One-dimensional multicomponent fermions with delta function interaction in strong and weak coupling limits: Two-component Fermi gas

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: The Fredholm equations for one-dimensional two-component Fermions with repulsive and with attractive delta-function interactions are solved by an asymptotic expansion for A) strong repulsion, B) weak repulsion, C) weak attraction and D) strong attraction. Consequently, we obtain the first few terms of the expansion of ground state energy for the Fermi gas with polarization for these regimes. We also prove that the two sets of the Fredhom equations for weakly repulsive and attractive interactions are identical as long as the integration boundaries match each other between the two sides. Thus the asymptotic expansions of the energies of the repulsive and attractive Fermions are identical to all orders in this region. The identity of the asymptotic expansions may not mean that the energy analytically connects.

description: We examine the existence and stability of discrete spatial solitons in coupled nonlinear lasing cavities (waveguide resonators), addressing the case of active defocusing media, where the gain exceeds damping in the low-amplitude limit. A new family of stable localized structures is found: these are bright and grey cavity solitons representing the connections between homogeneous and inhomogeneous states. Solitons of this type can be controlled by the discrete diffraction and are stable when the bistability of homogenous states is absent.

description: What role do representations of the First World War play in media that reach a wide audience beyond the circle of experts? The following contribution focuses on this important question. Given the wealth of popular media throughout the world from 1914-1918 to the present, it is not intended to be exhaustive, merely illustrative. The selected examples are used to demonstrate how the memories of the war were shaped and changed by the various media that enjoy a large audience. Emphasis will be placed on Western Europe, where those sites of memory are located that also continue to have the greatest influence on the memory of the First World War and preserve it through the musealization of former battlefields. Comprehensive overviews of several popular media in the countries treated here (and beyond) - especially in reference to literature, films, and art - can be found elsewhere in 1914-1918-online.

Chemoenzymatic and fully stereocontrolled total syntheses of the antibacterial natural product (-)-platencin and an analogue
Creators: name: Chang, Ee Ling
Publisher: name: The Australian National University
Year: 2015

description: The rise of antibiotic-resistant bacteria represents a growing crisis that threatens global security and the world economy. The natural product platencin has recently been identified as a potent antibacterial agent with a novel mode of action. As such, it is an important lead in the development of next-generation antibacterials that are urgently needed because of the rapidly developing resistance to current therapies. The work detailed in this thesis exploits previous research carried out within the Banwell laboratories that led to complete the total syntheses of platencin and an analogue. The antibacterial properties of the analogue are also reported.

description: The first experimental evidence for direct CP violation in charm-quark decays has recently been presented by the LHCb collaboration in the difference between the D -> K+ K- and D -> pi+ pi- time-integrated CP asymmetries. We estimate the size of the effects that can be expected within the Standard Model and find that at leading order in 1/mc they are an order of magnitude smaller. However, tree-level annihilation type amplitudes are known to be large experimentally. This implies that certain formally 1/mc-suppressed penguin amplitudes could plausibly account for the LHCb measurement. Simultaneously, the flavor-breaking parts of these amplitudes could explain the large difference between the D -> K+ K- and D -> pi+ pi- decay rates.

Upon dilution, the pure model's first-order transition becomes of the second-order at a tricritical point. We compute accurately the critical exponents at the tricritical point. As expected from the Cardy-Jacobsen conjecture, they are compatible with their Random Field Ising Model counterpart. The conclusion is further reinforced by comparison with older data for the Potts model with four states.

Critical celebrations : metatheatre in Australian drama of the late twentieth and early twenty-first Centuries
Creators: name: Clode, Rebecca Louise
Publisher: name: The Australian National University
Year: 2015

