description: The production of science-ready data from major solar telescopes requires expertise beyond that of the typical observer. This is a consequence of the increasing complexity of instruments and observing sequences, which require calibrations and corrections for instrumental and seeing effects that are not only difficult to measure, but are also coupled in ways that require careful analysis in the design of the correction procedures. Modern space-based telescopes have data-processing pipelines capable of routinely producing well-characterized data products. High-resolution imaging spectropolarimeters at ground-based telescopes need similar data pipelines. We present new methods for flat-fielding spectropolarimetric data acquired with telecentric Fabry-Perot instruments and a new approach for accurate camera co-alignment for image restoration. We document a procedure that forms the basis of current state of the art processing of data from the CRISP imaging spectropolarimeter at the Swedish 1-m Solar Telescope (SST). By collecting, implementing, and testing a suite of computer programs, we have defined a data reduction pipeline for this instrument. This pipeline, CRISPRED, streamlines the process of making science-ready data. It is implemented and operated in IDL, with time-consuming steps delegated to C. CRISPRED will be the basis also for the data pipeline of the forthcoming CHROMIS instrument.

description: Double phosphorylation of protein kinases is a common feature of signalling cascades. This motif may reduce cross-talk between signalling pathways, as the second phosphorylation site allows for proofreading, especially when phosphorylation is distributive rather than processive. Recent studies suggest that phosphorylation can be `pseudo-processive' in the crowded cellular environment, as rebinding after the first phosphorylation is enhanced by slow diffusion. Here, we use a simple model with unsaturated reactants to show that specificity for one substrate over another drops as rebinding increases and pseudo-processive behavior becomes possible. However, this loss of specificity with increased rebinding is typically also observed if two distinct enzyme species are required for phosphorylation, i.e. when the system is necessarily distributive. Thus the loss of specificity is due to an intrinsic reduction in selectivity with increased rebinding, which benefits inefficient reactions, rather than pseudo-processivity itself. We also show that proofreading can remain effective when the intended signalling pathway exhibits high levels of rebinding-induced pseudo-processivity, unlike other proposed advantages of the dual phosphorylation motif.

description: The two elements, yttrium and holmium, form a geochemical twin pair as their cations possess equivalent ratios of charge to radius. However, despite their equal electrostatics, a subtle difference in their fluoride or chloride affinity is known within solutions. In this work, we investigated whether this affinity gap is also present within the solid phase and how it depends on the surface configuration. We modeled adsorptions onto β-YF3 (waimirite) and isostructural β-HoF3 by periodic density functional theory. To draw conclusions on the affinity toward fluoride and chloride vs. water, adsorbates of HF, HCl, or H2O onto any of the four highly abundant surfaces of (010), (100), (011), and (101) were studied. Among others, the conformational landscape was explored by 200 ps of ab initio molecular dynamics. For stoichiometric surfaces of both MF3, we indeed found stronger adsorptions for HF than HCl. All (hkl)⋅H2O showed slightly stronger adsorption energies for HoF3, while for HF and HCl, the metal preferences varied by the surface. While (100) showed the strongest preference for HoF3, (101) preferred YF3 by the same magnitude.

description: We study experimentally the writing of one- and two-dimensional photorefractive lattices, focusing on the often overlooked transient regime. Our measurements agree well with theory, in particular concerning the ratio of the drift to diffusion terms. We then study the transverse dynamics of coherent waves propagating in the lattices, in a few novel and simple configurations. For focused linear waves with broad transverse spectrum, we remark that both the intensity distributions in real space ("discrete diffraction") and Fourier space ("Brillouin zone spectroscopy") reflect the Bragg planes and band structure. For non-linear waves, we observe modulational instability and discrete solitons formation in time domain. We discuss also the non-ideal effects inherent to the photo-induction technique : anisotropy, residual nonlinearity, diffusive term, non-stationarity.

