description: We use powder neutron diffraction to study the spin and lattice structures of polycrystalline samples of nonsuperconducting PrFeAsO and superconducting PrFeAsO0.85F0.15 and PrFeAsO0.85. We find that PrFeAsO exhibits an abrupt structural phase transitions at 153 K, followed by static long range antiferromagnetic order at 127 K. Both the structural distortion and magnetic order are identical to other rare-earth oxypnictides. Electron-doping the system with either Fluorine or oxygen deficiency suppresses the structural distortion and static long range antiferromagnetic order, therefore placing these materials into the same class of FeAs-based superconductors.

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

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 4150-4153
description: When PV modules are linked to arrays, the resulting array power is lower than the sum of the power of
each PV module. This effect is called mismatch loss. It has been studied on crystalline PV modules before, especially
concerning shading effects [1, 2], measures of control and reduction [4, 5] and in large-scale photovoltaic generators
[3]. Though, these former investigations deal with crystalline PV modules. Due to the increasing number of thin film
modules, the actual mismatch losses of thin film arrays are of great importance for the cost effectiveness study,
quality control and plant layout. Therefore mismatch losses of thin film modules have been studied and the results
have been analyzed as a function of characteristic scatterings. Monte Carlo techniques have been used to select
random IV-curves and combine them to arrays. Mismatch losses have been determined for different configurations in
relation to their characteristic scatterings. The results of the simulation have been validated and reconstructed by
measurements of real arrays with well known characteristics.

description: We consider a new mechanism for the removal of the angular momentum from an X-ray binary system and the change in its orbital period - the mass loss in the form of a wind from an accretion disc. Both observations and models predict powerful winds from discs in X-ray transients. We have obtained an analytical estimate for the increase in the orbital period of a binary system with a wind from the disc during an outburst, and quantitative estimates are given for the systems XTE J1118+480, A0620-00 and GRS 1124-68. Resulting rate of period grow is of order of the observed rates of secular decrease in the period. We also compare the predicted rate of change in the period of a binary system due to the flow of matter into the disc and outflow from the second Lagrange point with the observations. It is concluded that the above mechanisms cannot explain the observed secular decrease in the period of the three X-ray Novae, and it is necessary to consider a circumbinary disc that drains the binary's angular momentum.

description: We describe a low-cost three-dimensional underwater particle tracking velocimetry system to directly measure particle settling rate and flux in low-turbulence aquatic environments. The system consists of two waterproof cameras that acquire stereoscopic videos of sinking particles at 48 frames s−1 over a tunable sampling volume of about 45 × 25 × 24 cm. A dedicated software package has been developed to allow evaluation of particle velocities, concentration and flux, but also of morphometric parameters such as particle area, sinking angle, shape irregularity, and density. Our method offers several advantages over traditional approaches, like sediment trap or expensive in situ camera systems: (1) it does not require beforehand particle collection and handling; (2) it is not subjected to sediment trap biases from turbulence, horizontal advection, or presence of swimmers, that may alter particulate load and flux; (3) the camera system enables faster data processing and flux computation at higher spatial resolution; (4) apart from the particle settling rates, the particle size distribution, and morphology is determined. We tested the camera system in Lake Stechlin (Germany) in low turbulence and mean flow, and analyzed the morphological properties and settling rates of particles to determine their sinking behavior. The particle flux assessed from conventional sediment trap measurements agreed well with that determined by our system. By this, the low-cost approach demonstrated its reliability in low turbulence environments and a strong potential to provide new insights into particulate carbon transport in aquatic systems. Extension of the method to more turbulent and advective conditions is also discussed.

