description: The early post-merger phase of a binary neutron-star coalescence is shaped by characteristic rotational velocities as well as violent density oscillations and offers the possibility to constrain the properties of neutron star matter by observing the gravitational wave emission. One possibility to do so is the investigation of gravitational wave damping through the bulk viscosity which originates from violations of weak chemical equilibrium. Motivated by these prospects, we present a comprehensive report about the implementation of the self-consistent and second-order formulation of the equations of relativistic hydrodynamics for dissipative fluids proposed by Müller, Israel and Stewart. Furthermore, we report on the results of two test problems, namely the viscous damping of linear density oscillations of isolated nonrotating neutron stars and the viscous migration test, both of which confirm our implementation and can be used for future code tests. Finally, we present fully general-relativistic simulations of viscous binary neutron-star mergers. We explore the structural and thermal properties of binary neutron-star mergers with a constant bulk-viscosity prescription and investigate the impact of bulk viscosity on dynamical mass ejection. We find that inverse Reynolds numbers $\sim 1\%$ can be achieved for the highest employed viscosity thereby suppressing the dynamically ejected mass by a factor of $\sim 5$ compared to the inviscid case.

description: Its piezo- and potentially ferroelectric properties make the metastable kappa polymorph of Ga$_2$O$_3$ an interesting material for multiple applications, while In-incorporation into any polymorphs of Ga$_2$O$_3$ allows to lower their bandgap. In this work, we provide a guideline to achieve single phase $κ$-, $β$-Ga$_2$O$_3$ as well as their (In$_x$Ga$_{1-x}$)$_2$O$_3$ alloys up to x = 0.14 and x = 0.17 respectively, using In-mediated metal exchange catalysis in plasma assisted molecular beam epitaxy (MEXCAT-MBE). The polymorph transition from $κ$ to $β$ is also addressed, highlighting the fundamental role played by the thermal stability of the $κ$-Ga$_2$O$_3$. Additionally, we also demonstrate the possibility to grow ($\bar{2}$01) $β$-Ga$_2$O$_3$ on top of $α$-Al$_2$O$_3$ (0001) at temperatures at least 100 °C above those achievable with conventional non-catalyzed MBE, opening the road for increased crystal quality in heteroepitaxy. The role of the substrate, as well as strain and structural defects in the growth of $κ$-Ga$_2$O$_3$ is also investigated by growing simultaneously on three different materials: (i) $α$-Al$_2$O$_3$ (0001), (ii) 20 nm of ($\bar{2}$01) $β$-Ga$_2$O$_3$ on $α$-Al$_2$O$_3$ (0001) and (iii) ($\bar{2}$01) $β$-Ga$_2$O$_3$ single crystal.

description: Bilayer materials may support interlayer excitons comprised of electrons in one layer and holes in the other. In experiments, a non-zero exciton density is typically sustained by a bias chemical potential, implemented either by optical pumping or by electrical contacts connected to the two layers. We show that if charge can tunnel between the layers, the chemical potential bias means that an exciton condensate is in the dynamical regime of ac Josephson effect. It has physical consequences such as tunneling currents and the ability to tune a condensate from bright (emitting coherent photons) to dark by experimental controlling knobs. If the system is placed in an optical cavity, coupling with cavity photons favors different dynamical states depending on the bias, realizing superradiant phases.

description: Wearable devices that relocate tactile feedback from fingertips can enable users to interact with their physical world augmented by virtual effects. While studies have shown that relocating same-modality tactile stimuli can influence the one perceived at the fingertip, the interaction of cross-modal tactile stimuli remains unclear. Here, we investigate how thermal cues applied on the index finger's proximal phalanx affect vibrotactile sensitivity at the fingertip of the same finger when employed at varying contact pressures. We designed a novel wearable device that can deliver thermal stimuli at adjustable contact pressures on the proximal phalanx. Utilizing this device, we measured the detection thresholds of fifteen participants for 250 Hz sinusoidal vibration applied on the fingertip while concurrently applying constant cold and warm stimuli at high and low contact pressures to the proximal phalanx. Our results revealed no significant differences in detection thresholds across conditions. These preliminary findings suggest that applying constant thermal stimuli to other skin locations does not affect fingertip vibrotactile sensitivity, possibly due to perceptual adaptation. However, the influence of dynamic multisensory tactile stimuli remains an open question for future research.