description: This thesis is a study of the importance of metatheatrical strategies in Australian drama from 1979 to the present. While some attention has been paid previously to the use of metatheatrical techniques, in the work of individual playwrights such as Louis Nowra for example, there has been no study which foregrounds metatheatre as a distinctive dimension of Australian playwriting and playmaking in the last forty years. Applying arguments about metatheatre by scholars such as Hornby, Fisher and Greiner, Feldman and Boireau, the thesis argues for the importance of a distinctively Australian metatheatre that is multivalent in its capacity to illuminate the wider social, cultural and artistic contexts in which Australian drama has been produced. Adapting Hornby's arguments about the value of considering metatheatre holistically, the study deploys a range of critical approaches, combining textual and production analysis, archival research, interviews and reflections gained from the researcher's presence at rehearsals and as an audience member/participant in productions. Using these techniques, the study analyses four plays and their Australian productions, identifying them as vital to Australian metatheatre. These include: Dorothy Hewett's The Man from Mukinupin (1979), Louis Nowra's hitherto unexamined Royal Show (1982), Timberlake Wertenbaker's Our Country's Good (1988) and a recent metatheatrical work, Peta Murray's epic celebration of women's theatre, Things That Fall Over: an (anti-)musical of a novel inside a reading of a play, with footnotes, and oratorio as coda (2014). Through these four detailed case studies, the thesis demonstrates the ways in which metatheatre has been used to generate powerful elements of critique, particularly of Indigenous/non-Indigenous relations during times of national "celebration" such as the Bicentenary of 1988. It argues that metatheatre is a strategy for comment on the marginalisation of Indigenous people and on the position of women as creative writers, as well as a self-reflexive mechanism via which Australian theatre is able to celebrate its own (meta)theatrical heritage. Situating these canonical and lesser-known plays in relationship to each other and their respective production histories illuminates the particular effectiveness of metatheatre in Australian Drama in holding social and cultural critique in powerful tension with the affirmation of theatre as cause and vehicle for celebration.

description: A weighted automaton is functional if any two accepting runs on the same finite word have the same value. In this paper, we investigate functional weighted automata for four different measures: the sum, the mean, the discounted sum of weights along edges and the ratio between rewards and costs. On the positive side, we show that functionality is decidable for the four measures. Furthermore, the existential and universal threshold problems, the language inclusion problem and the equivalence problem are all decidable when the weighted automata are functional. On the negative side, we also study the quantitative extension of the realizability problem and show that it is undecidable for sum, mean and ratio. We finally show how to decide whether the language associated with a given functional automaton can be defined with a deterministic one, for sum, mean and discounted sum. The results on functionality and determinizability are expressed for the more general class of functional group automata. This allows one to formulate within the same framework new results related to discounted sum automata and known results on sum and mean automata. Ratio automata do not fit within this general scheme and different techniques are required to decide functionality.

description: We report on a theoretical study of the $K^- p \to ηΛ$ reaction near threshold by using an effective Lagrangian approach. The role of $s-$channel $Λ(1670)$, $t-$channel $K^*$ and $u-$channel proton pole diagrams are considered. We show that the total cross sections data are well reproduced. However, only including the $s-$wave $Λ(1670)$ state and the background contribution from $t-$ and $u-$channel are not enough to describe the bowl structures in the angular distribution of $K^- p \to ηΛ$ reaction, which indicates that there should be higher partial waves contributing to this reaction in some energy region. Indeed, if we considered the contributions from a $D_{03}$ resonance, we can describe the bowl structures, however, a rather small width ($\sim 2$ MeV) of this resonance is needed.

Labelled sequent calculi and automated reasoning for assertions in separation logic
Creators: name: Hou, Zhe
Publisher: name: The Australian National University
Year: 2015

description: Separation logic (SL) is an extension of Hoare logic to reason about programs with mutable data structures. This thesis studies automated reasoning for the assertional language (i.e., formulae that represent pre- and post-conditions) of separation logic. We start from the core of separation logic called Boolean BI (BBI), then consider various propositional abstract separation logics (PASLs) as extensions of BBI. These logics are "abstract" because they are independent of any particular concrete memory model. Finally, we look at separation logic with Reynolds's heap model semantics. We first try to capture BI logics using nested sequents, our design has a special structure of interleaving additive and multiplicative nested sequents. We discover that this nested structure causes much complication when considering the rules for transferring information between nested sequents. Then we change the angle to solve this problem by using labelled sequents. We present a labelled sequent calculus LS_BBI for BBI, the calculus is simple, sound, complete, and enjoys cut-elimination. We show that all the structural rules in LS_BBI can be localised around applications of certain logical rules, based on which we demonstrate a free variable calculus that deals with the structural rules lazily in a constraint system. We propose a heuristic method to quickly solve certain constraints, and show some experimental results to confirm that our approach is feasible for proof search. Based on LS_BBI, we develop a modular proof theory for various PASLs using cut-free labelled sequent calculi. We first extend LS BBI to handle Calcagno et al.'s original logic of separation algebras by adding rules for partial-determinism and cancellativity. We prove the completeness of our calculus via an intermediate calculus that enables us to construct counter-models from the failure to find a proof. We then capture other PASLs by adding rules for other properties in separation theory. We present a theorem prover based on our labelled calculi for these logics. For concrete heap semantics, we consider Reynolds's SL with all logical connectives but without arbitrary predicates. This logic is not recursively enumerable but is very useful in practice. We give a sound labelled sequent calculus LS_SL for this logic. We illustrate the subtle deficiencies of some existing proof calculi for SL, and show that our rules repair these problems. We extend LS SL with rules for linked lists and binary trees, giving a sound, complete and terminating proof system for a popular fragment called symbolic heaps. Our prover shows comparable results with Smallfoot on valid formulae and on formulae extracted from program verification examples, but it is not competitive on large invalid formulae. However, our prover handles the largest fragment of logical connectives in SL.
The role of karyopherin-alpha in the pathogenesis of TDP-43 proteinopathy
Creators: name: Armstrong, Bryson Walter
Publisher: name: University of British Columbia
Year: 2013

