description: Research data provide evidence for the validation of scientific hypotheses in most areas of science. Open access to them is the basis for true peer review of scientific results and publications. Hence, research data are at the heart of the scientific method as a whole. The value of openly sharing research data has by now been recognized by scientists, funders and politicians. Today, new research results are increasingly obtained by drawing on existing data. Many organisations such as the Research Data Alliance (RDA), the goFAIR initiative, and not least IUPAC are supporting and promoting the collection and curation of research data. One of the remaining challenges is to find matching data sets, to understand them and to reuse them for your own purpose. As a consequence, we urgently need better research data management.

description: We compare our steeply textured glasses, two antireflective glasses and standard glasses under outdoor
conditions at different sites in Germany, Spain (desert like area) and China (tropical, hot, humid). On textured glasses
no dust accumulation higher than on non-textured glasses could be found after 36 months. On AR coated glasses we
additionally see a faster drying due to the hyrdophilicity of these types of coatings. So the efficiency gain kept stable
over a long period of time. We now show the dependency of output power due to climate impact as dust, rain and
irradiation. We conclude that still after 3 years using our new types of glasses for PV modules allows not only
increasing the electricity yield of solar modules in laboratory but does also keeps stable over long time period outdoor
that means no dust accumulation and easier-to-clean functionality over longer periods due to wind or rain . The
efficiency increase for modules with standard multicrystalline cells as installed outdoor lies in the 2% to 8% range and
for higher angles of incidence (morning and evening hours) even between 10% and 40%.

description: In this paper we carry out a low-temperature scan of the phase diagram of dense two-color QCD with $N_f=2$ quarks. The study is conducted using lattice simulation with rooted staggered quarks. At small chemical potential we observe the hadronic phase, where the theory is in a confining state, chiral symmetry is broken, the baryon density is zero and there is no diquark condensate. At the critical point $μ= m_π/2$ we observe the expected second order transition to Bose-Einstein condensation of scalar diquarks. In this phase the system is still in confinement in conjunction with non-zero baryon density, but the chiral symmetry is restored in the chiral limit. We have also found that in the first two phases the system is well described by chiral perturbation theory. For larger values of the chemical potential the system turns into another phase, where the relevant degrees of freedom are fermions residing inside the Fermi sphere, and the diquark condensation takes place on the Fermi surface. In this phase the system is still in confinement, chiral symmetry is restored and the system is very similar to the quarkyonic state predicted by SU($N_c$) theory at large $N_c$.

description: The concept of an $i$-symmetrization is introduced, which provides a convenient framework for most of the familiar symmetrization processes on convex sets. Various properties of $i$-symmetrizations are introduced and the relations between them investigated. New expressions are provided for the Steiner and Minkowski symmetrals of a compact convex set which exhibit a dual relationship between them. Characterizations of Steiner, Minkowski and central symmetrization, in terms of natural properties that they enjoy, are given and examples are provided to show that none of the assumptions made can be dropped or significantly weakened. Other familiar symmetrizations, such as Schwarz symmetrization, are discussed and several new ones introduced.

description: This paper addresses in-situ transmission measurements on growing silicon thin films for
photovoltaic applications. It is shown that deposition rate, film crystallinity and substrate roughness can be
detected in-situ by analyzing the transmission of the plasma emission through the thin silicon layers during a
PECVD process. The industrial relevance is proven by depositing silicon thin films on rough, transparent and
conductive ZnO:Al layers which are optimized for light trapping in solar cells. In spite of the roughness of the
ZnO:Al accurate thickness information up to a thickness of about 900 nm can be obtained with in-situ
transmission measurements. The results show that in-situ transmission measurements can be used as process
control in the industrial fabrication of thin-film silicon solar cells due to the simplicity of the measurement setup
and a convincing resolution power. Thus, with a low-cost system quality control of solar modules can be
performed in-situ in an early fabrication process step.
title: The use of objects in the construction, expression and negotiation of identities: a case study of Maya dolls from Mexico and Guatemala
Creators: name: Jackson, Emma Victoria
Publisher: name: University of Reading
Year: 2021