description: Abstract Vegetation covers on dikes and embankment dams have proven as sustainable and cost-effective surface protection against external erosion caused by hydraulic, mechanical, or climatic impacts. Determination of the hydraulic loads that act upon these covers requires the knowledge of the flow resistance. While the high-velocity flows on vegetated slopes are often aerated, the flow aeration has rarely been considered, and no direct measurements of the air-water flow properties have been conducted to date. The air-water flow properties are needed for a direct estimation of important design parameters such as friction factors and residual head at the downstream end. Herein, unique air-water flow measurements were conducted in high-velocity air-water flows down a vegetated chute with a 1:3 slope. Several vegetation covers were tested for a range of flow rates. The experiments revealed strong flow aeration within three-dimensional, fragmented flows associated with complex interactions of vegetation and high-velocity flows. The air-water flow properties were measured with phase-detection intrusive probes providing novel insights into aerated flows on vegetated chutes including distributions of void fraction, bubble count rate, and interfacial velocity as well as direct estimates of energy dissipation and flow resistance. The results highlighted strong flow aeration and energy dissipation for all vegetated configurations. The median equivalent Darcy-Weisbach friction factors for all vegetations were within 0.19 to 0.45, comparable to aerated flows on stepped spillways. The present results highlighted the significant flow resistance of vegetated covers and the need to consider air-water flow properties in the design of vegetated chutes.
Coupled changes in traits and biomasses cascading through a tritrophic plankton food web
Creators: name: Ehrlich, Elias

Publisher: name: FID GEO
Year: 2020

description: Trait-based approaches have broadened our understanding of how the composition of ecological communities responds to environmental drivers. This research has mainly focussed on abiotic factors and competition determining the community trait distribution, while effects of trophic interactions on trait dynamics, if considered at all, have been studied for two trophic levels at maximum. However, natural food webs are typically at least tritrophic. This enables indirect interactions of traits and biomasses among multiple trophic levels leading to underexplored effects on food web dynamics. Here, we demonstrate the occurrence of mutual trait adjustment among three trophic levels in a natural plankton food web (Lake Constance) and in a corresponding mathematical model. We found highly recurrent seasonal biomass and trait dynamics, where herbivorous zooplankton increased its size, and thus its ability to counter phytoplankton defense, before phytoplankton defense actually increased. This is contrary to predictions from bitrophic systems where counter-defense of the consumer is a reaction to prey defense. In contrast, counter-defense of carnivores by size adjustment followed the defense of herbivores as expected. By combining observations and model simulations, we show how the reversed trait dynamics at the two lower trophic levels result from a “trophic biomass–trait cascade” driven by the carnivores. Trait adjustment between two trophic levels can therefore be altered by biomass or trait changes of adjacent trophic levels. Hence, analyses of only pairwise trait adjustment can be misleading in natural food webs, while multitrophic trait-based approaches capture indirect biomass–trait interactions among multiple trophic levels.

description: Abstract Although the majority of coastal sediments consist of sandy material, in some areas marine ingression caused the submergence of terrestrial carbon-rich peat soils. This affects the coastal carbon balance, as peat represents a potential carbon source. We performed a column experiment to better understand the coupled flow and biogeochemical processes governing carbon transformations in submerged peat under coastal fresh groundwater (GW) discharge and brackish water intrusion. The columns contained naturally layered sediments with and without peat (organic carbon content in peat 39 ± 14 wt%), alternately supplied with oxygen-rich brackish water from above and oxygen-poor, low-saline GW from below. The low-saline GW discharge through the peat significantly increased the release and ascent of dissolved organic carbon (DOC) from the peat (δ13CDOC − 26.9‰ to − 27.7‰), which was accompanied by the production of dissolved inorganic carbon (DIC) and emission of carbon dioxide (CO2), implying DOC mineralization. Oxygen respiration, sulfate (SO42−) reduction, and methane (CH4) formation were differently pronounced in the sediments and were accompanied with higher microbial abundances in peat compared to sand with SO42−-reducing bacteria clearly dominating methanogens. With decreasing salinity and SO42− concentrations, CH4 emission rates increased from 16.5 to 77.3 μmol m−2 d−1 during a 14-day, low-saline GW discharge phase. In contrast, oxygenated brackish water intrusion resulted in lower DOC and DIC pore water concentrations and significantly lower CH4 and CO2 emissions. Our study illustrates the strong dependence of carbon cycling in shallow coastal areas with submerged peat deposits on the flow and mixing dynamics within the subterranean estuary.

