description: We studied the upper bounds of the holographic entanglement entropy growth rate for thermofield double (TFD) states. By comparing the cases of vacuum AdS and charged AdS black holes, we conjecture: for all static planar or spherically symmetric asymptotically Schwarzschild-AdS black holes of same mass density or entropy density, the vacuum AdS black hole gives the maximum entanglement entropy growth rate. We gave proofs by assuming dominant energy condition. We also considered the AdS black hole spacetime with real scalar fields case, where the scalar fields violate the dominant energy condition and the bulk geometry is not asymptotically Schwarzschild-AdS. Numerical results show that this case vacuum black hole still has maximal growth rate if we fixed entropy. However, in the case of fixed energy, vacuum case has maximal growth rate of entanglement entropy only under standard quantization scheme.

description: We point out the possibility of occurring instabilities in Laughlin liquids of rotating dipolar fermions with zero thickness. Previously such a system was predicted to be the Laughlin liquid for filling factors being greater and equal to 1/7. However, from intra-Landau-level excitations of the liquid in the single-mode approximation, the roton minima become negative and Laughlin liquids are unstable for filling factors being less and equal to 1/7. We then conclude that there are correlated Wigner crystals for filling factors being less and equal to 1/7.

description: We study the properties of the Lindbladian quantum mechanical evolution of quarkonia with non-Abelian charges (color-singlet and octet) in the quark-gluon plasma. We confirm that heavy quark recoils in the Lindblad equation correctly thermalize quarkonium colorful states within statistical errors from the simulation method. We also demonstrate that the Lindblad equation in the dipole limit can provide an efficient alternative method, which is applicable to a finite time evolution before thermalization and dramatically reduces the numerical cost. Our findings will serve as a foundation for large-scale simulation of quarkonium dynamics in the relativistic heavy-ion collisions.

description: Managerial support in professional nursing practice is crucial in establishing
 and maintaining a healthy practice environment. It is believed that these variables play
 an important role in staff retention, job satisfaction, and turnover rates. This academic
 work determined the perceived managerial support, practice environment and its
 rela􀁗ion 􀁗o 􀁖􀁗aff n􀁘r􀁖e􀂶􀁖 demographic profile emplo􀁜ed in a 􀁖elec􀁗ed le􀁙el 4
 government-owned and controlled corporate tertiary healthcare facility located in
 Metro Manila, Philippines.
 The study used a descriptive correlational design and facilitated two
 international validated research instruments, namely Supervisory support scale (SSS)
 tool, and American Association of Critical-care Nursing Healthy Work Environment
 Assessment Tool (AACN-HWEAT). Pearson correlation coefficient was used to
 identify the relationship of perceived level managerial support and nurse-re􀁖ponden􀁗􀁖􀂶
 practice environment. The Chi-square test of independence was facilitated to identify
 the difference between practice environment and demographic profile of nurserespondents.
 Data gathered from nurse-respondents (N=519) showed a high level of
 perceived managerial support and positive practice environments. However, results
 highlighted that only one of the six healthy work environment essential standards,
 namely the true collaboration, scored the lowest mean value, (M=1.92; SD=0.32)
 depicting a negative practice environment. While the SSS domains mostly show
 significant correlations on HWE essential standards, the effective decision-making
 essential standard found no significant correlation with SSS being reliable domain,
 r(517) = .063; p>.152, whereas the authentic leadership essential standard showed
 non-significant relationship with both SSS domains, namely respects uniqueness,r(517) = .005, p> .990; and being reliable, r(517) = -.054, p> .220. Also, study findings
 showed a significant association between practice environment essential standards
 and 􀁖􀁗aff n􀁘r􀁖e􀂶􀁖 demographic profile, p<.0001.
 Nurse practice environment should be a priority for healthcare leaders and
 administrators because it is evidently a critical factor in the provision of quality patient
 care, organizational success, as well as in the improvement of the overall professional
 nursing practice.

description: We study the effect of weak disorder on tunneling conductance of a single-channel quantum ring threaded by magnetic flux. We assume that temperature is higher than the level spacing in the ring and smaller than the Fermi energy. In the absence of disorder, the conductance shows sharp dips (antiresonances) as a function of magnetic flux. We discuss different types of disorder and find that the short-range disorder broadens antiresonances, while the long-range one leads to arising of additional resonant dips. We demonstrate that the resonant dips have essentially non-Lorentzian shape. The results are generalized to account for the spin-orbit interaction which leads to splitting of the disorder-broadened resonant dips, and consequently to coexisting of two types of oscillations (both having the form of sharp dips): Aharonov-Bohm oscillations with magnetic flux and Aharonov-Casher oscillations with the strength of the spin-orbit coupling. We also discuss the effect of the Zeeman coupling.

