description: Constructing a quantum memory for a photonic entanglement is vital for realizing quantum communication and network. Besides enabling the realization of high channel capacity communication, entangled photons of high-dimensional space are of great interest because of many extended applications in quantum information and fundamental physics fields. Photons entangled in a two-dimensional space had been stored in different system, but there have been no any report on the storage of a photon pair entangled in a high-dimensional space. Here, we report the first experimental realization of storing an entangled orbital angular momentum (OAM) state through a far off-resonant two-photon transition (FORTPT) in a cold atomic ensemble. We reconstruct the matrix density of an OAM entangled state postselected in a two-dimensional subspace with a fidelity of 90.3%+/-0.8% and obtain the Clauser, Horne and Shimony and Holt inequality parameter S of 2.41+/-0.06 after a programmed storage time. All results clearly show the preservation of entanglement during the storage. Besides, we also realize the storage of a true-single-photon via FORTPT for the first time.

description: We consider the Skyrme model in the near-BPS limit. The BPS part is made of the sextic term plus a potential and the deformation is made of the standard massive Skyrme model controlled by a small parameter $ε\ll1$. In order to keep the perturbation under theoretical and computational control, we find a model for which BPS Skyrmions have compact support, henceforth denoted as compactons, and the spherically symmetric $B=1$ Skyrmion represents the most stable solution. We use the $ε$-expansion scheme to systematically calculate the corrections to the energy and compare with the exact numerical computations in the $B=1$ sector. Finally, we use the $ε$-expansion scheme to calculate the bound state of two $B=1$ Skyrmions and its binding energy, which corresponds, prior to quantization, to the deuteron in our model.

description: The study of nonlocality in scenarios that depart from the bipartite Einstein-Podolsky-Rosen setup is allowing to uncover many fundamental features of quantum mechanics. Recently, an approach to building network-local models based on machine learning lead to the conjecture that the family of quantum triangle distributions of [arXiv:1905.04902] did not admit triangle-local models in a larger range than the original proof. We prove part of this conjecture in the affirmative. Our approach consists in reducing the family of original, four-outcome distributions to families of binary-outcome ones, and then using the inflation technique to prove that these families of binary-outcome distributions do not admit triangle-local models. This constitutes the first successful use of inflation in a proof of quantum nonlocality in networks whose nonlocality could not be proved with alternative methods. Moreover, we provide a method to extend proofs of network nonlocality in concrete distributions of a parametrized family to continuous ranges of the parameter. In the process, we produce a large collection of network Bell inequalities for the triangle scenario with binary outcomes, which are of independent interest.

On the Event Structure of German bleiben
Creators: name: Schlücker, Barbara
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: The German copular verb bleiben („to remain“) is supposed to denote the continuation of a state. In this paper, I will argue that bleiben has next to that reading another reading, too, where it denotes a change of state and which seems to be equivalent to werden (“to become”). The aim of this paper is to present an event structure for bleiben which integrates both readings as well as to examine the event structures of werden and bleiben and to discuss whether the change-of-state meaning denoted by bleiben is equivalent to that of werden. I will show that this is not the case and that bleiben always denotes a state. An exception to this last point forms bleiben when it appears in the context of non-finite posture verbs. These bleiben-constructions, which are limited to a small number of posture verbs, denote events, too.

description: We consider the volume of the gauge orbit space for gauge fields on four-dimensional complex projective space. The analysis uses a parametrization of gauge fields where gauge transformations act homogeneously on the fields, facilitating a manifestly gauge-invariant analysis. The volume element contains a four-dimensional Wess-Zumino-Witten (WZW) action for a hermitian matrix-valued field. There is also a mass-like term for certain components of the gauge field. We discuss how the mass term could be related to results from lattice simulations as well as Schwinger-Dyson equations. We argue for a kinematic regime where the Yang-Mills theory can be approximated by the 4d-WZW theory. The result is suggestive of the instanton liquid picture of QCD. Further it is also indicative of the mechanism for confinement being similar to what happens in two dimensions.