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1368-1372
description: 120 μm thick multicrystalline Si solar cells with SiO/SiN stack rear-side passivation and Al point contacts are locally characterized using the CELLO technique. By combining different standard measurement modes—e.g. using different laser wavelengths, variation of global illumination intensity, and by measuring at
different points along the I-V curve—effects due to parasitic shunting can be separated from other rear side effects like inhomogeneous surface passivation (i.e. due to stack or contacts) or series resistance. An increased series resistance at the rear side is found to improve the rear surface recombination behavior and thus induces a boost in the photocurrent response as an unexpected seemingly positive side effect. As a consequence the series resistance distribution of the rear side has to be taken into account for the correct interpretation of photocurrent data measured using light with long wavelengths.

The analysis technique is described in detail. The ridge particles, observed at large $Δη$ in dihadron correlations in central Au+Au collisions, appear to be uniformly distributed over the measured $Δη$-$Δη$ region in 3-particle correlation. The results, together with theoretical models, should help further our understanding of the underlying physics of the ridge.

description: We measured the lifetime and the mesonic and non-mesonic decay rates of the 4He-Lambda hypernucleus. The hypernuclei were created using a 750 MeV/c momentum K- beam on a liquid 4He target by the reaction 4He(K-,pi-)4He-Lambda. The 4He-Lambda lifetime was directly measured using protons from Lambda p -> n p non-mesonic decay (also referred to as proton-stimulated decay) and was found to have a value of tau = 245 +/- 24 ps. The mesonic decay rates were determined from the observed numbers of pi-'s and pi0's as Gamma_pi-/Gamma_tot = 0.270 +/- 0.024 and Gamma_pi0/Gamma_tot = 0.564 +/- 0.036, respectively, and the values of the proton- and neutron-stimulated decay rates were extracted as Gamma_p/Gamma_tot = 0.169 +/- 0.019 and Gamma_n/Gamma_tot <= 0.032 (95% CL), respectively. The effects of final-state interactions and possible 3-body Lambda N N decay contributions were studied in the context of a simple model of nucleon-stimulated decay. Nucleon-nucleon coincidence events were observed and were used in the determination of the non-mesonic branching fractions. The implications of the results of this analysis were considered for the empirical Delta I = 1/2 rule and the decay rates of the 4H-Lambda hypernucleus.

description: Periphytic biofilms are the major resource for many herbivorous invertebrates in both marine and freshwater benthos. They are of crucial importance for benthic food webs, substrate stability, and biogeochemical processes in littoral zones. While the importance of invertebrate grazing on biofilms has been studied extensively using natural, mixed algal communities grown on artificial substrates, there is so far no method available to create defined periphyton communities for these grazing studies. The reason for this is that many benthic algae interact with co-occurring species within the extracellular polymeric substances (EPSs) that form the nonorganismic part of the biofilm. Here, we present a novel method that allows the manufacturing of defined monoculture and multispecies biofilms by using an alginate polymer as artificial EPS structure, into which algal cultures can be embedded. Using confocal laser scanning microscopy, we show that alginate effectively embeds various algal taxa in an EPS matrix that is very similar to natural biofilms. In a grazing experiment, we demonstrate that several common freshwater herbivorous invertebrates can graze these alginate biofilms efficiently. As the method is easy to handle, it allows for highly controlled feeding experiments with benthic herbivores to assess, for example, the role of algal biodiversity on the efficiency of top-down control, the effects of environmental drivers such as nutrients, salinity, or seawater acidification on biofilm community structure, and the impacts of herbivory in benthic communities.