description: A contemporary feed application usually provides blended results of organic items and sponsored items~(ads) to users. Conventionally, ads are exposed at fixed positions. Such a static exposure strategy is inefficient due to ignoring users' personalized preferences towards ads. To this end, adaptive ad exposure has become an appealing strategy to boost the overall performance of the feed. However, existing approaches to implementing the adaptive ad exposure still suffer from several limitations: 1) they usually fall into sub-optimal solutions because of only focusing on request-level optimization without consideration of the long-term application-level performance and constraints, 2) they neglect the necessity of keeping the game-theoretical properties of ad auctions, which may lead to anarchy in bidding, and 3) they can hardly be deployed in large-scale applications due to high computational complexity. In this paper, we focus on long-term performance optimization under hierarchical constraints in feeds and formulate the adaptive ad exposure as a Dynamic Knapsack Problem. We propose an effective approach: Hierarchically Constrained Adaptive Ad Exposure~(HCA2E). We present that HCA2E possesses desired game-theoretical properties, computational efficiency, and performance robustness. Comprehensive offline and online experiments on a leading e-commerce application demonstrate the significant performance superiority of HCA2E over representative baselines. HCA2E has also been deployed on this application to serve millions of daily users.

Publisher: name: Old Dominion University Libraries

description: The following is comprised of: (1) an analysis of scholarship and contemporary works regarding videogames and museums that demonstrate the theory and method behind this project, (2) research regarding an historic maritime event that will serve as the subject matter for the proposed videogame, and (3) a conclusion that summarizes the game design. The historical research at the heart of this project surrounds the SS Quanza, a steamship that in September of 1940 carried Jewish refugees from Portugal to the US and Mexico only to be faced with the possibility of a return trip to Nazi Europe. Elevating the voices of the Quanza’s refugees and their advocates exposes a lack of a maritime perspective in Holocaust studies broadly, as well as, demonstrates a popular and empathetic regard for those fleeing Nazi Europe. Comparing videogames and museum exhibitions provides invaluable insights that are new to both game studies and museum studies. This endeavor suggests that game space and exhibit space have many similarities and that museum visitors and gamers are not dissimilar. We can consider videogames to be cultural and social artifacts in the likeness of museum collections. Gamers and museum visitors are likely to be the same audience, hence the efforts of the museum world to incorporate new technologies and game-based programming. But what if videogames can offer meaningful experiences for the gamer-visitor audience outside of the museum? Ultimately this project incorporates academic research into meaningful videogame design and considers the social epistemological dimensions of videogames.

description: Paraná Ra'anga (the image of Paraná, in Guaraní) is the name of a cultural and scientific expedition that traveled the rivers: Río de la Plata, Paraná and Paraguay, from Buenos Aires to Asunción, during March 2010. The project brought together some forty scientists and artists from three countries in a slow and enriching cruise, putting in active contact actors from different backgrounds and disciplines -which usually run separately- in the framework of an unusual space-time experience. The project recovers the historical tradition of the trip as an instrument of knowledge and collaboration between the arts and sciences, necessary to build new ways of seeing and understanding the river and its banks. This article reports on the motivations of this project and its projection.

title: Teacher and Child Interaction: The Effects of Familial Distress, Child Behavior, and Teacher Perceptions
Creators: name: Ennis, Jessekah R.
Publisher: name: Old Dominion University Libraries
Year: 2019

description: There has been a significant amount of research that has studied the ecological conditions that create behavioral problems for children from families that are female headed, in poverty, and live in areas where there is violent crime. There has also been evidence that revealed statistically significant associations between the way teachers perceive students from low socioeconomic backgrounds and their beliefs of the capacity of the children to learn. Studies have also examined how teachers interact with children that are exhibiting behavioral problems that are from low socio-economic status. However, to date there has been no study that has combined these ecological conditions of female headed households, poverty, exposure to violent crime, behavioral problems, and teacher perceptions effects on the way teachers interact with them through reading instructional activities. This thesis uses a three-model analysis that examines this relationship as well as relevant control variables that have been found to be significantly associated with teacher interactions and instructional time. The results indicated that the greater the perception of violent crime the greater amount of time children spend in teacher directed individual reading activities. Also, the results indicated that teachers who responded neutrally to perceived problem behaviors affecting instruction were more likely to spend a greater amount of time with students in teacher directed individual reading activities whose families are female headed, living in poverty, and from communities where violent crime is a big problem. These results indicate that while controlling for relevant control variables violent crime and perception of behavior have a significant effect on the amount of time teachers spend in teacher directed individual reading activities. The findings of violent crime and neutrality concerning problem behavior effects on the amount of time spent in teacher directed individual reading activities are of particular interest for future research.
Origin of the Q^2-dependence of the DIS structure functions

