description: Three dimensional wormholes are global solutions of Einstein-Hilbert action. These space-times which are quotients of a part of global AdS$_{3}$ have multiple asymptotic regions, each with conformal boundary $S^{1}\times\mathbb{R}$, and separated from each other by horizons. Each outer region is isometric to BTZ black hole, and behind the horizons, there is a complicated topology. The main virtue of these geometries is that they are dual to known CFT states. In this paper, we evaluate the full time dependence of holographic complexity for the simplest case of $ 2+1 $ dimensional Lorentzian wormhole spacetime, which has three asymptotic AdS boundaries, using the complexity equals volume (CV) conjecture. We conclude that the growth of complexity is non-linear and saturates at late times.

title: A DECISION SUPPORT MODEL FOR MOBILE TECHNOLOGY ENHANCED TEACHING

description: Acquiring new knowledge and key skills in an educational setting is important to develop and improve education quality by integrating technology with teaching and learning in the curriculum. The choice of technology will be the principal focus of innovative Mobile Learning Technology (MLT). Developing countries have difficulty in adopting technology enhanced-teaching approaches due to a lack of technological resources, lack of appropriate guidance and training for teachers and school managers. It is necessary to assist teachers in determining appropriate mechanisms for delivering curriculum and utilising technology for teaching activities. The aim of this research is the development of a decision support model of mobile learning technology used for teaching to guide and assist teachers in determining appropriate mobile technology usage mechanisms for teaching and assist school managers in developing and designing the curriculum to be undertaken in the primary school environment. This research collected and analysed data for the requirements of mobile technology-enhanced teaching and developed a novel decision support model of mobile technology-enhanced teaching to guide in planning and delivering curriculum using mobile learning technologies. This study employs a mixed methods approach (quantitative via questionnaire and qualitative via semi-structured interviews) administered in urban and rural areas, in order to identify and analyse data from the teachers’ and school managers’ perspectives on the requirements, and attitudes of mobile technology enhanced-teaching. The results highlight that guidance and training in using mobile technology are necessary for teacher training and for school managers delivering the curriculum. Therefore, teachers and school managers need an appropriate decision support model of MLT to guide and decide when they have to use MLT in order to maximise the use of MLT effectively. Soft System Methodology is used for investigating an unstructured problem and developing a decision support model for this research. Additionally, the testing and evaluation of the effectiveness, efficacy, and efficiency of the experimental model in a real-world environment were collected. Finally, this research develops a novel decision support model for mobile technology-enhanced teaching, which can significantly increase the performance of teachers and school managers in planning and delivering educational systems suitable for teaching with mobile learning technology in primary education in Thailand.

description: Using N=2 superspace techniques we compute the four-loop spectrum of single trace operators in the SU(2) x SU(2) sector of ABJM and ABJ supersymmetric Chern-Simons theories. Our computation yields a four-loop contribution to the function h^2(λ) (and its ABJ generalization) in the magnon dispersion relation which has fixed maximum transcendentality and coincides with the findings in components given in the revised versions of arXiv:0908.2463 and arXiv:0912.3460. We also discuss possible scenarios for an all-loop function h^2(λ) that interpolates between weak and strong couplings.

Gross-Neveu model with O(2)$_L\times$O(2)$_R$ chiral symmetry: Duality with Zakharov-Mikhailov model and large $N$ solution

description: The two-flavor Gross-Neveu model with U(2)$_L\times$U(2)$_R$ chiral symmetry in 1+1 dimensions is used to construct a novel variant of four-fermion theories with O(2)$_L\times$O(2)$_R$ chiral symmetry. The spontaneous breaking of the group O(2), a continuous group with two connected components (rotations and reflections), gives rise to new phenomena. It is ideally suited to describe a situation where two distinct kinds of condensation compete, in particular chiral symmetry breaking (particle-hole condensation) and Cooper pairing (particle-particle condensation). After solving the O(2) chiral Gross-Neveu model in detail, we demonstrate that it is dual to another classically integrable model due to Zakharov and Mikhailov. The duality enables us to solve the quantum version of this model in the large $N$ limit with semiclassical methods, supporting its integrability at the quantum level. The resulting model is the unique four-fermion theory sharing the full Pauli-Gürsey symmetry with free, massless fermions (``perfect Gross-Neveu model") and provides us with a solvable model for competing chiral and Cooper pair condensates, including explicit soliton dynamics and the phase diagram.

