Subjects: subject: Quantum Physics (quant-ph)

description: We present a protocol for sending a message over a quantum channel with different layers of security that will prevent an eavesdropper from deciphering the message without being detected. The protocol has two versions where the bits are encoded in either pairs of entangled photons or separate photons. Unlike many other protocols, it requires a one-way, rather than a two-way, quantum channel and does not require a quantum memor. A quantum key is used to encrypt the message and both the key and the message are sent over the quantum channle with the same quantum encoding technique. The key is sent only if no eavesdropper is detected.

description: In this paper we relate the Fefferman-Graham ambient metric construction for conformal manifolds to the approach to conformal geometry via the canonical Cartan connection. We show that from any ambient metric that satisfies a weakening of the usual normalisation condition, one can construct the conformal standard tractor bundle and the normal standard tractor connection, which are equivalent to the Cartan bundle and the Cartan connection. This result is applied to obtain a procedure to get tractor formulae for all conformal invariants that can be obtained from the ambient metric construction. We also get information on ambient metrics which are Ricci flat to higher order than guaranteed by the results of Fefferman-Graham.

description: We study the problem of learning-augmented predictive linear quadratic control. Our goal is to design a controller that balances \textit{"consistency"}, which measures the competitive ratio when predictions are accurate, and \textit{"robustness"}, which bounds the competitive ratio when predictions are inaccurate. We propose a novel $λ$-confident policy and provide a competitive ratio upper bound that depends on a trust parameter $λ\in [0,1]$ set based on the confidence in the predictions and some prediction error $\varepsilon$. Motivated by online learning methods, we design a self-tuning policy that adaptively learns the trust parameter $λ$ with a competitive ratio that depends on $\varepsilon$ and the variation of system perturbations and predictions. We show that its competitive ratio is bounded from above by $ 1+{O(\varepsilon)}/({Θ(1)+Θ(\varepsilon)})+O(μ_{\mathsf{Var}})$ where $μ_\mathsf{Var}$ measures the variation of perturbations and predictions. It implies that when the variations of perturbations and predictions are small, by automatically adjusting the trust parameter online, the self-tuning scheme ensures a competitive ratio that does not scale up with the prediction error $\varepsilon$.

description: Extensive electromagnetic (EMAG) studies are necessary to fully realize the potential of axial flux machines (AFMs). However, the disc-shaped air gap and the complex three-dimensional path of magnetic flux pose challenges in modelling AFMs compared to conventional radial flux machines. This study reviews current research on EMAG modelling and simulation of AFMs, highlighting the need for tools that address AFM-specific effects. Existing approaches are analysed based on the requirements composed by fundamental objectives of EMAG simulations and AFM-specific effects, revealing limitations in flexibility and the ability to capture emerging trends in the field of AFMs. While computationally expensive 3D finite element analysis (FEA) offers comprehensive flexibility in EMAG modelling, it lacks efficiency to carry out extensive studies on such trends. Therefore, there is a need to either further accelerate 3D FEA or to increase the flexibility of existing alternatives to facilitate and thereby promote research in the field of AFM and other 3D flux machines. While the integration of some production-specific effects, such as manufacturing tolerances, already is investigated for EMAG simulations of AFMs the future research on the early estimation of manufacturability based on EMAG simulations is crucial for evaluating designs and anticipating manufacturing influences.

description: Bayesian model selection objectively ranks competing models by computing Bayesian Model Evidence (BME) against test data. BME is the likelihood of data to occur under each model, averaged over uncertain parameters. Computing BME can be problematic: exact analytical solutions require strong assumptions; mathematical approximations (information criteria) are often strongly biased; assumption-free numerical methods (like Monte Carlo) are computationally impossible if the data set is large, for example like high-resolution snapshots from experimental movies. To use BME as ranking criterion in such cases, we develop the “Method of Forced Probabilities (MFP)”. MFP swaps the direction of evaluation: instead of comparing thousands of model runs on random model realizations with the observed movie snapshots, we force models to reproduce the data in each time step and record the individual probabilities of the model following these exact transitions. MFP is fast and accurate for models that fulfil the Markov property in time, paired with high-quality data sets that resolve all individual events. We demonstrate our approach on stochastic macro-invasion percolation models that simulate gas migration in porous media, and list additional examples of probable applications. The corresponding experimental movie was obtained from slow gas injection into water-saturated, homogeneous sand in a 25 x 25 x 1 cm acrylic glass tank. Despite the movie not always satisfying the high demands (resolving all individual events), we can apply MFP by suggesting a few workarounds. Results confirm that the proposed method can compute BME in previously unfeasible scenarios, facilitating a ranking among competing model versions for future model improvement.