description: This thesis examines an under-assessed and under-valued cultural text: the souvenir doll. These dolls, clothed in national, regional or ethnic dress, have often been dismissed as “kitsch” objects of little ethnographic or aesthetic significance. However, by focusing on dolls handmade for the tourist market by the Kaqchikel Maya of San Antonio Aguas Calientes, Guatemala and the Tzotzil Maya of Chamula in Chiapas, Mexico, this thesis demonstrates the importance of these dolls for the expression and construction of a range of identity categories, both for their producers and receivers. These dolls are notable since they are dressed in the same type of handwoven textiles as the women who usually make them. By extending the life story approaches associated with Igor Kopytoff (1986) and Arjun Appadurai (1986) to the source materials that form an object, this thesis traces the production of these dolls from thread level and, in doing so, captures the profound importance of the weaving process and woven textiles for the construction and expression of Maya identities at a personal and collective level. This thesis continues to apply a life story approach to trace the various paths the dolls may take once they have been sold. UK-based fieldwork, along with data collected in Guatemala and Mexico, shows that when the dolls are consumed they are reconfigured to meet the identity needs of the consumer. This reconfiguration, however, often simultaneously flattens or erases the local specificities and indigenous identities embodied by the dolls. This thesis demonstrates that dolls produced by indigenous people specifically for external consumption can be read as texts that reveal important socio-political processes and effects and, more specifically, offers a unique exploration of the production and consumption of Maya dolls that is further enhanced by its comparative, cross-border scope.

description: Let $π:X\to \mathbb{P}^1_{\mathbb{Q}}$ be a non-singular conic bundle over $\mathbb{Q}$ having $n$ non-split fibres and denote by $N(π,B)$ the cardinality of the fibres of Weil height at most $B$ that possess a rational point. Serre showed in $1990$ that a direct application of the large sieve yields $$N(π,B)\ll B^2(\log B)^{-n/2}$$ and raised the problem of proving that this is the true order of magnitude of $N(π,B)$ under the necessary assumption that there exists at least one smooth fibre with a rational point. We solve this problem for all non-singular conic bundles of rank at most $3$. Our method comprises the use of Hooley neutralisers, estimating divisor sums over values of binary forms, and an application of the Rosser-Iwaniec sieve.

p-type substrate solar cells during the different test condition. The intensity of light source was 0.5 -1 sun with
1.5 AM spectrum. The temperature of solar cells was controled in the range of 15 - 70 °C. The samples of solar cells
was chosen from nine sets of solar cells produced by variety technology and with variety parameters. The life time of
charge carriers, VA characteristic, electroluniniscence characteristic were set up after phosphor diffusion. After light
degradation in variety condition was determinated again and compare with starting parameters. The samples were
regenerated by high temperature with and without light and parameters were measured again. The whole experiment
was analyzed and the correlation was made.

description: This paper reports the measured degradation rates of seven kinds of state-of-the-art mc-Si and pc-Si
PV modules over an approximately 2-year period. In an experiment performed at Sede Boqer in the Negev Desert,
the modules, each connected to a resistive load, were placed on a fixed open-rack mount and exposed to the
elements. Approximately twice a year, on cloudless days, the modules were disconnected from their loads, cleaned,
and their I-V curves measured at noontime. This paper discusses the time-dependence of the results. The precision of
the measurements was sufficiently high to enable the quantification of module degradation rates of less than 1 % per
year within the time span of the present project.

description: We present the largest kinship recognition dataset to date, Families in the Wild (FIW). Motivated by the lack of a single, unified dataset for kinship recognition, we aim to provide a dataset that captivates the interest of the research community. With only a small team, we were able to collect, organize, and label over 10,000 family photos of 1,000 families with our annotation tool designed to mark complex hierarchical relationships and local label information in a quick and efficient manner. We include several benchmarks for two image-based tasks, kinship verification and family recognition. For this, we incorporate several visual features and metric learning methods as baselines. Also, we demonstrate that a pre-trained Convolutional Neural Network (CNN) as an off-the-shelf feature extractor outperforms the other feature types. Then, results were further boosted by fine-tuning two deep CNNs on FIW data: (1) for kinship verification, a triplet loss function was learned on top of the network of pre-trained weights; (2) for family recognition, a family-specific softmax classifier was added to the network.