description: This paper considers a Markov decision model for profit maximization of a cloud computing service provider catering to customers submitting jobs with firm real-time random deadlines. Customers are charged on a per-job basis, receiving a full refund if deadlines are missed. The service provider leases computing resources from an infrastructure provider in a two-tier scheme: long-term leasing of basic infrastructure, consisting of heterogeneous parallel service nodes, each modeled as a multi-server queue, and short-term leasing of external servers. Given the intractability of computing an optimal dynamic resource allocation and job routing policy, maximizing the long-run average profit rate, the paper addresses the design, implementation and testing of low-complexity heuristics. The policies considered are a static policy given by an optimal Bernoulli splitting, and three dynamic index policies based on different index definitions: individually optimal (IO), policy improvement (PI) and restless bandit (RB) indices. The paper shows how to implement efficiently each such policy, and presents a comprehensive empirical comparison, drawing qualitative insights on their strengths and weaknesses, and benchmarking their performance in an extensive study.

Soviet perceptions of the correlation of forces
Creators: name: Nadkarni, Vidya
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines evolving Soviet perspectives on the "correlation of forces" between the socialist world and the capitalist countries in general and the Soviet Union and the United States in particular. The focus is on the Khrushchev and Brezhnev phases of Soviet history. The term "correlation of forces" is primarily an analytic concept used by Soviet leaders and scholars to understand and interpret the pace of what they view as the inevitable historical development in favor of socialism. A rough Soviet equivalent of the Western concept of the "balance of power," "correlation of forces" as it is used by Soviet spokesmen encompasses economic, political, and military-security dimensions. The methodology employed in the thesis in charting the chronological evolution of Soviet thinking regarding the correlation of forces consists of a careful and discriminating textual analysis of terminological variations in Soviet scholarly and official use of the concept over time, with due regard to contextual fluctuations in the domestic and international realms. For its source material, this study relied heavily on the speeches and writing of Soviet leaders as well as utilizing analyses of international developments published in Soviet scholarly journals. The differing stress on each of the three aspects of the correlation of forces—economic, political, and military—between the Khrushchev and Brezhnev periods allowed us to trace the change and evolution of the Soviet world view from a primary stress on economic factors of the distribution of power under Khrushchev, to an emphasis on the military dimension of the balance under Brezhnev. By monitoring terminological variations in the concept, we were able to identify periods of optimism and pessimism during both the Khrushchev and Brezhnev phases. We also noted the important role played by the divergent personalities of Khrushchev and Brezhnev on Soviet portrayal of the correlation of forces. Whereas the exuberant Soviet optimism in the military area lacked any basis in fact under Khrushchev, the depiction of the military correlation, while more muted under Brezhnev, was solidly based. These and other such differences, we argued, were a function of the stamp superimposed on Soviet politics by the respective leaders of the time. This study will, by clarifying the context within which the Soviet leadership makes its choices, contribute to an enhanced understanding of the general foreign policy trends of the USSR.
The structure of the X(3872) as explained by a Diffusion Monte Carlo calculation

description: Two decades after its unexpected discovery, the properties of the $X(3872)$ exotic resonance are still under intense scrutiny. In particular, there are doubts about its nature as an ensemble of mesons or having any other internal structure. We use a Diffusion Monte Carlo method to solve the many-body Schrödinger equation that describes this state as a $c \bar c n \bar n$ ($n=u$ or $d$ quark) system. This approach accounts for multi-particle correlations in physical observables avoiding the usual quark-clustering assumed in other theoretical techniques. The most general and accepted pairwise Coulomb$\,+\,$linear-confining$\,+\,$hyperfine spin-spin interaction, with parameters obtained by a simultaneous fit of around 100 masses of mesons and baryons, is used. The $X(3872)$ contains light quarks whose masses are given by the mechanism responsible of the dynamical breaking of chiral symmetry. The same mechanisms gives rise to Goldstone-boson exchange interactions between quarks that have been fixed in the last 10-20 years reproducing hadron, hadron-hadron and multiquark phenomenology. It appears that a meson-meson molecular configuration is preferred but, contrary to the usual assumption of $D^0\bar{D}^{\ast0}$ molecule for the $X(3872)$, our formalism produces $ωJ/ψ$ and $ρJ/ψ$ clusters as the most stable ones, which could explain in a natural way all the observed features of the $X(3872)$.

