetric tensor, using exact mathematical results coming from the analysis of the partition function on the squashed three-sphere. Our analysis allows us to conjecture new s-confining theories for a higher number of fundamentals and vectors, in presence of linear monopole superpotentials. We then prove the new dualities through a chain of adjoint deconfinements and s-confining dualities.

description: The detection of Earth-size exoplanets is a technological and data analysis challenge. Future progress in Earth-mass exoplanet detection is expected from the development of extreme precision radial velocity measurements. Increasing radial velocity precision requires developing a new physics-based data analysis methodology to discriminate planetary signals from host-star-related effects, taking stellar variability and instrumental uncertainties into account. In this work, we investigate and quantify stellar disturbances of the planet-hosting solar-type star HD121504 from 3D radiative modeling obtained with the StellarBox code. The model has been used for determining statistical properties of the turbulent plasma and obtaining synthetic spectroscopic observations for several Fe I lines at different locations on the stellar disk to mimic high-resolution spectroscopic observations.

description: Quantum cryptography holds the promise to establish an information-theoretically secure global network. All field tests of metropolitan-scale quantum networks to date are based on trusted relays. The security critically relies on the accountability of the trusted relays, which will break down if the relay is dishonest or compromised. Here, we construct a measurement-device-independent quantum key distribution (MDIQKD) network in a star topology over a 200 square kilometers metropolitan area, which is secure against untrustful relays and against all detection attacks. In the field test, our system continuously runs through one week with a secure key rate ten times larger than previous result. Our results demonstrate that the MDIQKD network, combining the best of both worlds --- security and practicality, constitutes an appealing solution to secure metropolitan communications.

description: We consider the potentially degenerate haptotaxis system \begin{equation*} \left\{ \begin{aligned} u_t &= \nabla \cdot (\mathbb{D} \nabla u + u \nabla \cdot \mathbb{D}) - χ\nabla \cdot (u\mathbb{D}\nabla w) + μu(1-u^{r- 1}), \\ w_t &= - uw \end{aligned} \right. \end{equation*} in a smooth bounded domain $Ω\subseteq \mathbb{R}^n$, $n \in \{2,3\}$, with a no-flux boundary condition, positive initial data $u_0$, $w_0$ and parameters $χ> 0$, $μ> 0$, $r \geq 2$ and $\mathbb{D}: \overlineΩ \rightarrow \mathbb{R}^{n\times n}$, $\mathbb{D}$ positive semidefinite on $\overlineΩ$. Our main result regarding the above system is the construction of weak solutions under fairly mild assumptions on $\mathbb{D}$ as well as the initial data, encompassing scenarios of degenerate diffusion in the first equation. As a step in this construction as well as a result of potential independent interest, we further construct classical solutions for the same system under a global positivity assumption for $\mathbb{D}$, which ensures the full regularizing influence of its associated diffusion operator. In both constructions, we naturally rely on the regularizing properties of a sufficiently strong logistic source term in the first equation.

description: We study the resonance interaction between two uniformly accelerated identical atoms, one excited and the other in the ground state, prepared in a correlated (symmetric or antisymmetric) state and interacting with the scalar field or the electromagnetic field in the vacuum state. In this case (resonance interaction), the interatomic interaction is a second-order effect in the atom-field coupling. We separate the contributions of vacuum fluctuations and radiation reaction to the resonance energy shift of the system, and show that only radiation reaction contributes, while Unruh thermal fluctuations do not affect the resonance interaction. We also find that beyond a characteristic length scale related to the atomic acceleration, non-thermal effects in the radiation reaction contribution change the distance-dependence of the resonance interaction. Finally, we find that previously unidentified features appear, compared with the scalar field case, when the interaction with the electromagnetic field is considered, as a consequence of the peculiar nature of the vacuum quantum noise of the electromagnetic field in a relativistically accelerated background.
