description: The quantum anomalous Hall effect has been theoretically predicted and experimentally verified in magnetic topological insulators. In addition, the surface states of these materials exhibit a hedgehog-like "spin" texture in momentum space. Here, we apply the previously formulated low-energy model for Bi$_2$Se$_3$, a parent compound for magnetic topological insulators, to a slab geometry in which an exchange field acts only within one of the surface layers. In this sample set up, the hedgehog transforms into a skyrmion texture beyond a critical exchange field. This critical field marks a transition between two topologically distinct phases. The topological phase transition takes place without energy gap closing at the Fermi level and leaves the transverse Hall conductance unchanged and quantized to $e^2/2h$. The momentum-space skyrmion texture persists in a finite field range. It may find its realization in hybrid heterostructures with an interface between a three-dimensional topological insulator and a ferromagnetic insulator.

description: The merging system SIT 45 (UGC 12589) is an unusual isolated galaxy triplet, consisting of three merging late-type galaxies, out of 315 systems in the SIT (SDSS-based catalogue of Isolated Triplets). The main aims of this work are to study its dynamical evolution and star formation history (SFH), as well as its dependence on its local and large-scale environment. To study its dynamics, parameters such as the velocity dispersion ($σ_{v}$), the harmonic radius ($R_{H}$), the crossing time ($H_0t_c$), and the virial mass ($M_{vir}$), along with the compactness of the triplet ($S$) were considered. To constrain the SFH, we used CIGALE to fit its observed spectral energy distribution using multi-wavelength data from the ultraviolet to the infrared. According to its SFH, SIT 45 presents star-formation, where the galaxies also present recent ($\sim $200 Myr) star-formation increase, indicating that this activity may have been triggered by the interaction. Its dynamical configuration suggests that the system is highly evolved in comparison to the SIT. However this is not expected for systems composed of star-forming late-type galaxies, based on observations in compact groups. We conclude that SIT 45 is a system of three interacting galaxies that are evolving within the same dark matter halo, where its compact configuration is a consequence of the on-going interaction, rather than due to a long-term evolution (as suggested from its $H_0t_c$ value). We consider two scenarios for the present configuration of the triplet, one where one of the members is a tidal galaxy, and another where this galaxy arrives to the system after the interaction. Both scenarios need further exploration. The isolated triplet SIT 45 is therefore an ideal system to study short timescale mechanisms ($\sim 10^8$ years), such as starbursts triggered by interactions which are more frequent at higher redshift.

description: Despite the ability of the cosmological concordance model ($Λ$CDM) to describe the cosmological observations exceedingly well, power law expansion of the Universe scale radius, $R(t)\propto t^n$, has been proposed as an alternative framework. We examine here these models, analyzing their ability to fit cosmological data using robust model comparison criteria. Type Ia supernovae (SNIa), baryonic acoustic oscillations (BAO) and acoustic scale information from the cosmic microwave background (CMB) have been used. We find that SNIa data either alone or combined with BAO can be well reproduced by both $Λ$CDM and power law expansion models with $n\sim 1.5$, while the constant expansion rate model $(n=1)$ is clearly disfavored. Allowing for some redshift evolution in the SNIa luminosity essentially removes any clear preference for a specific model. The CMB data are well known to provide the most stringent constraints on standard cosmological models, in particular, through the position of the first peak of the temperature angular power spectrum, corresponding to the sound horizon at recombination, a scale physically related to the BAO scale. Models with $n\geq 1$ lead to a divergence of the sound horizon and do not naturally provide the relevant scales for the BAO and the CMB. We retain an empirical footing to overcome this issue: we let the data choose the preferred values for these scales, while we recompute the ionization history in power law models, to obtain the distance to the CMB. In doing so, we find that the scale coming from the BAO data is not consistent with the observed position of the first peak of the CMB temperature angular power spectrum for any power law cosmology. Therefore, we conclude that when the three standard probes are combined, the $Λ$CDM model is very strongly favored over any of these alternative models, which are then essentially ruled out.

