Electronic transport in twisted double bilayer graphene
Creators: name: Vishnu Radhan, Aswin
Publisher: name: University of British Columbia
Year: 2020

description: Two dimensional (2D) van der Waals materials with a lattice mismatch or a relative twist angle, stacked atop each other forms a moiré superlattice. The electronic properties of such a system can be modified by controlling the relative twist angle between the layers, the most famous example being magic-angle twisted bilayer graphene. Since the observation of correlated insulator states and superconductivity in this flat band moiré system, investigations on other 2D moiré systems has gathered pace. Two Bernal stacked bilayer graphene sheets twisted relative to each other, i.e., twisted double bilayer graphene, gives the additional opportunity of tuning the electronic structure by a displacement electric field. This thesis presents the fabrication and electrical transport measurements of twisted double bilayer graphene devices. In order to compare the efficacy of various fabrication techniques, we fabricated the devices using two different modified dry transfer techniques: “tear-and-stack” and “cut-and-stack”. By calculating the twist angles from the electrical transport data, we find the “cut-and-stack” technique to give a better control of the twist angle of the fabricated devices. Subsequently, we studied the transport properties of a device with a twist angle of 1.39 degree, in order to replicate the electronic phase diagram of twisted double bilayer graphene devices. Tuning the displacement electric field and carrier density independently in a double gated geometry, we were able to observe correlated insulating states at quarter, half and three-quarter filling of the moiré band for a range of electric field values. The evolution of these insulating states in an in-plane magnetic field suggests spin/valley polarization. Additionally, the metallic states surrounding the correlated insulating state at half-filling displays a strong temperature dependence and nonlinear current-voltage characteristics, the nature of which remains ambiguous in our measurements.

Two and three-point correlators of operators dual to folded string solutions at strong coupling

Subjects: subject: High Energy Physics - Theory (hep-th)

description: A particular analytic continuation of classical string solutions having a single AdS_5 spin is considered. These solutions describe strings tunnelling from the boundary to the boundary of AdS_5. We use the Legendre transform of the dimensionally regularised action of these solutions to evaluate the 2-point functions of the dual operators, holographically. Subsequently, we evaluate the structure coefficient of correlators involving two operators with spin S and a BPS state, at strong coupling. Our expressions are valid for any value of the AdS spin S/\sqrtλ and can be applied both at the case of long and short strings. For long strings and at leading order, the structure coefficient is independent of the spin S for twist J operators, while it scales as 1/\log^l{\frac{S}{\sqrtλ}} for the case of operators with two equal angular momenta in S^5. For short strings, the structure coefficient is proportional to the energy E of the string. Finally, we comment on the possibility of relating the strong coupling 3-point function coefficient of three large spin twist 2 operators to the action of the 6-gluon scattering amplitude.

description: Cryogenically cooled buffer gas beam sources of the molecule thorium monoxide (ThO) are optimized and characterized. Both helium and neon buffer gas sources are shown to produce ThO beams with high flux, low divergence, low forward velocity, and cold internal temperature for a variety of stagnation densities and nozzle diameters. The beam operates with a buffer gas stagnation density of ~10^15-10^16 cm^-3 (Reynolds number ~1-100), resulting in expansion cooling of the internal temperature of the ThO to as low as 2 K. For the neon (helium) based source, this represents cooling by a factor of about 10 (2) from the initial nozzle temperature of about 20 K (4 K). These sources deliver ~10^11 ThO molecules in a single quantum state within a 1-3 ms long pulse at 10 Hz repetition rate. Under conditions optimized for a future precision spectroscopy application [A C Vutha et al 2010 J. Phys. B: At. Mol. Opt. Phys. 43 074007], the neon-based beam has the following characteristics: forward velocity of 170 m/s, internal temperature of 3.4 K, and brightness of 3x10^11 ground state molecules per steradian per pulse. Compared to typical supersonic sources, the relatively low stagnation density of this source, and the fact that the cooling mechanism relies only on collisions with an inert buffer gas, make it widely applicable to many atomic and molecular species, including those which are chemically reactive, such as ThO.