Demographic change and assimilation in the early 21st-century United States

description: Assimilation has not gotten its due in recent decades, overshadowed by discussions about race and racism. Using evidence from the 2000 Census and the 2015 to 2019 American Community Survey, we show, however, that contemporary social change and its implications for a society stratified along ethnoracial lines cannot be understood without taking the assimilation of many Americans with non-White or Hispanic family origins into account. We begin by necessity with a reconsideration of the concept, arguing that assimilation involves the decline in influence of ethnoracial origins on social status and on relationships with others; it does not require the erasure of all markers of those origins. We highlight that demographic dynamics are playing a critical role in promoting assimilation: Ethnoracial shifts across birth cohorts are generating opportunities for minority mobility, and increasing mixing in families is engendering a growing group of young Americans from mixed minority–White family backgrounds. These mixed Americans, we argue, offer the clearest window into assimilation processes, which are not limited to them, however. The empirical evidence presented shows effects on both social status and relations across group boundaries: 1) the top tier of the workforce, the best-paid quartile of occupations, is growing much more ethnoracially diverse over time, and mixed minority–White Americans are important to this diversity because their probabilities of entering this tier are more similar to those of White people than are those of unmixed minorities; and 2) intermarriage remains robust, enhanced by high rates of marriage to White people by mixed minority–White individuals.

description: Nonlinear analyses investigate the dynamics of observed time-ordered data. Such dynamics, for this thesis, are complex systems of sensorimotor variables of movement variability (MV) in the context of human-humanoid interaction. Hence, this dissertation not only explores questions such as what to quantify in MV?, or which nonlinear tools are appropriate to quantify MV?, but also how nonlinear analyses are affected with real-world time series data (e.g. nonstationary, data length limitations, sampling rate changes or noisiness). Particularly, I review nonlinear tools such as methods to determine embedding parameters, Reconstructed State Spaces (RSSs), Recurrence Plots (RPs) and Recurrence Quantification Analyses (RQA). To my knowledge, I can conclude that, no scientific work has been reported regarding nonlinear analyses (e.g. RSSs with UTDE, RPs and RQAs) to quantify movement variability in the context of human-humanoid interaction. Also, we created 3D surfaces of RQA values considering the variation of embedded parameters and recurrence thresholds to show that 3D surfaces of RQA ENTR might be a better approach to provide understanding on the dynamics of different characteristic of real-world time series data. I can foresee many areas of applications where humanoids robots can be pre-programmed with nonlinear analyses algorithms to evaluate the improvement of movement performances, to quantify and provide feedback of skill learning or to quantify movement adaptations and pathologies.

A spectral/hp element DNS study of flow past low-pressure turbine cascades and the effects of inflow conditions
Creators: name: Cassinelli, Andrea
Publisher: name: Imperial College London
Year: 2020

description: The combined rapid progress of hardware capability and the development of cutting-edge numerical methods have recently provided an opportunity for Computational Fluid Dynamics to be inserted in the design loop, with the role of a virtual wind tunnel. This thesis tackles the development of a validated incompressible Direct Numerical Simulation capability to model complex configurations of interest for the turbomachinery Industry, adopting for the first time the spectral/hp element methods implemented in the Nektar++ software framework. First, an extensive analysis of the numerical convergence properties is carried out on an open geometry with clean inflow boundary conditions, to establish a set of best practices and relate accuracy and computational cost. Subsequently, the effect of stochastic and deterministic unsteadiness is analysed in detail, with particular focus on various methodologies to provide physical disturbances, their computational cost and accuracy with respect to reference experimental data. The findings are extended to a range of Reynolds numbers representative of realistic operating conditions, with focus on traditional performance indicators but also unsteady statistics to provide rich insight into the suction surface transition mechanism, which plays a crucial role in the generation of profile losses. As a result, a detailed characterisation of the flow physics is provided in a range of inflow conditions and Reynolds numbers. Excellent agreement with high fidelity experimental data is achieved especially at moderate and high Reynolds numbers, supporting the use of these methodologies in Industry as a preliminary standalone investigation tool.
Short-ranged interaction effects on $Z_2$ topological phase transitions: The perturbative mean-field method