Manners and Causation

Year: 2019

description: This paper is divided into two parts. In part one I apply a formal method for the establishment of cause-relations between events to cases involving manner modification. In the second part I argue that the status of a manner adverb with regard to its role in a cause-consequence sequent does not play a role for its formal representation at the sentential level. Instead, it influences a sentence’s information structure. In turn, this can influence the syntactic position of a manner adverb.

description: Efficient algorithms to generate candidate crystal structures with good stability properties can play a key role in data-driven materials discovery. Here we show that a crystal diffusion variational autoencoder (CDVAE) is capable of generating two-dimensional (2D) materials of high chemical and structural diversity and formation energies mirroring the training structures. Specifically, we train the CDVAE on 2615 2D materials with energy above the convex hull $ΔH_{\mathrm{hull}}< 0.3$ eV/atom, and generate 5003 materials that we relax using density functional theory (DFT). We also generate 14192 new crystals by systematic element substitution of the training structures. We find that the generative model and lattice decoration approach are complementary and yield materials with similar stability properties but very different crystal structures and chemical compositions. In total we find 11630 predicted new 2D materials, where 8599 of these have $ΔH_{\mathrm{hull}}< 0.3$ eV/atom as the seed structures, while 2004 are within 50 meV of the convex hull and could potentially be synthesized. The relaxed atomic structures of all the materials are available in the open Computational 2D Materials Database (C2DB). Our work establishes the CDVAE as an efficient and reliable crystal generation machine, and significantly expands the space of 2D materials.
Sozialräumliches Verständnis in einer ländlichen Gemeinde am Beispiel der Zentrumsgemeinde Hochdorf LU: Eine qualitative Forschungsarbeit mit Fokus auf Freiräume als Begegnungsort

description: Die vorliegende Forschungsarbeit beschäftigt sich mit der Relevanz sozialräumlicher Zugänge bei kommunalen Entwicklungsprozessen am Beispiel der Gemeinde Hochdorf LU. Sie untersucht die Bedeutung sozialräumlichem Verständnis bei der Bereitstellung und Gestaltung von öffentlichem Raum, welcher für die Gesamtbevölkerung niederschwellige Begegnung ermöglicht und Freizeit-Bedürfnisse wie Erholung und Bewegung befriedigt. Mit leitfadengestützten Expert*innen-Interviews in der Exekutive, der Raumplanung und der Kinder- und Jugendarbeit wurden Aussagen zu Verständnis und Erfahrung mit sozialräumlichen Aspekten sowie über das Potenzial, welches die Soziale Arbeit als Akteurin in der Gemeindeentwicklung haben könnte, erfasst. Die Ergebnisse deuteten darauf hin, dass sozialräumliche Perspektiven in der Verwaltung und in den strategischen Papieren der Raumplanung Hochdorf in der Vergangenheit wenig Beachtung gefunden haben. Um sicherzustellen, dass dieses Bewusstsein in der Gemeinde in Zukunft stärker vorhanden ist und personenunabhängig zur Umsetzung kommt, braucht es in der Verwaltung Vertretende mit Fachkenntnissen über gesellschaftliche, räumliche Zusammenhänge. Dabei kann die Soziale Arbeit Hand bieten, indem sie ihre beratende Tätigkeit innerhalb der Gemeindeverwaltung ausbaut. Mit einem zusätzlichen Auftrag, welcher die Interessen und Bedürfnisse der Nutzenden von Freiräumen abholt und beratend in die Behörden einbringt.

description: The current generation of galaxy simulations can resolve individual giant molecular clouds, the progenitors of dense star clusters. But the evolutionary fate of these young massive clusters, and whether they can become the old globular clusters (GCs) observed in many galaxies, is determined by a complex interplay of internal dynamical processes and external galactic effects. We present the first star-by-star $N$-body models of massive ($N\sim10^5-10^7$) star clusters formed in a FIRE-2 MHD simulation of a Milky Way-mass galaxy, with the relevant initial conditions and tidal forces extracted from the cosmological simulation. We select 895 ($\sim 30\%$) of the YMCs with $ > 6\times10^4M_{\odot}$ from Grudić et al.~2022 and integrate them to $z=0$ using the Cluster Monte Carlo Code, \texttt{CMC}. This procedure predicts a MW-like system with 148 GCs, predominantly formed during the early, bursty mode of star formation. Our GCs are younger, less massive, and more core-collapsed than clusters in the Milky Way or M31. This results from the assembly history and age-metallicity relationship of the host galaxy: younger clusters are preferentially born in stronger tidal fields and initially retain fewer stellar-mass black holes, causing them to lose mass faster and reach core collapse sooner than older GCs. Our results suggest that the masses and core/half-light radii of GCs are shaped not only by internal dynamical processes, but also by the specific evolutionary history of their host galaxies. These results emphasize that $N$-body studies with realistic stellar physics are crucial to understanding the evolution and present-day properties of GC systems.

description: We study extreme-value statistics of Brownian trajectories in one dimension. We define the maximum as the largest position to date and compare maxima of two particles undergoing independent Brownian motion. We focus on the probability P(t) that the two maxima remain ordered up to time t, and find the algebraic decay P ~ t^(-beta) with exponent beta=1/4. When the two particles have diffusion constants D1 and D2, the exponent depends on the mobilities, beta=(1/pi)arctan[sqrt(D2/D1)]. We also use numerical simulations to investigate maxima of multiple particles in one dimension and the largest extension of particles in higher dimensions.