description: Background:There is a significant global disparity on the provision of palliative care services for individuals with life-limiting illnesses and palliative care remains an urgent, neglected need in developing countries. In Ethiopia, there is a paucity of information on the patient's perception about palliative care and the factors influencing the likelihood of service utilization among adult cancer patients. Objectives: To assess the perception about palliative care and factors influencing the likelihood of service utilization among adult cancer patients in Tikur Anbessa Specialized Hospital, Ethiopia from January 1to March 31, 2019. Methods: A facility-based cross-sectional study conducted among 304 systematically selectedadult cancer patients in the cancer unit of Tikur Anbessa Specialized Hospital. A pretested structured interviewer-administered questionnaire was used for data collection. Multivariable binary logistic regression model was carried out to control for the potential confounders and to identify the independent factors associated with palliative care service utilization. P-value <0.05 was used to declare statistical significance and goodness of fit of the model assessed using Hosmer and Lemeshow goodness of fit test. Results:A little more than half of the patients had aperception on the availability of palliative care service174(57.2%), adult cancer patients who earn≥ 1,500-birrs monthly income were 2.36 times more likely to utilize palliative care service as compared to their counterparts who earn a monthly income of <1,500 birrs (AOR=2.36, 95% CI 1.37,4.06), after controlling the effect of other covariates. Similarly, having family members of more than two was associated with higher utilization (AOR=2.28, 95% CI 1.02,5.13) Conclusion and recommendations: Significant number of adult cancer patients were nothaving perception about utilizing palliative care service and higher monthly income and having more than two family memberswere the factors strongly associated with higher likelihood of palliativecare service utilization. Multiple stakeholders should be involved in reducing the financial constraints that hinder patients not to utilize palliative care service and to improve social support for those who have few or no family members.

description: Calculations of the reaction rate of the proton radiative capture on 3H at temperatures from 0.01 T9 up to 5 T9, which are based on the theoretical results for the astrophysical S-factor and take into account the latest experimental data, were carried out. Theoretical results for the S-factor at energies from 1 keV up to 5 MeV were obtained in the framework of the modified potential cluster model with the classification of orbital states according to Young tableaux. On the basis of used nuclear model of the interaction of p and 3H particles there was shown possibility of description the latest experimental data for the S-factor at the energy range from 50 keV up to 5 MeV.

On the motion of free interface in ideal incompressible MHD

Subjects: subject: Analysis of PDEs (math.AP)

description: For the free boundary problem of the plasma-vacuum interface to three-dimensional ideal incompressible magnetohydrodynamics (MHD), the a priori estimates of smooth solutions are proved in Sobolev norms by adopting a geometrical point of view and some quantities such as the second fundamental form and the velocity of the free interface are estimated. In the vacuum region, the magnetic fields are described by the div-curl system of pre-Maxwell dynamics, while at the interface the total pressure is continuous and the magnetic fields are tangent to the interface, but we do not need any restrictions on the size of the magnetic fields on the free interface. We introduce the "virtual particle" endowed with a virtual velocity field in vacuum to reformulate the problem to a fixed boundary problem under the Lagrangian coordinates. The $L^2$-norms of any order covariant derivatives of the magnetic fields both in vacuum and on the boundaries are bounded in terms of initial data and the second fundamental forms of the free interface and the rigid wall. The estimates of the curl of the electric fields in vacuum are also obtained, which are also indispensable in elliptic estimates.

description: Due to the mirror symmetry breaking, chiral structures show fantastic electromagnetic (EM) properties involving negative refraction, giant optical activity, and asymmetric transmission. Aligned electric and magnetic dipoles excited in chiral structures contribute to extraordinary properties. However, the chiral structures that exhibit n-fold rotational symmetry show limited tuning capability. In this paper, we proposed a compact, light, and highly tunable anisotropic chiral structure to overcome this limitation and realize a linear-to-circular polarization conversion. The anisotropy is due to simultaneous excitations of two different pairs of aligned electric and magnetic dipoles. The 3D omega-like structure, etched on two sides of one PCB board and connected by metallic vias, achieves 60% of linearto- circular conversion (transmission) efficiency at the operating frequency of 9.2 GHz. The desired 90-degree phase shift between the two orthogonal linear polarization components is not only from the finite-thickness dielectric substrate but also from the anisotropic chiral response slightly off the resonance. The work enables elegant and practical polarization control of EM waves.

description: Young stellar populations provide a record of past star formation, and by establishing their members' dynamics and ages, it is possible to reconstruct the full history of star formation events. Gaia has greatly expanded the number of accessible stellar populations, with one of the most notable recently-discovered associations being Cepheus Far North (CFN), a population containing hundreds of members spanning over 100 pc. With its proximity (d $\lesssim$ 200 pc), apparent substructure, and relatively small population, CFN represents a manageable population to study in depth, with enough evidence of internal complexity to produce a compelling star formation story. Using Gaia astrometry and photometry combined with additional spectroscopic observations, we identify over 500 candidate CFN members spread across 7 subgroups. Combining ages from isochrones, asteroseismology, dynamics, and lithium depletion, we produce well-constrained ages for all seven subgroups, revealing a largely continuous 10 Myr star formation history in the association. By tracing back the present-day populations to the time of their formation, we identify two spatially and dynamically distinct nodes in which stars form, one associated with $β$ Cephei which shows mostly co-spatial formation, and one associated with EE Draconis with a more dispersed star formation history. This detailed view of star formation demonstrates the complexity of the star formation process, even in the smallest of regions.