Parents’ experiences of participating in PEERS : a social skills intervention for adolescents with autism spectrum disorder
Creators: name: Thompson, Brittni
Publisher: name: University of British Columbia
Year: 2020

description: As many as 26 to 76% of people with autism spectrum disorder (ASD) live isolated and restricted lives (Cederlund et al., 2008). This outcome is often attributed to impaired social skills that interfere with quality of life, employment, and the ability to develop and maintain relationships. Effective social skills interventions are critical for addressing challenges and negative outcomes associated with impaired social skill development in individuals with ASD. The literature on social skills interventions highlights positive intervention outcomes for adolescents with ASD, but few studies have asked parents about their experiences in parent mediated social skills interventions (Karst et al., 2015). This research was conducted to gain an understanding of the barriers and facilitators of parent’s experiences of participating in and implementing the Program for the Education and Enrichment of Relationship Skills (PEERS), a parent-mediated social skills intervention for adolescents with ASD. Six parents of adolescents diagnosed with ASD were interviewed and asked to identify and describe experiences that helped them or hindered them and experiences that they still desired or wished for (i.e., Wishlist items). Interview transcripts were analyzed using the Enhanced Critical Incident Technique (ECIT; Butterfield et al., 2009). Critical Incidents extracted from transcripts and categories that were developed during the analysis were subjected to rigorous reliability and validity checks, including analysis by another researcher, inter-rater agreement, and participant feedback. From the interview transcripts, 155 Critical Incidents (CIs) were generated, including 63 Helpful CIs, 39 Hindering CIs, and 53 Wishlist items. Critical incidents were organized into six emergent categories: Language and communication, Content, Connection to Others, Confidence, Continuity and Enhancements. These findings are reflective of literature on parents’ perspectives of support needed for raising a child with autism and their wants for social competence programs. Finally, practical implications, study contributions, limitations, and directions for future research are discussed.

Growth instability due to lattice-induced topological currents in limited mobility epitaxial growth models

description: The energetically driven Ehrlich-Schwoebel (ES) barrier had been generally accepted as the primary cause of the growth instability in the form of quasi-regular mound-like structures observed on the surface of thin film grown via molecular beam epitaxy (MBE) technique. Recently the second mechanism of mound formation was proposed in terms of a topologically induced flux of particles originating from the line tension of the step edges which form the contour lines around a mound. Through large-scale simulations of MBE growth on a variety of crystalline lattice planes using limited mobility, solid-on-solid models introduced by Wolf-Villain and Das Sarma-Tamborenea in 2+1 dimensions, we propose yet another type of topological uphill particle current which is unique to some lattice, and has hitherto been overlooked in the literature. Without ES barrier, our simulations produce spectacular mounds very similar, in some cases, to what have been observed in many recent MBE experiments. On a lattice where these currents cease to exist, the surface appears to be scale-invariant, statistically rough as predicted by the conventional continuum growth equation.

description: We report a technique for applying a dc voltage or current bias to the center conductor of a high-quality factor superconducting microwave cavity without significantly disturbing selected cavity modes. This is accomplished by incorporating dc bias lines into the cavity at specific locations. The measured S-matrix parameters of the system are in good agreement with theoretical predictions and simulations. We find that at 4 K the quality factor of the cavity degrades by less than 1% under the application of a dc bias.

description: L’obbiettivo della ricerca è quello di introdurre il disegno scientifico all’interno del percorso didattico delle scienze naturali nel ciclo di SM al fine di determinare la funzione del disegno scientifico, come strumento di riflessione, apprendimento e comunicazione tra pari e docente, sia dal punto di vista grafico pittorico sia dal punto di vista disciplinare. Due classi di prima media hanno affrontato alcuni temi degli ambiti di competenza che riguardano la materia e le sue trasformazioni, e gli esseri viventi e gli ecosistemi. A partire dalle idee degli allievi sui temi di studio, sono stati proposti due itinerari didattici impostati per introdurre la visualizzazione scientifica come strategia d’apprendimento. I disegni prodotti dagli allievi della prima classe di sperimentazione mostrano che nel corso delle attività vi è stato un miglioramento qualitativo dal punto di vista grafico pittorico, che ha permesso una positiva comunicazione tra pari. Le valutazioni tra allievi sulle loro produzioni presentano due tipologie di caratteri: generico o specifico. Nella seconda classe, il miglioramento qualitativo dal punto di vista dell’espressione grafica è stato accompagnato da una migliore comprensione dei concetti scientifici e la presa di coscienza dell’utilità dell’illustrazione scientifica per l’apprendimento e la comunicazione. Gli esiti della ricerca hanno mostrato come il ricorso al disegno nell’educazione scientifica usato come strategia didattica per favorire la riflessione e la comunicazione, possa portare concreti benefici per strutturare le conoscenze scientifiche e si riveli un valido strumento per sviluppare il pensiero sistemico.

description: High energy scattering processes involving jets generically involve matrix elements of light- like Wilson lines, known as soft functions. These describe the structure of soft contributions to observables and encode color and kinematic correlations between jets. We compute the dijet soft function to O(α_s^2) as a function of the two jet invariant masses, focusing on terms not determined by its renormalization group evolution that have a non-separable dependence on these masses. Our results include non-global single and double logarithms, and analytic results for the full set of non-logarithmic contributions as well. Using a recent result for the thrust constant, we present the complete O(α_s^2) soft function for dijet production in both position and momentum space.