description: In two-dimensional (2D) spin systems, the augmentation of spin fluctuations gives rise to quasi-long-range order; however, how they manifest in spin transport remains unclear. Here we investigate the spin Seebeck effect (SSE) in a quasi-2D antiferromagnet, BaNi$_2$V$_2$O$_8$, which has been reported to exhibit the Berezinskii-Kosterlitz-Thouless (BKT) transition owing to its distinct 2D nature. We found that the SSE in Pt / BaNi$_2$V$_2$O$_8$ persists well above the Néel temperature, significantly different from the behavior of 3D ordered magnets. Our numerical analysis for a 2D microscopic spin model supports the hypothesis that the observed SSE is linked to strong magnetic correlations in the BKT-like phase.

Magnetic impurities in an altermagnetic metal

Publisher: name: arXiv
Year: 2023
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We study the physics of dilute magnetic impurities in a two-dimensional altermagnetic metal. For the single impurity case, although the spin degeneracy is broken in an altermagnetic metal, we show that the antiferromagnetic Kondo coupling still flows to the strong coupling regime at low energies in terms of the one-loop renormalization-group equation. Moreover, the Kondo temperature may be enhanced or reduced, depending on the band structure and the electron density. To study the ground-state properties, we employ the variational wavefunction approach. We find that the impurity spin is completely screened at long distances, in contrast to the usual antiferromagnet. The $d$-wave nature of the spin-split Fermi surfaces in an altermagnetic metal is reflected in the correlation between the impurity and conduction electron spins, which exhibits the $C_{4z}$ symmetry of the altermagnet at long distances. The spin correlation decays as $1/r^3$ at long distances, and its amplitude oscillates with four different periods due to the interference between the spin splitting Fermi surfaces. Moreover, the values of these periods depend on the direction of observation. Similar phenomena also occur in the RKKY interaction in an AM metal.

description: Light-to-electricity conversion is crucial for energy harvesting and photodetection, requesting efficient electron-hole pair separation to prevent recombination. Traditional junction-based mechanisms using built-in electric fields fail in non-barrier regions. Homogeneous material harvesting under photovoltaic effect is appealing but only realized in non-centrosymmetric systems via bulk photovoltaic effect. Here we report the realization of photovoltaic effect by employing surface acoustic waves (SAW) to generate zero-bias photocurrent in a conventional layered semiconductor MoSe2. SAW induces periodic modulation to electronic bands and drags the photoexcited pairs toward the travelling direction. The photocurrent is extracted by a local barrier. The separation of generation and extraction processes suppresses recombination and yields large nonlocal photoresponse. We distinguish acousto-electric drag and electron-hole pair separation effect by fabricating devices of different configurations. The acousto-drag photovoltaic effect, enabled by piezoelectric integration, offers an efficient light-to-electricity conversion method, independent of semiconductor crystal symmetry.

description: Gravitational waves (GWs) from the inspiral of binary compact objects offer a one-step measurement of the luminosity distance to the event, which is essential for the measurement of the Hubble constant, $H_0$, which characterizes the expansion rate of the Universe. However, unlike binary neutron stars, the inspiral of binary black holes is not expected to be accompanied by electromagnetic radiation and a subsequent determination of its redshift. Consequently, independent redshift measurements of such GW events are necessary to measure $H_0$. In this study, we present a novel Bayesian approach to infer $H_0$ by measuring the overdensity of galaxies around individual binary black hole merger events in configuration space. We model the measured overdensity using the $3$D cross-correlation between galaxies and GW events, explicitly accounting for the GW event localization uncertainty. We demonstrate the efficacy of our method with $250$ simulated GW events distributed within $1$ Gpc in colored Gaussian noise of Advanced LIGO and Advanced Virgo detectors operating at O4 sensitivity. We show that such measurements can constrain the Hubble constant with a precision of $\lesssim 8 \%$ ($90\%$ highest density interval). We highlight the potential improvements that need to be accounted for in further studies before the method can be applied to real data.

