Modals and Tense
Creators: name: Eide, Kristin M.
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Several recent works on modals and tense argue that epistemic modals and similar types of predicates are deprived of temporal properties. This article takes a different stand. Although epistemic modals typically express what may be dubbed “unchanging truths”, there exist examples to demonstrate that these types of predicates are still able to express a shift in temporal reference. This being the case, epistemic modals cannot be “outside the scope of tense altogether”, as claimed by Cinque (1999) and many others. This is as expected on the tense system I outline here, since I defend the idea that any verb is inherently temporal; specifically, that every verb contains a tense element, partaking in a temporal chain where only the topmost member is finite; the remaining members are non-finite. By means of this system, I investigate the temporal construal of root and epistemic modal constructions.

description: A standard-form Wadati-Konno-Ichikawa(WKI) type integrable hierarchy is derived from a corresponding matrix spectral problem associated with the Lie algebra sl(2, R). Each equation in the resulting hierarchy has a bi-Hamiltonian structure furnished by the trace identity. Then, the higher grading affine algebraic construction of some special cases is proposed. We also show that eneralized short pulse equation arises naturally from the negative WKI flow.

description: The thermoelectric properties of Sr0.61Ba0.39Nb2O6 ceramics, reduced in different conditions, were investigated in the temperature region from 323 K to 1073 K. The electrical transport behaviors of the samples are dominated by the thermal-activated polaron hopping, the Fermi glass behavior, and the Anderson localized behavior from low temperatures to high temperatures, respectively. The lattice thermal conductivity presents a plateau at high temperatures, indicating a glass-like thermal conduction behavior. Both the thermoelectric power factor and the thermal conductivity increase with the increasing degree of oxygen-reduction. Taking these two factors into account, the oxygen-reduction can still contribute to promoting the thermoelectric figure of merit. The highest ZT value (~0.19 at 1073 K) is obtained in the heaviest oxygen reduced sample.

description: We consider the behavior of Fermi atoms on optical superlattices with two-well structure of each node. Fermions on such lattices serve as an analog simulator of Fermi type Hamiltonian. We derive a mapping between fermion quantum ordering in the optical superlattices and the spin-orbital physics developed for degenerate $d$-electron compounds. The appropriate effective spin-orbital model appears to be the modification of the Kugel-Khomskii Hamiltonian. We show how different ground states of this Hamiltonian correspond to particular spin-pseudospin arrangement patterns of fermions on the lattice. The dependence of fermion arrangement on phases of complex hopping amplitudes is illustrated.

Topical Restriction and Answerhood
Creators: name: Dekker, Paul
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: Information structure is the term designating a very lively and active branch of work, which deals with various topics such as anaphora, topical restriction, questions, congruence and exhaustification. This work tends to diverge in many directions which hardly can be seen to be compatible with one another. In this paper we attempt to improve the situation by trying to develop the minimal formal tools required to study the logical properties of the various issues involved and integrate them step by step. We successively deal with anaphoric connections between pronouns and other terms in terms of individual satisfaction by possible witnesses; with questions and topics in terms of sets of possible witnesses; with topical restriction and answerhood in terms of topical satisfaction; we conclude with a compositional deconstruction of Henk Zeevat’s exhaustification operation.

description: Quantum capacities are fundamental quantities that are notoriously hard to compute and can exhibit surprising properties such as superadditivity. Thus, a vast amount of literature is devoted to finding tight and computable bounds on these capacities. We add a new viewpoint by giving operationally motivated bounds on several capacities, including the quantum capacity and private capacity of a quantum channel and the one-way distillable entanglement and private key of a quantum state. These bounds are generally phrased in terms of capacity quantities involving the complementary channel or state. As a tool to obtain these bounds, we discuss partial orders on quantum channels and states, such as the less noisy and the more capable order. Our bounds help to further understand the interplay between different capacities, as they give operational limitations on superadditivity and the difference between capacities in terms of the information-theoretic properties of the complementary channel or state. They can also be used as a new approach towards numerically bounding capacities, as discussed with some examples.