We report the antiferromagnetic (AFM) propagation vectors, magnetic transition temperatures, and the ordered magnetic moments. We find a nonmonotonic change of the AFM propagation vector with $x$, with a minimum occurring at the tetragonal to collapsed-tetragonal phase crossover. For $x=0.10$ and $0.82$ we find $c$-axis helix ordering of the Eu magnetic moments (spins) similar to $x=0$ and $1$, with the spins oriented within the $ab$-plane. For $x=0.20$ and $0.42$ we find higher-temperature $c$-axis FM order and lower-temperature $c$-axis cone order. Using the extinction conditions for the space group, we discovered that the Eu spins are ordered in the higher-temperature $c$-axis FM phase for intermediate values of $x$, contrary to a previous report suggesting only Co/Ni spin ordering. Although we cannot directly confirm that the Co/Ni spins are also ordered, we suggest that $c$-axis itinerant-FM ordering of the Co/Ni spins could provide a molecular field that drives FM ordering of the Eu spins, which in turn provides the anisotropy for the lower-temperature $c$-axis cone order.

description: Monsters lurk within mathematical as well as literary haunts. I propose to trace some pathways between these two monstrous habitats. I start from Jeffrey Jerome Cohen's influential account of monster culture and explore how well mathematical monsters fit each of his seven theses. The mathematical monsters I discuss are drawn primarily from three distinct but overlapping domains. Firstly, late nineteenth-century mathematicians made numerous unsettling discoveries that threatened their understanding of their own discipline and challenged their intuitions. The great French mathematician Henri Poincaré characterised these anomalies as `monsters', a name that stuck. Secondly, the twentieth-century philosopher Imre Lakatos composed a seminal work on the nature of mathematical proof, in which monsters play a conspicuous role. Lakatos coined such terms as `monster-barring' and `monster-adjusting' to describe strategies for dealing with entities whose properties seem to falsify a conjecture. Thirdly, and most recently, mathematicians dubbed the largest of the sporadic groups `the Monster', because of its vast size and uncanny properties, and because its existence was suspected long before it could be confirmed.

description: Magnetic and topological properties along with quantum correlations in terms of several entanglement measures have been investigated for an antiferromagnetic spin-1/2 XY model in the presence of transverse magnetic field and XZX$-$YZY type of three-spin interactions. Symmetries of the spin Hamiltonian have been identified. Under the Jordan-Wigner transformation, the spin Hamiltonian converted into spinless superconducting model with nearest neighbor hopping and Cooper pairing terms in addition to next nearest neighbor Cooper pairing potential. Long range antiferromagnetic order has been studied in terms of staggered spin-spin correlation functions, while the topological orders have been characterized by winding numbers. Magnetic and topological phase diagrams have been prepared. Faithful coexistence of magnetic and topological superconducting phases is found in the entire parameter regime. Boundaries of various quantum phases have been marked and positions of bicritical points have been identified.

description: Reconfigurable Scan Networks (RSNs) are widely used for accessing instruments offline during debug, test and validation, as well as for performing system-level-test and online system health monitoring. The correct operation of RSNs is essential, and RSNs have to be thoroughly tested. However, due to their inherently sequential structure and complex control dependencies, large parts of RSNs have limited observability and controllability. As a result, certain faults at the interfaces to the instruments, control primitives and scan segments remain undetected by existing test methods. In the paper at hand, Design-for-test (DfT) schemes are developed to overcome the testability problems e.g. by resynthesizing the initial design. A DfT scheme for RSNs is presented, which allows detecting all single stuck-at-faults in RSNs by using existing test generation techniques. The developed scheme analyzes and ensures the testability of all parts of RSNs, which include scan segments, control primitives, and interfaces to the instruments. Therefore, the developed scheme is referred to as a complete DfT scheme . It allows for a test integration to cover multiple fault locations can with a single efficient test sequence and to reduce overall test cost.