The challenges of developing educational leadership in the Lao People's Democratic Republic
Creators: name: KITTIPHANH, DARAVONE
Publisher: name: RMIT University
Year: 2024

description: This research focuses on strengthening school leadership capacity in the Lao People’s Democratic Republic (Lao PDR) in the context of decentralization. The research will be significant for the Lao PDR Ministry of Education, and other educational ministries in developing countries, in their quest to develop leadership strategies at the local level. It will also inform bilateral and multilateral donors.

In the Lao educational context it is common for educational development projects to emphasise general management skills as one component of capacity building effort. This emphasis is reflected in the evaluation reports of these projects and more generally in the literature on educational development. However, the importance of leadership at the school and local level where most education policy is transformed into practice is hardly ever recognized. There is debate in the literature about the role of the school principal: manager, teacher or leaders of teaching and learning. This research project will contribute to this debate.

Management and leadership of education in the Lao PDR is characterised by complexity. This complexity emerges from the roles of donors, the changing development ideologies coupled with political developments within the country, poverty and tensions between the centre and the periphery. The complexity is exacerbated in poor districts that are remote from Vientiane. These forces are played out in a cultural milieu where hierarchy is prized and respected, at least officially.

This research project adopts a practitioner action research approach. This approach is consistent with the By Project mode of post-graduate research whose aims are not only to develop knowledge, but to improve the skills of the practitioner and to foster a change in practice. The methods include: interview and individual consultations, community consultations, a research journal, observations/field trips and textual analysis and strategies for sharing data with Lao practitioners. Like so many practitioner based research projects there is a fundamental role conflict - practitioner and researcher. Managing this conflict is paramount.

The research findings will be directly applicable to the management and development of the education sector in the Lao PDR, and will provide recommendations for improving both policy and practice. They will also help policy makers to understand the existing context of primary education management in the Lao PDR and provide important information about current approaches to primary education administration and management strategies. This will enable policy makers to make improvements in these areas. The best possible outcome would that this work might increase the effectiveness of administration and management systems as well as support the work of donors and contribute to more effective teaching and learning in the Lao PDR.

description: The growing demand for natural interactions with technology underscores the importance of achieving realistic touch sensations in digital environments. Realizing this goal highly depends on comprehensive databases of finger-surface interactions, which need further development. Here, we present SENS3 -- www.sens3.net -- an extensive open-access repository of multisensory data acquired from fifty surfaces when two participants explored them with their fingertips through static contact, pressing, tapping, and sliding. SENS3 encompasses high-fidelity visual, audio, and haptic information recorded during these interactions, including videos, sounds, contact forces, torques, positions, accelerations, skin temperature, heat flux, and surface photographs. Additionally, it incorporates thirteen participants' psychophysical sensation ratings (rough-smooth, flat-bumpy, sticky-slippery, hot-cold, regular-irregular, fine-coarse, hard-soft, and wet-dry) while exploring these surfaces freely. Designed with an open-ended framework, SENS3 has the potential to be expanded with additional textures and participants. We anticipate that SENS3 will be valuable for advancing multisensory texture rendering, user experience development, and touch sensing in robotics.

Investigation into reliability based methods to include risk of failure in life cycle cost analysis of reinforced concrete bridge rehabilitation
Creators: name: Zhu, Weiqi
Publisher: name: RMIT University
Year: 2024

description: Reliability based life cycle cost analysis is becoming an important consideration for decision-making in relation to bridge design, maintenance and rehabilitation. An optimal solution should ensure reliability during service life while minimizing the life cycle cost. Risk of failure is an important component in whole of life cycle cost for both new and existing structures.

