description: (Abridged) We use N-body simulations to study the effects that a divergent (i.e. "cuspy") dark matter (DM) profile introduces on the tidal evolution of dwarf spheroidal galaxies (dSphs). Our models assume cosmologically-motivated initial conditions where dSphs are DM-dominated systems on eccentric orbits about a host galaxy composed of a dark halo and a baryonic disc. We find that the resilience of dSphs to tidal stripping is extremely sensitive to the halo cuspiness; whereas dwarfs with a cored profile can be easily destroyed by the host disc, those with cusps always retain a bound remnant. For a given halo profile the evolution of the structural parameters as driven by tides is controlled solely by the total amount of mass lost. This information is used to construct a semi-analytic code that simulates the hierarchical build-up of spiral galaxies assuming different halo profiles and disc masses. We find that tidal encounters with discs tend to decrease the average mass of satellites at all galactocentric radii. Interestingly, satellites accreted before re-ionization (z>6), which may be singled out by anomalous metallicity patterns, survive only if haloes are cuspy. We show that the size-mass relation established from Milky Way (MW) dwarfs strongly supports the presence of cusps in the majority of these systems, as cored models systematically underestimate the masses of the known Ultra-Faint dSphs. Our models also indicate that a massive M31 disc may explain why many of its dSphs fall below the size-mass relationship derived from MW dSphs. We use our models to constrain the mass threshold below which star formation is suppressed in DM haloes, finding that luminous satellites must be accreted with masses above 10^8--10^9 M_sol in order to explain the size-mass relation observed in MW dwarfs.

description: A superpotential algebra is square if its quiver admits an embedding into a two-torus such that the image of its underlying graph is a square grid, possibly with diagonal edges in the unit squares; examples are provided by dimer models in physics. Such an embedding reveals much of the algebras representation theory through a device we introduce called an impression. Let A be a square superpotential algebra, Z its center, and \mathfrak{m} the maximal ideal at the origin of Spec(Z). Using an impression, we give a classification of all simple A-modules up to isomorphism, and give algebraic and homological characterizations of the simple A-modules of maximal k-dimension; show that Z is a 3-dimensional normal toric domain and Z_{\mathfrak{m}} is Gorenstein, by determining transcendence bases and Z-regular sequences; and show that A_{\mathfrak{m}} is a noncommutative crepant resolution of Z_{\mathfrak{m}}, and thus a local Calabi-Yau algebra. A particular class of square superpotential algebras, the Y^{p,q} algebras, is considered in detail. We show that the Azumaya and smooth loci of the centers coincide, and propose that each ramified maximal ideal sitting over the singular locus is the exceptional locus of a blowup shrunk to zero size.

Poetry and Tasmanian institutions of learning 1840-1950
Creators: name: Spaulding, Ralph
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examines the teaching of poetry in Tasmanian institutions of learning from 1840 to 1950. It identifies the poetry taught in government primary schools from 1840, the poetry prescribed for secondary public examinations from 1861, and that taught at the university from 1891. It examines the nature of this poetry and methods of its teaching and assessment, and considers changes that occurred in the pedagogical value and function of poetry during this period. The poetry taught in Tasmania's primary schools during the nineteenth century was included in school readers published in Britain and Ireland. This poetry reflected the religious and moral values of the British and Foreign School Society and the National Commissioners of Ireland, and the ideals of patriotism and imperialism promoted by the British government. The thesis demonstrates the extent to which these values and ideals influenced the selection of poetry, including Australian poetry, for school readers published specifically for Tasmanian primary schools in the first decades of the twentieth century. The poetry taught and examined at secondary and tertiary levels in Tasmania during the nineteenth century and early decades of the twentieth century conformed to British Public School and University syllabus requirements. The poems studied at these levels were from the classical English canon of poetry, and this canon remained largely unchanged until the 1940s when the University of Tasmania's Department of English initiated its pioneering course in Australian literature. By analysing courses of study, school inspection reports, and methods of teacher training, the thesis demonstrates that poetry in the primary school served initially as a means of teaching reading, speaking and recitation skills an, d of inculcating society's values and beliefs. Poetry was not studied as a form of literature to be appreciated and enjoyed until the early twentieth century. This change in the function of poetry challenged both the traditional canons of primary school poetry and the methods of its teaching. Similar developments occurred in senior secondary and university English studies. Initially, poetry was a useful source for the study of grammar, etymology and figurative language, before being valued and studied as a form of literature in its own right. The thesis considers the extent to which teachers were challenged by classroom methods designed to stimulate and measure students' personal and critical appreciation of poetry during the 1930s and 40s. It examines the tensions between the traditional moral and linguistic approaches to the teaching of poetry and the emerging application of Romantic ideologies that focussed on personal and creative responses to literature, and demonstrates that these tensions were not resolved within the timeframe of the study.

