Subjects: subject: Quantum Physics (quant-ph)

description: We consider position-dependent mass (PDM) Lagrangians/Hamiltonians in their standard textbook form, where the long-standing \emph{gain-loss balance} between the kinetic and potential energies is kept intact to allow conservation of total energy (i.e., $L=T-V$, $H=T+V$, and $dH/dt=dE/dt=0$). Under such standard settings, we discuss and report on $n$-dimensional PDM damped harmonic oscillators (DHO). We use some $n$-dimensional point canonical transformation to facilitate the linearizability of their $n$-PDM dynamical equations into some $n$-linear DHOs' dynamical equations for constant mass setting. Consequently, the well know exact solutions for the linear DHOs are mapped, with ease, onto the exact solutions for PDM DHOs. A set of one-dimensional and a set of $n$-dimensional PDM-DHO illustrative examples are reported along with their phase-space trajectories.

description: The Mg-Zn and Al-Zn binary alloys have been investigated theoretically under static isotropic pressure. The stable phases of these binaries on both initially hexagonal-close-packed (HCP) and face-centered-cubic (FCC) lattices have been determined by utilizing an iterative approach that uses a configurational cluster expansion method, Monte Carlo search algorithm, and density functional theory (DFT) calculations. Based on 64-atom models, it is shown that the most stable phases of the Mg-Zn binary alloy under ambient condition are $\rm MgZn_3$, $\rm Mg_{19}Zn_{45}$, $\rm MgZn$, and $\rm Mg_{34}Zn_{30}$ for the HCP, and $\rm MgZn_3$ and $\rm MgZn$ for the FCC lattice, whereas the Al-Zn binary is energetically unfavorable throughout the entire composition range for both the HCP and FCC lattices under all conditions. By applying an isotropic pressure in the HCP lattice, $\rm Mg_{19}Zn_{45}$ turns into an unstable phase at P$\approx$$10$~GPa, a new stable phase $\rm Mg_{3}Zn$ appears at P$\gtrsim$$20$~GPa, and $\rm Mg_{34}Zn_{30}$ becomes unstable for P$\gtrsim$$30$~GPa. For FCC lattice, the $\rm Mg_{3}Zn$ phase weakly touches the convex hull at P$\gtrsim$$20$~GPa while the other stable phases remain intact up to $\approx$$120$~GPa. Furthermore, making use of the obtained DFT results, bulk modulus has been computed for several compositions up to pressure values of the order of $\approx$$120$~GPa. The findings suggest that one can switch between $\rm Mg$-rich and $\rm Zn$-rich early-stage clusters simply by applying external pressure. $\rm Zn$-rich alloys and precipitates are more favorable in terms of stiffness and stability against external deformation.

description: The Temple of Olympian Zeus (or Olympeion) in Agrigento, Sicily was the largest Doric temple ever constructed, although it was never completed and now lies in ruins. It stands in the Valle dei Templi with a number of other major Greek temples. The Greek historian Polybius mentions it briefly in a 2nd century BC description of Akragas, commenting that „the temple of Olympian Zeus being unfinished but second it seems to none in Greece in design and dimensions.“ According to Diodorus, it remained unfinished due to the Carthaginian conquest of the city (405 BC). The temple was eventually toppled by earthquakes and in the 18th century was quarried extensively to provide building materials for the modern towns of Agrigento and nearby Porto Empedocle. Today it survives only as a broad stone platform heaped with tumbled pillars and blocks of stone.

description: We critically examine the question of scaling of the Deep Inelastic Scattering process in the medium Bjorken x region on a scalar boson in the framework of the AdS/QCD correspondence. To get the right polarization structure of the forward electroproduction amplitude, we show that one needs to add (at least) the scalar to scalar and scalar to vector hadronic amplitudes. This illustrates how the partonic picture may emerge from a simple scenario based on the AdS/QCD correspondence, provided one allows the conformal dimension of the hadronic field to equal 1 and use the concept of "hadron - parton duality" .

description: Shenvi, Kempe and Whaley's quantum random-walk search (SKW) algorithm [Phys. Rev. A 67, 052307 (2003)] is known to require $O(\sqrt N)$ number of oracle queries to find the marked element, where $N$ is the size of the search space. The overall time complexity of the SKW algorithm differs from the best achievable on a quantum computer only by a constant factor. We present improvements to the SKW algorithm which yield significant increase in success probability, and an improvement on query complexity such that the theoretical limit of a search algorithm succeeding with probability close to one is reached. We point out which improvement can be applied if there is more than one marked element to find.