description: Time-reversal symmetric topological insulator is a novel state of matter that a bulk-insulating state carries dissipationless spin transport along the surfaces, embedded by the $Z_2$ topological invariant. In the noninteracting limit, this exotic state has been intensively studied and explored with realistic systems, such as HgTe/(Hg,Cd)Te quantum wells. Yet an interacting topological insulator is still an elusive subject, and most related analyses rely on the mean-field approximation and numerical simulations. Among the approaches, the mean-field approximation fails to predict the topological phase transition, in particular at intermediate interaction strength without spontaneously breaking symmetry. In this review, we develop an analytical approach based on a combined perturbative and self-consistent mean-field treatment of interactions that is capable of capturing topological phase transitions beyond either method when used independently. As an illustration of the method, we study the effects of short-ranged interactions on the $Z_2$ topological insulator phase, also known as the quantum spin Hall phase, in three generalized versions of the Kane-Mele model at half-filling on the honeycomb lattice. The results are in excellent agreement with quantum Monte Carlo calculations on the same model, and cannot be reproduced by either a perturbative treatment or a self-consistent mean-field treatment of the interactions. Our analytical approach helps to clarify how the symmetries of the one-body terms of the Hamiltonian determine whether interactions tend to stabilize or destabilize a topological phase. Moreover, our method should be applicable to a wide class of models where topological transitions due to interactions are in principle possible, but are not correctly predicted by either perturbative or self-consistent treatments.

title: Herrscherideologie und Herrschaftsrepräsentation in den kirchenslawischen und lateinischen Königsurkunden des mittelalterlichen Bosniens
Creators: name: Treber, Mario
Year: 2021

description: In dieser Forschungsarbeit sollen ausgewählte Auszüge aus den (kirchen)slawischen und lateinischen Formularen der Königsurkunden des mittelalterlichen Bosniens im Hinblick auf Herrscherideologie und Herrschaftsrepräsentation ausgewertet und analysiert werden. Da sich der Verfasser dieser Arbeit auf die in der bereits genannten Quellenedition dargestellten Urkunden beziehen wird, wird dabei die Untersuchung der Urkundentexte im Vordergrund stehen, da er nur auf die Photographien derselben zurückgreifen kann. Dies bedeutet, dass vorwiegend die inneren Merkmale der Urkunden analysiert werden sollen. Weil aus der Zeit des mittelalterlichen Bosniens keine klassisch narrativen, demnach historiographischen Quellen überliefert sind, soll sich diese Arbeit den ideengeschichtlich relevanten Elementen der Königsurkunden widmen, wobei diese insbesondere in Bezug auf Herrscheridee und Herrschaftsrepräsentation befragt werden sollen, nicht jedoch um ein bloßes Daten- und Faktengerüst der mittelalterlichen bosnischen Geschichte zu rekonstruieren. Dabei soll der Analyse der Intitulationes und Arengen in den Urkundenformularen besondere Aufmerksamkeit zuteil werden. Das heuristische Interesse dieser Arbeit liegt vorrangig darin, zu untersuchen, inwiefern sich Herrscheridee und Herrschaftsrepräsentation der bosnischen Könige anhand ideengeschichtlich bedeutsamer Elemente in den kirchenslawischen und lateinischen Urkunden manifestieren. Es wird zu untersuchen sein, ob und inwieweit sich die Repräsentation von Herrschaft und die Artikulation ideologischer Versatzstücke in den (kirchen)slawischen und lateinischen Urkunden nachweisen lässt und inwiefern sich die Ausgestaltung der Intitulationes und Arengen in den genannten Kanzleisprachen voneinander unterscheidet. Dabei wird mitunter auch zu fragen sein, woher die bosnischen „Königskanzleien“ und ihre Schreiber ihr Wissen darüber bezogen, wie die Ausgestaltung der Königsurkunden zu erfolgen hatte. Bezogen sie sich dabei etwa auf bestimmte Traditionen (Byzanz, Serbien, Ungarn-Kroatien, Venedig etc.)?
Structural and functional analysis of DDR1 autoinhibition
Creators: name: Sammon, Douglas James
Publisher: name: Imperial College London
Year: 2020