Interpreting ‘be’
Creators: name: Cann, Ronnie
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper proposes an approach to the interpretation of copular sentences in English that analyses be as a one-place predicate with underspecified semantic content. The interpretation of a copula clause is determined through the interaction of syntactic and pragmatic processes and depends on the properties of expressions collocated with be and general contextual factors, both local and non-local. Analyses are provided for predicational, specificational and equative sentences using the framework of Dynamic Syntax.

description: We propose a new beam dump experiment at a future TeV-scale muon collider. A beam dump would be an economical and effective way to increase the discovery potential of the collider complex in a complementary regime. In this work we consider vector models such as the dark photon and $L_μ-L_τ$ gauge boson as new physics candidates and explore which novel regions of parameter space can be probed with a muon beam dump. We find that for the dark photon model, we gain sensitivity in the moderate mass (MeV - GeV) range at both higher and lower couplings compared to existing and proposed experiments, and gain access to previously untouched areas of parameter space of the $L_μ-L_τ$ model.

description: In this study, we propose a simple and effective preprocessing method for subword segmentation based on a data compression algorithm. Compression-based subword segmentation has recently attracted significant attention as a preprocessing method for training data in Neural Machine Translation. Among them, BPE/BPE-dropout is one of the fastest and most effective method compared to conventional approaches. However, compression-based approach has a drawback in that generating multiple segmentations is difficult due to the determinism. To overcome this difficulty, we focus on a probabilistic string algorithm, called locally-consistent parsing (LCP), that has been applied to achieve optimum compression. Employing the probabilistic mechanism of LCP, we propose LCP-dropout for multiple subword segmentation that improves BPE/BPE-dropout, and show that it outperforms various baselines in learning from especially small training data.

Arbitrary Readings of 3pl Pronominals
Creators: name: Cabredo Hofherr, Patricia
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In the generative literature antecedentless readings of 3pl pronouns have been referred to as arbitrary. The present article argues that antecedentless readings are not a unitary phenomenon and proposes to distinguish 5 types of antecedentless readings for 3pl pronouns. I propose that the antecedentless readings depend on a deficient form of 3pl agreement that allows a non-anaphoric reading and only contributes the feature [+human]. I further propose that the different readings rely on two possible translations of 3pl pronouns combined with different mechanisms of content identification.

description: Ballistic neutron guides are efficient for neutron transport over long distances, and in particular elliptically shaped guides have received much attention lately. However, elliptic neutron guides generally deliver an inhomogeneous divergence distribution when used with a small source, and do not allow kinks or curvature to avoid a direct view from source to sample. In this article, a kinked double-elliptic solution is found for neutron transport to a small sample from a small (virtual) source, as given e.g. for instruments using a pinhole beam extraction with a focusing feeder. A guide consisting of two elliptical parts connected by a linear kinked section is shown by VITESS simulations to deliver a high brilliance transfer as well as a homogeneous divergence distribution while avoiding direct line of sight to the source. It performs better than a recently proposed ellipse-parabola hybrid when used in a ballistic context with a kinked or curved central part. Another recently proposed solution, an analytically determined non-linear focusing guide shape, is applied here for the first time in a kinked and curved ballistic context. The latter is shown to yield comparable results for long wavelength neutrons as the guide design found here, with a larger inhomogeneity in the divergence but higher transmission of thermal neutrons. It needs however a larger (virtual) source and might be more difficult to build in a real instrument.
A Reinforcement Approach for Detecting P2P Botnet Communities in Dynamic Communication Graphs

description: Peer-to-peer (P2P) botnets use decentralized command and control networks that make them resilient to disruptions. The P2P botnet overlay networks manifest structures in mutual-contact graphs, also called communication graphs, formed using network traffic information. It has been shown that these structures can be detected using community detection techniques from graph theory. These previous works, however, treat the communication graphs and the P2P botnet structures as static. In reality, communication graphs are dynamic as they represent the continuously changing network traffic flows. Similarly, the P2P botnets also evolve with time, as new bots join and existing bots leave either temporarily or permanently. In this paper we address the problem of detecting such evolving P2P botnet communities in dynamic communication graphs. We propose a reinforcement-based approach, suitable for large communication graphs, that improves precision and recall of P2P botnet community detection in dynamic communication graphs.
Extremely quick thermalization in a macroscopic quantum system for a typical nonequilibrium subspace

description: The fact that macroscopic systems approach thermal equilibrium may seem puzzling, for example, because it may seem to conflict with the time-reversibility of the microscopic dynamics. We here prove that in a macroscopic quantum system for a typical choice of "nonequilibrium subspace", any initial state indeed thermalizes, and in fact does so very quickly, on the order of the Boltzmann time $τ_\mathrm{B}:=h/(k_\mathrm{B}T)$. Therefore what needs to be explained is, not that macroscopic systems approach equilibrium, but that they do so slowly.