El objetivo del monitoreo fue observar el cumplimiento de las leyes de paridad - la nacional y las provinciales - , es decir, que las listas partidarias estén integradas por 50% de mujeres y 50% de varones.
Asimismo, se relevó otro de los requisitos de cumplimiento: la alternancia desde el primer/a candidato/a titular hasta el último suplente. También se monitoreó la presencia de mujeres encabezando las listas, que si bien no es un requisito establecido por ley, constituye un símbolo en relación al cambio cultural que se espera de este tipo de
legislación.

El monitoreo dio cuenta de un alto nivel de cumplimiento de la ley de paridad nacional y las leyes homólogas provinciales. Respecto al encabezamiento de las listas, para ambas categorías nacionales se observa un aumento de las listas encabezadas por mujeres, más drástico para el caso de la Cámara Baja que aumentó 13 puntos porcentuales respecto al 2019.

A nivel provincial, los hallazgos son similares: alto porcentaje de cumplimiento de la paridad o cupo (Corrientes) y encabezamientos de mujeres que se ubican entre el 26.5% en promedio para senadores/as provinciales y el 33,3% en promedio para diputados/as provinciales. Destaca el caso de San Luis que en su primera (2021) y segunda (2023) aplicación de la ley de paridad todas las listas de candidatos/as a la Cámara de Diputados/as deben estar encabezadas por una mujer (Ley Nº 1038/2020).

all individual amorphous silicon layers are controlled by a thorough in- and off-line metrology system. Process
optimization thanks to improved process control has led to higher stabilized efficiency of our single junction
amorphous silicon modules (from 6.2% average production efficiency to the current 7.25%) while narrowing the
production efficiency dispersion, allowing an increase in the factory throughput and reducing the amount of poorly
performing modules manufactured to a bare minimum (0.12%). Additionally, the highest stabilized efficiency
achieved so far in R&D full size (5.72 m2) modules is 7.95%.

description: Taking the site-diagonal terms of the one-dimensional ionic Hubbard model (IHM) as $H_0$, we employ Continuous Unitary Transformations (CUT) to obtain a "classical" effective Hamiltonian in which hopping term has been integrated out. For this Hamiltonian spin gap and charge gap are calculated at half-filling and subject to periodic boundary conditions. Our calculations indicate two transition points. In fixed $Δ$, as $U$ increases from zero, there is a region in which both spin gap and charge gap are positive and identical; characteristic of band insulators. Upon further increasing $U$, first transition occurs at $U=U_{c_{1}}$, where spin and charge gaps both vanish and remain zero up to $U=U_{c_{2}}$. A gap-less state in charge and spin sectors characterizes a metal. For $U>U_{c_{2}}$ spin gap remains zero and charge gap becomes positive. This third region corresponds to a Mott insulator in which charge excitations are gaped, while spin excitations remain gap-less.

description: In this paper we study the global dynamics of the inverted spherical pendulum with a vertically vibrating suspension point in the presence of an external horizontal periodic force field. We do not assume that this force field is weak or rapidly oscillating. We prove that there always exists a non-falling periodic solution, i.e., there exists an initial condition such that the rod of the pendulum never becomes horizontal along the corresponding solution. We also show numerically that there exists an asymptotically stable non-falling solution for a wide range of parameters of the system.