description: Discoidin domain receptor 1 (DDR1) is a collagen activated receptor tyrosine kinase (RTK) which controls cellular proliferation and migration. DDR1 plays important roles in organogenesis and wound healing. Furthermore, aberrant DDR1 signalling is implicated in the progression and poor prognosis of several diseases, including organ fibroses and cancers. DDR1 is therefore an attractive target for pharmacological intervention. However, unlike in many other RTKs, the regulatory mechanisms underpinning DDR1 signalling are poorly understood. This project investigated the regulatory function of the long intracellular juxtamembrane (JM) region of DDR1. The kinase proximal JM segment, termed JM4, is shown to be an important regulator of DDR1 kinase activity. A 2.58 Å resolution crystal structure revealed that the JM4 segment forms a hairpin which enters the kinase active site and reinforces activation loop autoinhibition. Enzymological analysis of purified DDR1 constructs demonstrated that this autoinhibition is relieved in an ordered process which begins with the rapid, in cis, phosphorylation of the JM4 segment (Tyr569 and Tyr586), followed by slow, in trans, phosphorylation of the activation loop (Tyr796). Both successive phosphorylation events are shown to have drastic activating effects on the kinase catalytic rate. Analysis of cell expressed DDR1 also revealed that JM4 Tyr mutation (DDR1-Y569F/Y586F) abolishes collagen induced receptor activation. A secondary positive role for the JM4 region in DDR1 activation is also identified through cell-based analysis. This role could be the recruitment of Src, a non-receptor tyrosine kinase, which is shown to be an activator of DDR1, but not DDR1-Y569F/Y586F, signalling. The identification of the DDR1 JM4 region as a regulator of receptor signalling provides an interesting avenue for the development of DDR1-specific kinase inhibitors.

description: The Fe(1+x)Sb compound has been synthesized close to stoichiometry with x = 0.023(8). The compound was investigated by 57Fe Mössbauer spectroscopy in the temperature range 4.2 - 300 K. The antiferromagnetic ordering temperature was found as 232 K i.e. much higher than for the less stoichiometric material. Regular iron was found to occupy two different positions in proportion 2:1. They differ by the electric quadrupole coupling constants and both of them exhibit extremely anisotropic electric field gradient tensor (EFG) with the asymmetry parameter equal one. The negative component of both EFGs is aligned with the c-axis of the hexagonal unit cell, while the positive component is aligned with the <120> direction. Hence, a model describing deviation from the NiAs P63/mmc symmetry group within Fe-planes has been proposed. Spectra in the magnetically ordered state could be explained by introduction of the incommensurate spin spirals propagating through the iron atoms in the direction of the c-axis with a complex pattern of the hyperfine magnetic fields distributed within a-b plane. Hyperfine magnetic field pattern of spirals due to major regular iron is smoothed by the spin polarized itinerant electrons, while the minor regular iron exhibits hyperfine field pattern characteristic of the highly covalent bonds to the adjacent antimony atoms. The excess interstitial iron orders magnetically at the same temperature as the regular iron, and magnetic moments of these atoms are likely to form two-dimensional spin glass with moments lying in the a-b plane. The upturn of the hyperfine field for minor regular iron and interstitial iron is observed below 80 K. Magneto-elastic effects are smaller than for FeAs, however the recoilless fraction increases significantly upon transition to the magnetically ordered state.
The role of the ion channel TRPV4 in the Late Asthmatic Response
Creators: name: Flajolet, Pauline Léa Marie
Publisher: name: Imperial College London

description: In some patients, asthma is thought to be an atopic disease whereby exposure to allergens provokes symptoms. In fact, allergen inhalation can lead to a prolonged episode of airway narrowing named the late asthmatic response (LAR). Although it is a relevant clinical endpoint, the mechanisms driving it remain unclear. Evidence suggests that nerves could be involved, with allergen challenge resulting in the activation of airway sensory nerves within the vagus nerve and a subsequent reflex bronchospasm. This thesis investigated if the TRPV4 ion channel, a known activator of sensory nerves, could be a driver of the LAR. The ability of TRPV4 to stimulate airway sensory nerves was studied in Brown Norway rats. A TRPV4 agonist depolarised rat vagal nerves and this was inhibited by TRPV4 and P2X3-P2X2/3 antagonists, suggesting that TRPV4 signalling induces the release of ATP which stimulates P2X3-P2X2/3 receptors on the neurons. Therefore, further studies interrogated whether this TRPV4-P2X3 nerve axis could be driving the LAR. Accordingly, both TRPV4 and P2X3-P2X2/3 antagonists inhibited the LAR induced by ovalbumin (OVA) in Brown Norway rats, suggesting a role for the TRPV4-P2X3 axis in experimental LAR. Seeing these results, the mechanism leading to TRPV4 activation was investigated. PAR2 receptors, which are activated by proteases released upon allergen challenge, were considered as promising TRPV4 activators. Indeed, a PAR2 agonist depolarised rat vagal nerves and this was blocked by PAR2, TRPV4 and P2X3-P2X2/3 antagonists. However, two PAR2 antagonists did not reduce the LAR in the rat OVA model, suggesting that PAR2 receptors may not be involved in this model. Overall, these data suggest that the TRPV4-P2X3 axis could play a role in the LAR by activating airway sensory nerves. This thesis highlights that investigating receptors on airway sensory nerves could help to develop asthma therapies targeting alternative mechanisms than immune pathways.