description: We present observational constraints on the nature of dark energy using the Supernova Legacy Survey three year sample (SNLS3) of Guy et al. (2010) and Conley et al. (2011). We use the 472 SNe Ia in this sample, accounting for recently discovered correlations between SN Ia luminosity and host galaxy properties, and include the effects of all identified systematic uncertainties directly in the cosmological fits. Combining the SNLS3 data with the full WMAP7 power spectrum, the Sloan Digital Sky Survey luminous red galaxy power spectrum, and a prior on the Hubble constant H0 from SHOES, in a flat universe we find omega_m=0.269+/-0.015 and w=-1.061+0.069-0.068 -- a 6.5% measure of the dark energy equation-of-state parameter w. The statistical and systematic uncertainties are approximately equal, with the systematic uncertainties dominated by the photometric calibration of the SN Ia fluxes -- without these calibration effects, systematics contribute only a ~2% error in w. When relaxing the assumption of flatness, we find omega_m=0.271+/-0.015, omega_k=-0.002+/-0.006, and w=-1.069+0.091-0.092. Parameterizing the time evolution of w as w(a)=w_0+w_a(1-a), gives w_0=-0.905+/-0.196, w_a=-0.984+1.094-1.097 in a flat universe. All of our results are consistent with a flat, w=-1 universe. The size of the SNLS3 sample allows various tests to be performed with the SNe segregated according to their light curve and host galaxy properties. We find that the cosmological constraints derived from these different sub-samples are consistent. There is evidence that the coefficient, beta, relating SN Ia luminosity and color, varies with host parameters at >4sigma significance (in addition to the known SN luminosity--host relation); however this has only a small effect on the cosmological results and is currently a sub-dominant systematic.

Dark exciton energy splitting in monolayer WSe2: insights from time-dependent density-functional theory

description: We present here a formalism based on time-dependent density-functional theory (TDDFT) to describe characteristics of both intra- and inter-valley excitons in semiconductors, the latter of which had remained a challenge. Through the usage of an appropriate exchange-correlation kernel (nanoquanta), we trace the energy difference between the intra- and inter-valley dark excitons in monolayer (1L) WSe2 to the domination of the exchange part in the exchange-correlation energies of these states. Furthermore, our calculated transition contribution maps establish the momentum resolved weights of the electron-hole excitations in both bright and dark excitons thereby providing a comprehensive understanding of excitonic properties of 1L WSe2. We find that the states consist of hybridized excitations around the corresponding valleys which leads to brightening of the dark excitons, i.e., significantly decreasing their lifetime which is reflected in the PL spectrum. Using many-body perturbation theory, we calculate the phonon contribution to the energy bandgap and the linewidths of the excited electrons, holes and (bright) exciton to find that as the temperature increases the bandgap significantly decreases, while the linewidths increase. Our work paves for describing the ultrafast charge dynamics of transition metal dichalcogenide within an ab initio framework.
Viability of MSSM scenarios at very large tan(beta)

description: We investigate the MSSM with very large tan(beta) > 50, where the fermion masses are strongly affected by loop-induced couplings to the "wrong" Higgs, imposing perturbative Yukawa couplings and constraints from flavour physics. Performing a low-energy scan of the MSSM with flavour-blind soft terms, we find that the branching ratio of B->tau nu and the anomalous magnetic moment of the muon are the strongest constraints at very large tan(beta) and identify the viable regions in parameter space. Furthermore we determine the scale at which the perturbativity of the Yukawa sector breaks down, depending on the low-energy MSSM parameters. Next, we analyse the very large tan(beta) regime of General Gauge Mediation (GGM) with a low mediation scale. We investigate the requirements on the parameter space and discuss the implied flavour phenomenology. We point out that the possibility of a vanishing Bmu term at a mediation scale M = 100 TeV is challenged by the experimental data on B->tau nu and the anomalous magnetic moment of the muon.