Research work presented here aimed to develop a methodology for evaluation of the risk of failure of reinforced concrete bridges to assist in decision making on rehabilitation. Methodology proposed here combines fault tree analysis and probabilistic time-dependent reliability analysis to achieve qualitative and quantitative assessment of the risk of failure. Various uncertainties are considered including the degradation of resistance due to initiation of a particular distress mechanism, increasing load effects, changes in resistance as a result of rehabilitation, environmental variables, material properties and model errors. It was shown that the proposed methodology has the ability to provide users two alternative approaches for qualitative or quantitative assessment of the risk of failure depending on availability of detailed data. This work will assist the managers of bridge infrastructures in making decisions in relation to optimization of rehabilitation options for aging bridges.
The role of the pseudogap in cuprate superconductors revealed by the Hall effect

description: Cuprate high-temperature superconductors are known to have a normal-state pseudogap but, after many years of intense research, its relation to the superconductivity is still a mystery. Similarly, the in-plane Hall coefficient $R_{\rm H}$ has a large temperature variation caused by changes in the carrier density which is also a long-standing puzzle. We approach both problems by a kinetic theory of phase separation that reproduces the charge density wave by a free energy array of potential wells. The charge modulation favors local hole-hole attraction yielding local superconducting pairs and a transition by long-range phase order at $T_{\rm c}$. As the temperature increases the modulations decrease and the charge density increases by thermal activation. This approach reproduces the $R_{\rm H}$ of La$_{2-x}$Sr$_x$CuO$_4$ compounds of $x = 0.0 - 0.25$ and clarifies the role of the pseudogap and the disorder in cuprates.

The relationship between special educators in the DEECD Victorian Metropolitan Regions and Vietnamese parents of children with a disability
Creators: name: Le, Huong
Publisher: name: RMIT University
Year: 2024

description: The current thesis investigated the relationship between Vietnamese parents of children with a disability and special educators who worked with these parents in both mainstream and special schools in Melbourne Metropolitan Regions of the state of Victoria, Australia. The key objective of the study was to research the role of the parent-educator (interpersonal) relationship and its interrelatedness with the task: two major components of a home-school partnership. The research question that guided this study was 'How does the parent-educator relationship influence the operation of a family-centered home-school partnership?' With partnerships involving parents of diverse cultural backgrounds, investigating cultural influences on the partnership were an integral part of the research process. A qualitative interpretive approach was employed in searching for perceptions of involved pa rties about their home-school partnerships. The design selected was multiple embedded case studies with purposeful sampling. Influences on home-school partnership were investigated from a multidimensional perspective and were described and interpreted from the views of both parents and educators. The findings indicated that the relationship played a much more significant role than the task in the successfulness of an intercultural home-school partnership. Without a mutual understanding of home-school communication, the collaboration was far from productive or even did not work out. There was also evidence that a harmonious parent-educator interpersonal relationship did not seem to have any influence on the effectiveness of a home-school partnership without parent-educator mutual understanding and agreement in terms of goals and roles expectations. The need for the educators to be more appropriately equipped with cultural training and family-centered principles also arose from the study findings.

description: In this paper, we present a novel approach to the low rank matrix recovery (LRMR) problem by casting it as a group sparsity problem. Specifically, we propose a flexible group sparse regularizer (FLGSR) that can group any number of matrix columns as a unit, whereas existing methods group each column as a unit. We prove the equivalence between the matrix rank and the FLGSR under some mild conditions, and show that the LRMR problem with either of them has the same global minimizers. We also establish the equivalence between the relaxed and the penalty formulations of the LRMR problem with FLGSR. We then propose an inexact restarted augmented Lagrangian method, which solves each subproblem by an extrapolated linearized alternating minimization method. We analyze the convergence of our method. Remarkably, our method linearizes each group of the variable separately and uses the information of the previous groups to solve the current group within the same iteration step. This strategy enables our algorithm to achieve fast convergence and high performance, which are further improved by the restart technique. Finally, we conduct numerical experiments on both grayscale images and high altitude aerial images to confirm the superiority of the proposed FLGSR and algorithm.

Improved cross-language information retrieval via disambiguation and vocabulary discovery
Creators: name: Zhang, Ying
Publisher: name: RMIT University
Year: 2024

description: Cross-lingual information retrieval (CLIR) allows people to find documents irrespective of the language used in the query or document. This thesis is concerned with the development of techniques to improve the effectiveness of Chinese-English CLIR.