Expansion of a filtration with a stochastic process: a high frequency trading perspective

Year: 2017
Subjects: subject: Statistics
subject: FOS: Mathematics

description: A theory of expansion of filtrations has been developed since the 1970s to model dynamic probabilistic problems with asymmetric information. It has found a special echo in mathematical finance around the concept of insider trading, which has appeared in return very convenient for expressing the abstract properties of augmentations of filtrations. Research has historically focused on two particular classes of expansions, initial and progressive expansions, corresponding to additional information generated respectively by a random variable and a random time. Although they can reproduce some stylized facts in the insider trading paradigm, those two types of expansions are too restrictive to model quantitatively dynamic phenomenons of contemporary interest such as the topical high-frequency trading. In order to model such a continuous flow of information Kchia and Protter (2015) introduce augmentations of filtrations where the additional information is generated by a stochastic process.
      This thesis complements the pioneering work of Kchia and Protter (2015) with an analysis of the information drift appearing in the transformation of semimartingales, which leads to a quantitative valuation of the additional information. In the preliminary chapters we introduce the general framework of expansions of filtrations and present the information drift as a key proxy to the value of information by characterizing its existence as a no-arbitrage condition and expressing problems the value increase of optimization problems associated with additional information as one of its integrals. The theoretical core of this thesis is formed by two series of convergence theorems for semimartingales and their information drifts under a new topology on filtrations, from which we derive the transformation of semimartingales when the filtration is augmented with a stochastic process as well as a computational method to estimate the information drift. We finally study several dynamical examples of anticipative expansions of a Brownian filtration with stochastic processes, where the information drift does or does not exist, and set the foundations for an ongoing application to estimating the advantage of high-frequency traders on the general market.

Two-Dimensional Thouless Pumping of Ultracold Fermions in Obliquely Introduced Optical Superlattice

description: We propose a two-dimensional (2D) version of Thouless pumping that can be realized by using ultracold atoms in optical lattices. To be specific, we consider a 2D square lattice tight-binding model with an obliquely introduced superlattice. It is demonstrated that quantized particle transport occurs in this system, and that the transport is expressed as a solution of a Diophantine equation. This topological nature can be understood by mapping the Hamiltonian to a three-dimensional (3D) cubic lattice model with a homogeneous magnetic field. We also propose a continuum model with obliquely introduced superlattice and obtain the amount of pumping by calculating the Berry curvature. For this model, the same Diophantine equation can be derived from the plane-wave approximation. Furthermore, we investigate the effect of a harmonic trap by solving the time-dependent Schrödinger equation. Under a harmonic trap potential, as often used in cold atom experiments, we show, by numerical simulations, that nearly quantized pumping occurs when the phase of the superlattice potential is driven at a moderate speed. Also, we find that two regions appear, the Hofstadter region and the rectifying region, depending on the modulation amplitude of the superlattice potential. In the rectifying region with larger modulation amplitudes, we uncover that the pumping direction is restricted to exactly the $x$-axis or the $y$-axis direction. This difference in these two regions causes a crossover behavior, characterizing the effect of the harmonic trap.

description: Jacobi algebroids (i.e. `Jacobi versions' of Lie algebroids) are studied in the context of graded Jacobi brackets on graded commutative algebras. This unifies varios concepts of graded Lie structures in geometry and physics. A method of describing such structures by classical Lie algebroids via certain gauging (in the spirit of E.Witten's gauging of exterior derivative) is developed. One constructs a corresponding Cartan differential calculus (graded commutative one) in a natural manner. This, in turn, gives canonical generating operators for triangular Jacobi algebroids. One gets, in particular, the Lichnerowicz-Jacobi homology operators associated with classical Jacobi structures. Courant-Jacobi brackets are obtained in a similar way and use to define an abstract notion of a Courant-Jacobi algebroid and Dirac-Jacobi structure. All this offers a new flavour in understanding the Batalin-Vilkovisky formalism.