Polytropic behavior in the structures of Interplanetary Coronal Mass Ejections

description: The polytropic process characterizes the thermodynamics of space plasma particle populations. The polytropic index, $γ$, is particularly important as it describes the thermodynamic behavior of the system by quantifying the changes in temperature as the system is compressed or expanded. Using Wind spacecraft plasma and magnetic field data during $01/1995 - 12/2018$, we investigate the thermodynamic evolution in 336 Interplanetary Coronal Mass Ejection (ICME) events. For each event, we derive the index $γ$ in the sheath and magnetic ejecta structures, along with the pre- and post- event regions. We then examine the distributions of all $γ$ indices in these four regions and derive the entropic gradient of each, which is indicative of the ambient heating. We find that in the ICME sheath region, where wave turbulence is expected to be highest, the thermodynamics takes longest to recover into the original quasi-adiabatic process, while it recovers faster in the quieter ejecta region. This pattern creates a thermodynamic cycle, featuring a near adiabatic value $γ$ ~ $γ$${_a}$ (=5/3) upstream of the ICMEs, $γ$${_a}$ - $γ$ ~ 0.26 in the sheaths, $γ$${_a}$ - $γ$ ~ 0.13 in the ICME ejecta, and recovers again to $γ$ ~ $γ$${_a}$ after the passage of the ICME. These results expose the turbulent heating rates in the ICME plasma: the lower the polytropic index from its adiabatic value and closer to its isothermal value, the larger the entropic gradient, and thus, the rate of turbulent heating that heats the ICME plasma.

description: Let $K$ be a field of characteristic $p > 0$ and let $G$ be a subgroup of $K^\ast \times K^\ast$ with $\text{dim}_\mathbb{Q}(G \otimes_\mathbb{Z} \mathbb{Q}) = r$ finite. Then Voloch proved that the equation $ax + by = 1 \text{ in } (x, y) \in G$ for given $a, b \in K^\ast$ has at most $p^r(p^r + p - 2)/(p - 1)$ solutions $(x, y) \in G$, unless $(a, b)^n \in G$ for some $n \geq 1$. Voloch also conjectured that this upper bound can be replaced by one depending only on $r$. Our main theorem answers this conjecture positively. We prove that there are at most $31 \cdot 19^{r + 1}$ solutions $(x, y)$ unless $(a, b)^n \in G$ for some $n \geq 1$ with $(n, p) = 1$. During the proof of our main theorem we generalize the work of Beukers and Schlickewei to positive characteristic, which heavily relies on diophantine approximation methods. This is a surprising feat on its own, since usually these methods can not be transferred to positive characteristic.

description: To recreate the cosmological models, we employed the parametrization approach in modified teleparallel Gauss-Bonnet gravity. It has been interesting to apply the parametrization approach to investigate cosmological models. The real benefit of using this method is that the observational data may be incorporated to examine the cosmological models. Several cosmological parameters were examined, such as the Hubble parameter (H), the deceleration parameter (q), and the equation of state (EoS) parameter (w). The results obtained are consistent with recent cosmological findings in the conventional scenario. A transition scenario from a decelerating stage to an accelerating stage of cosmic evolution has been observed. The EoS parameter is also in the quintessence phase, which drives the accelerating expansion of the Universe. Also, we look at the violation of strong energy condition, which has become inevitable in the context of modified gravitational theory. Finally, we have performed the Om(z) diagnostic and also obtained the age of the Universe by using the data from the cosmological observations.

