The nonsymmorphic Zr2Ir alloy is a possible topological semimetal candidate material and as such may be part of an exotic class of superconductors. Zr2Ir is a superconductor with a transition temperature of 7.4 K with critical fields of 19.6(3) mT and 3.79(3) T, as determined by heat capacity and magnetisation. Zero field muon spin relaxation measurements show that time-reversal symmetry is preserved in these materials. The specific heat and transverse field muon spin rotation measurements rule… Expand

Dirac surface states and nature of superconductivity in Noncentrosymmetric BiPd
TLDR
While the superconducting state of BiPd appears topologically trivial, consistent with Bardeen–Cooper–Schrieffer theory with an order parameter governed by a single isotropic s-wave gap, it is shown that the material exhibits Dirac-cone surface states with a helical spin polarization. Expand

Topological nodal-line fermions in spin-orbit metal PbTaSe2
TLDR
The detailed angle-resolved photoemission measurements, first-principles simulations and theoretical topological analysis illustrate the physical mechanism underlying the formation of the topological nodal-line states and associated surface states for the first time, thus paving the way towards exploring the exotic properties of the bottom-line fermions in condensed matter systems.

Topological quantum chemistry
TLDR
A complete electronic band theory is proposed, which builds on the conventional band theory of electrons, highlighting the link between the topology and local chemical bonding and can be used to predict many more topological insulators. Expand
Introduction to Superconductivity
We have seen how the conductivity of a metal is limited by collisions, which determine the electron mean free path. After a collision, an electron completely loses all memory of its quantum state asExpand