description: Aberrant cellular processing and targeting of TDP-43 has been implicated in a wide variety of neurological diseases such as frontotemporal lobar degeneration with ubiquitinated inclusions (FTLD-U) and amyotrophic lateral sclerosis (ALS). These diseases are characterized by the sequestration of TDP-43 into the cytoplasm of afflicted neurons, leading to the formation of ubiquitinated, cytoplasmic inclusions and an increased susceptibility to cellular insults. While the underlying causes of TDP-43 proteinopathy are unknown, we are investigating the role of a protein family known as the karyopherins in the nuclear targeting of TDP-43. Using co-immunoprecipitation in SH-SY5Y cells we determined that a major binding partner of TDP-43 is karyopherin-alpha 2 (KPNA2). Next, utilizing a high-density peptide array comprised of overlapping peptide sequences derived from TDP-43 we identified six regions where KPNA2 may directly interact with TDP-43. From these regions we developed six small, cell-penetrating peptides designed to specifically inhibit the interaction between KPNA2 and TDP-43. Through the use of these synthetic peptides, we were able to interfere with the binding of KPNA2 to TDP-43 in vitro. We found that the disruption of this specific protein-protein interaction was not sufficient to induce TDP-43 cytoplasmic sequestration, as determined by co-immunoprecipitation and subcellular fractionation assays. As our research focused primarily on healthy SH-SY5Y cells, future studies will focus on investigating the effects of peptide-mediated TDP-43 nuclear import impairment paired alongside oxidative insult. We will also investigate whether compensatory mechanisms within SH-SY5Y cells are responsible for the nuclear localization of TDP-43 in the absence of KPNA2-mediated nuclear import.

Understanding the behaviour of transition dairy cows
Creators: name: Proudfoot, Kathryn Louise
Publisher: name: University of British Columbia
Year: 2013

description: Many concerns over the welfare of dairy cattle occur during the time around parturition. As cows transition from a pregnant to a lactating state, they are at high risk of disease and other painful conditions. In most intensive housing systems, these ‘transition’ cows are also kept in environments designed for the ease of management, with little consideration given to the expression of natural behaviours. This thesis addresses two main themes that are currently missing from the transition cow literature: 1) using knowledge of behaviour to improve management and housing practices, and 2) using behaviour as an indicator of poor health. Chapters 3, 4 and 5 address the first theme, and provide evidence that common management practices that disturb cows during parturition may interfere with calving; cows moved from a group pen into an individual pen during a late stage of labour spent more time standing in the hour before calving and experienced prolonged stage II labour compared to those moved earlier. Next, two preference studies were used to determine the type of environments that cows prefer during parturition. Results suggest that cows prefer to be in an undisturbed, secluded environment during labour and calving. To address the second theme, Chapter 2 describes the growing evidence in the human and laboratory animal literature that social behaviour can be useful as both an indicator of illness, as well as an early predictor of disease. Yet, there is little research to date making this link in farm animals. The remaining chapters describe studies that used behaviour to identify cows with three major health problems: infectious disease, dystocia and lameness. Cows with infectious diseases ate less, spent more time lying and secluded themselves from a nearby group pen, all common sickness behaviours in other species. Feeding, social and standing behaviours were also found to predict cows at-risk for dystocia and lameness well before diagnosis. Collectively, these results provide evidence that a better understanding of transition cow behaviour can be useful to both improve housing and management, as well as identify cows at-risk for poor health.

description: We show that the rich structure of multipartite entanglement can be tested following a device-independent approach. Specifically we present Bell inequalities for distinguishing between different types of multipartite entanglement, without placing any assumptions on the measurement devices used in the protocol, in contrast with usual entanglement witnesses. We first address the case of three qubits and present Bell inequalities that can be violated by W states but not by GHZ states, and vice versa. Next, we devise 'sub-correlation Bell inequalities' for any number of parties, which can provably not be violated by a broad class of multipartite entangled states (generalizations of GHZ states), but for which violations can be obtained for W states. Our results give insight into the nonlocality of W states. The simplicity and robustness of our tests make them appealing for experiments.