description: PV modules are periodically cleaned, particularly in large grid-connect photovoltaic plants, in order to
avoid losses caused by dust accumulation. However, this maintenance task is often expensive, especially in those
areas with water shortage. For reducing the tasks of cleaning, a new hybrid self-cleaning coating has been developed.
The coating has several advantages; (1) Higher transmittance (2) Self-cleaning property (3) Increased durability (4)
Simply coating method. In this paper it is shown the effect of the new hybrid self-cleaning coating for PV modules
and the losses caused by accumulated dust at outdoor exposure in Spain and Japan. In Spain, it is the high-level
irradiation area with dust particles in air and absence of rain for long periods. The dust losses are greater for the
modules without self-cleaning coating. The transmittance losses reached values near the 15%. This value decreases to
13% in modules with self-cleaning coating. In Kawasaki, Japan, the power losses of the PV module with coating
were 7% less than that without coating after 1 year exposure. In this case the main components of dust were organic
materials, and it was periodically rained.
A holographic model for black hole complementarity

description: We explore a version of black hole complementarity, where an approximate semiclassical effective field theory for interior infalling degrees of freedom emerges holographically from an exact evolution of exterior degrees of freedom. The infalling degrees of freedom have a complementary description in terms of outgoing Hawking radiation and must eventually decohere with respect to the exterior Hamiltonian, leading to a breakdown of the semiclassical description for an infaller. Trace distance is used to quantify the difference between the complementary time evolutions, and to define a decoherence time. We propose a dictionary where the evolution with respect to the bulk effective Hamiltonian corresponds to mean field evolution in the holographic theory. In a particular model for the holographic theory, which exhibits fast scrambling, the decoherence time coincides with the scrambling time. The results support the hypothesis that decoherence of the infalling holographic state and disruptive bulk effects near the curvature singularity are complementary descriptions of the same physics, which is an important step toward resolving the black hole information paradox.

description: For the deposition of a-Si:H solar cells, a single-chamber process was developed. A singlechamber
fabrication of a-Si:H solar cells in an inline 40 × 40 cm2 deposition system with an initial efficiency of
 = 10.3 % is achieved. To avoid boron cross-contamination, usually a critical issue for single-chamber
processes, reactor treatments prior to the i-layer deposition are required. Three types of treatments are compared
for their effectivity and required treatment time, namely a CO2-plasma, a reactor evacuation and a cell deposition
without plasma stop. The deposition without plasma-stop did not lead to state-of-the-art solar cell performances.
A strong boron cross-contamination leads to losses in conversion efficiency, especially in the short wavelength
range. The two other types of treatments led to the deposition of high-quality solar cells. The required treatment
time was 15 min and 27 min for chamber evacuation and CO2-plasma treatment, respectively. For the “process
chamber evacuation” with the substrate remaining in the recipient (in-situ), subsequent to the deposition of the
p-layer the chamber is evacuated to 9×10-7 mbar prior to the deposition of the i-layer. For the device designs
applied in this work, the influence on the boron cross-contamination is not significantly different.

description: By a finite type-graph we mean a graph whose set of vertices is the set of all $k$-subsets of $[n]=\{1,2,\ldots, n\}$ for some integers $n\ge k\ge 1$, and in which two such sets are adjacent if and only if they realise a certain order type specified in advance. Examples of such graphs have been investigated in a great variety of contexts in the literature with particular attention being paid to their chromatic number. In recent joint work with Tomasz Łuczak, two of the authors embarked on a systematic study of the chromatic numbers of such type-graphs, formulated a general conjecture determining this number up to a multiplicative factor, and proved various results of this kind. In this article we fully prove this conjecture.

description: The macroscopic surface electric susceptibility determines the linear optical properties of an insulating single-layer two-dimensional atomic crystal, and can be expressed in terms of the microscopic polarizability of the atoms. We compute the local electric field acting on a single atom, both for the static and the dynamic case, as the superposition of the external applied electric field and the fields generated by the induced dipoles in the crystal. We find that, in the dynamic case, retardation effects dephase the local electric field with respect to the incident one. This explains why the Fresnel coefficients of a single-layer two-dimensional atomic crystal are intrinsically complex quantities, even when a null macroscopic surface conductivity is assumed.

description: The results of a round-robin experiment, which determines the electrical quality of silicon, are
presented. Five participants measure the excess charge carrier lifetime (using RF-PCD) and the excess charge carrier
decay time (using MW-PCD) on mono- and multicrystalline ingots as well as on adjacent surface passivated wafers.
Applying a defined set of measurement parameters a quite good reproducibility is found for each type of
measurement. The standard deviation within the measurement methods ranges from 3 % to maximal 19 %. Between
the measurement methods large differences are found, which are explained by the properties of each measurement
method. For the investigated samples the estimated lifetime determined by RF-PCD on the ingot comes closest to the
lifetime measured on the surface passivated wafers.

description: Background
 Problem-based learning (PBL) is an effective student-centric learning tool that integrates multiple disciplines and learning domains such as Cognitive, psychomotor, and affective. Peer learning in small groups creates a collaborative learning environment. To further extend the camaraderie learning dynamic and widen the learning domains, this project aims to build a module encompassing PBL with cross-grouping & games activities and assessing the learning outcomes & perceptions in relation to traditional lectures.