description: Abstract: More than four years of HERMES observations have confirmed KIC 6951642 is a very long orbit (≈1770 d) single-lined spectroscopic binary (F0-type) with a fast-rotating companion (vsin i = 123±3 Km/s). The Fourier spectrum of its four-year photometric observations includes plenty of significant frequencies (594) in low- and high-frequency regions. The high-frequency modes appear with various time-delay patterns. We detected several rotationally split 𝛿 Scuti pulsations centered at 13.96 per day (and average frequency spacing of Δ𝑓= 0.723±0.006 per day) for KIC 6951642. The detailed study of all significant low frequencies, extended from 0.72 to 3.60 per day, revealed that the two most dominant frequencies (with the same amplitude and larger than of p-modes) are a combination of the lowest-frequency modes (𝑓3 = 𝑓< 0.17 per day), i.e. 𝑓orhrm + 𝑚𝑓orhrm (𝑚 = 12,14). We suggest the lowest-frequency modes are very large harmonics (orders of 10) of orbital frequency (≈0.0006 per day). We verified the other most dominant low-frequencies as harmonics of rota3on frequency 0.721 per day and its combinations. Finally, we reject the probability of hybrid pulsations in the fast-rotating companion of KIC 6951642. We introduce it as a 𝛿 Scuti pulsator with a candidate rotation frequency of 0.721 per day.

description: We study the classical second law of black hole thermodynamics, for Lovelock theories (other than General Relativity), in arbitrary dimensions. Using the standard formula for black hole entropy, we construct scenarios involving the merger of two black holes in which the entropy instantaneously decreases. Our construction involves a Kaluza-Klein compactification down to a dimension in which one of the Lovelock terms is topological. We discuss some open issues in the definition of the second law which might be used to compensate this entropy decrease.

Habitability and loss of hydrogen-helium atmospheres of small planets - the K dwarf advantage
Creators: name: Poppenhaeger, Katja
Publisher: name: Zenodo
Year: 2021

description: Contributed talk at PLATO Mission Conference 2021. Abstract: Evaporation of hydrogen and helium is now directly observable for exoplanets of Jupiter and Neptune size, by using high-resolution spectral observations in the ultraviolet and in the infrared. For even smaller planets, the ongoing loss of a primordial hydrogen-helium atmosphere has not been directly observed yet, but is thought to be relevant for the formation of a habitable atmosphere for life as we know it. The observability of helium escape depends critically on an exoplanet's irradiation in the high-energy regime. M dwarfs, typically a favourite target for habitable zone exoplanet observations, are at a disadvantage here due to their coronal elemental abundance patterns. However, K dwarfs present a suitable starting point for detecting helium escape from planets in their habitable zones, due to their favorable coronal abundances and their higher magnetic activity level compared to G dwarfs. I will discuss relevant examples and outline the impact that modern high-energy surveys can have on the optimal target selection for observing exoplanetary atmospheric escape.

description: The ABC-stacked N-layer-graphene family of two-dimensional electron systems is described at low energies by two remarkably flat bands with Bloch states that have strongly momentum-dependent phase differences between carbon pi-orbital amplitudes on different layers, and large associated momentum space Berry phases. These properties are most easily understood using a simplified model with only nearest-neighbor inter-layer hopping which leads to gapless semiconductor electronic structure, with p^N dispersion in both conduction and valence bands. We report on a study of the electronic band structures of trilayers which uses ab initio density functional theory and k*p theory to fit the parameters of a pi-band tight-binding model. We find that when remote interlayer hopping is retained, the triple Dirac point of the simplified model is split into three single Dirac points located along the three KM directions. External potential differences between top and bottom layers are strongly screened by charge transfer within the trilayer, but still open an energy gap at overall neutrality.

description: In this paper, we give a lower bound for the spectrum of the Laplacian on minimal hypersurfaces immersed into $H^m \times R$. As an application, in dimension 2, we prove that a complete minimal surface with finite total extrinsic curvature has finite index. On the other hand, for stable, minimal surfaces in $H^3$ or in $H^2 \times \R$, we give an upper bound on the infimum of the spectrum of the Laplacian and on the volume growth.
NIRPS: the Near-InfraRed Planet Searcher joining HARPS on the 3.6-m
Creators: name: Grieves, Nolan
Publisher: name: Zenodo
Year: 2021