description: We consider in detail the Q^2 -dependence of the DIS structure functions, with Q being the virtual photon momentum. Quite often this dependence is claimed to be originated by the Q^2-dependence of the QCD coupling. This leads to the small-x asymptotics of the structure functions with Q^2 -dependent intercepts. We demonstrate that the DGLAP parametrization alpha_s = alpha_s (Q^2) is an approximation valid in the region of large x (where 2pq can be approximated by Q^2) only, providing the factorization scale is also large. Outside this region, the DGLAP parametrization fails, so alpha_s should be replaced by an effective coupling which is independent of Q^2 at small x. As a consequence, intercepts of the structure functions are independent of Q^2. Nevertheless, the small-x asymptotics of the structure functions explicitly depend on Q^2, even when the coupling does not depend on it. We also consider the structure functions at small Q^2 and give a comment on power-Q^2 corrections to the structure functions at large and small Q^2

description: For conventional imaging, the imaging resolution limit is given by the Rayleigh criterion. Exploiting the prior knowledge of imaging object's sparsity and fixed optical system, imaging beyond the conventional Rayleigh limit, which is backed up by numerical simulation and experiments, is achieved by illuminating the object with single-shot thermal light and detecting the object's information at the imaging plane with some sparse-array single-pixel detectors. The quality of sub-Rayleigh imaging with sparse detection is also shown to be related to the effective number of single-pixel detectors and the detection signal-to-noise ratio at the imaging plane.

description: This chapter is a tutorial on techniques and results in free convex algebraic geometry and free real algebraic geometry (RAG). The term free refers to the central role played by algebras of noncommutative polynomials R in free (freely noncommuting) variables x=(x_1,...,x_g). The subject pertains to problems where the unknowns are matrices or Hilbert space operators as arise in linear systems engineering and quantum information theory. The subject of free RAG flows in two branches. One, free positivity and inequalities is an analog of classical real algebraic geometry, a theory of polynomial inequalities embodied in algebraic formulas called Positivstellensätze; often free Positivstellensätze have cleaner statements than their commutative counterparts. Free convexity, the second branch of free RAG, arose in an effort to unify a torrent of ad hoc optimization techniques which came on the linear systems engineering scene in the mid 1990's. Mathematically, much as in the commutative case, free convexity is connected with free positivity through the second derivative: A free polynomial is convex if and only if its Hessian is positive. However, free convexity is a very restrictive condition, for example, free convex polynomials have degree 2 or less. This article describes for a beginner techniques involving free convexity. As such it also serves as a point of entry into the larger field of free real algebraic geometry.

Simple curve singularities

Subjects: subject: Algebraic Geometry (math.AG)

description: We classify simple parametrisations of complex curve singularities. Simple means that all neighbouring singularities fall in finitely many equivalence classes. We take the neighbouring singularities to be the ones occurring in the versal deformation of the parametrisation. This leads to a smaller list than that obtained by looking at the neighbours in a fixed space of multi-germs. Our simple parametrisations are the same as the fully simple singularities of Zhitomirskii, who classified real plane and space curve singularities. The list of simple parametrisations of plane curves is the A-D-E list. Also for space curves the list coincides with the lists of simple curves of Giusti and Frühbis-Krüger, in the sense of deformations of the curve. For higher embedding dimension no classification of simple curves is available, but we conjecture that even there the list is exactly that of curves with simple parametrisations.

description: Mixing effects on the mass spectrum of light neutral pseudoscalar and vector mesons in the presence of an external uniform magnetic field $\vec B$ are studied in the framework of a two-flavor NJL-like model. The model includes isoscalar and isovector couplings both in the scalar-pseudoscalar and vector sectors, and also incorporates flavor mixing through a 't Hooft-like term. Numerical results for the $B$ dependence of meson masses are compared with present lattice QCD results. In particular, it is shown that the mixing between pseudoscalar and vector meson states leads to a significant reduction of the mass of the lightest state. The role of chiral symmetry and the effect of the alignment of quark magnetic moments in the presence of the magnetic field are discussed.