description: The field of quantum communications promises the faithful distribution of quantum information, quantum entanglement, and absolutely secret keys, however, the highest rates of these tasks are fundamentally limited by the transmission distance between quantum repeaters. The ultimate end-to-end rates of quantum communication networks are known to be achievable by an optimal entanglement distillation protocol followed by teleportation. In this work, we give a practical design for this achievability. Our ultimate design is an iterative approach, where each purification step operates on shared entangled states and detects loss errors at the highest rates allowed by physics. As a simpler design, we show that the first round of iteration can purify completely at high rates. We propose an experimental implementation using linear optics and photon-number measurements which is robust to inefficient operations and measurements, showcasing its near-term potential for real-world practical applications.

Predicate Logic with Barriers and its Locality Effects
Creators: name: Butler, Alastair
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper presents a system of interpretation for a language of first order predicate logic with barriers (PLB), which builds on Dekker’s (2002) Predicate Logic with Anaphora (PLA). The novel ingredient of the system is a barrier operator. This moves value information from the assignment function to the discourse context, with the result of producing locality effects. These are shown to match up with a range of locality effects found in natural language, including binding (condition A, B and C) effects, constraints on different types of movement (A-bar and A), and strong crossover violations.

description: Upcoming and planned experiments combining increasingly intense lasers and energetic particle beams will access new regimes of nonlinear, relativistic, quantum effects. This improved experimental capability has driven substantial progress in QED in intense background fields. We review here the advances made during the last decade, with a focus on theory and phenomenology. As ever higher intensities are reached, it becomes necessary to consider processes at higher orders in both the number of scattered particles and the number of loops, and to account for non-perturbative physics (e.g. the Schwinger effect), with extreme intensities requiring resummation of the loop expansion. In addition to increased intensity, experiments will reach higher accuracy, and these improvements are being matched by developments in theory such as in approximation frameworks, the description of finite-size effects, and the range of physical phenomena analysed. Topics on which there has been substantial progress include: radiation reaction, spin and polarisation, nonlinear quantum vacuum effects and connections to other fields including physics beyond the Standard Model.

description: An accurate determination of the effective electric field (Eeff) in YbF is important, as it can be combined with the results of future experiments to give an improved new limit for the electric dipole moment of the electron. We report a relativistic coupled-cluster calculation of this quantity in which all the core electrons were excited. It surpasses the approximations made in the previous reported calculations. We obtain a value of 23.1 GV/cm for Eeff in YbF with an estimated error of less than 10%. The crucial roles of the basis sets and the core excitations in our work are discussed.
Is there any Difference between Contrastive Focus and Information Focus?
Creators: name: Brunetti, Lisa
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper challenges the current assumption that there are two different types of focus in Italian: a ‘contrastive’ focus and an ‘information’ focus. I claim that the distinction does not hold at any level of the grammar. From an interpretive point of view, I show that there isn’t a focus expressing non-presupposed information and one expressing exhaustive identification, but only one focus expressing non-presupposed information. From a prosodic point of view, I argue that the rules of accent placement and the relation between accent and the focus domain are always the same. From a syntactic point of view, I show that a focus can always move to the left and that it always displays operator-like properties.

description: MadJax is a tool for generating and evaluating differentiable matrix elements of high energy scattering processes. As such, it is a step towards a differentiable programming paradigm in high energy physics that facilitates the incorporation of high energy physics domain knowledge, encoded in simulation software, into gradient based learning and optimization pipelines. MadJax comprises two components: (a) a plugin to the general purpose matrix element generator MadGraph that integrates matrix element and phase space sampling code with the JAX differentiable programming framework, and (b) a standalone wrapping API for accessing the matrix element code and its gradients, which are computed with automatic differentiation. The MadJax implementation and example applications of simulation based inference and normalizing flow based matrix element modeling, with capabilities enabled uniquely with differentiable matrix elements, are presented.

description: A reliable source of identical (indistinguishable) photons is a prerequisite for exploiting interference effects, which is a necessary component for linear optical based quantum computing, and applications thereof such as Boson sampling. Generally speaking, the degree of distinguishability will determine the efficacy of the particular approach, for example by limiting the fidelity of constructed resource states, or reducing the complexity of an optical circuits output distribution. It is therefore of great practical relevance to engineer heralded sources of highly pure and indistinguishable photons. Inspired by magic state distillation, we present a protocol using standard linear optics which can be used to increase the indistinguishability of a photon source, to arbitrary accuracy. In particular, in the asymptotic limit of small error $ε$, to reduce the error to $ε' < ε$ requires $O((ε/ε')^2)$ photons. We demonstrate the scheme is robust to detection and control errors in the optical components, and discuss the effect of other error sources.

