description: We formulate the generalized tunneling model for two level systems in insulators that takes into account the interaction between them and a slow power law dependence of their density of states. We show that the predictions of this model are in a perfect agreement with the recent studies of the noise in high quality superconducting resonators. The predictions also agree with the temperature dependence of the TLS dephasing rates observed in phase qubits. Both observations are impossible to explain in the framework of the standard tunneling model of TLS. We discuss the origin of the universal dimensionless parameter that controls the interaction between TLS in glasses and show that it is consistent with the assumptions of the model.

description: Introdução: O Aleitamento Materno (AM) é um ato definido como uma estratégia natural de proteção e nutrição para a criança, bem como é considerada uma intervenção para a redução da morbimortalidade infantil eficaz e econômica (BRASIL, 2015; FERREIRA et al., 2018).c Ademais, proporciona diversos benefícios que transcendem o binômio mãe-filho, sendo eles fisiológicos, emocionais e sociais, cabendo ressaltar que o início precoce da amamentação aumenta a chance de o bebê consumir colostro, que é altamente nutritivo e rico imunologicamente (BRASIL, 2021; LUCCHESE et al., 2021; SILVA et al., 2019; TERRA et al., 2020). Justificativa: Tendo em vista os benefícios apresentados do aleitamento materno na primeira hora de vida e o fato de que apenas 48% das crianças nascidas vivas são amamentadas em sua primeira hora de vida (OPAS, 2021) faz-se relevante buscar as evidências científicas dos últimos dez anos sobre esse tema. Objetivo: Analisar as evidências disponíveis na literatura sobre a Assistência de Enfermagem na Amamentação na Primeira Hora de Vida. Método: Trata-se de uma Revisão Integrativa, com definição da questão norteadora mediante estratégia PICO, sendo ela: “Quais são as evidências científicas da assistência de enfermagem no aleitamento materno na primeira hora de vida?"., e para coleta de dados serão utilizadas as seguintes Bases de Dados: LILACS, CUIDEN, PUBMED e CINAHL.

description: We analyze two approaches to the quantum-classical Liouville (QCL) formalism that differ in the order of two operations: Wigner transformation and projection onto adiabatic electronic states. The analysis is carried out on a two-dimensional linear vibronic model where geometric phase (GP) effects arising from a conical intersection profoundly affect nuclear dynamics. We find that the Wigner-then-Adiabatic (WA) QCL approach captures GP effects, whereas the Adiabatic-then-Wigner (AW) QCL approach does not. Moreover, the Wigner transform in AW-QCL leads to an ill-defined Fourier transform of double-valued functions. The double-valued character of these functions stems from the nontrivial GP of adiabatic electronic states in the presence of a conical intersection. In contrast, WA-QCL avoids this issue by starting with the Wigner transform of single-valued quantities of the full problem. Since the WA-QCL approach uses solely the adiabatic potentials and non-adiabatic derivative couplings as an input, our results indicate that WA-QCL can capture GP effects in general two-state crossing problems using first-principles electronic structure calculations without prior diabatization or introduction of explicit phase factors.

description: Considering the action for the theory $λϕ^{4}$ for a massive scalar bosonic field as an entropy functional on the space of coupling constants and on the space of fields, we determine the gradient flows for the scalar field, the mass, and the self-interaction parameter. When the flow parameter is identified with the energy scale, we show that there exist phase transitions between unbroken exact symmetry scenarios and spontaneous symmetry breaking scenarios at increasingly high energies. Since a non-linear heat equation drives the scalar field through a {\it reaction-diffusion} process, in general the flows are not reversible, mimicking the renormalization group flows of the $c$-theorem; the deformation of the field at increasingly high energies can be described as non-linear traveling waves, or solitons associated to self-similar solutions
Surfaces Representation with Sharp Features Using Sqrt(3) and Loop Subdivision Schemes

description: This paper presents a hybrid algorithm that combines features form both Sqrt(3) and Loop Subdivision schemes. The algorithm aims at preserving sharp features and trim regions, during the surfaces subdivision, using a set of rules. The implementation is nontrivial due to the computational, topological, and smoothness constraints, which should be satisfied by the underlying surface. The fundamental innovation, in this research work, is the ability to preserve sharp features anywhere on a surface. In addition, the resulting representation remains within the multiresolution subdivision framework. Preserving the original representation has a core advantage that all the applicable operations to the multiresolution subdivision surfaces can subsequently be applied to the edited model. Experimental results, including surfaces coarsening and smoothing, were performed using the proposed algorithm for validation purposes, and the results revealed that the proposed algorithm outperforms the other recent state of the art algorithms.