Under-approximating Cut Sets for Reachability in Large Scale Automata Networks

description: In the scope of discrete finite-state models of interacting components, we present a novel algorithm for identifying sets of local states of components whose activity is necessary for the reachability of a given local state. If all the local states from such a set are disabled in the model, the concerned reachability is impossible. Those sets are referred to as cut sets and are computed from a particular abstract causality structure, so-called Graph of Local Causality, inspired from previous work and generalised here to finite automata networks. The extracted sets of local states form an under-approximation of the complete minimal cut sets of the dynamics: there may exist smaller or additional cut sets for the given reachability. Applied to qualitative models of biological systems, such cut sets provide potential therapeutic targets that are proven to prevent molecules of interest to become active, up to the correctness of the model. Our new method makes tractable the formal analysis of very large scale networks, as illustrated by the computation of cut sets within a Boolean model of biological pathways interactions gathering more than 9000 components.

description: László Fejes Tóth and Aladár Heppes proposed the following generalization of the kissing number problem. Given a ball in $\mathbb{R}^d$, consider a family of balls touching it, and another family of balls touching the first family. Find the maximal possible number of balls in this arrangement, provided that no two balls intersect by interiors, and all balls are congruent. They showed that the answer for disks on the plane is $19$. They also conjectured that if there are three families of disks instead of two, the answer is $37$. In this paper we confirm this conjecture.

description: Recent terahertz conductivity measurements observed low-power-law frequency dependence of optical conduction within the Mott gap of the Kagome lattice spin-liquid candidate Herbertsmithite. We investigate mechanisms for this observed sub-gap conductivity for two possible scenarios in which the ground-state is described by: 1) a U(1) Dirac spin-liquid with emergent fermionic spinons or 2) a nearly critical Z2 spin-liquid in the vicinity of a continuous quantum phase transition to magnetic order. We identify new mechanisms for optical-absorption via magneto-elastic effects and spin- orbit coupling. In addition, for the Dirac spin-liquid scenario, we establish an explicit microscopic origin for previously proposed absorption mechanisms based on slave-particle effective field theory descriptions.

description: From a prevention standpoint, it is crucial to investigate which segment of the population develops problematic outcomes in different life domains in adulthood as these persons are the ones in need of societal resources. Moreover, to prevent the need for extensive societal resources, we need to examine predictors originating early in life. This knowledge can inform prevention approaches. A previous study in New Zealand by Caspi and colleagues (2016) found that a segment of 20% of their study population predicted a disproportionate high amount of negative economic and physical health outcomes. Up to date, studies in Netherlands have not yet examined specific population segments which could be targeted for prevention and early intervention approaches as well as which aspects would need to be targeted by prevention strategies. Besides, even in the New Zealand study, mental health was not studied as a negative economic outcome. The current study has two main goals: First, we will replicate the New Zealand study in a larger, well-powered Dutch population-cohort study. Second, we will expand the investigation by focusing on two outcome domains: 1) work & finances, and 2) mental health.

description: The Coast Survey Development Laboratory (CSDL) of the National Ocean Service (NOS) previously developed an Extratropical Surge and Tide Operational Forecast System (ESTOFS) for the US coastal waters (Funakoshi et al. 2013). Now, to extend the capability of ESTOFS to include tropical storm event simulation and ensemble prediction, CSDL is preparing a prototype Hurricane Storm Surge Operational Forecast System (HSSOFS). Under direction from CSDL, a technical team led by Riverside Technology, inc. has developed a hydrodynamic model of the US East Coast and Gulf of Mexico and has validated the model for 10 major tropical and extratropical events. Eventually, this model will form the basis for an operational system on National Centers for Environmental Prediction (NCEP) computers. The prototype model described in this document is called NOMAD: NOAA Operational Model with ADCIRC.