description: The purpose of this study was to conduct a formal program evaluation of the New York State newborn screening for Krabbe disease (KD), a rare neurological disease with variable onset of symptoms to assess 1) the perceptions of stakeholders 2) KD test characteristics, and 3) actual program costs. Using the CDC Framework for Program Evaluation in Public Health, integration of qualitative and quantitative techniques was used to provide a comprehensive evaluation. Stakeholder input was elicited using semi-structured interviews of medical professionals and parents and content analysis of the interview transcripts identified five themes: Legislative/Political, Unintended Consequences, Knowledge and Science, Communication, and Moral Issues. Finally, cost and charge data were used to calculate the cost of the KD screening program from the perspective of the State. Triangulation of the results provided the conclusions for practice and policy recommendations. Using the data from the State annual reports of 9 positive KD screening results, sensitivity was calculated at 100%, specificity was 99%, positive predictive value was 5%, negative predictive value was 100% and prevalence was 1/100,000 births. However, the State reports did not include the 19 infants with low enzyme activity and mutations that could develop into later onset forms of KD. When these 19 infants were included, sensitivity, specificity, and negative predictive value remained unchanged; however, positive predictive value rose to 15%, and prevalence increased to 3/100,000 births. The total annual cost of the program from the perspective of the State was calculated at $750,652. For parents, the cost calculated from initial newborn screen to neurodiagnostic testing was $2669/family. Since 2006, there have been more than 1,000,000 infants screened for KD in New York State. While the screening has identified four infants with the early infantile form of the disease, there have been 24 others identified with low enzyme activity and mutations that may cause later onset forms of the disease, which are poorly understood. This unexpected finding suggests that newborns may be diagnosed with a disease that may not present symptomatically until adulthood. Unfortunately, the current confirmatory enzyme test and neurodiagnostic tests cannot predict onset of disease or severity of symptoms. In addition, the only available treatment, a cord blood transplant, is irreversible, has a high risk of morbidity and mortality, and long term outcomes have not been studied. While the cost of the program from the perspective of the state is not excessive, cost-effectiveness studies are needed to determine the cost of KD screening from the societal perspective, and should include treatment and follow up costs.

description: The essence of metabolic engineering is the modification of microbes for the overproduction of useful compounds. These cellular factories are increasingly recognized as an environmentally-friendly and cost-effective way to convert inexpensive and renewable feedstocks into products, compared to traditional chemical synthesis from petrochemicals. The products span the spectrum of specialty, fine or bulk chemicals, with uses such as pharmaceuticals, nutraceuticals, flavors and fragrances, agrochemicals, biofuels and building blocks for other compounds. However, the process of metabolic engineering can be long and expensive, primarily due to technological hurdles, our incomplete understanding of biology, as well as redundancies and limitations built into the natural program of living cells. Combinatorial or directed evolution approaches can enable us to make progress even without a full understanding of the cell, and can also lead to the discovery of new knowledge. This thesis is focused on addressing the technological bottlenecks in the directed evolution cycle, specifically de novo DNA assembly to generate strain libraries and small molecule product screens and selections.

description: An ultra-sensitive spectrofluorimetry method was developed and validated for the rapid determination of ferrocyanide ions (hexacyanidoferrate(II), FeCN64-, FCNs) by using sulphur (S) and nitrogen (N) dual-doped fluorescence carbon nanoparticles (S,N-FCNPs) as nanoprobe. The fluorescence of S,N-FCNPs was strongly reduced due to the dynamic interaction between S,N-FCNPs and FeCNs. The developed method proved to be highly sensitive and selective for FeCNs detection with linearity in three concentration ranges over four orders of magnitude, covering 0.01–200.0 μg/mL. A limit of detection (LOD) of 2.8 ng/mL was obtained. The method was successfully applied for the determination of FeCNs in a series of dietary food salt samples and gave satisfactory results; the spiked recoveries were 97.6‒104.6% with standard uncertainty less than 5.8%. The method proved to be applicable for ultra-trace detection of FeCNs in food salt samples, having advantages in great simplicity, rapid response, low cost, favourable selectivity, and high sensitivity.

description: In this paper we study the linear stability of selfinteracting boson stars in the nonrelativistic limit of the Einstein-Klein-Gordon theory. For this purpose, based on a combination of analytic and numerical methods, we determine the behavior of general linear perturbations around the stationary and spherically symmetric solutions of the Gross-Pitaevskii-Poisson system. In particular, we conclude that ground state configurations are linearly stable if the selfinteraction is repulsive, whereas there exist a state of maximum mass that divides the stable and the unstable branches in case the selfinteraction is attractive. Regarding the excited states, they are in general unstable under generic perturbations, although we identify a stability band in the first excited states of the repulsive theory. This result is independent of the mass of the scalar field and the details of the selfinteraction potential, and it is in contrast to the situation of vanishing selfinteraction, in which excited states are always unstable.