description: This paper investigates the thermodynamics of a large class of non-Hermitian, $PT$-symmetric oscillators, whose energy spectrum is entirely real. The spectrum is estimated by second-order WKB approximation, which turns out to be very accurate even for small quantum numbers, and used to generate the quantum partition function. Graphs showing the thermal behavior of the entropy and the specific heat, at all regimes of temperature, are given. To obtain the corresponding classical partition function it turns out to be necessary in general to integrate over a complex "phase space". For the wrong-sign quartic, whose equivalent Hermitian Hamiltonian is known exactly, it is demonstrated explicitly how this formulation arises, starting from the Hermitian case.

Danger: keep away! : moral panics and the banning of heavy metal music to protect young people
Creators: name: Shepherd, CM
Publisher: name: University Of Tasmania
Year: 2023

description: Since the late 1970s, heavy metal music has faced a considerable amount of negative media coverage. Much of this negative media coverage has been observed internationally, and has often lead to moral panics surrounding the music and its fans. These moral panics were often fuelled by concerned parent groups and the religious right, all of whom claimed that heavy metal music was a dangerous influence on young people because of the hidden Satanic messages that it supposedly contained. As a result of these panics, a number of heavy metal artists faced being banned or censored. But has Australia experienced a moral panic involving heavy metal? This research project uses discourse analysis to analyse Australian newspaper content to determine whether a moral panic surrounding heavy metal artists Slipknot and Marilyn Manson has occurred in Australia. While the international news coverage surrounding these two artists suggests that moral panics have occurred elsewhere, I argue that in Australia a classic moral panic has not occurred, but that some 'mild' and 'micro' panics surrounding these artists have occurred. However, these have not lead to any banning or censoring as a way of protecting young people. I argue that this lack of moral panic has come about because moral panic is now a standardised way of reporting within the media by journalists, and that the Australian news media now understand there is no need to create concern and panic regarding these heavy metal artist.
A Fashionable discourse: Oyster and the magazine reader

Publisher: name: University Of Tasmania

description: The world of magazines can range from serious publications such as Time or Australia's The Monthly, to the often trivialised work of New Idea, Woman's Day and Who Magazine. As a media text they are often disregarded as purely advertising, carriers for junk or soft journalism that doesn't offer very much more than entertainment or pleasure. It is easy to see why magazines are often disregarded as credible media texts. The saturation of celebrity discourse that has emerged over the past decade means that we no longer associate many publications with 'serious' issues such as politics, current affairs and international stories. On this basis society decides that magazines are not to be taken too seriously.

description: (Abridged) The ammonia method, which has been proposed to explore the electron-to-proton mass ratio, mu = m_e/m_p, is applied to nearby dark clouds in the Milky Way. This ratio, which is measured in different physical environments of high (terrestrial) and low (interstellar) densities of baryonic matter is supposed to vary in chameleon-like scalar field models, which predict strong dependence of both masses and coupling constant on the local matter density. High resolution spectral observations of molecular cores in lines of NH3 (J,K) = (1,1), HC3N J = 2-1, and N2H+ J = 1-0 were performed at three radio telescopes to measure the radial velocity offsets, DeltaV = V_rot - V_inv, between the inversion transition of NH3 (1,1) and the rotational transitions of other molecules with different sensitivities to the parameter dmm = (mu_obs - mu_lab)/mu_lab. The measured values of DeltaV exhibit a statistically significant velocity offset of 23 +/- 4_stat +/- 3_sys m/s. When interpreted in terms of the electron-to-proton mass ratio variation, this infers that dmm = (2.2 +/- 0.4_stat +/- 0.3_sys)x10^{-8}. If only a conservative upper bound is considered, then the maximum offset between ammonia and the other molecules is |DeltaV| <= 30 m/s. This gives the most accurate reference point at z = 0 for dmm: |dmm| <= 3x10^{-8}.