The Upper Triassic Kutcho Formation Cassiar Mountains, north-central British-Columbia
Creators: name: Thorstad, Linda Elaine
Publisher: name: University of British Columbia
Year: 2010

description: The stratigraphic, lithologic, structural and chemical characteristics of the Kutcho Formation, an informally named Upper Triassic volcano-sedimentary rock sequence in the Cry Lake map area of north-central British Columbia, are presented and discussed in detail. The Kutcho Formation and overlying Upper Triassic Sinwa Limestone and Lower Jurassic Inklin Formation form the King Salmon assemblage which makes up a west vergent, fault-bounded allochthon whose basement is part of the ancient Pacific ocean floor represented by the Cache Creek Group. Major and trace element chemistry of the Kutcho volcanic rocks demonstrates that they are a calc-alkaline suite, formed within a volcanic island arc which was conterminous with the North American continent. The suite is distinctive in that it is composed mainly of a bimodal assemblage of basalt/basaltic andesite and rhyodacite/rhyolite. Unlike most ancient and present volcanic island arcs, andesitic rocks are rare. Chemically anomalous rocks (basic schist unit) display marked alkaline characteristics. Metasomatism, associated with deformation and remobi1ization of copper-zinc Kuroko-type volcanogenic massive sulphide deposits, may in part account for the alkaline nature of the basic schist. A Rb-Sr whole-rock isochron of 210 ± 10 Ma, with Sr87/Sr86 initial ratio of 0.7042, dates Kutcho volcanism as Upper Triassic. The King Salmon assemblage was isoclinally folded, metamorphosed, and thrust southwestward along the King Salmon fault in Toarcian to Middle Bajocian (Lower to pre-Middle Jurassic) time. Rocks developed a strong penetrative axial planar cleavage which is subparallel to the the sole of the King Salmon thrust. Metamorphic recrystallization at 300 to 450 degrees Centigrade produced greenschist facies mineral assemblages. The Kutcho Formation, and other coeval Triassic island arc sequences, were probably formed within an extensive island arc to the east of the Cache creek subduction complex. Positioning of Kutcho and related Takla, Stuhini, and Sitlika arc systems to the west of the Cache Creek subduction complex was accomplished by dextral, transcurrent motions in post Late Triassic time. The southwest vergence of faults bounding the King Salmon assemblage may have been the result of emplacement and underthrusting of the arc and related subduction sequences by the exotic terrane, known as Stikinia, in late Middle Jurassic time.

description: Large parts within the prehistoric landscape-complex „Stonehenge-Avebury“ are protected and the complex belongs to one of the earlier inscriptions on UNESCO´s World Heritage List. The prehistoric landscapes have been in the focus of historic research for more than 250 years; University of Bournemouth, National Trust, English Heritage (now Historic England) and the German Archaeological Institute (DAI) agreed upon a survey programme in 2007 to investigate the area between the monuments on both parts of the WHS. In Avebury the multi-channel-magnetometry has revealed deep insights into the landscape between the monuments. While some areas remain free from new indicators, other parts of the complex contain much more remains than previous surveys and research work have been able to detect, not only between the known monuments but also, as the example of Windmill Hill shows, within the historic complex. Cold-War intrusions disturbed parts of a barrow group and one of the “barrows” happens to be identified as base for a windmill. Remains from Roman, Saxon and mediaeval periods south of Waden Hill join up with the modern village of Avebury. In 2016 and 2017 surveys in the vicinity of the monuments will deliver sufficient data that are statistically relevant for further research.

description: [This paper was initially published in PHME conference in 2016, selected for further publication in International Journal of Prognostics and Health Management.] This paper describes an Autoregressive Partially-hidden Markov model (ARPHMM) for fault detection and prognostics of equipments based on sensors' data. It is a particular dynamic Bayesian network that allows to represent the dynamics of a system by means of a Hidden Markov Model (HMM) and an autoregressive (AR) process. The Markov chain assumes that the system is switching back and forth between internal states while the AR process ensures a temporal coherence on sensor measurements. A sound learning procedure of standard ARHMM based on maximum likelihood allows to iteratively estimate all parameters simultaneously. This paper suggests a modification of the learning procedure considering that one may have prior knowledge about the structure which becomes partially hidden. The integration of the prior is based on the Theory of Weighted Distributions which is compatible with the Expectation-Maximization algorithm in the sense that the convergence properties are still satisfied. We show how to apply this model to estimate the remaining useful life based on health indicators. The autoregressive parameters can indeed be used for prediction while the latent structure can be used to get information about the degradation level. The interest of the proposed method for prognostics and health assessment is demonstrated on CMAPSS datasets.