Ο ρόλος του συναλλακτικού και σχεσιακού ψυχολογικού συμβολαίου αναφέρεται στις εργασιακές σχέσεις που αναπτύσσονται μεταξύ εργαζομένων και επιχείρησης και πιο συγκεκριμένα στις πεποιθήσεις τους για τους όρους και τις συνθήκες που διέπουν τις σχέσεις αυτές. Η εμπειρική έρευνα διεξήχθη προς το τέλος του έτους 2022, όπου διανεμήθηκε δομημένο ερωτηματολόγιο με ερωτήσεις κλειστού τύπου διαβαθμισμένης κλίμακας σε εργαζόμενα στελέχη εταιρειών. Συγκεντρώθηκαν έγκυρα συμπληρωμένα ερωτηματολόγια από 164 εργαζόμενους, οι οποίοι αποτελούν το τελικό δείγμα της έρευνας. Από τα αποτελέσματα της έρευνας, διαπιστώθηκε ότι το σχεσιακό ψυχολογικό συμβόλαιο επηρεάζει θετικά τις εργασιακές στάσεις, όπως η οργανωσιακή αφοσίωση και η ευημερία από την εργασία, οι οποίες με τη σειρά τους επηρεάζουν θετικά την εκπλήρωση των υποσχέσεων των εργαζομένων. Διαπιστώθηκε επίσης ότι τόσο το ψυχολογικό συμβόλαιο, όσο και η ευημερία των εργαζομένων, επηρεάζεται από παράγοντες όπως η ηλικία ή η εργασιακή τους εμπειρία, το οποίο με τη σειρά του σχετίζεται με την κατάσταση στην οποία μπορεί να βρίσκεται κάποιος εργαζόμενος επαγγελματικά. Τέλος, ένα σημαντικό εύρημα είναι ότι η πλειοψηφία των εργαζομένων παρουσιάζει ευημερία στην εργασία του, την ίδια στιγμή όπου οι δείκτες του σχεσιακού συμβολαίου είναι υψηλοί. Με βάση λοιπόν τα αποτελέσματα της έρευνας, μπορεί να διατυπωθεί το γενικό συμπέρασμα ότι η ικανοποίηση του ψυχολογικού συμβολαίου επηρεάζει θετικά την ευημερία των εργαζομένων, και επακολούθως τις εργασιακές στάσεις και τη συνολική εργασιακή απόδοση.