description: The interaction of an $E/A$=57.6-MeV $^{17}$Ne beam with a Be target was used to populate levels in $^{16}$Ne following neutron knockout reactions. The decay of $^{16}$Ne states into the three-body $^{14}$O+$p$+$p$ continuum was observed in the High Resolution Array (HiRA). For the first time for a 2p emitter, correlations between the momenta of the three decay products were measured with sufficient resolution and statistics to allow for an unambiguous demonstration of their dependence on the long-range nature of the Coulomb interaction. Contrary to previous experiments, the intrinsic decay width of the $^{16}$Ne ground state was found to be narrow ($Γ<60$~keV), consistent with theoretical estimates.

However, current systems face challenges with the separation of state modulation and acquisition, leading to undesired time delays that impact real-time performance. To overcome this issue, we introduce a dual-function circuit that concurrently modulates and acquires memristor state information. This is achieved through two key features: 1) a feedback operational amplifier (op-amp) based circuit that ensures precise voltage application on the memristor while converting the passing current into a voltage signal; 2) a division calculation circuit that acquires state information from the modulation voltage and the converted voltage, improving stability by leveraging the intrinsic threshold characteristics of memristors. This circuit has been evaluated in a memristor-based nociceptor and a memristor crossbar, demonstrating exceptional performance. For instance, it achieves mean absolute acquisition errors below 1 Ω during the modulation process in the nociceptor application. These results demonstrate that the proposed circuit can operate at different scales, holding the potential to enhance a wide range of neuromorphic applications.

description: Understanding crystal characteristics down to the atomistic level increasingly emerges as a crucial insight for creating solid state platforms for qubits with reproducible and homogeneous properties. Here, isotope composition depth profiles in a SiGe/$^{28}$Si/SiGe heterostructure are analyzed with atom probe tomography (APT) and time-of-flight secondary-ion mass spectrometry. Spin-echo dephasing times $T_2^{echo}=128 μs$ and valley energy splittings around $200 μeV$ have been observed for single spin qubits in this quantum well (QW) heterostructure, pointing towards the suppression of qubit decoherence through hyperfine interaction or via scattering between valley states. The concentration of nuclear spin-carrying $^{29}$Si is 50 ppm in the $^{28}$Si QW. APT allows to uncover that both the top SiGe/$^{28}$Si and the bottom $^{28}$Si/SiGe interfaces of the QW are shaped by epitaxial growth front segregation signatures on a few monolayer scale. A subsequent thermal treatment broadens the top interface by about two monolayers, while the width of the bottom interface remains unchanged. Using a tight-binding model including SiGe alloy disorder, these experimental results suggest that the combination of the slightly thermally broadened top interface and of a minimal Ge concentration of $0.3 \%$ in the QW, resulting from segregation, is instrumental for the observed large valley splitting. Minimal Ge additions $< 1 \%$, which get more likely in thin QWs, will hence support high valley splitting without compromising coherence times. At the same time, taking thermal treatments during device processing as well as the occurrence of crystal growth characteristics into account seems important for the design of reproducible qubit properties.

description: The modelling of symmetric rigid dumbbell particles suspended in a Newtonian fluid, as a model of a rigid-rod polymeric solution, has been accomplished exclusively through the diffusion equation, which has been detailed elegantly by Bird et al. [Chapter 14 of $Dynamics \ of \ Polymeric \ Liquids$, Vol 2, Ed 2, (1987)]. In this tutorial, a straightforward approach for modelling a lopsided rigid dumbbell particle is presented by the Langevin analysis. The connector force between the dumbbell beads is obtained through the rigidity constraint of the center-to-center vector of the dumbbell using its Langevin equation. By directly averaging via the Langevin equation, the evolution of the center-to-center vector, and the configuration tensor are derived. The stress expressions for the dumbbell from the Langevin equation, and the diffusion equation for the orientation distribution function of the center-to-center vector of the dumbbell are also derived, and the final expressions agree with established results from other methods.