Here we present an action for the Maxwell-Lorentz without self interactions model, where each particle only responds to the fields of the other charged particles. The corresponding stress-energy tensor automatically conserves energy and momentum in Minkowski and other appropriate spacetimes.

description: The settlement structures of the Ladon Valley were explored as part of the project „Olympia and its environment“. The poleis at the Ladon, one of the largest tributaries of the Alpheios in the border region between Elis and Arcadia, with their pastoral economic patterns are closely connected to the supply of the Sanctuary of Zeus in Olympia. In particular, the following cities were investigated: Thaliades and Halous at the upper Ladon, which narrows to a deep gorge there, and Thelpousa at the lower Ladon, where the wider riverbed also allowed for agriculture without elaborate terracing.

description: Exact analytical diagonalization is used to study the bipartite entanglement of the antiferromagnetic mixed spin-(1/2,$S$) Heisenberg dimer (MSHD) with the help of negativity. Under the assumption of uniaxial single-ion anisotropy affecting higher spin-$S$ ($S\!>\!1/2$) entities only, the ground-state degeneracy $2S$ is partially lifted and the ground state is two-fold degenerate with the total magnetization per dimer $\pm(S\!-\!1/2)$. It is shown that the largest quantum entanglement is reached for the antiferromagnetic ground state of MSHD with arbitrary half-odd-integer spins $S$, regardless of the exchange and single-ion anisotropies. Contrary to this, the degree of a quantum entanglement in MSHD with an integer spin $S$ for the easy-plane single-ion anisotropy, exhibits an increasing tendency with an obvious spin-$S$ driven crossing point. It is shown that the increasing spin magnitude is a crucial driving mechanism for an enhancement of a threshold temperature above which the thermal entanglement vanishes. The easy-plane single-ion anisotropy together with an enlargement of the spin-$S$ magnitude is other significant driving mechanism for an enhancement of the thermal entanglement in MSHD.

description: A scaling relation of the anomalous Hall effect recently found in a ferromagnetic semiconductor (Ti,Co)O_2_ is compared with those of various ferromagnetic semiconductors and metals. Many of these compounds with relatively low conductivity sigma_xx_ < 10^4 ohm^-1 cm^-1 are also found to exhibit similar relation: anomalous Hall conductivity sigma_AH_ approximately scales as sigma_AH_ proportional to sigma_xx_^1.6, that is coincident with a recent theory. This relation is valid over five decades of sigma_xx_ irrespective of metallic or hopping conduction.

description: The settlement mound of Aruchlo in the Kvemo Kartli southwest of Tblisi was built up during 5800 and 5400 BC and represents the Earliest Neolithic in the Southern Caucasus region. Thanks to the “Kura in Motion” programme of DFG and ANR Aruchlo could be studied in a wider framework of Neolithic settlements in the Kura valley (Menteshtepe) and the Mil steppe. The excavation in Aruchlo documented for the first time a considerable number of large ditches which were dug into the settlement mound from different occupation layers and which were refilled in a structured way. Similar phenomena could be observed in the Mil steppe. The ditches had no practical function but can be considered as “ritual” in a broad sense. In the light of these discoveries the interpretation of the mound must be revised.

description: The oppidum of Manching, Lkr. Pfaffenhofen/Ilm, has been the only longterm project of the Romano-Germanic Commission at Frankfurt/Main since 1955/56. During this time, a large area of 30 ha has been excavated (Abb. 1) which has yielded valuable information on Celtic urbanization and society. With 380 ha of unevenly settled interior, surrounded by a massive wall, Manching is one of the largest oppida in Europe. The earliest traces of later Iron Age occupation belong to the late 4th century, the latest belong to the mid- 1st century BC. During the last years two PhD theses could present new results, one of them concerning the environment of Manching, the other analyzing the function of the southern periphery of the oppidum and the role of ditch systems.

description: We investigate the equidistribution of the eigenfunctions on quantum graphs in the high-energy limit. Our main result is an estimate of the deviations from equidistribution for large well-connected graphs. We use an exact field-theoretic expression in terms of a variant of the supersymmetric nonlinear sigma-model. Our estimate is based on a saddle-point analysis of this expression and leads to a criterion for when equidistribution emerges asymptotically in the limit of large graphs. Our theory predicts a rate of convergence that is a significant refinement of previous estimates, long-assumed to be valid for quantum chaotic systems, agreeing with them in some situations but not all. We discuss specific examples for which the theory is tested numerically.