 Summary Of Work
 The Pathology department coordinated three modules on ‘Covid & inflammation’, ‘Hemolytic anemia’, & ‘breast carcinoma’ in integration with clinical and paraclinical disciplines among second- year MBBS students (n=60). Four groups simultaneously worked on four PBL problems exclusively, followed by cross-grouping the students and learning all four problems from their peers. A faculty facilitated each group of 15 students by further dividing them into two groups. Psychomotor, affective activities and games like crossword, card-matching, and picture connections were included. At the end of the week, an integrated assessment & classroom presentations were organized. Pre (T1) & post (T2) tests of the traditional lectures on the same topic and a post (T3) test after module completion were analyzed. Feedback via questionnaires and focus group discussions (FGD) was collected.

 Summary Of Results
 Repeated measure ANOVA among the test scores (T1, T2, T3) were statistically significant for each module. On analyzing the questionnaires, a majority felt PBL developed their analytical thinking & deeper understanding; ‘Cross grouping’ helped to learn concepts from peers. ‘Psychomotor activity’ was highly engaging; ‘Affective domain’ assignments improved their empathy, while ‘Games’ were fun. On ‘thematic analysis’ of FGD transcripts, we generated the following five themes: Higher level cognitive skills, Learner-centred learning, Different modes of thinking, Leader & member of a team, and Intrinsic motivation.
 Discussion And Conclusion
 This module provides holistic learning, enabling students to apply their basic science knowledge to solve clinical problems. Some barriers include non-cooperative peers and less preparation for cross- grouping, which resolved after repeated sessions. Blending various learning tools help students with different learning styles & strengths, thereby creating an inclusive learning environment. Our future vision is to train more faculty and shift to the PBL curriculum.

description: Photoluminescence (PL) measurements are usually realized using near-infrared laser excitations that
provide uniform carrier generation profiles in the photovoltaic device or sample. This work analyses theoretically
and proves experimentally that illuminating a sample with a set of wavelengths and capturing the resulting
luminescence signal yields meaningful information on the spectral response of the device: besides the effective
lifetime, the quantum-efficiency of the structure can be characterized. The first part of this paper describes the basic
theory of the method and quantifies the dependence of the resulting PL on the applied wavelength; the analysis of the
spectrally resolved PL signals takes into account the reabsorption in the bulk, and leads to the extraction of the bulk
lifetime, emitter saturation current and surface recombination on both sides of the sample. Afterwards, the PL
characterization setup –optics, sample position, excitation and detectors- is presented, with special attention to the
light source; it consists of three LED sets, with their emission centred at 460 nm (blue), 520 nm (green) and 620 nm
(red). Finally, in order to show the validity of the concept, some experimental results are presented and discussed.

description: Background

 Supervised clinical placements within community settings (primary care) are increasingly included in healthcare education programs. However, within medical curricula, most placements are within general medical practice and supervisor experiences are well documented in this area. An innovative transformation in the Sydney Medical Program includes community placements which incorporate medical student supervision within a variety of interprofessional settings. Primary care is a relatively new medium for interprofessional learning and there is limited research in this area. The aim of this qualitative study, grounded in an interpretivist paradigm, was to gain an in-depth understanding of medical and non-medical supervisors’ teaching experiences, in this context, and to explore influential factors affecting their recruitment and ongoing engagement within this program.

 Summary of Work

 Semi-structured interviews were conducted with 20 supervisors from community health professions including allied health, dentistry, pharmacy, psychology and medicine. Reflexive thematic analysis of transcripts was undertaken using self-determination as a theoretical lens.

 Summary of Results

 We generated three key themes related to supervisor experiences: (1) Motivation is strongly influenced by their personal interest in teaching, the opportunity to advocate for their profession and their desire to create interprofessional networks; (2) Perceptions of capabilities supervisors could impart to medical students through knowledge and skills transfer; enhancement of student collaborative and communication skills; and considering themselves as interprofessional roles models; and (3) Interprofessional community placements as platforms for learning about systems and processes in healthcare and adopting qualities relating to interprofessionalism.