A modal analysis of modal subordination
Creators: name: Van Rooy, Robert
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In this paper I will give a modal two-dimensional analysis of presupposition and modal subordination. I will think of presupposition as a non-veridical propositional attitude. This allows me to evaluate what is presupposed and what is asserted at different dimensions without getting into the binding problem. What is presupposed will be represented by an accessibility relation between possible worlds. The major part of the paper consists of a proposal to account for the dependence of the interpretation of modal expressions, i.e. modal subordination, in terms of an accessibility relation as well. Moreover, I show how such an analysis can be extended from the propositional to the predicate logical level.

The Semantics of Nouns Derived From Gradable Adjectives

Year: 2019

description: What semantics should we attribute to nouns like wisdom and generosity, which are derived from gradable adjectives? We show that, from a morphosyntactic standpoint, these nouns are mass nouns. This leads us to consider and answer the following questions. How are these nouns interpreted in their various uses? What formal representations may one associate with their interpretations? How do these depend on the semantics of the adjective? And where lies the semantic unity of nouns like wisdom and generosity with the more familiar concrete mass nouns, like wine and furniture?

Delocalization of electrons by cavity photons in transport through a quantum dot molecule

description: We present new results on cavity-photon-assisted electron transport through two lateral quantum dots embedded in a finite quantum wire. The double quantum dot system is weakly connected to two leads and strongly coupled to a single quantized photon cavity mode with initially two linearly polarized photons in the cavity. Including the full electron-photon interaction, the transient current controlled by a plunger-gate in the central system is studied by using quantum master equation. Without a photon cavity, two resonant current peaks are observed in the range selected for the plunger gate voltage: The ground state peak, and the peak corresponding to the first-excited state. The current in the ground state is higher than in the first-excited state due to their different symmetry. In a photon cavity with the photon field polarized along or perpendicular to the transport direction, two extra side peaks are found, namely, photon-replica of the ground state and photon-replica of the first-excited state. The side-peaks are caused by photon-assisted electron transport, with multiphoton absorption processes for up to three photons during an electron tunneling process. The inter-dot tunneling in the ground state can be controlled by the photon cavity in the case of the photon field polarized along the transport direction. The electron charge is delocalized from the dots by the photon cavity. Furthermore, the current in the photon-induced side-peaks can be strongly enhanced by increasing the electron-photon coupling strength for the case of photons polarized along the transport direction.

description: Recent neural network based Direction of Arrival (DoA) estimation algorithms have performed well on unknown number of sound sources scenarios. These algorithms are usually achieved by mapping the multi-channel audio input to the single output (i.e. overall spatial pseudo-spectrum (SPS) of all sources), that is called MISO. However, such MISO algorithms strongly depend on empirical threshold setting and the angle assumption that the angles between the sound sources are greater than a fixed angle. To address these limitations, we propose a novel multi-channel input and multiple outputs DoA network called MIMO-DoAnet. Unlike the general MISO algorithms, MIMO-DoAnet predicts the SPS coding of each sound source with the help of the informative spatial covariance matrix. By doing so, the threshold task of detecting the number of sound sources becomes an easier task of detecting whether there is a sound source in each output, and the serious interaction between sound sources disappears during inference stage. Experimental results show that MIMO-DoAnet achieves relative 18.6% and absolute 13.3%, relative 34.4% and absolute 20.2% F1 score improvement compared with the MISO baseline system in 3, 4 sources scenes. The results also demonstrate MIMO-DoAnet alleviates the threshold setting problem and solves the angle assumption problem effectively.

description: We discuss the formalism of two Higgs doublet model type III with CP violation from CP-even CP-odd mixing in the neutral Higgs bosons. The flavor changing interactions among neutral Higgs bosons and fermions are presented at tree level in this type of model. These assumptions allow the study rare top decays mediated by neutral Higgs bosons, particularly we are interested in $t\rightarrow c l^+l^-$. For this process we estimated upper bounds of the branching ratios $\textrm{Br}(t\rightarrow c τ^+τ^-)$ of the order of $10^{-9}\sim 10^{-7}$ for a neutral Higgs boson mass of 125 GeV and $\tanβ=1$, 1.5, 2, 2.5. For the case of $t\rightarrow c τ^+τ^-$ the number of possible events is estimated from 1 to 10 events which could be observed in future experiments at LHC with a luminosity of 300 $\textrm{fb}^{-1}$ and 14 GeV for the energy of the center of mass. Also we estimate that the number of events for the process $t\rightarrow c l^+l^-$ in different scenarios is of order of $2500$.