Follow-up of non-transiting planets detected by Kepler. Confirmation of three hot-Jupiters and validation of three other planets

description: The direct detection of new extrasolar planets from high-precision photometry data is commonly based on the observation of the transit signal of the planet as it passes in front of its star. Close-in planets, however, leave additional imprints in the light curve even if they do not transit. These are the so-called phase curve variations that include ellipsoidal, reflection and beaming effects. In Millholland & Laughlin (2017), the authors scrutinized the Kepler database looking for these phase variations from non-transiting planets. They found 60 candidates whose signals were compatible with planetary companions. In this paper, we perform a ground-based follow-up of a sub-sample of these systems with the aim of confirming and characterizing these planets and thus validating the detection technique. We used the CAFE and HERMES instruments to monitor the radial velocity of ten non-transiting planet candidates along their orbits. We additionally used AstraLux to obtain high-resolution images of some of these candidates to discard blended binaries that contaminate the Kepler light curves by mimicking planetary signals. Among the ten systems, we confirm three new hot-Jupiters (KIC8121913 b, KIC10068024 b, and KIC5479689 b) with masses in the range 0.5-2 M$_{\rm Jup}$ and set mass constraints within the planetary regime for the other three candidates (KIC8026887b, KIC5878307 b, and KIC11362225 b), thus strongly suggestive of their planetary nature. For the first time, we validate the technique of detecting non-transiting planets via their phase curve variations. We present the new planetary systems and their properties. We find good agreement between the RV-derived masses and the photometric masses in all cases except KIC8121913 b, which shows a significantly lower mass derived from the ellipsoidal modulations than from beaming and radial velocity data.

Carapace broader than long, carapace oval, moderately convex (Fig. 2A); dorsal surface smooth, regions moderately defined; hepatic region more or less granulated; mesogastric region limited by shallow transverse portion of cervical groove; front bilobed with deep notch, each lobe more or less convex; frontal and epigastric regions with rows of setae; anterolateral margins with three stout triangular teeth, nearly in equal size, first anterolateral teeth absolutely separated from the exorbital angle (Fig. 2A); distinct lobe between frontal lobe and inner orbital angle, supraorbital region with two faint fissures, outer orbital angle without tooth (Fig.2A). Third maxillipeds completely covering buccal cavern when closed; ischium rectangular; merus quadrate, about 1.2 times as long as broad; merus and ischium with some small granules and setae (Fig. 2E); palp (carpus, propodus and dactylus) short, stout (Fig. 2E); exopod stout, inner margin moderately denticulate, with setae.

Ambulatory legs with anterior margins sparsely lined with soft setae (Fig. 2G).
Remarks. De Man (1902) initially described Heteropanope africanus from the Ivory Coast. Further studies and comparisons between Heteropanope and Pilumnopeus showed that this species really belongs to the genus Pilumnopeus (Davie 1989). Manning & Holthuis (1981) pointed out that Pilumnopeus africanus is restricted to West Africa (Guinea to Cameroon), where it occupies estuaries and lagoons. This is the first record of Pilumnopeus africanus from the Persian Gulf, and the first record well outside of its normal distribution.
Distribution. Northwestern Indian Ocean: Persian Gulf, West Africa.

description: We consider the theoretical description of real-time counting of electrons tunneling through a Coulomb-blockade quantum dot using a detector with finite bandwidth. By tracing out the quantum dot we find that the dynamics of the detector effectively is non-Markovian. We calculate the cumulant generating function corresponding to the resulting non-Markovian rate equation and find that the measured current cumulants behave significantly differently compared to those of a Markovian transport process. Our findings provide a novel interpretation of noise suppression found in a number of systems.

description: Кекса ва қари  ёш - инсон ҳаётининг муҳим даврларидан бири бўлиб, бу даврда организмда морфологик ва функционал ўзгаришлар рўй беради. Хусусан ёш ўтиши билан жисмоний фаолликнинг камайиши одамларда ортиқча тана вазнининг пайдо бўлишига сабаб бўлади. Тана вазнинг ортиши организмда ёғ тўқимасининг йиғилиши ҳисобига вужудга келади. Ёғлар  асосан қорин ва бел соҳаларида йиғилиши сабабли одамларда абдоминал семизлик юзага келади. Абдоминал семизликнинг мавжудлиги прогностик жиҳатдан ёмон бўлиб, ҳаёт учун хавф солувчи оғир касалликларга олиб келади.