description: The interaction between super-intense coherent x-ray light and nuclei is studied theoretically. One of the main difficulties with driving nuclear transitions arises from the very narrow nuclear excited state widths which limit the coupling between laser and nuclei. In the context of direct laser-nucleus interaction, we consider the nuclear width broadening that occurs when in solid targets, the excitation caused by a single photon is shared by a large number of nuclei, forming a collective excited state. Our results show that for certain isotopes, cooperative effects may lead to an enhancement of the nuclear excited state population by almost two orders of magnitude. Additionally, an update of previous estimates for nuclear excited state population and signal photons taking into account the experimental advances of the x-ray coherent light sources is given. The presented values are an improvement by orders of magnitude and are encouraging for the future prospects of nuclear quantum optics.

description: We study critical properties of the Kitaev-Heisenberg model on the honeycomb lattice at finite temperatures which might describe the physics of the quasi two-dimensional compounds, Na$_2$IrO$_3$ and Li$_2$IrO$_3$. The model undergoes two phase transitions as a function of temperature. At low temperature, thermal fluctuations induce magnetic long-range order by order-by-disorder mechanism. Magnetically ordered state with the spontaneously broken $Z_6$ symmetry persists up to a certain critical temperature. We find that there is an intermediate phase between the low-temperature ordered phase and the high-temperature disordered phase. The finite-sized scaling analysis suggests that the intermediate phase is a critical Kosterlitz-Thouless phase with continuously variable exponents. We argue that the intermediate phase has been actually observed above the low-temperature magnetically ordered phase in Na$_2$IrO$_3$, and likely in Li$_2$IrO$_3$.

Considerare i corpi minori come "asteroidi" o "comete" può essere riduttivo. Ce lo insegnano gli asteroidi Phaethon e Bennu, le cui attività non sono ancora comprese in tutti i loro aspetti. Per Phaethon però si è aperto uno spiraglio: l'attività di espulsione dei meteoroidi dalla sua superficie potrebbe essere dovuta alla sublimazione del sodio, come indicano sia il modello teorico, sia gli esperimenti di laboratorio condotti recentemente da un team del Jpl della Nasa

description: Quantum correlations are expected to respect all the conditions required for them to be good measures of quantumness in the bipartite scenario. In a multipartite setting, sharing entanglement between several parties is restricted by the monogamy of entanglement. We take over the concept of monogamy to an information-theoretic quantum correlation measure, and find that it violates monogamy in general. Using the notion of interaction information, we identify necessary and sufficient conditions for the measure to obey monogamy, for arbitrary pure and mixed quantum states. We show that while three-qubit generalized Greenberger-Horne-Zeilinger states follow monogamy, generalized W states do not.

description: In all empirical-network studies, the observed properties of economic networks are informative only if compared with a well-defined null model that can quantitatively predict the behavior of such properties in constrained graphs. However, predictions of the available null-model methods can be derived analytically only under assumptions (e.g., sparseness of the network) that are unrealistic for most economic networks like the World Trade Web (WTW). In this paper we study the evolution of the WTW using a recently-proposed family of null network models. The method allows to analytically obtain the expected value of any network statistic across the ensemble of networks that preserve on average some local properties, and are otherwise fully random. We compare expected and observed properties of the WTW in the period 1950-2000, when either the expected number of trade partners or total country trade is kept fixed and equal to observed quantities. We show that, in the binary WTW, node-degree sequences are sufficient to explain higher-order network properties such as disassortativity and clustering-degree correlation, especially in the last part of the sample. Conversely, in the weighted WTW, the observed sequence of total country imports and exports are not sufficient to predict higher-order patterns of the WTW. We discuss some important implications of these findings for international-trade models.

description: Since the introduction of the concept of human security in 1994, debates have raged regarding the definition and applicability of the concept. Proponents of human security have sought to define the concept so that it may be utilised, whereas critics of human security have argued that the concept is too broad and amorphous to be adopted or utilised by states in international relations. This thesis examines two states; Australia, which has never utilised the term, 'human security,' in its declaratory policies; and Canada, a state that, for a time, was one of the most vocal proponents of the concept in its foreign policy statements. The research examines the two countries' military interventions in Somalia (1992-1995 - prior to the introduction of human security as a concept) and Afghanistan (2001-2013 - after the concept's introduction) to establish if, and to what extent, human security featured in and/or shaped their missions. Drawing upon an analysis of Australia's and Canada's declaratory policies and implementation approaches for each mission, this thesis presents a unique analytical framework that assesses the degree of norm internalisation of human security by the two states. It argues that human security is both co-opted and adapted by states in military interventions when the limitation of traditional national security approaches is recognised and when such actions are in alignment with national values. This thesis finds that the core concept of human security can be, and has been, operationalised at the implementation level, regardless of whether the state has a clearly defined declaratory policy of human security or not. Further, states now perceive the core concept of human security as a necessary condition for mission success in military interventions; military security, alone, is no longer enough. The thesis concludes with the argument that, for states, the concept of human security works better in practice (implementation) than it does in theory (declaratory policies). Indeed, when it comes to incorporating the fundamental elements of human security in military interventions, this thesis argues, it is the practices of human security that drives, and helps create, policies based on human security.