description: Many extensions of the standard model (SM) predict the existence of axion-like particles and/or dark Higgs in the sub-GeV scale. Two new sub-GeV particles, a scalar and a pseudoscalar, produced through the Higgs boson exotic decays, are investigated. The decay signatures of these two new particles with highly collimated photons in the final states are discriminated from the ones of SM backgrounds using the Convolutional Neural Networks and Boosted Decision Trees techniques. The sensitivities of searching for such new physics signatures at the Large Hadron Collider are obtained.

description: We consider an overdamped run-and-tumble particle in two dimensions, with self propulsion in an orientation that stochastically rotates by 90 degrees at a constant rate, clockwise or counter-clockwise with equal probabilities. In addition, the particle is confined by an external harmonic potential of stiffness $μ$, and possibly diffuses. We find the exact time-dependent distribution $P\left(x,y,t\right)$ of the particle's position, and in particular, the steady-state distribution $P_{\text{st}}\left(x,y\right)$ that is reached in the long-time limit. We also find $P\left(x,y,t\right)$ for a "free" particle, $μ=0$. We achieve this by showing that, under a proper change of coordinates, the problem decomposes into two statistically-independent one-dimensional problems, whose exact solution has recently been obtained. We then extend these results in several directions, to two such run-and-tumble particles with a harmonic interaction, to analogous systems of dimension three or higher, and by allowing stochastic resetting.

Middles as Disposition Ascriptions
Creators: name: Lekakou, Marika
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Any analysis of middles has to account for the fact that across languages there is variation in their syntax. English and Dutch employ an unergative verb, whereas in French and Greek it is passives that can encode the middle interpretation. I propose to treat ‘middle’ as the targeted interpretation, which different languages express in different ways, depending on the means available to them with respect to encoding genericity. I qualify middles as disposition ascriptions to the internal argument, and argue that their core properties follow from this characterization.

description: The modeling of multi-phase flow is very challenging, given the range of scales as well as the diversity of flow regimes that one encounters in this context. We revisit the discrete equation method (DEM) for two-phase flow in the absence of heat conduction and mass transfer. We analyze the resulting probability coefficients and prove their local convexity, rigorously establishing that our version of DEM can model different flow regimes ranging from the disperse to stratified (or separated) flow. Moreover, we reformulate the underlying mesoscopic model in terms of an one-parameter family of PDEs that interpolates between different flow regimes. We also propose two sets of procedures to enforce relaxation to equilibrium. We perform several numerical tests to show the flexibility of the proposed formulation, as well as to interpret different model components. The one-parameter family of PDEs provides an unified framework for modeling mean quantities for a multiphase flow, while at the same time identifying two key parameters that model the inherent uncertainty in terms of the underlying microstructure.

description: Circular dichroism (CD), i.e. the differential response of a system to left and right circularly polarized light, is one of the only techniques capable of providing morphological information of certain samples. In biology, for instance, CD spectroscopy is widely used to study the structure of proteins. More recently, it has also been used to characterize metamaterials and plasmonic structures. Typically, CD can only be observed in chiral objects. Here, we present experimental results showing that a non-chiral sample such as a sub-wavelength circular nano-aperture can produce giant CD when a vortex beam is used to excite it. These measurements can be understood by studying the symmetries of the sample and the total angular momentum that vortex beams carry. Our results show that CD can provide a wealth of information about the sample when combined with the control of the total angular momentum of the input field.
Scope fo Focus Particles: Abstract Only in Korean
Creators: name: Lee, Youngjoo
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: The focus particle man ‘only’ in Korean shows different scopal behavior depending upon ist syntactic environment. This non-uniform scope pattern cannot be accounted for if the particle is a scope-bearing element. This paper argues that the particle man is not a scope-bearing element, but an agreement morpheme that indicates the presence of a null head ONLY. Under this proposal, the particle man does not carry the exhaustive meaning of only, but the null head does. Therefore, it is the position of the ONLY head, not that of the particle, that determines the scope relation with respect to other quantificational elements. This paper also claims that there is a strong correlation between syntax and morphology (cf. Baker’s Mirror Principle). Thus, the relative order among the particle, case marker, and postposition reflects the hierarchy of corresponding functional heads. This helps detect the position of the ONLY head. The proposed analysis accounts for the scope patterns without making special stipulations about man-phrases.