 Discussion and Conclusion

 Understanding supervisors’ perceptions using a self-determination theory framework allows for a better understanding of drivers and barriers which could impact supervisor engagement in medical student interprofessional placements. Supported autonomy, faculty development and employing strategies to increase supervisor relatedness are key to forming sustainable partnerships in providing rich interprofessional student learning experiences

description: Recombination activity of (110)/ (100) direct silicon bonded interface contaminated by nickel and
copper diffused at different temperatures and durations was studied as a model of grain boundaries in multicrystalline
silicon using capacitance transient measurement. Temperature dependence of trap density of states of the nickel- and
copper-incorporated interface indicates an intensive peak, and hole capture cross section of the nickel-incorporated
interface drastically increased by three orders of magnitude at annealing temperatures from 350°C to 550°C. It is
suggested that the peak in trap density of states is due to diffusion behavior of metal, and the significant change in
hole capture cross section is caused by chemical shift of captured nickel at the interface.

description: The influence of front and rear texture of thin-film microcrystalline silicon solar cells on light trapping
is evaluated by characterizing solar cell specimens with both superstrate (p-i-n) and substrate (n-i-p) configurations
that have a variety of surface morphologies including intentionally polished flat surfaces. It is demonstrated that the
front texture enhances light absorption and external quantum efficiency from the visible to the near-infrared region,
while the rear texture increases these properties only at wavelengths longer than around 600 nm. The photocurrent
enhancement by the rear texture is comparable or superior to that by the front texture, especially in n-i-p solar cells
with a thin transparent conductive oxide (TCO) layer on the front surface. Irrespective of the cell configuration,
parasitic absorption loss in solar cells is increased by the textures.

Large PV Power Plants and Distributed PV: System Aspects and Grid Connection

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 4251-4253
description: 1a power data of 18KW grid-connected PV power station in Wuhan is collected for PV grid-connected
inverter (GHI) efficiency research. The basic characteristics such as daily and monthly variation are analyzed, from
the instantaneous and energy average point. Utilizing the monthly variations, normalized operation and non-linear
regression, two different efficiency models have been presented. Results showed that: 1) The instantaneous GHI
efficiency has obvious daily variations, smaller in the morning and evening, larger in the medium time; and
fluctuating significantly for cloudy and rainy day. The year energy-averaged efficiency is 94.5%, lower than
European efficiency 95.1%. 2) Two kinds of models are verified by fitting inspection and independent prediction
inspection, separately. For the first method, the prediction efficiency is smaller than the actual value for steady larger
normalized input dc power, while with the second method, the result is opposite. 3) Applying the time constant
concept of circuit theory, the critical stable range of normalized input dc power (0.113-0.141pu) is calculated, for
further research on the corresponding solar irradiance range to avoid the low irradiance loss. These models can be
used for short-term power prediction of grid-connected PV system with improving the prediction accuracy under
morning, evening, cloudy and rainy day.
Allowed region and optimal measurement for information versus disturbance in quantum measurements

description: We present graphs of information versus disturbance for general quantum measurements of completely unknown states. Each piece of information and disturbance is quantified by two measures: (i) the Shannon entropy and estimation fidelity for the information and (ii) the operation fidelity and physical reversibility for the disturbance. These measures are calculated for a single outcome and are plotted on four types of information--disturbance planes to show their allowed regions. In addition, we discuss the graphs of these metrics averaged over all possible outcomes and the optimal measurements when saturating the upper bounds on the information for a given disturbance. The results considerably broaden the perspective of trade-offs between information and disturbances in quantum measurements.

description: This article studies the achievable guarantees on the error rates of certain learning algorithms, with particular focus on refining logarithmic factors. Many of the results are based on a general technique for obtaining bounds on the error rates of sample-consistent classifiers with monotonic error regions, in the realizable case. We prove bounds of this type expressed in terms of either the VC dimension or the sample compression size. This general technique also enables us to derive several new bounds on the error rates of general sample-consistent learning algorithms, as well as refined bounds on the label complexity of the CAL active learning algorithm. Additionally, we establish a simple necessary and sufficient condition for the existence of a distribution-free bound on the error rates of all sample-consistent learning rules, converging at a rate inversely proportional to the sample size. We also study learning in the presence of classification noise, deriving a new excess error rate guarantee for general VC classes under Tsybakov's noise condition, and establishing a simple and general necessary and sufficient condition for the minimax excess risk under bounded noise to converge at a rate inversely proportional to the sample size.