Production of non-Abelian tensor gauge bosons. Tree amplitudes in generalized Yang-Mills theory and BCFW recursion relation

description: The BCFW recursion relation allows to calculate tree-level scattering amplitudes in generalized Yang-Mills theory and, in particular, four-particle amplitudes for the production rate of non-Abelian tensor gauge bosons of arbitrary high spin in the fusion of two gluons. The consistency of the calculations in different kinematical channels is fulfilled when all dimensionless cubic coupling constants between vector bosons (gluons) and high spin non-Abelian tensor gauge bosons are equal to the Yang-Mills coupling constant. There are no high derivative cubic vertices in the generalized Yang-Mills theory. The amplitudes vanish as complex deformation parameter tends to infinity, so that there is no contribution from the contour at infinity. We derive a generalization of the Parke-Taylor formula in the case of production of two tensor gauge bosons of spin-s and N gluons (jets). The expression is holomorhic in the spinor variables of the scattered particles, exactly as the MHV gluon amplitude is, and reduces to the gluonic MHV amplitude when s=1. In generalized Yang-Mills theory the tree level n-particle scattering amplitudes with all positive helicities vanish, but tree amplitudes with one negative helicity particle are already nonzero.

description: We study the ensemble X-ray variability properties of Active Galactic Nuclei (AGN) over a large range of timescales (20 ks $\leq T\leq$ 14 yrs), redshift ($0\leq z \lesssim 3$), luminosities ($10^{40}$ erg s$^{-1}\leq L_X\leq 10^{46}$ erg s$^{-1}$) and black hole (BH) masses ($10^6 \leq $M$_\odot \leq 10^9$). We propose the use of the variance-frequency diagram, as a viable alternative to the study of the power spectral density (PSD), which is not yet accessible for distant, faint and/or sparsely sampled AGN. We show that the data collected from archival observations and previous literature studies are fully consistent with a universal PSD form which does not show any evidence for systematic evolution of shape or amplitude with redshift or luminosity, even if there may be differences between individual AGN at a given redshift or luminosity. We find new evidence that the PSD bend frequency depends on BH mass and, possibly, on accretion rate. We finally discuss the implications for current and future AGN population and cosmological studies.

description: We have studied the contribution of the state $X(3930)$, coming from the interaction of the $D \overline{D}$ and $D^{+}_s D^{-}_s$ channels, to the $B^- \to K^- J/ψω$ decay. The purpose of this work is to offer a complementary tool to see if the $X(3930)$ state observed in the $D^+ D^-$ channel is the same or not as the $X(3960)$ resonance claimed by the LHCb collaboration from a peak in the $D^{+}_s D^{-}_s$ mass distribution around threshold. We present results for what we expect in the $J/ψω$ mass distribution in the $B^- \to K^- J/ψω$ decay and conclude that a clear signal should be seen around $3930\,\rm MeV$. At the same time, finding no extra resonance signal at $3960\,\rm MeV$ would be a clear indication that there is not a new state at $3960\,\rm MeV$, supporting the hypothesis that the near-threshold peaking structure peak in the $D^{+}_s D^{-}_s$ mass distribution is only a manifestation of a resonance below threshold.

description: We suggest a thick braneworld model in the squared curvature gravity theory. Despite the appearance of higher order derivatives, the localization of gravity and various bulk matter fields is shown to be possible. The existence of the normalizable gravitational zero mode indicates that our four-dimensional gravity is reproduced. In order to localize the chiral fermions on the brane, two types of coupling between the fermions and the brane forming scalar is introduced. The first coupling leads us to a Schrödinger equation with a volcano potential, and the other a Pöschl-Teller potential. In both cases, the zero mode exists only for the left-hand fermions. Several massive KK states of the fermions can be trapped on the brane, either as resonant states or as bound states.