description: Στην παρούσα εργασία εξετάζεται πρώτον η έννοια της δημοκρατίας, με ανάλυση του ορισμού,των προϋποθέσεών της, και της ιστορικής της εξέλιξης από την αρχαιότητα έως τις μέρες μας.Δίνεται έμφαση στους θεμέλιους πυλώνες και τα χαρακτηριστικά της δημοκρατίας, καθώς και στις αντιθέσεις μεταξύ αρχαίας και νεωτερικής δημοκρατίας. Εξετάζεται επίσης η έννοια των πολιτικών συστημάτων και η σχέση των πολιτικών θεσμών με την ανάπτυξη. Στο δεύτερο κεφάλαιο, εστιάζουμε στη μοντερνοποίηση και τη σύνδεσή της με τη δημοκρατία. Εξηγείται η έννοια της μοντερνοποίησης, με εστίαση στην κλασική θεωρία μοντερνοποίησης και τα στάδιά της. Επιπλέον, αναλύεται η θεωρία του Lipset (1959), εξετάζοντας τη σχέση μεταξύ μοντερνοποίησης και δημοκρατίας. Επίσης εξετάζουμε τη σχέση μεταξύ του εισοδήματος ανά κεφαλήν και της δημοκρατίας.Βρήκαμε πως συνήθως υπάρχει θετική σχέση ανάμεσα στην οικονομική ευημερία και τη σταθερότητα της δημοκρατίας. Επιπλέον, αναφέραμε ότι ορισμένες θεωρίες υποστηρίζουν πως η δημοκρατία αποτελεί προϋπόθεση για την οικονομική ανάπτυξη. Ωστόσο, επισημάναμε πως αυτή η σχέση είναι πολύπλοκη και υπάρχουν πολλοί παράγοντες που μπορούν να την επηρεάσουν. Επίσης, αναγνωρίσαμε ότι υπάρχουν εξαιρέσεις, όπου πλούσιες χώρες δεν είναι δημοκρατίες και αντίστροφα, λόγω πολιτικών και πολιτιστικών παραδόσεων. Στο ερευνητικό μέρος εξετάσαμε τη σχέση μεταξύ δημοκρατίας και οικονομικής μεγέθυνσης σε πέντε χώρες: Ηνωμένες Πολιτείες, Ηνωμένο Βασίλειο, Καναδάς, Αυστραλία και Ελλάδα. Με τη χρήση στατιστικών μεθόδων, όπως η γραμμική παλινδρόμηση, αναλύονται οι τάσεις των δεδομένων για τη διάρκεια δεκαετίας (2010-2021). Από τα αποτελέσματα προκύπτει ότι υπάρχει θετική συσχέτιση μεταξύ του επιπέδου δημοκρατίας και του ΑΕΠ ανά κεφαλή. Οι χώρες με υψηλότερα επίπεδα δημοκρατίας φαίνεται να έχουν επίσης υψηλότερα επίπεδα οικονομικής ανάπτυξης. Ωστόσο, αυτή η σχέση δεν είναι απολύτως γραμμική και μπορεί να επηρεάζεται από διάφορους παράγοντες. Το περιεχόμενο αυτής της έρευνας αναδεικνύει τη σημασία της εξέτασης της σχέσης ανάμεσα στη δημοκρατία και την οικονομική μεγέθυνση, διότι αυτή η συσχέτιση έχει σημαντικές επιπτώσεις για την πολιτική λήψη και την ανάπτυξη των χωρών. Παρά τους περιορισμούς και τις πιθανές αδυναμίες της έρευνας, τα αποτελέσματα προσφέρουν σημαντικές ενδείξεις για την κατανόηση της πολυπλοκότητας της σχέσης ανάμεσα στην πολιτική δομή και την οικονομική ανάπτυξη.

description: Strain gradient continuum damage modelling has been applied to quasistatic brittle fracture within an approach based on a maximum energy-release rate principle. The model was implemented numerically, making use of the FEniCS open-source library. The considered model introduces non-locality by taking into account the strain gradient in the deformation energy. This allows for stable computations of crack propagation in differently notched samples. The model can take wedges into account, so that fracture onset can occur at wedges. Owing to the absence of a damage gradient term in the dissipated energy, the normal part of the damage gradient is not constrained on boundaries. Thus, non-orthogonal and non-parallel intersections between cracks and boundaries can be observed.

description: Flight dynamics is a topic often overlooked by operators of small satellites without propulsion systems, as two-line elements (TLE) are easily accessible and accurate enough for most ground segment needs. However, the advent of cheap and miniaturized global navigation satellite system (GNSS) receivers and laser retroreflectors as well as modern, easy-to-use, open-source software tools have made it easier to accurately determine an orbit or to identify a spacecraft in a swarm, which helps with improving the space situational awareness in orbits that are more and more crowded. In this paper, we present tools for small satellite missions to generate orbit predictions for the launch and early orbit phase (LEOP), identify spacecraft in a swarm after a rideshare launch, and carry out routine orbit determination from multiple sources of tracking data. The TUBIN mission’s LEOP phase set a new standard at Technische Universität Berlin: the first global positioning system (GPS) data were downloaded less than four hours after separation, orbit predictions allowed successful tracking by the ground stations, and the spacecraft could be identified in the swarm as soon as the TLE were released by Space-Track. Routine orbit determination from GPS and satellite laser ranging (SLR) tracking data was carried out over several months, and the quality of the orbit predictions was analyzed. The range residuals and prediction errors were found to be larger than those of most SLR missions, which was due to the difficulty of modeling the atmospheric drag of a tumbling, non-spherical spacecraft at low orbital altitudes.

description: Health literacy (HL) is a competence to find, understand, appraise, and apply health information and is necessary to maneuver the health system successfully. People with low HL are, e.g., under the risk of poor quality and safety of care. Previous research has shown that low HL is more prevalent among, e.g., people with lower social status, lower educational level, and among the elderly. In Germany, people with substitutive private health insurance (PHI) account for 11% of the population and tend to have a higher level of education and social status, but in-detail assessments of their HL are missing so far. Therefore, this study aimed to investigate the HL of PHI insureds in Germany, and to analyze their assessment of the health system according to their HL level. In 2018, 20,000 PHI insureds were invited to participate in a survey, which contained the HLS-EU-Q16, and items covering patient characteristics and the World Health Organization health systems framework goals (e.g., access, quality, safety, responsiveness). Low HL was found for 46.2% of respondents and was more prevalent, e.g., among men and insureds with a low subjective social status. The health system performance was perceived poorer by respondents with low HL. Future initiatives to strengthen health systems should focus on promoting HL.