description: The area of the Temple of Heliopolis in Matariya was enclosed by two parallel courses of mud brick walls of different date, measuring about 1100 m east-west and 900 m north-south. Approximately 100 m of this outer enclosure wall are rather well preserved to a height of 3 m. The architectural survey finished the documentation of 60 m and pursued a section on top of the outer enclosure wall to investigate the junction of two segments. Built in alternate panels of concave and convex courses of mud brick, the structural analysis of the walls allows to assume, that the stability could be increased in conditions of permanent weight. Based on these observations it can be concluded that this construction technique brought essential structural benefits.

description: The appearance of the Nile riverbanks north of Aswan is the result of a long evolution in which geological, climatological, geomorphological and anthropic factors played a role. In order to disentangle this evolution, a surface survey and shallow drillings were conducted on the eastern shore of the Nile, precisely in the area of the villages Abu el-Rish Qibli, Abu el-Rish Bahari and the former island Geziret Bahrif. Results show amongst others a continuous and up to 3 m thick occupation layer of the Roman and Medieval Period which is covered by more recent accumulations of Nile mud.
Thermal maturation of the Western Canadian Sedimentary Basin in the Rocky Mountain foothills and plains of Alberta south of the Red Deer River

description: Vitrinite reflectance was measured for over 600 samples of coal and coaly particles from Jurassic to Paleocene strata in the Foreland Basin of southern Alberta, south of the Red Deer River, to establish a regional base of maturity data for modeling thermal history. The relationship between random and maximum reflectance for coals in the study area is: %RoR = 0.938 x %RoMax + .00112. Maturity of coal in strata of the same age generally increases from east to west across the Plains; however, significant variation in maturity is apparent in the Plains, possibly as a result of varying geothermal gradients. Maturity increases from south to north in the Disturbed Belt in the study area. Coalification gradients in the axis of the Basin are exceedingly low, averaging 0.07 log %RoR/km, a manifestation of very low paleogeothermal gradients resulting from rapid sediment deposition in the Paleogene. Time-averaged paleo-geothermal gradients for the deepest part of the Basin range from 7.5 to 15 deg. C./km based on measured coalification gradients. The thickness of eroded Tertiary section in the axis of the Basin is estimated to range from 5 to 9 km with an average value of about 6 to 7 km. Time-temperature modeling using an integral form of the Lopatin equation shows that for most of the Jura-Cretaceous wedge, the level of maturity required for hydrocarbon generation was not attained until the late Eocene. Syn- to post-orogenic maturation of strata in the Plains is a result of Basin loading by overthrust sheets or molasse. In the Disturbed Belt, a significant component of maturation resulted from overthrusting, as evident from maturity profiles of deep wells. A model describing the effect of overthrusting on maturity of footwall strata shows that paleo-geothermal gradients in the Disturbed Belt have been low, less than 20 deg. C./km, since Jurassic, and that thrust sheet thickness was probably 5 km or less in the Waterton, Highwood River (Foothills), and Jumping Pound areas, and greater than 5 km in the Highwood River (Front Ranges), and Burnt Timber Creek areas.

description: Using the method of maximal cuts, we obtain a form of the three-loop four-point scattering amplitude of N=8 supergravity in which all ultraviolet cancellations are made manifest. The Feynman loop integrals that appear have a graphical representation with only cubic vertices, and numerator factors that are quadratic in the loop momenta, rather than quartic as in the previous form. This quadratic behavior reflects cancellations beyond those required for finiteness, and matches the quadratic behavior of the three-loop four-point scattering amplitude in N=4 super-Yang-Mills theory. By direct integration we confirm that no additional cancellations remain in the N=8 supergravity amplitude, thus demonstrating that the critical dimension in which the first ultraviolet divergence occurs at three loops is D_c=6. We also give the values of the three-loop divergences in D=7,9,11. In addition, we present the explicitly color-dressed three-loop four-point amplitude of N=4 super-Yang-Mills theory.