Assessement of Late Entry to Antenatal Care and Its Predictors among ANC Attendees in Gambella Region
Creators: name: Endashaw, Tariku
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2010

description: Background: Antenatal care is more beneficial in preventing adverse pregnancy outcomes when it is sought early in the pregnancy and continued through to delivery. Despite the widespread availability of free antenatal care services, most women in our country attend their first antenatal clinic late in pregnancy and fail to return for follow up care, which potentially leads to perinatal and maternal complications. Objective: The objective of the study is to assess late antenatal care booking and its predictors among pregnant women attending antenatal care in selected public health institution in Gambella Region, South West of Ethiopia. Methods: Facility based crossectional study was conducted from March 15 to April 30, 2010 on selected samples 302 pregnant women attending antenatal care. Data were, collected through pretested structured questionnaire, entered in to Epi-info version 3.4 and then exported to SPSS-15 windows statistical packages for analysis. Bivariate and multivariate logistic regression was employed in order to infer associations and predictions. Result: Forty eight percent of women commenced ANC after 16 weeks of gestation. The mean gestational age at booking was 4.6±1.4 months. When the effects of other independent variables on gestational age at booking were controlled, the following characteristics were found to be predictive of failure to initiate antenatal care by 16 weeks of gestation (P<0.05): unplanned pregnancy [AOR=2.85,95%CI (1.274,6.355)], past booking experience of antenatal care after 16weeks of gestation[AOR=5.85,95%CI( 2.665,12.83)], reason for booking was thought the time was appropriate[AOR=2.15,95%CI( 1.052,4.38)]. Conclusion: A significant proportion of mothers commenced antenatal care after 16 weeks of gestation in their pregnancies. It is concluded that unplanned pregnancy and the above two factors were a predictive of late entry to antenatal care in Gambella. These findings indicate that the importance of early antenatal booking is yet to be promoted

description: Variability is a commonly observed property of classical Be stars (CBe) stars. In extreme cases, complete disappearance of the Hα emission line occurs, indicating a disc-less state in CBe stars. The disc-loss and reappearing phases can be identified by studying the Hα line profiles of CBe stars on a regular basis. In this paper, we present the study of a set of selected 9 bright CBe stars, in the wavelength range of 6200 - 6700 Å, to better understand their disc transient nature through continuous monitoring of their Hα line profile variations for 5 consecutive years (2015 -- 2019). Based on our observations, we suggest that 4 of the program stars (HD 4180, HD 142926, HD 164447 and HD 171780) are possibly undergoing disc-loss episodes, whereas one other star (HD 23302) might be passing through disc formation phase. The remaining 4 stars (HD 237056, HD 33357, HD 38708 and HD 60855) have shown signs of hosting a stable disc in recent epochs. Through visual inspection of the overall variation observed in the Hα EW for these stars, we classified them into groups of growing, stable and dissipating discs, respectively. Moreover, our comparative analysis using the BeSS database points out that the star HD 60855 has passed through a disc-less episode in 2008, with its disc formation happening probably over a timescale of only 2 months, between January and March 2008.

description: Obtaining phenotypic measures of feed efficiency requires measuring intake levels and growth rates over a period of approximately 8 weeks (2 weeks of adaption and 6 of measurement), which is expensive and low-throughput. Rumen microbial community (RMC) profiles have shown to be associated with feed efficiency traits in ruminants and so may be a suitable proxy. Using a dataset of 1298 animals across 4 genetically linked flocks that were measured through a feed intake facility (FIF), we predicted feed efficiency from RMC profiles and obtained higher prediction accuracies compared to host genomic prediction. The genetic and phenotypic correlations between feed efficiency traits measured from the FIF and predicted from RMC profiles were estimated as 0.64 and 0.33 for mid-trial intake and 0.47 and 0.30 for residual feed intake (RFI). These results suggest RMC profiles have the potential to be used as a proxy for feed efficiency traits in ruminants.

For the anisotropy two different kinds of local anisotropic $σ=p_t-p_r$ are considered, where $p_t$ and $p_r$ are respectively the tangential and the radial pressure: one that is null at the star's surface defined by $p_r(R)=0$, and one that is nonnull on at the surface, namely, $σ_s=0$ and $σ_s\neq0$. In the case $σ_s=0$, the maximum mass value and the zero frequency of oscillation are found at the same central energy density, indicating that the maximum mass marks the onset of the instability. For the case $σ_s\neq0$, we show that the maximum mass point and the zero frequency of oscillation coincide in the same central energy density value only in a sequence of equilibrium configurations with the same value of $σ_s$. Thus, the stability star regions are determined always by the condition $dM/dρ_c>0$ only when the tangential pressure is maintained fixed at the star surface's $p_t(R)$. These results are also quite important to analyze the stability of other anisotropic compact objects such as neutron stars, boson stars and gravastars.