description: Aims. The phase scintillation of the European Space Agency's (ESA) Venus Express (VEX) spacecraft telemetry signal was observed at X-band (λ= 3.6 cm) with a number of radio telescopes of the European VLBI Network (EVN) in the period 2009-2013. Methods. We found a phase fluctuation spectrum along the Venus orbit with a nearly constant spectral index of -2.42 +/-0.25 over the full range of solar elongation angles from 0° to 45°, which is consistent with Kolmogorov turbulence. Radio astronomical observations of spacecraft signals within the solar system give a unique opportunity to study the temporal behaviour of the signal's phase fluctuations caused by its propagation through the interplanetary plasma and the Earth's ionosphere. This gives complementary data to the classical interplanetary scintillation (IPS) study based on observations of the flux variability of distant natural radio sources. Results. We present here our technique and the results on IPS. We compare these with the total electron content (TEC) for the line of sight through the solar wind. Finally, we evaluate the applicability of the presented technique to phase-referencing Very Long Baseline Interferometry (VLBI) and Doppler observations of currently operational and prospective space missions.

description: This paper presents results of dependency parsing of Old French, a language which is poorly standardized at the lexical level, and which displays a relatively free word order. The work is carried out on five distinct sample texts extracted from the dependency treebank Syntactic Reference Corpus of Medieval French (SRCMF). Following Achim Stein's previous work, we have trained the Mate parser on each sub-corpus and cross-validated the results. We show that the parsing efficiency is diminished by the greater lexical variation of Old French compared to parse results on modern French. In order to improve the result of the POS tagging step in the parsing process, we applied a pre-treatment to the data, comparing two distinct strategies: one using a slightly post-treated version of the TreeTagger trained on Old French by Stein, and a CRF trained on the texts, enriched with external resources. The CRF version outperforms every other approach.
An Introductory Review of Input-Output Analysis in Sustainability Sciences Including Potential Implications of Aggregation

description: Input-output analysis has become a widely established method in sustainability sciences. It is primarily used in macroeconomic footprint analyses for allocating an economy’s externalities among the agents in that economy based on the agents’ input-output interdependencies. However, databases for input-output analyses are commonly compiled by aggregating data. Aggregation of input-output data inevitably leads to a loss of information and in some instances can lead to misinformed decision-making. The goal of this paper is to provide a simple hands-on numerical introduction to input-output analysis including the potential implications of data aggregation in an original manner. First, the calculation of production-based and consumption-based inventories is introduced based on a dummy 2 × 2 input-output table. Next, the inventories of the 2 × 2 input-output table are compared with the production-based and consumption-based inventories of a corresponding non-aggregated 4 × 4 input-output table. A comparison of the inventories of both dummy input-output tables allows for an exemplary demonstration of inaccurate allocation as a result of data aggregation and to conclude on potential implications for decision-making. Overall, this work offers a succinct and numerically substantiated introductory review of input-output analysis for practitioners in sustainability sciences including the potential implications of aggregation of input-output data. Its simplistic approach sets this work apart from other publications on aggregation in input-output analysis that are founded in economics or econometrics.

description: This paper deals with the experimental characterization of the collapse of wet granular columns in the pendular state, with the purpose of collecting data on triggering and jamming phenomena in wet granular media. The final deposit shape and the runout dynamics were studied for samples of glass beads, varying particle diameter, liquid surface tension, and liquid amount. We show how the runout distance decreases with increasing water amount (reaching a plateau for $w>1 \%$) and increases with increasing Bond number, while the top and toe angles and the final deposit height increase with increasing water amount and decrease with decreasing Bond number. Dimensional analysis allowed to discuss possible scalings for the runout length and the top and toe angles: a satisfying scaling was found, based on the combination of Bond number and liquid amount.