description: Im Bauwesen werden Befestigungselemente zur Verbindung von Stahlkonstruktionen mit Betonbauteilen u.a. für Aufzüge, Kranbahnträger und Schwenkkrane oder Maschinen verwendet, bei denen häufig wiederholte Beanspruchungen in Kombination mit einer statisch wirkenden Belastung auftreten, die zu einem Ermüdungsversagen des Befestigungspunkts führen können. Der bisherige Wissensstand zur Ermüdungstragfähigkeit von Befestigungen in Beton basiert im Wesentlichen auf Schwingversuchen im Schwellbereich mit geringer Unterlast, wobei die Versagensart Stahlbruch des Befestigungsmittels häufig maßgebend wird. Bei der Bemessung werden für Befestigungen unter kombinierter Beanspruchung daher sehr konservative Annahmen getroffen, die insbesondere im Hinblick auf die Materialermüdung des Stahls von geltenden Normenregelungen im Bauwesen abweichen und vergleichsweise unwirtschaftliche Ergebnisse liefern. In der vorliegenden Arbeit wurde der Einfluss des statischen Lastniveaus auf das Schädigungsverhalten und die Tragfähigkeit von ermüdungsbeanspruchten Befestigungen bei Stahlversagen systematisch untersucht. Hierzu erfolgten experimentelle Untersuchungen an drei verschiedenen Typen mechanischer Befestigungsmittel aus Kohlenstoffstahl, die durch unterschiedliche Kerbdetails gekennzeichnet sind. Aus den durchgeführten Untersuchungen geht hervor, dass der Einfluss des statischen Lastniveaus auf das Ermüdungsverhalten von Befestigungen von der Art des Befestigungsmittels abhängt und bei der Bemessung nicht generell vernachlässigt werden kann. In den Versuchen hat sich dennoch bestätigt, dass der Lastniveaueinfluss nach den vorliegenden Bemessungsansätzen überschätzt wird und je nach Befestigungsmittel zu unwirtschaftlichen Ergebnissen führen kann. Für die untersuchten Dübel und Kopfbolzen konnte ein ähnliches Ermüdungsverhalten wie bei Schraubenverbindungen im Stahlbau bzw. Kopfbolzendübeln im Verbundbau festgestellt werden. Dadurch ist es möglich, eine Bewertung der Ermüdungstragfähigkeit von Befestigungen auf der Basis des Nennspannungskonzepts vorzunehmen. Auf Grundlage der erzielten Erkenntnisse wird ein neues Bemessungskonzept zur Bestimmung des Ermüdungswiderstandes mit statischen Lastanteilen abgeleitet. Dieses erlaubt, die vorhandenen Tragfähigkeitsreserven von Befestigungen unter kombinierter Beanspruchung bei der Bemessung zu nutzen. Darauf basierend wird ein mehrstufiges Nachweiskonzept vorgestellt, das aus drei verschiedenen Bemessungsverfahren besteht, die einen zunehmenden Grad an Genauigkeit und Komplexität bei der Nachweisführung aufweisen. Dies führt zu einer effizienteren Auslegung von Befestigungen wie auch zu Potentialen bei der Bewertung der Restnutzungsdauer von bestehenden Anschlüssen und liefert damit einen wichtigen Beitrag zur Ressourceneinsparung im Bauwesen.

description: The elastic property of membranes self-assembled from AB diblock and ABA triblock copolymers, as coarse-grained model of lipids and the bolalipids, are studied using the self-consistent field theory (SCFT). Specifically, solutions of the SCFT equations, corresponding to membranes in different geometries (planar, cylindrical, spherical, and pore) have been obtained for a model system composed of amphiphilic AB diblock copolymers and ABA triblock copolymers dissolved in A homopolymers. The free energy of the membranes with different geometries is then used to extract the bending modulus, Gaussian modulus, and line tension of the membranes. The results reveal that the bending modulus of the triblock membrane is greater than that of the diblock membrane. Furthermore, the Gaussian modulus and line tension of the triblock membrane indicate that the triblock membranes have higher pore formation energy than that of the diblock membranes. The equilibrium bridging and looping fractions of the triblock copolymers are also obtained. Implications of the theoretical results on the elastic properties of biologically equivalent lipid bilayers and the bolalipid membranes are discussed.