description: In this paper, we consider quantum error correction over depolarizing channels with non-binary low-density parity-check codes defined over Galois field of size $2^p$ . The proposed quantum error correcting codes are based on the binary quasi-cyclic CSS (Calderbank, Shor and Steane) codes. The resulting quantum codes outperform the best known quantum codes and surpass the performance limit of the bounded distance decoder. By increasing the size of the underlying Galois field, i.e., $2^p$, the error floors are considerably improved.

description: The average number of constraints per particle $< C_{total} >$ in mechanically stable systems of Platonic solids (except cubes) approaches the isostatic limit at the jamming point ($< C_{total} > \rightarrow 12$), though average number of contacts are hypostatic. By introducing angular alignment metrics to classify the degree of constraint imposed by each contact, constraints are shown to arise as a direct result of local orientational order reflected in edge-face and face-face alignment angle distributions. With approximately one face-face contact per particle at jamming chain-like face-face clusters with finite extent form in these systems.

Bioadhesion at two scales : a self-adhesion criterion for slanted micropillars and the effects of ATP depletion on the energetics of cell contraction
Creators: name: Kong, Albert
Publisher: name: University of British Columbia
Year: 2022

description: This thesis explores bioadhesion at two scales. In many animals, adhesion plays a critical role to enable their traversal on inclined and inverted surfaces of varying chemistry. This is achieved through arrays of fibrils or micropillars found at the tips of these animals’ appendages. Synthetic mimics inspired by the design of these natural systems are actively developed, studied, and used in applications not limited to adhesion. A common limitation in these mimics is that adjacent micropillars tend to adhere to each other (self-adhere) by lateral van der Waals interactions, impeding on their intended function. Through mathematical modeling, our work demonstrates that slanting micropillars from their vertical arrangement permits them to be longer or more densely packed while avoiding self-adhesion. We derive a criterion to determine the critical angle above which slanting remains beneficial, providing developers of micropillar array devices with a tool to aid in their design. Our analysis further finds that the design of natural micropillar arrays in the ladybird beetle are close to optimal for packing or length, providing justification for the observed natural design. In cell biology, adhesion gives structure to organisms, enabling growth and proliferation. Furthermore, adhesion enables cells to contract against their surroundings, which has been identified as a key factor in cancer progression and metastasis. We developed an experimental platform to alter cellular concentrations of adenosine triphosphate (ATP) – the energetic currency of cells – and measure changes in their contractile response. Our work contributes to existing literature exploring nutritional approaches to cancer therapeutics but also quantifies general metabolic adaptation due to changes in nutrient levels. By processing cell images, we find that glucose deprived cells become less contractile than control cells. Through mathematical modeling, we additionally found that the glucose deprived are 36% less efficient during contraction (they perform 36% less work per ATP consumed). However, by interpolating between the response parameters of glucose deprived and control cells, we postulate that subject to low levels of glucose deprivation, cells maintain and even enhance their contractility and efficiency. Only beyond a critical level of glucose deprivation do both begin to diminish.

description: Very thick films of BiCrO$_3$ have been grown on a SrTiO$_3$ substrate, maintaining a tetragonal lattice up to thicknesses of 14,000Å. Assuming we can treat films of this thickness as bulk crystals, we first calculated the experimentally undetermined atomic positions within the unit cell with the measured lattice constant of the film, then relaxed the lattice constants along with the atomic positions. All the calculations result in an antiferroelectric crystal with the {\it Pnma} space group with noncollinear Bi displacements. We find G-type antiferromagnetism with a spin-orbit induced weak ferromagnetic component, however, the weak ferromagnetic component can cancel if the antiferromagnetic spins are oriented along a particular one of the three 2-fold rotation axes.