description: The Near-InfraRed Planet Searcher (NIRPS) is designed to be an
 ultra-stable infrared spectrograph to be installed on ESO’s 3.6 m Telescope
 in La Silla, Chile. NIRPS is an adaptive optics (AO) fiber-fed spectrograph
 operating from 0.98 to 1.8 μm and will be operated simultaneously with the
 optical high-resolution spectrograph HARPS. NIRPS can operate in two modes
 fed by two different fiber links permanently mounted at the Cassegrain focus
 that use either 0.4 arcsecond-fibers for the High Accuracy Mode (HAM) or 0.9
 arcsecond-fibers for the High Efficiency Mode (HEM). The wavelength range of
 NIRPS is optimal for low-mass M dwarfs and the simultaneous NIRPS and HARPS
 observations will improve stellar activity filtering methods given their
 different wavelength coverages. The NIRPS front-end and AO system were
 already tested on-sky at La Silla. The spectrograph and back-end is to be
 shipped to La Silla and installed by end of 2021. Already we have adapted the
 state-of-the-art ESPRESSO data reduction pipeline for NIRPS, obtained
 accurate wavelength solutions with a Uranium Neon lamp, and obtained drift
 stability results below 50 cm/s with a Fabry–Pérot etalon. We discuss the
 current and expected instrument performance and the expected science results
 of NIRPS.
Comprehensive analysis of current PKU management practices and associated patient and parent-reported outcomes in Canada
Creators: name: Yuskiv, Nataliya
Publisher: name: University of British Columbia
Year: 2020

description: Phenylketonuria (PKU) is a genetic metabolic disorder requiring life-long treatment to prevent severe neurocognitive disability. Despite early treatment, suboptimal neurobehavioral outcomes are common in individuals with PKU. The Canadian Inherited Metabolic Diseases Research Network (CIMDRN) presented an opportunity to investigate current approaches to care and associated outcomes in children with PKU and their parents. Four studies were conducted herein. The surveys of Canadian metabolic dietitians and physicians, described in Chapter 2, helped to understand current PKU management practices from the perspectives of healthcare providers. Data reflecting practices in metabolic treatment centres and associated outcomes were derived from the CIMDRN clinical longitudinal PKU database (Chapter 3). Finally, parent-reported child’s health and parental quality of life were analyzed in connection to the quality of metabolic control (Chapter 4). Providers’ surveys identified overall compliance with current PKU guidelines. Variation was found in case ascertainment, diagnostic workup (neonatal BH4 loading test), monitoring and follow up tests (neuropsychological assessments), treatment practices (sapropterin and large neutral amino acids, LNAA) and organization of care in metabolic centres. The mean phenylalanine (Phe) levels were within the recommended range of 120-360 µmol/L but increased (to 331±151 µmol/L) beyond 7 years of age for children with classic PKU. Among children with classic PKU, 32% were considered in good metabolic control by the 4th week of life. This increased to 55% by age 4-5 and declined to 28% at 8-9 years. Tiredness, lack of concentration, irritability and moodiness were reported as moderate symptoms in children. Parents reported considerable guilt due to non-adherence to the diet/supplements, their child’s anxiety, and practical impact of dietary protein restriction. Overall, healthcare providers follow the published guidelines in providing care for their patients. However, this work has identified variation in many areas of PKU nutritional and clinical management practices in Canadian metabolic centres, including diagnostic and follow up nutritional and clinical management practices. This variation has the potential to impact patients’ long-term health outcomes. The most variation was in areas of practice that were not strongly supported by empirical evidence. This knowledge will serve to further optimize health and quality of life outcomes in Canadian children with PKU.

description: Riflettendo sull’importante ruolo che il suono delle parole ha nella poesia, sulla fruizione dei testi poetici e su come poter avvicinare un lettore “standard” alla poesia e ai suoi aspetti ritmici e sonori, mi sono posta le seguenti domande: È possibile rappresentare e comunicare gli aspetti fonetico- ritmici della poesia narrata in un sistema visivo di segni simultaneo? E che impatto avrebbe sui livelli di percezione ed esperienza del lettore? Lo porterebbe ad essere maggiormente immerso nella lettura e a manifestare un interesse verso gli aspetti sonori della poesia? E come fruire questo tipo di contenuti? Il supporto classico del libro sarebbe sempre idoneo, o vi sono altri espedienti? La mia tesi si focalizza sul trovare delle risposte a queste domande, attraverso la visualizzazione di dati fonetici e sonori della voce narrante della poesia, prendendo come caso di studio la voce di Fabio Pusterla

description: The Fermi-contact interaction that characterizes collisional spin exchange of a noble gas with an alkali-metal vapor also gives rise to NMR and EPR frequency shifts of the noble-gas nucleus and the alkali-metal atom, respectively. We have measured the enhancement factor $κ_{0}$ that characterizes these shifts for Rb-$^{129}$Xe in the high-pressure limit to be 493$\pm$31, making use of the previously measured value of $κ_{0}$ for Rb-$^{3}$He. This result allows accurate $^{129}$Xe polarimetry with no need to reference a thermal-equilibrium NMR signal.