description: Netzwerke der wissenschaftlichen Weiterbildung agieren praxis-orientiert und dienen als Plattform der Kooperation sowie der bildungspolitischen Einflussnahme. Der Beitrag bietet eine europäisch orientierte Definition wissenschaftlicher Weiterbildung an. Der Fokus liegt dabei auf wissenschaftlicher Weiterbildung als hochschulischer Besonderheit. Vorgestellt werden Netzwerke des Lebenslangen Lernens und ihre hochschulpolitische Wirkung auf institutioneller, regionaler, nationaler, europäischer und internationaler Ebene. Darüber hinaus werden Ziele, Aufgaben, das Selbstverständnis sowie die organisationalen Strukturen verschiedener Netzwerke exemplarisch betrachtet und verglichen. Im Mittelpunkt der Überlegungen steht dabei die Frage: Wie funktionieren Kommunikation, Informationsaustausch und Verbreitung zwischen den verschiedenen Netzwerk-Partner_innen, vor allem im Hinblick darauf, dass die einzelnen Hochschulen jeweils spezifische Schwerpunkte hinsichtlich des Fächerspektrums und damit des jeweiligen Profils und der Zielgruppen aufweisen? Gibt es gemeinsame Ziele, auf die sich die Netzwerk-Mitglieder verständigen? Wie kann diese Vielfalt in Stellungnahmen und Positionspapieren transportiert werden? Welche Wirkung können Netzwerke in hochschulpolitischer Hinsicht auf institutioneller, regionaler, nationaler, europäischer und internationaler Ebene erzielen und gibt es Indikatoren, an denen sich diese Wirkung messen lässt?

subject: active particles

description: We present a Brownian dynamics study of a 2D bath of active particles interacting among each other through usual steric interactions and, additionally, via non-reciprocal avoidant orientational interactions. We motivate them by the fact that the two flagella of the alga Chlamydomonas interact sterically with nearby surfaces such that a torque acts on the alga. As expected, in most cases such interactions disrupt the motility-induced particle clustering in active baths. Surprisingly, however, we find that the active particles can self-organize into collectively moving flocks if the range of non-reciprocal interactions is close to that of steric interactions. We observe that the flocking motion can manifest itself through a variety of structural forms, spanning from single dense bands to multiple moderately-dense stripes, which are highly dynamic. The flocking order parameter is found to be only weakly dependent on the underlying flock structure. Together with the variance of the local-density distribution, one can clearly group the flocking motion into the two separate band and dynamic-stripes states.

description: Este trabajo está realizado con la finalidad de compartir conocimientos acerca de un procedimiento habitual dentro del ambiente hospitalario como es la Nebulización. Para ello debemos repasar un poco de historia y mencionar que la verdadera terapia inhalatoria empieza en la segunda mitad del siglo XIX, en 1849 en el Balneario de Euzet-les-Bains (Francia), Auphan, médico del mismo país, construye una sala de inhalación vaporarium en la que una columna de agua, que chocaba contra la pared, producía un fino aerosol de partículas acuosas. Unos años antes, en 1828, Schneider y Waltz (Suiza) habían inventado un pulverizador, el hidroconion, que reducía los líquidos a lluvia menuda. En 1901, Takamine (Japón) y Aldrich (Alemania) aislaron la adrenalina de glándulas adrenales y se usó por primera vez en el tratamiento del asma bronquial, mediante nebulización. En nuestro país no existen registros sobre el inicio de la nebulización, pero se sabe que el Servicio de Neumología del Hospital Real San Andrés es uno de los primeros y pioneros de la neumología peruana, fue el primer nosocomio de los españoles y el primer local de lo que sería la Facultad de Medicina de San Marcos, y empezó a funcionar en 1811 como tal, con Hipólito Unanue como uno de sus fundadores. El Hospital de San Andrés siguió funcionando hasta el 8 de marzo de 1875, cuando todos los pacientes pasaron al recién inaugurado Hospital Dos de Mayo. A nivel regional, según historiadores, en el Hospital Goyeneche de Arequipa creado en 1912 se llegó a utilizar por primera vez el nebulizador en pacientes con enfermedades respiratorias.
Wissenschaftliche Weiterbildung als „Transfer“

description: Wissenschaftliche Weiterbildung im Sinne eines Transfers zu konzeptualisieren, erfordert, so die eingenommene Perspektive in dem Beitrag, eine nähere Auseinandersetzung mit den Voraussetzungen des Verständnisses von Transfer. Im Rahmen einer begriffshistorischen Perspektive wird daher Transfer als ein forschungsrelevanter Begriff in den Blick genommen, der nicht terminologisch im Sinne einer Nominaldefinition festzulegen ist, sondern im Sinne einer „Begrifflichkeit“ selber einem historisch-epistemischen Wandel unterworfen ist. Unter Berücksichtigung eines relationslogischen Zugangs wird im Beitrag dafür plädiert, die bislang unbeachtete Mehrdeutigkeit des Transferbegriffs aus der Latenz zu heben, ihn darüber kontingent zu setzen und als „transformativen Transfer“ zu respezifizieren.