description: Tanulmányunk az értékelési részszempontokra adott súlyszámok hatásainak vizsgálatára épül a közbeszerzésben, amelynek folyamatát egy adott vállalat példáján keresztül mutatjuk be. A tanulmány jelentőségét az adja, hogy a közbeszerzési eljárásokban évente mintegy 3 600 milliárd forint értékű szerződéskötésre kerül sor. Ezekben az eljárásokban a nyertes ajánlattevő – akivel szerződéskötésre kerül sor – kiválasztását döntően befolyásolja az eljárásban alkalmazott értékelési módszer. Ezeket a befolyásoló tényezőket, hatásaikat mutatjuk be, hogy a cikk és a digitális modellezés alapján útmutatást adjunk a célszerű alkalmazásra. Az értékelésben elsőként a pontkiosztási módszert taglaljuk. A pontkiosztási módszer alapján a beérkezett ajánlatok értékelési részszempontjaihoz pontszámokat kell hozzárendelni, és a pontozási módszer révén kerül meghatározásra az egyes ajánlatok összpontszáma. A legmagasabb összpontszámú érvényes ajánlat a nyertes. A pontkiosztás módszere az egyik alapja a digitális modellnek, ezért ezzel részletesen foglalkozunk a tanulmányunkban. Az alkalmazáskor felmerülő problémákra konkrét esettekkel is rámutatunk, melyekkel a közbeszerzési eljárások előkészítésénél találkozni lehet. ---------------- Our study is based on an examination of the effects of weighting on valuation sub-criteria in public procurement, the process of which is illustrated through the example of a particular company. The significance of the study is the fact that in public procurement contracts about HUF 3,600 billion are awarded annually. In these procedures, the selection of the successful tenderer with whom the contract will be awarded is decisively influenced by the evaluation method used in the procedure. These influencing factors and their effects are presented to guide the application based on the article and digital modeling. The first point in the evaluation is the point allocation method. The scoring method shall assign points to the evaluation criteria of the offers received, and the scoring method shall determine the total score of each offer. The highest total valid bid is the winner. The point assignment method is one of the foundations of the digital model, so we will deal with it in detail in this study. The application problems are also highlighted in specific cases that may be encountered in the preparation of public procurement procedures.
Does socioeconomic status moderate the association between theory of planned behaviour variables and health promoting dietary behaviour? A systematic review and meta-analysis.
Creators: name: Figg, G
Publisher: name: University Of Tasmania
Year: 2023

description: Dietary behaviours are strongly patterned by socioeconomic status (SES). However, the role of SES in the self-regulation of health promoting dietary behaviour is not fully understood. This systematic review with meta-analysis investigated whether four individual-level measures of SES (income, occupation, education and race) moderate the relationships between Theory of Planned Behaviour (TPB) variables and health promoting dietary behaviour in adults. A systematic literature search identified 65 studies from 51 articles providing information on TPB variables, SES and health promoting dietary behaviour. Random-effects meta-analyses were conducted to generate pooled correlations corrected for sampling and measurement error. Results showed that all TPB variables were significantly associated with health promoting dietary behaviour, with intention having the strongest correlation with behaviour (21% of variance explained), followed by perceived behavioural control (PBC) (11%) attitude (7%) and subjective norm (2%). Random-effects meta-regression was used to investigate the moderating effects of individual-level measures of SES on these correlations. Results showed that none of the SES indicators were significant moderators of the relationship between TPB variables and health promoting dietary behaviour. These results suggest that associations between social-cognitive predictors and healthy dietary behaviour are not patterned by individual-level SES measures.

description: We propose new Lieb-Robinson bounds (bounds on the speed of propagation of information in quantum systems) with an explicit dependence on the interaction strengths of the Hamiltonian. For systems with more than two interactions it is found that the Lieb-Robinson speed is not always algebraic in the interaction strengths. We consider Hamiltonians with any finite number of bounded operators and also a certain class of unbounded operators. We obtain bounds and propagation speeds for quantum systems on lattices and also general graphs possessing a kind of homogeneity and isotropy. One area for which this formalism could be useful is the study of quantum phase transitions which occur when interactions strengths are varied.

In the time-like case we obtain generalisations of Kastor & Traschen's cosmological black holes: they have a specific time-dependence and the base-space must be 3-dimensional hyperCR/Gauduchon-Tod space. In the null-case, we find that the metric has a holonomy contained in Sim(2), give a general characterisation of the solutions, and give some examples. Finally, we point out that in some cases the solutions we found are non-BPS solutions to N=2 d=4 supergravity coupled to vector multiplets.