description: Most recently, the measurement of the neutrino velocity with the OPERA detector in the CNGS beam shows unexpected indication, that the muon neutrino velocity, $v_ν$, exceeds the velocity of light in the vacuum, $c$, which is obviously in contradiction with the most basic hypothesis of modern physics. Within the framework of minimal Standard Model Extension, we discuss the modified dispersion relation and consequently the velocity-energy relation of muon neutrinos. The simplified models are fit to the OPERA data, Fermilab experiment and MINO data. We find that minimal Standard Extension can describe these long baseline superluminal neutrinos to a good accuracy. For the well-known tension between the OPERA measurement and the Supernova 1987A neutrino observation, we discussed two ways out of the contradiction.

description: The common spin Hamiltonians such as the Ising, XY, or Heisenberg model do not have ground states that are the graph states needed in measurement-based quantum computation. Various highly-entangled many-body states have been suggested as a universal resource for this type of computation, however, it is not easy to preserve these states in solid-state systems due to their short coherence times. Here we propose a scheme for generating a Hamiltonian that has a cluster state as ground state. Our approach employs a series of pulse sequences inspired by established NMR techniques and holds promise for applications in many areas of quantum information processing.

Entropy-related principles for non-equilibrium systems : theoretical foundations and applications to ecology and fluid dynamics
Creators: name: Bertram, Jason
Publisher: name: The Australian National University

description: The standard contemporary approaches to modelling non-equilibrium, many-body phenomena are to use detailed computational models or to analyse large datasets. Here we explore an alternative approach: the use of simple idealized models based on the novel application of statistical mechanics in a non-equilibrium, many-body setting. This thesis has two main elements. The first element is the development of idealized statistical mechanics models to address particular topics in physics and biology. The particular topics to be addressed are as follows: (i) we show using a statistical mechanics approach that global patterns of tree/grass co-existence in savanna ecology can be interpreted as primarily the result of the different water use of trees and grasses subject to considerable fluctuation due to other factors such as disturbances; (ii) we discuss the unification of stochastic and mechanistic approaches in community ecology using a statistical mechanics framework, and develop a statistical mechanical model of a plant ecosystem to predict species abundance patterns, stability-diversity relationships and a phase transition between vegetated and non-vegetated community states, aspects of ecosystem behaviour which have so far been studied largely in isolation from one another; (iii) we clarify aspects of Malkus's variational approach to anisotropic, inhomogeneous fluid turbulence and revisit his statistical stability argument for maximising flow quantities, discussing possible connections to statistical mechanical justifications for flow quantity maximisation. The second main element of this thesis is the discussion of some of the broader methodological concerns surrounding the use of statistical mechanics in a generalised non-equilibrium setting. A central theme of this discussion is emphasizing the distinction between statistical mechanics and statistical inference.

description: Contains the supplementary material for the paper "Detecting Developers' Task Switches and Types". All contents are explained in the file README.txt. Abstract: Developers' work on a broad variety of tasks during their days and constantly switch between tasks. While these task switches can be beneficial, they can also incur a high cognitive burden on developers, since they have to continuously remember and rebuild task context - the artifacts and applications relevant to the task. Researchers have therefore proposed to capture task context more explicitly and use this to provide better task support, such as task switch reduction or resumption support. Yet, these approaches generally require the developer to manually identify task switches. Automatic approaches for predicting task switches have so far been limited in their accuracy, scope and the time discrepancy between predicted and actual task switches.
 In our work, we examine the use of automatically collected computer interaction data for detecting developers' task switches as well as task types. In two field studies--a 4h observational study and a multi-day study with experience sampling--we collected data from a total of 25 professional developers. Our study results show that we are able to use temporal and semantic features from developers' computer interaction data to detect task switches and types in the field with high accuracy of 84% and 61% respectively, and within a short time window of less than 1.6 minutes on average from the actual task switch. We discuss our findings and their practical value for a wide range of applications in real work settings.