In Chinese-English CLIR, the accuracy of dictionary-based query translation is limited by two major factors: translation ambiguity and the presence of out-of-vocabulary (OOV) terms. We explore alternative methods for translation disambiguation, and demonstrate new techniques based on a Markov model and the use of web documents as a corpus to provide context for disambiguation. This simple disambiguation technique has proved to be extremely robust and successful. Queries that seek topical information typically contain OOV terms that may not be found in a translation dictionary, leading to inappropriate translations and consequent poor retrieval performance. Our novel OOV term translation method is based on the Chinese authorial practice of including unfamiliar English terms in both languages. It automatically extracts correct translations from the web and can be applied to both Chinese-English and English-Chinese CLIR. Our OOV translation technique does not rely on prior segmentation and is thus free from seg mentation error. It leads to a significant improvement in CLIR effectiveness and can also be used to improve Chinese segmentation accuracy.

Good quality translation resources, especially bilingual dictionaries, are valuable resources for effective CLIR. We developed a system to facilitate construction of a large-scale translation lexicon of Chinese-English OOV terms using the web. Experimental results show that this method is reliable and of practical use in query translation. In addition, parallel corpora provide a rich source of translation information. We have also developed a system that uses multiple features to identify parallel texts via a k-nearest-neighbour classifier, to automatically collect high quality parallel Chinese-English corpora from the web. These two automatic web mining systems are highly reliable and easy to deploy. In this research, we provided new ways to acquire linguistic resources using multilingual content on the web. These linguistic resources not only improve the efficiency and effectiveness of Chinese-English cross-language web retrieval; but also have wider applications than CLIR.
Between chaos and control: a practice-based investigation into the creative process of an improvised micro-budget screen production.
Creators: name: Berkeley, Leo
Publisher: name: RMIT University
Year: 2024

description: This PhD research has been conducted by project and, through the production of a 75 minute film called How To Change The World, has investigated screen production practice as research.

In that context, the research question used to frame the project is the following:  How can a creative practice in screen production be transformed into a research practice, which integrates professional, cultural and academic experience?

Using reflective practice as a methodology, the screen production project How To Change The World was developed to enable the consideration of this question, as well as building on themes and approaches explored in my prior filmmaking practice. I describe the film as a playful tapestry of stories exploring the world of a decaying neighbourhood pub. A significant feature of the project’s design was that it was a film made on a ‘micro’ budget. How To Change The World was also produced without a script and nearly all the dialogue was improvised. The film was designed to explore the significance of improvisation within the screen production process. This aspect of the research was initially focused on the performances of the actors but broadened in scope as its relevance to the central research question became more apparent.

 A significant focus of the research was on issues of identity and agency within the field of screen production. Within the broad framework of ideas proposed by Bourdieu in his work on the field of cultural production and drawing on related theorists such as Schön and cultural anthropologists Holland, Lachicotte, Skinner & Cain, I have argued that the screen production process for How To Change The World was a complex social, cultural and technical environment where I needed to negotiate multiple and often competing priorities in executing creative ideas, often under the pressure of time and resource constraints. The choices made in this improvisational environment were informed by both the history of my positions within the field, in both mainstream and marginal micro-budget sectors, as well as my dispositions to make certain types of films. These dispositions were, in turn, informed by a range of influences. I investigated the different ways that influences such as key films and prior production experiences can be seen to have an impact on the current creative production process. Like Schön’s ‘surfacing of tacit knowledge’, I investigated how my identity as a filmmaker informed the myriad creative and practical decisions made in the screen production process and whether a more explicit awareness of that identity enhanced my agency in the process, agency in this context being understood as the ability to act independently of the accepted and often internalised norms of the field.
Spin Seebeck Effect as a Probe for Majorana Fermions in Kitaev Spin Liquids