description: Telescope pupil fragmentation from spiders generates specific aberrations observed at various telescopes and expected on the large telescopes under construction. This so-called island effect induces differential pistons, tips and tilts on the pupil petals, deforming the instrumental PSF, and is one of the main limitations to the detection of exoplanets with high-contrast imaging. These aberrations have different origins such as the low-wind effect or petaling errors in the adaptive-optics reconstruction. In this paper, we propose to alleviate the impact of the aberrations induced by island effects on high-contrast imaging by adapting the coronagraph design in order to increase its robustness to petal-level aberrations. Following a method first developed for errors due to primary mirror segmentation (segment phasing errors, missing segments...), we develop and test Redundant Apodized Pupils (RAP), i.e. apodizers designed at the petal-scale, then duplicated and rotated to mimic the pupil petal geometry. We apply this concept to the ELT architecture, made of six identical petals, to yield a 10^-6 contrast in a dark region from 8 to 40lambda/D. Both amplitude and phase apodizers proposed in this paper are robust to differential pistons between petals, with minimal degradation to their coronagraphic PSFs and contrast levels. In addition, they are also more robust to petal-level tip-tilt errors than apodizers designed for the whole pupil, with which the limit of contrast of 10^-6 in the coronagraph dark zone is achieved for constraints up to 2 rad RMS of these petal-level modes. The RAP concept proves its robustness to island effects (low-wind effect and post-adaptive optics petaling), with an application to the ELT architecture. It can also be considered for other 8- to 30-meter class ground-based units such as VLT/SPHERE, Subaru/SCExAO, GMT/GMagAO-X, or TMT/PSI.

description: Effects of local availability of mathematics (LAM) and space time dependent number scaling on physics and, especially, geometry are described. LAM assumes separate mathematical systems as structures at each space time point. Extension of gauge theories to include freedom of choice of scaling for number structures, and other structures based on numbers, results in a space time dependent scaling factor based on a scalar boson field. Scaling has no effect on comparison of experimental results with one another or with theory computations. With LAM all theory expressions are elements of mathematics at some reference point. Changing the reference point introduces (external) scaling. Theory expressions with integrals or derivatives over space or time include scaling factors (internal scaling) that cannot be removed by reference point change. Line elements and path lengths, as integrals over space and/or time, show the effect of scaling on geometry. In one example, the scaling factor goes to 0 as the time goes to 0, the big bang time. All path lengths, and values of physical quantities, are crushed to 0 as $t$ goes to 0. Other examples have spherically symmetric scaling factors about some point, $x.$ In one type, a black scaling hole, the scaling factor goes to infinity as the distance, $d$, between any point $y$ and $x$ goes to 0. For scaling white holes, the scaling factor goes to 0 as $d$ goes to 0. For black scaling holes, path lengths from a reference point, $z$, to $y$ become infinite as $y$ approaches $x.$ For white holes, path lengths approach a value much less than the unscaled distance from $z$ to $x.$

description: The Distance Conjecture states that an infinite tower of modes becomes exponentially light when approaching an infinite distance point in field space. We argue that the inherent path-dependence of this statement can be addressed when combining the Distance Conjecture with the recent Tameness Conjecture. The latter asserts that effective theories are described by tame geometry and implements strong finiteness constraints on coupling functions and field spaces. By exploiting these tameness constraints we argue that the region near the infinite distance point admits a decomposition into finitely many sectors in which path-independent statements for the associated towers of states can be established. We then introduce a more constrained class of tame functions with at most polynomial asymptotic growth and argue that they suffice to describe the known string theory effective actions. Remarkably, the multi-field dependence of such functions can be reconstructed by one-dimensional linear test paths in each sector near the boundary. In four-dimensional effective theories, these test paths are traced out as a discrete set of cosmic string solutions. This indicates that such cosmic string solutions can serve as powerful tool to study the near-boundary field space region of any four-dimensional effective field theory. To illustrate these general observations we discuss the central role of tameness and cosmic string solutions in Calabi-Yau compactifications of Type IIB string theory.

Constraints on dark energy from the Lyα forest baryon acoustic oscillations measurement of the redshift 2.3 Hubble parameter

description: We use the Busca et al. (2012) measurement of the Hubble parameter at redshift z = 2.3 in conjunction with 21 lower z measurements, from Simon et al. (2005), Gaztanaga et al. (2009), Stern et al. (2010), and Moresco et al. (2012), to place constraints on model parameters of constant and time-evolving dark energy cosmological models. The inclusion of the new Busca et al. (2012) measurement results in H(z) constraints significantly more restrictive than those derived by Farooq et al. (2012). These H(z) constraints are now more restrictive than those that follow from current Type Ia supernova (SNIa) apparent magnitude measurements (Suzuki et al. 2012). The H(z) constraints by themselves require an accelerating cosmological expansion at about 2-sigma confidence level, depending on cosmological model and Hubble constant prior used in the analysis. A joint analysis of H(z), baryon acoustic oscillation peak length scale, and SNIa data favors a spatially-flat cosmological model currently dominated by a time-independent cosmological constant but does not exclude slowly-evolving dark energy density.