description: Metal nanoparticles (MNs) are the center of attention in different branches of applied sciences as they have unique features in comparison with bulk ones. They are very effective, low cost and stable antibacterial agents which resisting them requires many mutations. Metal nanoparticles first anchor to the bacterial cell wall and interact with thiol and phosphorus groups of respiratory enzymes resulting in their inactivation. These nanostructures can penetrate into the cell via various mechanisms that distort cell integrity leading to cell content leakage followed with weakening of proton motive force functioning and inhibition of ATP synthesis. After penetration, MNs implement denaturation in DNA and RNA molecular structures hinder cellular replication, transcription and translation mechanisms. Metal nanoparticles induce ROS generation which has a detrimental effect on cell viability. Beside, sum of these effects and mechanisms may lead to inhibition of bacterial cell division, cell disruption and the decline of bacterial populations.

description: The Corpus of Ancient Sarcophagus reliefs is a long-term business of the German Archaeological Institute. Its history dates back to the 19th century. The Repertorium der christlich-antiken Sarkophage founded by Friedrich- Wilhelm Deichmann is however younger; the first volume had been published by the German Archaeological Institute in 1967. The following report describes the digitization of photographs of Roman and late antique sarcophagi in the ARACHNE database jointly operated by the University of Cologne and the German Archaeological Institute and the conclusion of the fifth and final volume of the Repertorium der christlich-antiken Sarkophage.

description: We consider the electronic properties of ferromagnetic bulk GaMnAs at zero temperature using two realistic tight-binding models, one due to Tang and Flatte and one due to Masek. In particular, we study the density of states, the Fermi energy, the inverse participation ratio, and the optical conductivity with varying impurity concentration x=0.01-0.15. The results are very sensitive to the assumptions made for the on-site and hopping matrix elements of the Mn impurities. For low concentrations, x<0.02, Masek's model shows only small deviations from the case of p-doped GaAs with increased number of holes while within Tang and Flatte's model an impurity-band forms. For higher concentrations x, Masek's model shows minor quantitative changes in the properties we studied while the results of the Tang and Flatte model exhibit qualitative changes including strong localization of eigenstates with energies close to the band edge. These differences between the two approaches are in particular visible in the optical conductivity, where Masek's model shows a Drude peak at zero frequency while no such peak is observed in Tang and Flatte's model. Interestingly, although the two models differ qualitatively the calculated effective optical masses of both models are similar within the range of 0.4-1.0 of the free electron mass.

description: The edicts and letters from Roman emperors, governors, and procurators preserved in inscriptions and on papyri form a important part of the documentary evidence used by classicists and jurists. The number of those documents is constantly increasing. Existing collections are outdated or only partial and unreliable. Given the diverse venues of publication and their distribution across the two disciplines of epigraphy and papyrology, it is extremely difficult for the individual scholar to get an overview. Therefore, under the direction of R. Haensch a comprehensive collection will be published over the next years, which will give access to those documents in their original form plus a translation and a detailed commentary. As first part a collection of edicts and letters from the praefecti Aegypti will be published.

description: Contrary to a paradigm of metal-enhanced fluorescence, unusually thick dielectric coatings can be very favorable to achieve extreme values of averaged fluorescence enhancement factor $\bar F\gtrsim 3000$ for emitters located on the surface, or in the interior, of the shell of Au@dielectric spherical core-shell particles under realistic conditions, even for the emitters with 100% intrinsic quantum yield. Thick dielectric coatings facilitate high-quality transverse electric (TE) multipole ($\ell=7$) resonances which are shown as the major cause for the reported extraordinary values of $\bar F$.

description: The AM Canum Venaticorum stars are rare interacting white dwarf binaries, whose formation and evolution are still poorly known. The Sloan Digital Sky Survey provides, for the first time, a sample of 6 AM CVn stars (out of a total population of 18) that is sufficiently homogeneous that we can start to study the population in some detail. We use the Sloan sample to `calibrate' theoretical population synthesis models for the space density of AM CVn stars. We consider optimistic and pessimistic models for different theoretical formation channels, which yield predictions for the local space density that are more than two orders of magnitude apart. When calibrated with the observations, all models give a local space density of 1-3x10^{-6} pc^{-3}, which is lower than expected. We discuss the implications for the formation of AM CVn stars, and conclude that at least one of the dominant formation channels (the double-degenerate channel) has to be suppressed relative to the optimistic models. In the framework of the current models this suggests that the mass transfer between white dwarfs usually cannot be stabilized. We furthermore discuss evolutionary effects that have so far not been considered in population synthesis models, but which could be of influence for the observed population. We finish by remarking that, with our lower space density, the expected number of Galactic AM CVn stars resolvable by gravitational-wave detectors like LISA should be lowered from current estimates, to about 1,000 for a mission duration of one year.