description: Maximal correlation is a measure of correlation for bipartite distributions. This measure has two intriguing features: (1) it is monotone under local stochastic maps; (2) it gives the same number when computed on i.i.d. copies of a pair of random variables. This measure of correlation has recently been generalized for bipartite quantum states, for which the same properties have been proved. In this paper, based on maximal correlation, we define a new measure of entanglement which we call maximal entanglement. We show that this measure of entanglement is faithful (is zero on separable states and positive on entangled states), is monotone under local quantum operations, and gives the same number when computed on tensor powers of a bipartite state.

description: Der Beitrag stellt die Grundideen des Hochschulentwicklungsprojekts „VerAn – Vernetzung der Anerkennungsberatung für ein Hochschulstudium“ und seine Projektmaßnahmen vor und gibt Auskunft über die Erfahrungen, die im ersten Projektjahr gemacht wurden. Das Projekt strebt eine themenbezogene Vernetzung von Beratungseinrichtungen an, die die Anerkennungsberatung für Menschen mit im Ausland erworbenen Qualifikationen entweder ins Zentrum ihrer Beratungstätigkeit stellen oder anlassbezogen damit befasst sind. Im Laufe des ersten Projektjahres wurden strukturelle Problemlagen deutlich, die auf das zugrundeliegende Verständnis von Internationalisierung zurückgeführt werden können. Zudem werden neue Aufgaben an die wissenschaftliche Weiterbildung gerichtet, da der Prozess der Anerkennung meist mit der Notwendigkeit der (wissenschaftlichen) Nachqualifizierung einhergeht

description: Perturbative scattering amplitudes in gauge theories have remarkable simplicity and hidden infinite dimensional symmetries that are completely obscured in the conventional formulation of field theory using Feynman diagrams. This suggests the existence of a new understanding for scattering amplitudes where locality and unitarity do not play a central role but are derived consequences from a different starting point. In this note we provide such an understanding for N=4 SYM scattering amplitudes in the planar limit, which we identify as ``the volume" of a new mathematical object--the Amplituhedron--generalizing the positive Grassmannian. Locality and unitarity emerge hand-in-hand from positive geometry.

description: The dynamical properties and diffusive behavior of a collection of mutually interacting particles are numerically investigated for two types of long-range interparticle interactions: Coulomb-electrostatic and dipole-electrodynamic. It is shown that when the particles are uniformly distributed throughout the accessible space, the self-diffusion coefficient is always lowered by the considered interparticle interactions, irrespective of their attractive or repulsive character. This fact is also confirmed by a simple model to compute the correction to the Brownian diffusion coefficient due to the interactions among the particles. These interactions are also responsible for the onset of dynamical chaos and an associated chaotic diffusion which still follows an Einstein-Fick like law for the mean square displacement as a function of time. Transitional phenomena are observed for Coulomb-electrostatic (repulsive) and dipole-electrodynamic (attractive) interactions considered both separately and in competition. The outcomes reported in this paper clearly indicate a feasible experimental method to probe the activation of resonant electrodynamic interactions among biomolecules.

Rydberg atoms in hollow-core photonic crystal fibres

description: The exceptionally large polarisability of highly excited Rydberg atoms (six orders of magnitude higher than ground-state atoms) makes them of great interest in fields such as quantum optics, quantum computing, quantum simulation and metrology. If however they are to be used routinely in applications, a major requirement is their integration into technically feasible, miniaturised devices. Here we show that a Rydberg medium based on room temperature caesium vapour can be confined in broadband-guiding kagome-style hollow-core photonic crystal fibres. Three-photon spectroscopy performed on a caesium-filled fibre detects Rydberg states up to a principal quantum number of n = 40. Besides small energy level shifts we observe narrow lines confirming the coherence of the Rydberg excitation. Using different Rydberg states and core diameters we study the influence of confinement within the fibre core after different exposure times. Understanding these effects is essential for the successful future development of novel applications based on integrated room temperature Rydberg systems.