Under mild conditions, we prove that the preceding stochastic PDE has a unique solution that grows at most exponentially in time. And that, under natural conditions, it is "weakly intermittent." Along the way, we establish a comparison principle as well as a finite support property.

Studies of power quality : disturbance recognition
Creators: name: Ringrose, MJ
Publisher: name: University Of Tasmania
Year: 2023

description: Power quality is becoming increasingly important in power systems. The proliferation of modem power electronic devices has both decreased the quality of power on the electric grid and increased the equipment's sensitivity to power quality disturbances. In order to maintain an acceptable level of power quality in a power system, power quality monitoring devices have been designed. These devices are purchased by power utilities and customers in increasing numbers for the purpose of power quality trend logging and power quality disturbance capturing. Many power quality monitors will provide some information on the type of a power quality disturbance that has been recorded, however a reliable system for automatically classifying the full range of disturbance types is yet to be formalised. Recent advances in signal processing and artificial intelligence have put this goal within reach. A system for the automatic classification of recorded power quality disturbances is developed in this thesis. The system uses a variety of mathematical tools in order to produce an accurate and robust classification method. These tools include Fourier transforms, wavelet transforms, artificial neural networks, and fuzzy logic. Transient disturbances are analysed using the wavelet transform general modulus maxima technique and classified into their respective disturbance classes using a neuro-fuzzy pattern recognition scheme. The remaining disturbance types are analysed using Fourier transforms and classified into their respective disturbance classes using a simple decision making scheme. Also investigated in this thesis is a method for monitoring the harmonic output from nonlinear loads in a power system using a reduced number of harmonic monitoring stations. The method utilises a state estimation scheme with measurements from installed harmonic monitoring stations combined with pseudo-measurements provided by artificial neural networks.

description: We investigate a f(R) modification of gravity that is exponential in the Ricci scalar R to explain cosmic acceleration. The steepness of this dependence provides extra freedom to satisfy solar system and other curvature regime constraints. With a parameter to alleviate the usual fine tuning of having the modification strengthen near the present, the total number of parameters is only one more than LCDM. The resulting class of solutions asymptotes to w=-1 but has no cosmological constant. We calculate the dynamics in detail, examine the effect on the matter power spectrum, and provide a simple fitting form relating the two.

Loitering with intent: a cultural geography of Sullivans Cove

Publisher: name: University Of Tasmania
Year: 2023

description: This is a study that is drawn from the discipline of cultural geography. It explores the proposition that conviviality in public spaces contributes to a civil society, and seeks to identify the physical qualities and characteristics of a place that contribute to convivial activity. I have chosen to study conviviality in the spaces of Sullivans Cove on the waterfront of the capital city of Hobart, Tasmania, a landscape that in the last decade or more has undergone a transformation from a neglected working port to a centre of social and civic activity. I have adopted the character of a flineuse to take the reader through a journey of Sullivans Cove, and in so doing uncover real life activities that support the propositions that I have chosen to investigate. Flineuses are traditionally known as observers and loiterers of public spaces. The idea of the flineuse is used as a device in this study by which the urban landscape can be narrativised. Observing the public sphere with a flineuse raises questions about the aesthetic experiences of public spaces and the possibilities that these spaces hold for citizenship. This research revealed that conviviality has the potential to contribute to a civil society. For conviviality to prosper it requires a place that is both physically and psychologically safe, this is achieved through fulfilling conditions that encourage a diversity of people and activity into an area.rin

By means of analytical and numerical full-wave studies, we explore their image displacement/formation capabilities, and establish intriguing connections with configurations already known in the literature. Starting from these revisitations, we develop a number of nontrivial extensions, and illustrate their possible applications to the design of perfect radomes, anti-cloaking devices, and focusing devices based on double-positive (possibly nonmagnetic) media. These designs show that such anomalous features may be achieved without necessarily relying on negative-index or strongly resonant metamaterials, suggesting more practical venues for the realization of these devices.

description: Deep Learning (DL) methods have dramatically increased in popularity in recent years, with significant growth in their application to various supervised learning problems. However, the greater prevalence and complexity of missing data in such datasets present significant challenges for DL methods. Here, we provide a formal treatment of missing data in the context of deeply learned generalized linear models, a supervised DL architecture for regression and classification problems. We propose a new architecture, dlglm, that is one of the first to be able to flexibly account for both ignorable and non-ignorable patterns of missingness in input features and response at training time. We demonstrate through statistical simulation that our method outperforms existing approaches for supervised learning tasks in the presence of missing not at random (MNAR) missingness. We conclude with a case study of the Bank Marketing dataset from the UCI Machine Learning Repository, in which we predict whether clients subscribed to a product based on phone survey data.