description: Using a nonlocal field transformation for the gauge field known as Cho--Faddeev--Niemi--Shabanov decomposition as well as ideas taken from generalized integrability, we derive a new family of infinitely many conserved currents in the self-dual sector of SU(2) Yang-Mills theory. These currents may be related to the area preserving diffeomorphisms on the reduced target space. The calculations are performed in a completely covariant manner and, therefore, can be applied to the self-dual equations in any space-time dimension with arbitrary signature.

description: It is well known that the natural seasonal and daily changes in ambient temperature, intensity and
spectral distribution of irradiance and the angle of incidence between the sun and the PV array affect the PV module’s
behavior. This paper focuses on the investigation of the outdoor temperature coefficient (TCo) of the maximum
power (Pmax) (DC values) - here  - of various PV technologies with respect to location and season. The chosen
locations are Northern Italy (Milano), Southern Italy (Catania) and the Italian Alps (Bolzano). The results
demonstrate variations of the power TCo during three seasons – spring, summer and autumn – for four different
irradiance levels (300, 500, 700, 900 W/m2). The obtained results show that three groups according to module
technologies with a similar behavior can be formed for the three locations. For the plants in Bolzano and Catania the
groups are (1) mc-Si, pc-Si and HIT crystalline module technologies, (2) CdTe and CIGS and (3) amorphous silicon
technologies. For Milano, the groups are (1) HIT, CdTe and CIS, (2) mc-Si and pc-Si and (3) a-Si modules.

description: We study the longitudinal dynamical structure factor $S^{zz}(q,ω)$ for the anisotropic spin-1/2 (XXZ) chain at finite magnetic field using bosonization. The leading irrelevant operators in the effective bosonic model stemming from band curvature describe boson decay processes and lead to a high-frequency tail and a finite width $γ_q$ of the on-shell peak for $S^{zz}(q,ω)$. We use the Bethe ansatz to show that $γ_q\sim q^2$ for $q\ll 1$ and to calculate the amplitudes of the leading irrelevant operators in the effective field theory.

Chai Dhaba to Cafe: A Study of Cultural Commodification and Socio-spatial Politics in Pakistani Upscaled Dhabas
Creators: name: Huss
Publisher: name: University of Chicago
Year: 2021
Subjects: subject: Pakistan+chat dhabas

description: The chai dhaba has long existed in the history of the sub-continent, as an open air road-side set-up for tea and parathas. However, over the past decade, cities in Pakistan have seen an upsurge in the upscaled chai dhaba or chai cafe culture. Most of these new inventions name themselves in a similar fashion to conventional chai dhabas but may attach “Studio”, “Cafe”to their label. Through this study, I will show how these new spaces romanticize rural aesthetics and minority communities vis-a-vis packaging them in a wide offering of tea, food and recreation. I analyze their claim to draw upon tradition and thus aim to see the spatial dynamics of modern dhabas, the extent to which they work to appropriate working-class culture and the overall basis on which they market their appeal. Consequently, I will dissect the socio-cultural framing of this space to analyze what audiences these dhabas target, in order to understand whether they allow room for social inclusion, specifically through the lens of class and gender.

description: Multifunctional PECVD layers, which can be used as dopant source, surface passivation, anti-reflection
coating, and isolation layer, can significantly simplify high-efficiency industrial solar cell production. A proof of concept
for the production of Passivated Emitter and Rear Totally diffused (PERT) solar cells has recently been presented
resulting in a peak efficiency of 18.3 %. In this work we want to enlighten the economical aspect of the extremely simple
production of PERT cells, which will be called the X-PERT approach in the following. Based on detailed Cost of
Ownership (COO) calculations, it will be shown that by the consequent use of the multifunctional PECVD layers it is
possible to reduce the levelized costs of electricity (LCOE) by 0.6 €ct/kWh. A possibility to further improve the X-PERT
approach to a bifacial solar cell will even further simplify the process and drastically reduce the LCOE by 1.0 €ct/kWh.