Exceptional-Scope Indefinites and Domain Restriction
Creators: name: Breheny, Richard
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: This paper argues that the apparent exceptional scope behaviour of indefinites can be accounted for just by supposing a unitary analysis of indefinites as existential quantified noun phrases. It is argued that it is consistent with the meaning and use of quantificational indefinite noun phrases that, on occasion, their domain is implicitly contextually restricted by an identifying condition which the speaker has in mind. In order to explicate what the idea of having such things ‘in mind’ might amount to, some proposals in Perry (2001) are drawn on. The account is extended to deal with intermediate scope effects.

In this way they can be sensitive to the alternatives any and or introduce in their scope.

Future WH-Clauses in DP-Positions
Creators: name: Agouraki, Yoryia
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: The paper presents Future wh-clauses (FWHCs), a previously unnoticed type of whclauses, and discusses its key properties. Namely, selection by a small class of accomplishment predicates, restriction for Future Tense in the wh-clause, NP-type nonpresuppositional semantics, where the FWHC denotes an individual defined by a unique property, strong feeling of current relevance associated with the selecting predicates, and compatibility of the selecting predicates with ‘since’-adverbials. It is argued (a) that FWHCs are interpreted as intensional definite DPs; (b) that in ‘selecting’ FWHCs the matrix predicates are used intensionally; and (c) that the selecting predicates have a ‘perfect’ component in their decomposed lexical structure. FWHCs are distinguished from Irrealis Free Relatives.

description: We study the conditions of amplitude death in a network of delay-coupled limit cycle oscillators by including time-varying delay in the coupling and self-feedback. By generalizing the master stability function formalism to include variable-delay connections with high-frequency delay modulations (i.e., the distributed-delay limit), we analyze the regimes of amplitude death in a ring network of Stuart-Landau oscillators and demonstrate the superiority of the proposed method with respect to the constant delay case. The possibility of stabilizing the steady state is restricted by the odd-number property of the local node dynamics independently of the network topology and the coupling parameters.

description: In this paper we discuss a particular type of comparatives, that we call reflexive comparatives. These reflexive comparatives have the property that they compare an object with itself, but with respect to different temporal, spatial or scalar indices. We argue that this property can be viewed as the optimal outcome of a conflict between two general constraints on the arguments of a semantic relation. A semantics of reflexive comparatives is proposed which is based on paths in scalar and other domains.

description: We study various categories of Whittaker modules over a type I Lie superalgebra realized as cokernel categories that fit into the framework of properly stratified categories. These categories are the target of the Backelin functor $Γ_ζ$. We show that these categories can be described, up to equivalence, as Serre quotients of the BGG category $\mathcal O$ and of certain singular categories of Harish-Chandra $(\mathfrak g,\mathfrak g_{\bar 0})$-bimodules. We also show that $Γ_ζ$ is a realization of the Serre quotient functor. We further investigate a $q$-symmetrized Fock space over a quantum group of type A and prove that, for general linear Lie superalgebras our Whittaker categories, the functor $Γ_ζ$ and various realizations of Serre quotients and Serre quotient functors categorify this $q$-symmetrized Fock space and its $q$-symmetrizer. In this picture, the canonical and dual canonical bases in this $q$-symmetrized Fock space correspond to tilting and simple objects in these Whittaker categories, respectively.

Overlaying Contexts of Interpretation

description: The paper proposes a theory of the context of interpretation that is always an information state with some extra structure. It departs from existing models in going for uniformity and in the way uniformity is achieved: the context is the local context together with as much of the embedding context as can be added without losing consistency. The paper gives a formalisation, shows a number of applications of this idea and expands on the connection between this idea of the context and intentional identity.

