  2. Book ; Online: Order-by-disorder charge density wave condensation at $\mathbf{\textit{q} =(\frac{1}{3},\frac{1}{3},\frac{1}{3})}$ in kagome metal ScV$_6$Sn$_6$

    Abstract The recent discovery of a charge density wave order at the wave vector $P$ $(\frac{1}{3},\frac{1}{3},\frac{1}{3})$ in the kagome metal ScV$_6$Sn$_6$ has created a mystery because subsequent theoretical and experimental studies show a dominant phonon instability instead at another wave vector $H$ $(\frac{1}{3},\frac{1}{3},\frac{1}{2})$. In this paper, I use first principles total energy calculations to map out the landscape of the structural distortions due to the unstable phonon modes at $H$, $L$ $(\frac{1}{2},0,\frac{1}{2})$, and $P$ present in this material. In agreement with previous results, I find that the distortions due to the $H$ instability cause the largest gain in energy relative to the parent structure, followed in order by the $L$ and $P$ instabilities. However, only two distinct structure occur due to this instability, which are separated by 6 meV/f.u. The instability at $L$ results in three distinct structures separated in energy by 5 meV/f.u. In contrast, six different distorted structures are stabilized due to the instability at $P$, and they all lie within 2 meV/f.u.\ of each other. Hence, despite a lower energy gain, the condensation at $P$ could be favorable due to a larger entropy gain associated with the fluctuations within a manifold with larger multiplicity via the order-by-disorder mechanism.

  3. Book ; Online: Possible structural quantum criticality tuned by rare-earth ion substitution in infinite-layer nickelates

    Abstract I show the infinite-layer rare-earth nickelates are near a structural quantum critical point by mapping the energetics of their structural instabilities using first priniciples calculations. I first confirm previous results that show a phonon instability in the $P4/mmm$ phase leading to the $I4/mcm$ structure for $R$NiO$_2$ with $R$ = Sm--Lu. I then study the non-spin-polarized phonon dispersions of the $I4/mcm$ phase and find that they exhibit rare-earth size dependent instabilities at the $X$ and $M$ points for materials with $R$ = Eu--Lu. Group-theoretical analysis was used to enumerate all the isotropy subroups due to these instablities, and the distorted structures corresponding to their order parameters were generated using the eigenvectors of the unstable phonons. These structures were then fully relaxed by minimizing both the atomic forces and lattice stresses. I was able to stabilize only five out of the twelve possible distortions. The $Pbcn$ isotropy subgroup with the $M_5^+(a,a)$ order parameter shows noticeable energy gain relative to other distortions for the compounds with late rare-earth ions. However, the order parameter of the lowest-energy phase switches first to $X_2^- (0,a) + M_5^+ (b,0)$ and then to $X_2^- (0,a)$ as the size of the rare-earth ion is progressively increased. Additionally, several distorted structures lie close in energy for the early members of this series. These features of the structural energetics persist even when antiferromagnetism is allowed. Such a competition between different order parameters that can be tuned by rare-earth ion substitution suggests that any structural transition that could arise from the phonon instabilities present in these materials can be suppressed to 0 K.

    Abstract The use of quality seed is a key driver for increasingthe agricultural productivity of Myanmar’s farmers. Theinherent characteristics of varieties and the quality of theseed determine to a large extent the yield potential andthe capacity of the crop to adapt to a changing climate.In recent years, improved varieties of a large number ofcrops have been developed or tested and released inMyanmar; however, not all of them have reached farmers.Access to good quality seed at an affordable price remainsa major issue for smallholder farmers in Myanmar.

    Abstract Maternal mortality rates are unacceptably high globally. Low- and middle-income countries (LMICs) face challenges of an inadequate anaesthesia workforce, under-resourced healthcare systems and sub-optimal access to labour and delivery care, all of which negatively impact maternal and neonatal outcomes. In order to effect the changes in surgical-obstetric-anaesthesia workforce numbers advocated by the Lancet Commission on Global Surgery to support the UN sustainable development goals, mass training and upskilling of both physician and non-physician anaesthetists is imperative. The implementation of outreach programmes and partnerships across organisations and countries has already been shown to improve the provision of safe care to mothers and their babies, and these efforts should be continued. Short subspecialty courses and simulation training are two cornerstones of modern obstetric anaesthesia training in poorly resourced environments. This review discusses the challenges to accessing quality maternal healthcare in LMICs and the use of education, outreach, partnership and research to protect the most vulnerable women from coming to harm in the peripartum period.

    Abstract I present first principles calculations of the phonon dispersions of TiSe$_2$ in the $P\overline{3}c1$ phase, which is the currently accepted low-temperature structure of this material. They show weak instabilities in the acoustic branches in the out-of-plane direction, suggesting that this phase may not be the true ground state. To find the lowest energy structure, I study the energetics of all possible distorted structures corresponding to the isotropy subgroups of $P\overline{3}m1$ for the $M_1^-$ and $L_1^-$ phonon instabilities present in this high-temperature phase at $q = (\frac{1}{2},0,0)$ and $(\frac{1}{2},0,\frac{1}{2})$, respectively. I was able to stabilize 10 different structures that are lower in energy relative to the parent $P\overline{3}m1$ phase, including two monoclinic structures more energetically stable than the $P\overline{3}c1$ phase. The lowest energy structure has the space group $C2$ with the order parameter $M_1^- (a,0,0) + L_1^- (0,b,b)$. This structure lacks inversion symmetry, and its primitive unit cell has 12 atoms.