description: The Carolina Digital Repository (CDR) at UNC-Chapel Hill will migrate from custom Fedora to Samvera Hyrax. As part of the content remediation process and preparation for storage and display in the new system, we need to migrate our MODS metadata to RDF. In this presentation, we will explain our repository and metadata use cases, describe the Metadata Application Profile creation process and offer advice and best practices for attendees who are contemplating their own Fedora to Hyrax content migration. We will discuss how legacy content, desired features, and system limitations each informed our decision making.

description: We review the effects of macromolecular crowding on the folding of RNA by considering the simplest scenario when excluded volume interactions between crowding particles and RNA dominate. Using human telomerase enzyme as an example, we discuss how crowding can alter the equilibrium between pseudoknot and hairpin states of the same RNA molecule - a key aspect of crowder-RNA interactions. We summarize data showing that the crowding effect is significant only if the size of the spherical crowding particle is smaller than the radius of gyration of the RNA in the absence of crowding particles. The implication for function of the wild type and mutants of human telomerase is outlined by using a relationship between enzyme activity and its conformational equilibrium. In addition, we discuss the interplay between macromolecular crowding and ionic strength of the RNA buffer. Finally, we briefly review recent experiments which illustrate the connection between excluded volume due to macromolecular crowding and the thermodynamics of RNA folding.
Isothermal and adiabatic elastic constants from virial fluctuations

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We derive expressions for classical isothermal and adiabatic elastic constants for periodic systems with the boundary contributions included explicitly. The potential-dependent part of these expressions is written in terms of potential energies of atomic groups that make up the total potential energy. It is shown that in the thermodynamic limit, the Born term, which depends on the second derivatives of potential energy, can be expressed exactly in terms of equilibrium averages that involve two types of atomic-group virials. As a result, the new form of the Born term involves only first derivatives of either atomic-group or total potential energies. The derived elastic constant expressions involving the two forms of the Born terms are tested and compared using molecular-dynamics simulations of crystalline argon and silicon. For both materials, the elastic constants obtained using the two forms of the Born term are in good agreement. In particular, the new form of the Born term converges to the same value as the original Born term but at a slower rate. The results for silicon also agree well with the results from the previous molecular-dynamics studies.

description: The coupling between phonon and magnon is ubiquitous in magnetic materials and plays a crucial role in many aspects of magnetic properties, most notably in spintronics. Yet, this academically and technologically interesting problem still poses a severe challenge to a general understanding of the issue in certain materials. We report that Ni3TeO6 exhibits clear evidence of significant magnon-phonon coupling in both longitudinal thermal conductivity ($κ_{xx}$) and thermal Hall coefficient ($κ_{xy}$). The Debye-Callaway model, a phenomenological description for phonon heat conduction, can explain the measured magnetic field dependence of $κ_{xx}(H)$: phonon scattering from spin fluctuation in the paramagnetic phase and additional scattering due to magnon-phonon coupling in the collinear antiferromagnetic phase. We further suggest that a similar approach could be applied to understand the finite $κ_{xy}$ values in $Ni_3TeO_6$.

description: It was previously shown within chiral perturbation theory that the ground state of QCD in a sufficiently large magnetic field and at nonvanishing, but not too large, baryon chemical potential is a so-called chiral soliton lattice. The crucial ingredient of this observation was the chiral anomaly in the form of a Wess-Zumino-Witten term, which couples the baryon chemical potential to the magnetic field and the gradient of the neutral pion field. It was also shown that the chiral soliton lattice becomes unstable towards charged pion condensation at larger magnetic fields. We point out that this instability bears a striking resemblance to the second critical magnetic field of a type-II superconductor, however with the superconducting phase appearing upon increasing the magnetic field. The resulting phase has a periodically varying charged pion condensate that coexists with a neutral pion supercurrent. We construct this phase analytically in the chiral limit and show that it is energetically preferred. Just like an ordinary type-II superconductor, it exhibits a hexagonal array of magnetic flux tubes, and, due to the chiral anomaly, a spatially oscillating baryon number of the same crystalline structure.