Higher-order symmetry energy of nuclear matter and the inner edge of neutron star crusts

description: The parabolic approximation to the equation of state of the isospin asymmetric nuclear matter (ANM) is widely used in the literature to make predictions for the nuclear structure and the neutron star properties. Based on the realistic M3Y-Paris and M3Y-Reid nucleon-nucleon interactions, we investigate the effects of the higher-order symmetry energy on the proton fraction in neutron stars and the location of the inner edge of their crusts and their core-crust transition density and pressure, thermodynamically. Analytical expressions for different-order symmetry energy coefficients of ANM are derived using the realistic interactions mentioned above. It is found that the higher-order terms of the symmetry energy coefficients up to its eighth-order (E$_{sym8}$) contributes substantially to the proton fraction in $β$ stable neutron star matter at different nuclear matter densities, the core-crust transition density and pressure. Even by considering the symmetry energy coefficients up to E$_{sym8}$, we obtain a significant change of about 40$\%$ in the transition pressure value from the one based on the exact equation of state. Using equations of state based on both Paris and Reid effective interactions which provide saturation incompressibility of symmetric nuclear matter in the range of 220 MeV$\leq$K$_0$$\leq$270 MeV, we estimate the ranges 0.090 fm$^{-3}$$\leq$$ρ_t$$\leq$0.095 fm$^{-3}$ and 0.49 MeV fm$^{-3}$$\leq$P$_t$$\leq$ 0.59 MeV fm$^{-3}$ for the liquid core-solid crust transition density and pressure, respectively. The corresponding range of the proton fraction at this transition density range is found to be 0.029$\leq$x$_{p(t)}$$\leq$0.032.

description: We consider the initial value problem for cubic derivative nonlinear Schrödinger equations possessing weakly dissipative structure in one space dimension. We show that the small data solution decays like $O((\log t)^{-1/4})$ in $L^2$ as $t\to +\infty$. Furthermore, we find that this $L^2$-decay rate is optimal by giving a lower estimate of the same order.

description: Recent observations by the $Fermi$ Gamma-ray Space Telescope have confirmed the existence of thermal and non-thermal components in the prompt photon spectra of some Gamma-ray bursts (GRBs). Through an analysis of six bright Fermi GRBs, we have discovered a correlation between the observed photospheric and non-thermal $γ$-ray emission components of several GRBs using a physical model that has previously been shown to be a good fit to the Fermi data. From the spectral parameters of these fits we find that the characteristic energies, $E_{\rm p}$ and $kT$, of these two components are correlated via the relation $E_{\rm p} \propto T^α$ which varies from GRB to GRB. We present an interpretation in which the value of index $α$ indicates whether the jet is dominated by kinetic or magnetic energy. To date, this jet composition parameter has been assumed in the modeling of GRB outflows rather than derived from the data.

description: (14) Asterocarpa humilis (Heller, 1878)
Status in U.K. – non-native.
The “compass sea squirt” Asterocarpa humilis has been recorded at several monitoring programme sites, each year since 2014, from rapid assessment and scrape samples. It has been found on the Gutter Sound navigation buoy and mooring buoys in Ore Bay, it has also been found in both Stromness and Kirkwall marinas.
Asterocarpa humilis was first recorded in England in 2009, in Wales in 2011 (Bishop et al. 2013) and in Scotland (Kerrera Marina, Oban) in 2013 (Nall et al. 2015). The records presented here from 2014 are the first from Orkney.

Degenerate Plurals

Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: We argue that the wh-mo construction in Japanese should be analyzed as an i-sum denoting degenerate plural, distinct from group denoting true plurals and from universal quantifiers. Universal quantification-like behavior we derive from an optional distributive operator that can occur with plurals as well as with wh-mo expressions. The optionality of this operator makes it possible to account for quantificational variability in examples containing adverbs of quantification as well.

Ab initio guided minimal model for the "Kitaev" material BaCo$_2$(AsO$_4$)$_2$: Importance of direct hopping, third-neighbor exchange and quantum fluctuations

description: By considering two {\it ab initio}-based complementary approaches, we analyze the electronic structure and extract effective spin models of BaCo$_2$(AsO$_4$)$_2$, a honeycomb material which has been proposed as a candidate for Kitaev physics. Both methods show that the dominant direct hopping makes the bond-dependent Kitaev term negligible averting the material away from the sought-after spin-liquid regime. As a result, we present a simple three-parameter exchange model to describe the interactions of the lowest doublet of the honeycomb cobaltate BaCo$_2$(AsO$_4$)$_2$. Remarkably, it is the third-neighbor interactions, both isotropic and anisotropic, that are responsible for the standout double-zigzag ground state of BaCo$_2$(AsO$_4$)$_2$, stabilized by quantum fluctuations. A significantly large third-nearest neighbor hopping, observed in {\it ab initio}, supports the importance of the third-neighbor interactions in the stabilization of the unique ground state of BaCo$_2$(AsO$_4$)$_2$.