description: The human brain exhibits robustness against natural variability occurring in face images, yet the commonly attempted algorithms for face recognition are not modular and do not apply the principle of binary decisions made by the firing of neurons. This thesis presents a memory based face recognition method based on the concepts of local binary decisions and spatial change features. Local binary decisions are inspired from the binary conversions done by firing of neurons while spatial change features are inspired from the retinal processing of the human visual system. Applying these principles and by using the principle of modularity in a hierarchical manner, a class of memory based face recognition algorithms is formed. These algorithms when applied to difficult testing conditions show high recognition performance. This high recognition performance is enabled by (1) local binary decisions and (2) spatial change detection. The baseline algorithm formed by using these two concepts is called local binary decisions on similarity (LBDS) algorithm. An analysis is performed using the LBDS algorithm to optimize the parameters, and to study the relative effect of spatial change features, local binary decisions, normalization of features, normalization of similarity measure, use of color, localization error compensation and resolution on recognition performance. From the insights gained through the analysis, the LBDS algorithm is further improved by incorporating various preprocessing spatial filter operations to extract more spatial information. The inclusion of preprocessing step helps to achieve even higher recognition performance and robustness to difficult tasks. This improved algorithm is called enhanced local binary decisions on similarity (ELBDS) algorithm. The ELBDS algorithm is further used to incorporate the multiple training images per person in the gallery, and is called an exemplar based face recognition method. The following is the overall recognition performance when using single gallery image per person: 97% on AR, 100% on YALE, 97% on EYALE , 97% on CALTECH, 98% on FERET(FaFb), 94% on FERET(FaFc), 74% on FERET (FaDup1) and 76% on FERET(FaDup2). When using multiple training samples per person, following recognition accuracies are achieved, 99.0% on AR, 99.5% on FERET, 99.5% on ORL, 99.3% on EYALE, 100.0% on YALE and 100.0% on CALTECH face databases.

description: For safe operation, autonomous vehicles have to obey traffic rules that are set forth in legal documents formulated in natural language. Temporal logic is a suitable concept to formalize such traffic rules. Still, temporal logic rules often result in constraints that are hard to solve using optimization-based motion planners. Reinforcement learning (RL) is a promising method to find motion plans for autonomous vehicles. However, vanilla RL algorithms are based on random exploration and do not automatically comply with traffic rules. Our approach accomplishes guaranteed rule-compliance by integrating temporal logic specifications into RL. Specifically, we consider the application of vessels on the open sea, which must adhere to the Convention on the International Regulations for Preventing Collisions at Sea (COLREGS). To efficiently synthesize rule-compliant actions, we combine predicates based on set-based prediction with a statechart representing our formalized rules and their priorities. Action masking then restricts the RL agent to this set of verified rule-compliant actions. In numerical evaluations on critical maritime traffic situations, our agent always complies with the formalized legal rules and never collides while achieving a high goal-reaching rate during training and deployment. In contrast, vanilla and traffic rule-informed RL agents frequently violate traffic rules and collide even after training.

description: In "Mordell-Lang plus Bogomolov", we formulated a conjecture combining the Mordell-Lang conjecture (now proven) and the Bogomolov conjecture, and proved the Mordellic part when A is almost split (i.e., isogenous to the product of an abelian variety and a torus). Here we prove that the full conjecture would follow from the Bogomolov conjecture and an equidistribution result for general semiabelian varieties. These assumptions have been proved when A is almost split, so the conjecture is completely proven in that case.

description: Negative thermal expansion (NTE) - the phenomenon where some materials shrink rather than expand when heated - is both intriguing and useful, but remains poorly understood. Current understanding hinges on the role of specific vibrational modes, but in fact thermal expansion is a weighted sum of contributions from every possible mode. Here we overcome this difficulty by deriving a real-space model of atomic motion in the prototypical NTE material scandium trifluoride, ScF3, from total neutron scattering data. We show that NTE in this material depends not only on rigid unit modes - the vibrations in which the scandium coordination octahedra remain undistorted - but also on modes that distort these octahedra. Furthermore, in contrast with previous predictions, we show that the quasiharmonic approximation coupled with renormalisation through anharmonic interactions describes this behaviour well. Our results point the way towards a new understanding of how NTE is manifested in real materials.