description: Quantum entanglement in strongly correlated electron systems often leads to exotic elementary excitations. Quantum spin liquids (QSLs) provide a paradigmatic example, where the elementary excitations are described by fractional quasiparticles such as spinons. However, such fractional quasiparticles behave differently from electrons, making their experimental identification challenging. Here, we theoretically investigate the spin Seebeck effect, which is a thermoelectric response via a spin current, as an efficient probe of the fractional quasiparticles in QSLs, focusing on the Kitaev honeycomb model. By comprehensive studies using the real-time dynamics, the perturbation theory, and the linear spin-wave theory based on the tunnel spin-current theory, we find that the spin current is induced by thermal gradient in the Kitaev spin liquid, via the low-energy fractional Majorana excitations. This underscores the ability of Majorana fermions to carry spin current, despite lacking spin angular momentum. Furthermore, we find that the induced spin current changes its sign depending on the sign of the Kitaev interaction, indicating that the Majorana fermions contribute to the spin current with (up-)down-spin like nature when the exchange coupling is (anti)ferromagnetic. Thus, in contrast to the negative spin current already found in a one-dimensional QSL, our finding reveals that the spin Seebeck effect can exhibit either positive or negative signals, contingent upon the nature of fractional excitations in the QSLs. We also clarify contrasting field-angle dependence between the Kitaev spin liquid in the low-field limit and the high-field ferromagnetic state, which is useful for the experimental identification. Our finding suggests that the spin Seebeck effect could be used not only to detect fractional quasiparticles emerging in QSLs but also to generate and control them.

Vulnerability analysis and fault location in power systems using complex network theory
Creators: name: Dwivedi, Ajendra
Publisher: name: RMIT University
Year: 2024

description: This thesis is dedicated to the study of Complex Network Theory with applications in power systems. The focus of the study is to analyze and solve power system problems by treating and modelling it as a network and applying the concepts from this theory. The work can be broadly classified into two parts: vulnerability analysis and fault location.

Two different centrality indices are proposed to analyze power system vulnerabilities. The first method utilizes shortest path betweenness approach and a centrality index is defined based on the power flow equation using reactance as the measure of portion of power flowing through any line. A few limitations of this method are improved in the second, where power system is considered to be capacitated and directed in any steady state and another centrality index based on the maximum flow algorithm is defined using admittance as weight to model the network. Based on Kirchhoff’s law, admittances are considered to be a measure of proportion and ease with which current or power flows through any line. Further, using maximum flow algorithm, lines are marked as important based on the fraction of total flow they carry between nodes. It is demonstrated by simulations on the IEEE 39 and IEEE 118 bus systems that failure of transmission lines identified as critical or vulnerable has a major impact on the efficiency and performance of the network, unlike the failure of random connections which have little or no effect.

In another study, cascading failures in power systems are assessed using line outage distribution factor and power transfer distribution factor together with Complex Network Theory. This work identifies the group of transmission lines which may be affected if any one line fails and investigates the sequence and depth to which the failure may propagate. Using the IEEE 14 bus system, it explains how the failure of one line can sometimes lead to a cascading failure and eventual blackout.

The next part of the research applies Complex Network Theory together with travelling wave based fault location techniques to locate faults in power systems. This study is further divided into two parts. The first part analyzes a power generation network, where the double-ended travelling wave theory is used to calculate the time stamp of fault transients at each node and then network topology of the system is used to first identify the faulty link and then calculate the fault distance. Finally, the single-ended travelling wave method is used to locate faults in power distribution systems. Due to the radial structure of transmission lines in such systems, more than one fault candidates may appear in the calculations, out of which only one is real. This ambiguity is resolved by taking advantage of the spanning tree like structure and using depth first search to identify the actual fault. The results reveal that the proposed methodologies are capable of locating single faults in power systems with reasonable accuracy.

description: This paper presents a machine learning-based method for the detection of the unique gravitational microlensing signatures of extended dark objects, such as boson stars, axion miniclusters and subhalos. We adapt MicroLIA, a machine learning-based package tailored to handle the challenges posed by low-cadence data in microlensing surveys. Using realistic observational timestamps, our models are trained on simulated light curves to distinguish between microlensing by point-like and extended lenses, as well as from other object classes which give a variable magnitude. We show that boson stars, examples of objects with a relatively flat mass distribution, can be confidently identified for $0.8 \lesssim r/r_E\lesssim 3$. Intriguingly, we also find that more sharply peaked structures, such as NFW-subhalos, can be distinctly recognized from point-lenses under regular observation cadence. Our findings significantly advance the potential of microlensing data in uncovering the elusive nature of extended dark objects. The code and dataset used are also provided.