description: The post-breakage-integrity of BIPV module is the one of the most critical measurement for the approval of the use of
BIPV module in buildings; especially for overhead-glazing application. Up to now, only laminated glass with PVBinterlayer
is accepted as laminated safety glass in a regulated building product list. With respect to higher operating
temperature and alternative interlayer materials used in PV laminated glass (BIPV-modules), therefore, the mechanical
behaviours of PV laminated glass will be changed compared to conventional laminated glass. The aim of this paper is to
examine post-breakage-integrity behaviour of eleven BIPV modules with different module configurations; glass types,
operating temperatures, interlayer types of EVA and PVB, with- and without solar cells, interlayer thickness and glass
thickness.
For the test procedure, the PV module was damaged by striking with external mechanical load. The applied load and load
duration are 500 N/m² over 24 hours by flexible sand bags. A 2-side standard-conform line mounting was used. Due to
different fracture behaviour of BIPV-laminated glass modules, two identical modules have been investigated in parallel.
At room temperature, all specimens pass the test. Even PV module with glass-backsheet configuration is not allowed to
be employed in overhead-glazing applications, it also passes the test. The glass configuration of heat-strengthened glass
(TVG) has better behaviours compared to tempered safety glass (ESG), which is also in a good agreement with the
regulation of DIN 18008. At high temperature, the trend of the results becomes negative compared to those at room
temperature. There is no difference between EVA and PVB interlayers in PV modules without solar cell. The solar cells
with certain interlayers could have a positive result. PV modules with thinner glass thickness could also pass the test,
even though the stiffness of thinner laminated glasses is lower compared to that of thicker laminated glass.
One-dimensional extended Hubbard model in the atomic limit

description: We present the exact solution of the one-dimensional extended Hubbard model in the atomic limit within the Green's function and equation of motion formalism. We provide a comprehensive and systematic analysis of the model by considering all the relevant response and correlation functions as well as thermodynamic quantities in the whole parameter space. At zero temperature we identify four phases in the plane (U,n) [U is the onsite potential and n is the filling] and relative phase transitions as well as different types of charge ordering. These features are endorsed by investigating at T=0 the chemical potential and pertinent local correlators, the particle and double occupancy correlation functions, the entropy, and by studying the behavior in the limit T going to zero of the charge and spin susceptibilities. A detailed study of the thermodynamic quantities is also presented at finite temperature. This study evidences that a finite-range order persists for a wide range of the temperature, as shown by the behavior of the correlation functions and by the two-peak structure exhibited by the charge susceptibility and by the entropy. Moreover, the equation of motion formalism, together with the use of composite operators, allows us to exactly determine the set of elementary excitations. As a result, the density of states can be determined exactly and a detailed analysis of the specific heat allows for identifying the excitations and for ascribing its two-peak structure to a redistribution of the charge density.

description: Understanding the intricate relationship between atomic structure and ion motion is crucial for optimizing the performance of battery materials. This thesis aims to explore this theme through a series of comprehensive studies. Investigations are performed via in situ XRD into the synthesis pathways and challenges for antiperovskite materials, shedding light on how specific structural arrangements and the formation of solid solutions influence ionic mobility. The potential of multivalent spinel oxides, particularly magnesium-based materials, is examined for rechargeable battery cathodes. Through structural modifications such as metal doping and cation inversion, the critical role of local structural features in determining bulk properties is revealed. Additionally, we evaluate the significance of disorder within solid electrolytes, with a focus on the paddlewheel effect observed in the ion transport mechanisms. Using experimental techniques such as neutron and x-ray diffraction and pair distribution function, and computational methods like reverse Monte Carlo profiling and AIMD, this research explores disorder within polyanion groups and sodium cation transport pathways. Our findings shed light on the interplay between static and dynamic disorder, offering valuable insights into the mechanisms governing ion dynamics and solid-state electrolyte functionality. Overall, this thesis underscores the importance of understanding atomic structure for elucidating ion motion in battery materials, providing crucial insights for the development of more efficient energy storage systems.