Loop correction to the scalar Casimir energy density and generation of topological mass due to a helix boundary condition in a scenario with Lorentz violation

description: In this paper the effective potential approach in quantum field theory is used in order to investigate self-interaction loop correction to the Casimir energy density and generation of topological mass for both massless and massive real scalar fields. It is assumed that the scalar field obeys a helix boundary condition. In addition, it is also considered a CPT-even aether-type violation of the Lorentz symmetry. In the absence of the Lorentz violation we obtain analytical expressions for the loop correction to the Casimir energy density and to the mass of the scalar field. The same expressions are also obtained assuming the Lorentz violation in each of the spacetime directions. We also show some graphs that exhibit how the loop correction and the Lorentz violation affect the the Casimir energy density and the mass of the scalar field.

description: Current noisy intermediate-scale quantum devices suffer from various sources of intrinsic quantum noise. Overcoming the effects of noise is a major challenge, for which different error mitigation and error correction techniques have been proposed. In this paper, we conduct a first study of the performance of quantum Generative Adversarial Networks (qGANs) in the presence of different types of quantum noise, focusing on a simplified use case in high-energy physics. In particular, we explore the effects of readout and two-qubit gate errors on the qGAN training process. Simulating a noisy quantum device classically with IBM's Qiskit framework, we examine the threshold of error rates up to which a reliable training is possible. In addition, we investigate the importance of various hyperparameters for the training process in the presence of different error rates, and we explore the impact of readout error mitigation on the results.

Where Lexical Semantics Meets Spatial Description: A Framework for 'Klettern' and 'Steigen'
Creators: name: Weisgerber, Matthias
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: When representing motion linguistically, more information is hidden in the interaction of verb, subject, object and directional PP than current linguistic theories normally use. In order to capture this information interplay lexical verb entries must look deeper into the situation, using a formalization of conceptual knowledge – the information gained can be used to make lexical entries of verbs more simple and more efficient. After a case study of German steigen and klettern (both: climb) we want to propose a toolkit to model both semantic and conceptual knowledge and their interaction, thereby proposing a three-level framework. As a result, we will present both lexical entries and conceptual knowledge modules of the associated parts of information, to the effect that lexical entries can be kept less complex than suggested in previous theories.

description: We report the complex dielectric function of high-quality $A\textrm{Fe}_2\textrm{As}_2$, ($A$=Ca, Sr, Ba) single crystals with $T_{\mathrm{N}}\approx150\ \textrm{K}$, $200\ \textrm{K}$, and $138\ \textrm{K}$, respectively, determined by broadband spectroscopic ellipsometry at temperatures $10\leq T\leq300\ \textrm{K}$ and wavenumbers from $100\ \textrm{cm}^{-1}$ to $52000\ \textrm{cm}^{-1}$. In $\textrm{CaFe}_2\textrm{As}_2$ we identify the optical spin-density--wave gap $2Δ_{\mathrm{SDW}}\approx1250\ \textrm{cm}^{-1}$. The $2Δ_{\mathrm{SDW}}/(k_{\mathrm{B}}T_{\mathrm{N}})$ ratio, characterizing the strength of the electron-electron coupling in the spin-density--wave state, amounts to $\approx12$ in $\textrm{CaFe}_2\textrm{As}_2$, significantly larger than the corresponding values for the $\textrm{SrFe}_2\textrm{As}_2$ and $\textrm{BaFe}_2\textrm{As}_2$ compounds: 8.7 and 5.3, respectively. We further show that, similarly to the Ba-based compound, two characteristic SDW energy gaps can be identified in the infrared-conductivity spectra of both $\textrm{SrFe}_2\textrm{As}_2$ and $\textrm{CaFe}_2\textrm{As}_2$ and investigate their detailed temperature dependence in all three materials. This analysis reveals the existence of an anomaly in $\textrm{CaFe}_2\textrm{As}_2$ at a temperature $T^*\approx80\ \textrm{K}$, well below the Néel temperature of this compound, which implies weak coupling between the two SDW subsystems. The coupling between the two subsystems evolves to intermediate in the Sr-based and strong in the Ba-based material. The temperature dependence of the infrared phonons reveals clear anomalies at the corresponding Néel temperatures of the investigated compounds. In $\textrm{CaFe}_2\textrm{As}_2$, the phonons exhibit signatures of SDW fluctuations above $T_N$ and some evidence for anomalies at $T^*$. (full abstract in PDF)