description: Two-dimensional (2D) materials have been a central focus of recent research because they host a variety of properties, making them attractive both for fundamental science and for applications. It is thus crucial to be able to identify accurately and efficiently if bulk three-dimensional (3D) materials are formed by layers held together by a weak binding energy that, thus, can be potentially exfoliated into 2D materials. In this work, we develop a machine-learning (ML) approach that, combined with a fast preliminary geometrical screening, is able to efficiently identify potentially exfoliable materials. Starting from a combination of descriptors for crystal structures, we work out a subset of them that are crucial for accurate predictions. Our final ML model, based on a random forest classifier, has a very high recall of 98\%. Using a SHapely Additive exPlanations (SHAP) analysis, we also provide an intuitive explanation of the five most important variables of the model. Finally, we compare the performance of our best ML model with a deep neural network architecture using the same descriptors. To make our algorithms and models easily accessible, we publish an online tool on the Materials Cloud portal that only requires a bulk 3D crystal structure as input. Our tool thus provides a practical yet straightforward approach to assess whether any 3D compound can be exfoliated into 2D layers.

description: We present an overview of recent developments in the numerical solution of Horndeski gravity theories, which are the class of all scalar-tensor theories of gravity that have second order equations of motion. We review several methods that have been used to establish well-posed initial value problems for these theories, and discuss well-posed formulations of the constraint equations. We also discuss global aspects of exact, strongly coupled solutions to some of Horndeski gravity theories: the formation of shocks, the loss of hyperbolicity, and the formation of naked curvature singularities. Finally we discuss numerical solutions to binary black hole and neutron star systems for several Horndeski theories.

description: Multi-step-ahead time series prediction is one of the most challenging research topics in the field of time series modeling and prediction, and is continually under research. Recently, the multiple-input several multiple-outputs (MISMO) modeling strategy has been proposed as a promising alternative for multi-step-ahead time series prediction, exhibiting advantages compared with the two currently dominating strategies, the iterated and the direct strategies. Built on the established MISMO strategy, this study proposes a particle swarm optimization (PSO)-based MISMO modeling strategy, which is capable of determining the number of sub-models in a self-adaptive mode, with varying prediction horizons. Rather than deriving crisp divides with equal-size s prediction horizons from the established MISMO, the proposed PSO-MISMO strategy, implemented with neural networks, employs a heuristic to create flexible divides with varying sizes of prediction horizons and to generate corresponding sub-models, providing considerable flexibility in model construction, which has been validated with simulated and real datasets.

The Quantificational Function of the Japanese Numeral Classifier
Creators: name: Kobuchi-Philip, Mana
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper presents a new quantificational analysis of the Japanese numeral quantifier (NQ) construction. It is proposed that the classifier within the NQ functions as the domain of quantification for the numeral, denoting a set of atomic individuals. This accounts for the predominant distributive reading of the floating NQ sentence, both with object classifiers and event classifiers, as a direct consequence of the atomicity condition of the classifier denotation. The analysis correctly predicts that, unlike the floating NQ, the non-floating NQ will show a collective/distributive ambiguity because it forms a plural term, which can always be interpreted as a group individual or as a sum of individuals. The analysis also provides a semantic account of the well-known classifier-NP agreement phenomenon.

The Referential Properties of Dutch Pronouns and Demonstratives: Is Salience Enough?
Creators: name: Kaiser, Elsi
name: Trueswell, John
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: According to many researchers, the form of referring expressions is connected to the accessibility/topicality of their referents: The most reduced referring expressions refer to highly accessible referents, whereas fuller expressions refer to less accessible referents. Thus, in languages with full and reduced pronouns, full forms are said to refer to less accessible referents. In this paper, we investigate these claims by looking at Dutch, which has full and reduced pronouns and demonstratives. We report here the results of a sentence-completion study as well as an eye-tracking experiment that we conducted, and argue that the results are only partly compatible with a straightforward accessibility-based approach to referential form. More specifically, our results suggest that the full vs. reduced pronoun choice is not triggered by referent salience, but the choice of a demonstrative over a pronoun is. Corpus examples indicate that use of full form of pronouns may in fact be prompted by contrast. Overall, these results – as well as work on Finnish and Estonian (Kaiser 2003) – show that different anaphoric forms within one language can be sensitive to different factors, and their referential properties cannot be captured by a unified notion of salience.