description: Background: Breast cancer is a major life-threatening public health problem of great concern, with more than one million cases occurringworldwide annually. In Ethiopia breast cancer is the second most often occurring cancer among women. Even though there were studies that were done on risk factors of breast cancer worldwide there are very few studies in developing country especially in Ethiopia. Clarifying the role of non- breastfeeding in developing breast cancer may be helpful to establish preventive and control program to reduce the occurrence of the disease and serve as a baseline for further studies. Objectives: To assess the association between non breastfeeding practices and breast cancer development among patients who are on chemotherapy or radiotherapy at TikurAnbessa Specialized Hospital. Methods: This is unmatched case-control study design that tried to assess the association between non breast feeding practice and breast cancer. The study wasdone at TikurAnbessa Specialized Hospital radiotherapy center which is located in Addis Ababa, Ethiopia. Eligible cases were female breast cancer positive patient (pathology proven) and the controls were female breast cancer negative patient who were diagnosed for other non-reproductive system cancer, both cases and controls were either on chemotherapy or radiotherapy treatment service at TikurAnbessa Specialized Hospital. Theratio was 1:1 with 217female breast cancer patients and 217 females without breast cancers. The analyses were performed with Statistical Package for Social Sciences (SPSS) version 20. Odds ratio and 95% confidence interval done to quantify association between an exposure and disease. Result: , the odds of cases to report positive family history for breast cancer is about 2.6 times higher than the odds of controls to report the same. [AOR = 2.7(95%CI, 1.53, 4.93)]. The odds of cases to report menopausal status for breast cancer is about 2.4 times higher than the odds of controls to menopausal status to breast cancer. [AOR=2.4 (95% CI(1.2,4.7)]. The odds of cases that breastfed for breast cancer is about 50% lower than the odds of controls to report the same. [AOR = 0.05(95%CI, 0.34, 0.87)] Conclusion: The study document show that family history of breast cancer, women who never breast fed, and women in menopausal status were associated with Breast cancer risk. An inverse association between breastfeeding and breast cancer was found in this study among women on chemotherapy and radiotherapy in TikurAnbessa Hospital.

description: The feedback of the geometrical Berry phase, accumulated in an electron system, on the slow dynamics of classical degrees of freedom is governed by the Berry curvature. Here, we study local magnetic moments, modelled as classical spins, which are locally exchange coupled to the (spinful) Haldane model for a Chern insulator. In the emergent equations of motion for the slow classical-spin dynamics there is a an additional anomalous geometrical spin torque, which originates from the corresponding spin-Berry curvature. Due to the explicitly broken time-reversal symmetry, this is nonzero but usually small in a condensed-matter system. We develop the general theory and compute the spin-Berry curvature, mainly in the limit of weak exchange coupling, in various parameter regimes of the Haldane model, particularly close to a topological phase transition and for spins coupled to sites at the zigzag edge of the model in a ribbon geometry. The spatial structure of the spin-Berry curvature tensor, its symmetry properties, the distance dependence of its nonlocal elements and further properties are discussed in detail. For the case of two classical spins, the effect of the geometrical spin torque leads to an anomalous non-Hamiltonian spin dynamics. It is demonstrated that the magnitude of the spin-Berry curvature is decisively controlled by the size of the insulating gap, the system size and the strength of local exchange coupling.

description: In present work, spectrum of the $S$-wave fully-heavy tetraquark states $QQ\bar{Q}\bar{Q}$ ($Q=c,b$), i.e., $cc\bar{c}\bar{c}$, $bb\bar{b}\bar{b}$, $cc\bar{b}\bar{b}$/$bb\bar{c}\bar{c}$, $bc\bar{c}\bar{c}$/ $cc\bar{b}\bar{c}$, $bb\bar{c}\bar{b}$/$cb\bar{b}\bar{b}$, and $bc\bar{b}\bar{c}$ are systematically investigated within an nonrelativistic constituent quark model, in which the Instanton-induced and one-gluon-exchange interactions are taken into account as the residual spin-dependent hyperfine interaction. Our results show that the states with $cc\bar{c}\bar{c}$ and $bb\bar{b}\bar{b}$ components could be located around $ 6500$ MeV and $ 19200$ MeV, respectively. Based on our calculations, the new $X(6900)$ state observed by LHCb may be not a ground $cc\bar{c}\bar{c}$ tetraquark state, while it could be an orbitally or radially excited state of $cc\bar{c}\bar{c}$ system. On the other hand, the recently reported $X(6600)$ state by CMS and ATLAS can be explained as a ground $cc\bar{c}\bar{c}$ tetraquark state with spin-parity $J^{PC} =0^{++}$.