description: Euphonic conjunctions (sandhis) form a very important aspect of Sanskrit morphology and phonology. The traditional and modern methods of studying about euphonic conjunctions in Sanskrit follow different methodologies. The former involves a rigorous study of the Paninian system embodied in Panini's Ashtadhyayi, while the latter usually involves the study of a few important sandhi rules with the use of examples. The former is not suitable for beginners, and the latter, not sufficient to gain a comprehensive understanding of the operation of sandhi rules. This is so since there are not only numerous sandhi rules and exceptions, but also complex precedence rules involved. The need for a new ontology for sandhi-tutoring was hence felt. This work presents a comprehensive ontology designed to enable a student-user to learn in stages all about euphonic conjunctions and the relevant aphorisms of Sanskrit grammar and to test and evaluate the progress of the student-user. The ontology forms the basis of a multimedia sandhi tutor that was given to different categories of users including Sanskrit scholars for extensive and rigorous testing.

description: We study novel type of contributions to the partition function of the Maxwell system defined on a small compact manifold such as torus. These new terms can not be described in terms of the physical propagating photons with two transverse polarizations. Rather, these novel contributions emerge as a result of tunnelling events when transitions occur between topologically different but physically identical vacuum winding states. These new terms give an extra contribution to the Casimir pressure. The infrared physics in the system can be described in terms of the topological auxiliary non-propagating fields $a_i(\mathbf{k})$ governed by Chern-Simons -like action. The system can be studied in terms of these auxiliary fields precisely in the same way as a topological insulator can be analyzed in terms of Berry's connection ${\cal{A}}_i(\mathbf{k})$. We also argue that the Maxwell vacuum defined on a small 4-torus behaves very much in the same way as a topological insulator with $θ\neq 0$.

description: While diffusion models have significantly advanced the quality of image generation their capability to accurately and coherently render text within these images remains a substantial challenge. Conventional diffusion-based methods for scene text generation are typically limited by their reliance on an intermediate layout output. This dependency often results in a constrained diversity of text styles and fonts an inherent limitation stemming from the deterministic nature of the layout generation phase. To address these challenges this paper introduces SceneTextGen a novel diffusion-based model specifically designed to circumvent the need for a predefined layout stage. By doing so SceneTextGen facilitates a more natural and varied representation of text. The novelty of SceneTextGen lies in its integration of three key components: a character-level encoder for capturing detailed typographic properties coupled with a character-level instance segmentation model and a word-level spotting model to address the issues of unwanted text generation and minor character inaccuracies. We validate the performance of our method by demonstrating improved character recognition rates on generated images across different public visual text datasets in comparison to both standard diffusion based methods and text specific methods.

Unconditionally secure commitment in position-based quantum cryptography

description: A new commitment scheme based on position-verification and non-local quantum correlations is presented here for the first time in literature. The only credential for unconditional security is the position of committer and non-local correlations generated; neither receiver has any pre-shared data with the committer nor does receiver require trusted and authenticated quantum/classical channels between him and the committer. In the proposed scheme, receiver trusts the commitment only if the scheme itself verifies position of the committer and validates her commitment through non-local quantum correlations in a single round. The position-based commitment scheme bounds committer to reveal valid commitment within allocated time and guarantees that the receiver will not be able to get information about commitment unless committer reveals. The scheme works for the commitment of both bits and qubits and is equally secure against committer/receiver as well as against any third party who may have interests in destroying the commitment. Our proposed scheme is unconditionally secure in general and evades Mayers and Lo-Chau attacks in particular.

description: We analyze the projected sensitivity of a laboratory-scale ytterbium atom interferometer to scalar, vector, and axion dark matter signals. A frequency ratio measurement between two transitions in $^{171}$Yb enables a search for variations of the fine-structure constant that could surpass existing limits by a factor of 100 in the mass range $10^{-22}$ eV to $10^{-16}$ eV. Differential accelerometry between Yb isotopes yields projected sensitivities to scalar and vector dark matter couplings that are stronger than the limits set by the MICROSCOPE equivalence principle test, and an analogous measurement in the MAGIS-100 long-baseline interferometer would be more sensitive than previous bounds by factors of 10 or more. A search for anomalous spin torque in MAGIS-100 is projected to reach similar sensitivity to atomic magnetometry experiments. We discuss strategies for mitigating the main systematic effects in each measurement. These results indicate that improved dark matter searches with Yb atom interferometry are technically feasible.