Thin Film Crystalline Silicon Solar Cells and Wafer Equivalents

description: 24th European Photovoltaic Solar Energy Conference, 21-25 September 2009, Hamburg, Germany; 2279-2285
description: A key cost driver for thin film silicon technologies in manufacturing is the plasma enhanced chemical
vapour deposition (PECVD) process necessary for the production of hydrogenated amorphous silicon. The crystalline silicon
on glass (CSG) technology used by CSG Solar can utilize dehydrogenated amorphous silicon and so offers a unique
advantage over other thin film silicon technologies in that a more cost effective evaporation process can be considered. This
paper reports developments in the e-beam deposition of silicon for PV applications, with a new record efficiency for a planar
e-beam deposited silicon thin film solar cell set at 6.7%. The silicon film was deposited at a remarkable 600 nm/min, 30
times faster than routinely achieved by PECVD. We also report developments in e-beam deposition on textured substrates
whereby light trapping resulted in a current exceeding 23 mA/cm2 and a record efficiency of 7.4% for a 12-cell 35-cm2
minimodule. The e-beam deposited base was 1.5 μm thick and light trapping was achieved using a silicon surface texture.

description: Complete Hamiltonian formalism is suggested for inertial waves in rotating incompressible fluid. Resonance three-wave interaction processes -- decay instability and confluence of two waves -- are shown to play a key role in the weakly nonlinear dynamics and statistics of inertial waves in the rapid rotation case. Future applications of the Hamiltonian approach in inertial wave theory are investigated and discussed.

Fermented foods are consumed throughout the world and substantially contribute to food security. Many fermented products rely on the participation of Bacillus species, but their contribution to food quality is not well documented. The purpose of this review is to highlight metabolic properties that relate to food quality and food safety. Most fermented foods that include Bacillus species use legumes or tubers as substrate and are traditionally prepared in East Asia, Africa, and South America. In food fermentations, Bacillus species produce amylases and proteases, extracellular polysaccharides and polypeptides, and lipopeptides with antimicrobial activity. The metabolic traits of bacilli also provide opportunities for use in food fermentations in which they do not traditionally occur.

description: 25th European Photovoltaic Solar Energy Conference and Exhibition / 5th World Conference on Photovoltaic Energy Conversion, 6-10 September 2010, Valencia, Spain; 2963-2966
description: Dangling-bond defects in microcrystalline-silicon (μc-Si:H) films grown at high rate are concentrated at the
interface especially at the surface, leading to a severe deterioration in the photovoltaic performance of relevant solar cells.
For overcoming this issue, we have attempted to use a novel interface-treatment method in fabrication process of solar
cells with μc-Si:H photo-active layer grown at high rate. Drastic decrease of surface dangling-bond has been observed in
electron-spin-resonance (ESR) measurements when thin amorphous silicon layer with low defect density is deposited on
the surface of μc-Si:H grown at high rate followed by thermal annealing. Thinking of the fact that this thin layer is
effective for the reduction of surface defects when the thermal annealing is performed after the deposition, we have
named this layer as the “compress layer” instead of “cap layer” or “buffer layer” used conventionally. Finally we have
demonstrated a drastic improvement of optoelectronic properties at p/ i interface adopting the compress layer through the
fabrication of high-efficiency single-junction n-i-p μc-Si:H solar cells whose i-layer is deposited at high rate of 2.3
nm/sec.

description: It is shown that a generic form of an antiferromagnetic wave function opens strong electron-phonon coupling channels in the iron-based superconductors. In the nonmagnetic state these channels exist locally on a single iron atom, but are canceled out between the two iron atoms in the primitive unit cell. Our findings are based on symmetry and the presence of an xz/yz Fermi surface near the M point and thus should be relevant for the known iron-based pnictide or chalcogenide superconductors.

description: We report a systematic study of temperature- and field-dependent charge ($\boldsymbolρ$) and entropy ($\mathbf{S}$) transport in the heavy-fermion superconductor CeIrIn$_5$. Its large positive thermopower $S_{xx}$ is typical of Ce-based Kondo lattice systems, and strong electronic correlations play an important role in enhancing the Nernst signal $S_{xy}$. By separating the off-diagonal Peltier coefficient $α_{xy}$ from $S_{xy}$, we find that $α_{xy}$ becomes positive and greatly enhanced at temperatures well above the bulk $T_c$. Compared with the non-magnetic analog LaIrIn$_5$, these results suggest vortexlike excitations in a precursor state to unconventional superconductivity in CeIrIn$_5$. This study sheds new light on the similarity of heavy-fermion and cuprate superconductors and on the possibility of states not characterized by the amplitude of an order parameter.