description: In this work, we present ænet-PyTorch, a PyTorch-based implementation for training artificial neural network-based machine learning interatomic potentials. Developed as an extension of the atomic energy network (ænet), ænet-PyTorch provides access to all the tools included in ænet for the application and usage of the potentials. The package has been designed as an alternative to the internal training capabilities of ænet, leveraging the power of graphic processing units to facilitate direct training on forces in addition to energies. This leads to a substantial reduction of the training time by one to two orders of magnitude compared to the CPU implementation, enabling direct training on forces for systems beyond small molecules. Here we demonstrate the main features of ænet-PyTorch and show its performance on open databases. Our results show that training on all the force information within a data set is not necessary, and including between 10% to 20% of the force information is sufficient to achieve optimally accurate interatomic potentials with the least computational resources.

description: A superposition rule is a particular type of map that enables one to express the general solution of certain systems of first-order ordinary differential equations, the so-called Lie systems, out of generic families of particular solutions and a set of constants. The first aim of this work is to propose several generalisations of this notion to second-order differential equations. Next, several results on the existence of such generalisations are given and relations with the theories of Lie systems and quasi-Lie schemes are found. Finally, our methods are used to study second-order Riccati equations and other second-order differential equations of mathematical and physical interest.

description: Early optical observations of gamma-ray bursts can significantly contribute to the study of the central engine and physical processes therein. However, of the thousands observed so far, still only a few have data at optical wavelengths in the first minutes after the onset of the prompt emission. Here we report on GRB\,190106A, whose afterglow was observed in optical bands just 36 s after the {\em Swift}/BAT trigger, i.e., during the prompt emission phase. The early optical afterglow exhibits a bimodal structure followed by a normal decay, with a faster decay after $\sim \rm T_{0}+$1 day. We present optical photometric and spectroscopic observations of GRB\,190106A. We derive the redshift via metal absorption lines from Xinglong 2.16-m/BFOSC spectroscopic observations. From the BFOSC spectrum, we measure $z= 1.861\pm0.002$. The double-peak optical light curve is a significant feature predicted by the reverse-forward external shock model. The shallow decay followed by a normal decay in both the X-ray and optical light curves is well explained with the standard forward-shock model with late-time energy injection. Therefore, GRB\,190106A offers a case study for GRBs emission from both reverse and forward shocks.

description: We present a scheme to prepare quantum correlated states of two mechanical systems based on the pouring of pre-available all-optical entanglement into the state of two micro-mirrors belonging to remote and non-interacting optomechanical cavities. We show that, under realistic experimental conditions, the protocol allows for the preparation of a genuine quantum state of a composite mesoscopic system whose non-classical features extend far beyond the occurrence of entanglement. We finally discuss a way to access such mechanical correlations.

description: There are not many tools to quantitatively monitor the emergence of classical geometric features from a quantum spacetime, whose microscopic structure may be a highly quantum-fluctuating "spacetime foam". To improve this situation, we introduce new quantum observables that allow us to measure the absolute and relative homogeneity of geometric properties of a nonperturbative quantum universe, as function of a chosen averaging scale. This opens a new way to compare results obtained in full quantum gravity to descriptions of the early universe that assume homogeneity and isotropy at the outset. Our construction is purely geometric and does not depend on a background metric. We illustrate the viability of the quantum homogeneity measures by a nontrivial application to two-dimensional Lorentzian quantum gravity formulated in terms of a path integral over Causal Dynamical Triangulations, and find some evidence of quantum inhomogeneity.

Circumcentered methods and generalized proximal point algorithms
Creators: name: Ouyang, Hui
Publisher: name: University of British Columbia
Year: 2022

description: This dissertation consists of two parts. Part I concerns circumcentered methods for best approximation or feasibility problems while Part II deals with generalized proximal point algorithms for monotone inclusion problems. The monotone inclusion problem has favourable modelling capability for a large number of applications in optimization. In particular, monotone inclusion problems cover the important class of best approximation and feasibility problems. The circumcentered method has great performance for solving some best approximation or feasibility problems although its iteration mapping, the circumcenter mapping, is in general not globally well-defined. One of the most popular algorithms for solving monotone inclusion problems is the generalized proximal point algorithm. In Part I, we investigate the best approximation mapping that is a generalized version of the circumcenter mapping, explore locally proper circumcenter mappings and circumcentered methods, and consider circumcenters in the framework of general Bregman distances. In Part II, we study the weak, strong, and linear convergence of generalized proximal point algorithms from the following three directions: study the stability of iteration algorithms involving nonexpansive operators; discuss the convergence of relaxation variants of the Krasnosel'skii-Mann iteration; directly work on the convergence of generalized proximal point algorithms by using the beautiful properties of the resolvent of maximally monotone operators.
A Search for OH 18-cm Emission from Intermediate-Velocity Gas at High Galactic Latitudes