description: Background: skilled attendant for every pregnant woman during childbirth is the most critical intervention for improving maternal and child health. Ethiopia with maternal mortality ratio of 673 per 100,000 live births, the majority of births are delivered at home and the proportion of deliveries assisted by skilled attendant is very low. Objective: to assess utilization of skilled birth attendant at delivery, among mothers who gave birth the last one year prior to the survey in Mekelle town. Methodology: A cross-sectional household survey was conducted from Sep. 2006 to Oct.2006.Women who had delivered in Mekelle Town, within the last one-year prior to the survey obtained using proportional to population size of 10 "Tabias" through random walking were interviewed using structured and pre-tested questionnaire. Result: A total of 600 women were included in the study. 69% of the women utilize skilled birth attendant during delivery. Among the client who had institutional delivery their satisfaction to the time the health worker spent with them, cleanliness of instrument or equipment, the courtesy and respect offered by the provider, measures taken to assure their privacy and comfort , and professional competency and skill of the health worker during delivery was (95%). Births to women with primary education are two times more likely (OR=2.19and 95%CI=1.33-3.61), and births to women with secondary and above education are four times more likely (OR=3.90 and 95%CI=1.95-7.81) to utilize SDA as compared to illiterate women. Women who have secondary and above educated husband are three times more likely to utilize SDA than those illiterate (OR=3.10 and 95%CI=1.29-7.42). Women with first pregnancy OR=4.11 and 95%CI= 2.20, 7.68), women who have ANC visits OR=2.95 and (95%CI= 1.63, 5.37), women who know presence of pregnancy and delivery complication OR=3.40 and 95%CI 1.76.-6.57), women who obtained MCH information 2.27 and 95%CI viii 1.17-4.41), Those who have visit to health facility OR=2.95 and 95%CI=1.06-8.21), those who can get transportation OR=2.67 and 95%CI=1.59-4.49), and those their husband's prefer to use skilled delivery attendant during delivery OR=4.65 and 95%CI=2.37-9.13), were more likely to utilize skilled delivery attendant than those who are disadvantaged. Conclusions: increasing educational opportunities for both women and their husbands and particularly for girls, promotion of ANC follow-up with provision of MCH information particularly, the need for SDA at every childbirth, health workers particularly health extension workers should promote community awareness programs, home visit, and community-based delivery systems which focus the disadvantaged women and facilitation of supportive environment, such as supplies, equipment, establishing functioning system of referral and appropriate training of midwifes are recommended

description: Graphene is a quantum spin Hall insulator with a 45 $μ$eV wide non-trivial topological gap induced by the intrinsic spin-orbit coupling. Even though this zero-field spin splitting is weak, it makes graphene an attractive candidate for applications in quantum technologies, given the resulting long spin relaxation time. On the other side, the staggered sub-lattice potential, resulting from the coupling of graphene with its boron nitride substrate, compensates intrinsic spin-orbit coupling and decreases the non-trivial topological gap, which may lead to the phase transition into trivial band insulator state. In this work, we present extensive experimental studies of the zero-field splittings in monolayer and bilayer graphene in a temperature range 2K-12K by means of sub-Terahertz photoconductivity-based electron spin resonance technique. Surprisingly, we observe a decrease of the spin splittings with increasing temperature. We discuss the origin of this phenomenon by considering possible physical mechanisms likely to induce a temperature dependence of the spin-orbit coupling. These include the difference in the expansion coefficients between the graphene and the boron nitride substrate or the metal contacts, the electron-phonon interactions, and the presence of a magnetic order at low temperature. Our experimental observation expands knowledge about the non-trivial topological gap in graphene.

Pattern-induced anchoring transitions in nematic liquid crystals

description: In this paper we revisit the problem of a nematic liquid crystal in contact with patterned substrates. The substrate is modelled as a periodic array of parallel infinite grooves of well-defined cross section sculpted on a chemically homogeneous substrate which favors local homeotropic anchoring of the nematic. We consider three cases: a sawtooth, a crenellated and a sinusoidal substrate. We analyse this problem within the modified Frank-Oseen formalism. We argue that, for substrate periodicities much larger than the extrapolation length, the existence of different nematic textures with distinct far-field orientations, as well as the anchoring transitions between them, are associated with the presence of topological defects either on or close to the substrate. For the sawtooth and sinusoidal case, we observe a homeotropic to planar anchoring transition as the substrate roughness is increased. On the other hand, a homeotropic to oblique anchoring transition is observed for crenellated substrates. In this case, the anchoring phase diagram shows a complex dependence on the substrate roughness and substrate anchoring strength.