Nonperturbative QCD Coupling and its $β$ function from Light-Front Holography

description: The light-front holographic mapping of classical gravity in AdS space, modified by a positive-sign dilaton background, leads to a nonperturbative effective coupling $α_s^{AdS}(Q^2)$. It agrees with hadron physics data extracted from different observables, such as the effective charge defined by the Bjorken sum rule, as well as with the predictions of models with built-in confinement and lattice simulations. It also displays a transition from perturbative to nonperturbative conformal regimes at a momentum scale $ \sim 1$ GeV. The resulting $β$ function appears to capture the essential characteristics of the full $β$ function of QCD, thus giving further support to the application of the gauge/gravity duality to the confining dynamics of strongly coupled QCD. Commensurate scale relations relate observables to each other without scheme or scale ambiguity. In this paper we extrapolate these relations to the nonperturbative domain, thus extending the range of predictions based on $α_s^{AdS}(Q^2)$.

HD271791: dynamical versus binary-supernova ejection scenario

description: The atmosphere of the extremely high-velocity (530-920 km/s) early B-type star HD271791 is enriched in $α$-process elements, which suggests that this star is a former secondary component of a massive tight binary system and that its surface was polluted by the nucleosynthetic products after the primary star exploded in a supernova. It was proposed that the (asymmetric) supernova explosion unbind the system and that the secondary star (HD271791) was released at its orbital velocity in the direction of Galactic rotation. In this Letter we show that to explain the Galactic rest-frame velocity of HD271791 within the framework of the binary-supernova scenario, the stellar remnant of the supernova explosion (a $\la$ 10 Msun black hole) should receive an unrealistically large kick velocity of $\geq$ 750-1200 km/s$. We therefore consider the binary-supernova scenario as highly unlikely and instead propose that HD271791 attained its peculiar velocity in the course of a strong dynamical three- or four-body encounter in the dense core of the parent star cluster. Our proposal implies that by the moment of encounter HD271791 was a member of a massive post-supernova binary.

description: Deep Learning (DL) methods have dramatically increased in popularity in recent years, with significant growth in their application to various supervised learning problems. However, the greater prevalence and complexity of missing data in such datasets present significant challenges for DL methods. Here, we provide a formal treatment of missing data in the context of deeply learned generalized linear models, a supervised DL architecture for regression and classification problems. We propose a new architecture, dlglm, that is one of the first to be able to flexibly account for both ignorable and non-ignorable patterns of missingness in input features and response at training time. We demonstrate through statistical simulation that our method outperforms existing approaches for supervised learning tasks in the presence of missing not at random (MNAR) missingness. We conclude with a case study of the Bank Marketing dataset from the UCI Machine Learning Repository, in which we predict whether clients subscribed to a product based on phone survey data.

description: A three-dimensional X-ray tomography is performed to investigate the internal structure and its evolution of a crumpled aluminum foil. The upper and lower bounds of the internal geometric fractal dimension are determined, which increase with the compression. Contrary to the simulation results, we find that the mass distribution changes from being inhomogeneous to uniform. Corroborated with the evidence from previous experiments, these findings support the physical picture that the elastic property precedes the plastic one at dominating the deformation and mechanical response for all crumpled structures. We show that the interior of a crumpled ball at the plastic regime can be mapped to the compact packing of a granular system.

description: A number of neutron star low-mass X-ray binaries have recently been discovered to show broad, asymmetric Fe K emission lines in their X-ray spectra. These lines are generally thought to be the most prominent part of a reflection spectrum, originating in the inner part of the accretion disk where strong relativistic effects can broaden emission lines. We present a comprehensive, systematic analysis of Suzaku and XMM-Newton spectra of 10 neutron star low-mass X-ray binaries, all of which display broad Fe K emission lines. Of the 10 sources, 4 are Z sources, 4 are atolls and 2 are accreting millisecond X-ray pulsars (also atolls). The Fe K lines are well fit by a relativistic line model for a Schwarzschild metric, and imply a narrow range of inner disk radii (6 - 15 GM/c^2) in most cases. This implies that the accretion disk extends close to the neutron star surface over a range of luminosities. Continuum modeling shows that for the majority of observations, a blackbody component (plausibly associated with the boundary layer) dominates the X-ray emission from 8 - 20 keV. Thus it appears likely that this spectral component produces the majority of the ionizing flux that illuminates the accretion disk. Therefore, we also fit the spectra with a blurred reflection model, wherein a blackbody component illuminates the disk. This model fits well in most cases, supporting the idea that the boundary layer is illuminating a geometrically thin disk.