description: We present search results of 22 high latitude (b > 25 deg.) sightlines for OH 18-cm emission using the 305-m radio telescope at the Arecibo Observatory. These sightlines appear in neutral hydrogen emission at intermediate velocities (V_lsr values ranging from -90 to -20 km/s) and are predicted to have a sufficient molecular composition so as to be detectable in molecular emission. Such objects, known as Intermediate-Velocity Molecular Clouds (IVMCs), have historically been detected through 12CO emission. Recent studies indicate that IVMCs may be widespread in the Galaxy and have important implications for models of the interstellar medium and star formation. However, we report non-detections of OH emission toward the 22 sightlines and provide stringent upper limits on the OH column density. Using available HI and Av data in combination with existing state-of-the-art PDR models, we estimate H2 column densities and find that they are more than an order of magnitude lower than the predicted values. We also find that the hydrogen volume density of these clouds is less than roughly 25 per cubic centimeter. In addition, we discuss the known IVMCs with previous 12CO detections in the context of the PDR models. Our analysis of these clouds indicates that the structure of molecular material in IVMCs is morphologically clumpy. These results motivate the need for future sensitive, on-the-fly searches (rather than targeted searches) for CO emission from IVMCs with of order roughly 1' resolution. High angular resolution (1') HI and Av data will also be helpful to better constrain the structure and composition of IVMCs.
Coherence in scattering of massive weakly interacting neutral particles off nuclei
Creators: name: Bednyakov, V. A.
Publisher: name: arXiv
Year: 2023
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The paper presents a novel approach to the description of the nonrelativistic weak interaction of a massive neutral particle (lepton) and a nucleus, in which the latter retains its integrity. The cross section of such a process is a sum of the elastic (or coherent) contribution, when the nucleus remains in its original state, and the inelastic (incoherent) contribution, when the nucleus is in an excited state. Smooth transition from elastic scattering to inelastic scattering is governed by the dependence of the nuclear form factors on the momentum transferred to the nucleus. The intensity of the weak interaction is set by the parameters that determine the contributions to the probability amplitude from the scalar products of the leptonic and nucleon currents. The resulting expressions are of interest, at least in the problem of direct detection of neutral massive weakly interacting particles of dark matter, since in this case, in contrast to the generally accepted approach, both elastic and inelastic processes are simultaneously considered. It is shown that the presence of the inelastic contribution accompanied by emission of characteristic radiation (photons) from the deexcitation of the nucleus turns out to be decisive when the coherent cross section is strongly suppressed or cannot be detected. Therefore in order to extract maximum information about dark matter particles, one should plan experiments aimed at the direct detection of dark matter particles in a setting that allows one to detect both the recoil energy of the nucleus and the gamma quanta from the deexcitation of the nucleus.

description: We study the effect of a potential fourth fermion generation on the upper and lower Higgs boson mass bounds. This investigation is based on the numerical evaluation of a chirally invariant lattice Higgs-Yukawa model emulating the same Higgs-fermion coupling structure as in the Higgs sector of the electroweak Standard Model. In particular, the considered model obeys a Ginsparg-Wilson version of the underlying ${SU}(2)_L\times {U}(1)_Y$ symmetry, being a global symmetry here due to the neglection of gauge fields in this model. We present our results on the modification of the upper and lower Higgs boson mass bounds induced by the presence of a hypothetical very heavy fourth quark doublet. Finally, we compare these findings to the standard scenario of three fermion generations.