description: The alpha clustering in the 10Be and 12Be has been studied within the framework of the real-time evolution method (REM). By using the effective interaction tuned to reproduce the charge radii and the threshold energies, we have evaluated the alpha reduced width amplitude (RWA) and spectroscopic factor (S-factor) for the ground and excited states. With several improvements made in this work, comparing with our previous calculations, larger rate of clustering results are obtained for the 10Be and 12Be with correct asymptotic at large distance.
Ingredients of a Semantic Theory of Contrastive Topics
Creators: name: Gyuris, Beáta
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: The paper investigates four phenomena having to do with the interpretation of Hungarian sentences with contrastive topics (CTs), including the apparent wide scope as well as narrow scope readings of CTs, the lack of interpretations for particular, otherwise well-formed sentences with a CT, and the predictability of collective versus distributive readings for plural NPs in CT position. Some previous theories are reviewed, and claimed to be unable to handle all of the above phenomena simultaneously. The paper argues that the first puzzle should be handled along the lines of Jacobs (1997), the third and the fourth along the lines of Büring (1997), and it proposes a new approach to explain the second one.

description: In this paper we address the problem of classification of simple weight modules over weak generalized Weyl algebras of rank one. The principal difference between weak generalized Weyl algebras and generalized weight algebras is that weak generalized Weyl algebras are defined using an endomorphism rather than an automorphism of a commutative ring $R$. We reduce classification of simple weight modules over weak generalized Weyl algebras to description of the dynamics of the action of the above mentioned endomorphism on the set of maximal ideals. We also describe applications of our results to the study of generalized Heisenberg algebras.

description: We provide an accurate comparison, against large cosmological $N$-body simulations, of different prescriptions for modelling nonlinear matter power spectra in the presence of massive neutrinos and dynamical dark energy. We test the current most widely used approaches: fitting functions (HALOFIT and HMcode), the halo-model reaction (ReACT) and emulators (baccoemu and EuclidEmulator2). Focussing on redshifts $z\leq2$ and scales $k\lesssim 1 \ h/$Mpc (where the simulation mass resolution provides $\sim 1\%$ accuracy), we find that HMcode and ReACT considerably improve over the HALOFIT prescriptions of Smith and Takahashi (both combined with the Bird correction), with an overall agreement of 2\% for all the cosmological scenarios considered. Concerning emulators, we find that, especially at low redshifts, EuclidEmulator2 remarkably agrees with the simulated spectra at $\lesssim 1\%$ level in scenarios with dynamical dark energy and massless neutrinos, reaching a maximum difference of $\sim 2\%$ at $z=2$. baccoemu has a similar behaviour as EuclidEmulator2, except for a couple of dark energy models. In cosmologies with massive neutrinos, at $z=0$ all the nonlinear prescriptions improve their agreement with respect to the massless neutrino case, except for the Bird and TakaBird models which, however, are not tailored to $w_0$--$w_a$ models. At $z>0$ we do not find a similar improvement when including massive neutrinos, probably due to the lower impact of neutrino free-streaming at higher redshifts; rather at $z=2$ EuclidEmulator2 exceeds $2\%$ agreement for some dark energy equation of state. When considering ratios between the matter power spectrum computed in a given cosmological model and its $Λ$CDM counterpart, all the tested prescriptions agree with simulated data, at sub-percent or percent level, depending on $z$.

description: We study a quantum Hot Big Bang in the connection representation, with a matter constant of motion m whose conjugate defines time. Superpositions in m induce a unitary inner product. The wavefunction reveals a resolution of the singularity problem without new physics or supplementary boundary conditions. Backtracking in time, the probability peak eventually halts at a maximum curvature, its height dropping thereafter while a symmetric contracting peak rises. The Big Bang is replaced by a superposition of contracting and expanding regular Universes. We contrast these findings with the situation in the metric representation, where boundary conditions at the singularity are needed for unitary evolution.

Given that nanoparticles and thin films of CsEuCl$_3$ have been reported to order ferromagnetically at a similar temperature, our observation of antiferromagnetic ordering in CsEuBr$_3$ and CsEuCl$_3$ expands the possible applications of halide perovskites to now include spintronic devices where both ferromagnetic and antiferromagnetic devices can be fabricated from a single material. The conclusion that CsEuCl$_3$ can be used as a switchable magnetic material is also supported by our density-functional theory calculations.