Wave localization does not affect the breakdown of a Schrödinger-type amplifier driven by the square of a Gaussian field

description: We study the divergence of the solution to a Schrödinger-type amplifier driven by the square of a Gaussian noise in presence of a random potential. We follow the same approach as Mounaix, Collet, and Lebowitz (MCL) in terms of a distributional formulation of the amplified field and the use of the Paley-Wiener theorem [Commun. Math. Phys. {\bf 264}, 741-758 (2006) and {\bf 280}, 281-283 (2008)]. Our results show that the divergence is not affected by the random potential, in the sense that it occurs at exactly the same coupling constant as what was found by MCL without a potential. It follows {\it a fortiori} that the breakdown of the amplifier is not affected by the possible existence of a localized regime in the amplification free limit.

Recurrent Event Analysis in the Presence of Real-Time High Frequency Data via Random Subsampling

description: Digital monitoring studies collect real-time high frequency data via mobile sensors in the subjects’ natural environment. This data can be used to model the impact of changes in physiology on recurrent event outcomes such as smoking, drug use, alcohol use, or self-identified moments of suicide ideation. Likelihood calculations for the recurrent event analysis, however, become computationally prohibitive in this setting. Motivated by this, a random subsampling framework is proposed for computationally efficient, approximate likelihood-based estimation. A subsampling-unbiased estimator for the derivative of the cumulative hazard enters into an approximation of log-likelihood. The estimator has two sources of variation: the first due to the recurrent event model and the second due to subsampling. The latter can be reduced by increasing the sampling rate; however, this leads to increased computational costs. The approximate score equations are equivalent to logistic regression score equations, allowing for standard, “off-the-shelf” software to be used in fitting these models. Simulations demonstrate the method and efficiency-computation tradeoff. We end by illustrating our approach using data from a digital monitoring study of suicidal ideation. Supplementary materials for this article are available online.

description: We study the metal-insulator transition in a very general two-channel transport model, where charge carriers are coupled to a correlated background medium. The fluctuations of the background were described as bosonic excitations, having the ability to relax. Employing an analytical projector-based renormalization technique, we calculate the ground-state and spectral properties of this fermion-boson model and corroborate recent numerical results, which indicate---in dependence on the `stiffness' of the background medium---a Luttinger-liquid to charge-density-wave transition for the one-dimensional half-filled band case. In particular, we determine the renormalized electron and boson dispersion relations and show that the quantum phase transition is not triggered by a softening of the boson modes. Thus the charge density wave is different in nature from an usual Peierls distorted state.

description: Recently the supercooled Wahnstrom binary Lennard-Jones mixture was partially crystallized into ${\rm MgZn_2}$ phase crystals in lengthy Molecular Dynamics simulations. We present Molecular Dynamics simulations of a modified Kob-Andersen binary Lennard-Jones mixture that also crystallizes in lengthy simulations, here however by forming pure fcc crystals of the majority component. The two findings motivate this paper that gives a general thermodynamic and kinetic treatment of the stability of supercooled binary mixtures, emphasizing the importance of negative mixing enthalpy whenever present. The theory is used to estimate the crystallization time in a Kob-Andersen mixture from the crystallization time in a series of relared systems. At T=0.40 we estimate this time to be 5$\times 10^{7}$ time units ($\approx 1. ms$). A new binary Lennard-Jones mixture is proposed that is not prone to crystallization and faster to simulate than the two standard binary Lennard-Jones mixtures; this is obtained by removing the like-particle attractions by switching to Weeks-Chandler-Andersen type potentials, while maintaining the unlike-particle attraction.

description: We investigate a system of three tunnel-coupled semiconductor quantum dots in a triangular geometry, one of which is connected to a metallic lead, in the regime where each dot is essentially singly occupied. Both ferro- and antiferromagnetic spin-1/2 Kondo regimes, separated by a quantum phase transition, are shown to arise on tuning the interdot tunnel couplings and should be accessible experimentally. Even in the ferromagnetically-coupled local moment phase, the Kondo effect emerges in the vicinity of the transition at finite temperatures. Physical arguments and numerical renormalization group techniques are used to obtain a detailed understanding of the problem.
