Non-centrosymmetric, transverse structural modulation in SrAl4, and elucidation of its origin in the BaAl4 family of compounds
Sitaram Ramakrishnan, Surya Rohith Kotla, Hanqi Pi +13
At ambient conditions SrAl4 adopts the BaAl4 structure type with space group I4/mmm. It undergoes a charge-density-wave (CDW) transition at TCDW = 243 K, followed by a structural t…
Enhancement of density of states and suppression of superconductivity in site-disordered topological metal LaPtSi
Sitaram Ramakrishnan, Tatsuya Yamakawa, Ryohei Oishi +5
Single crystals of non-centrosymmetric -wave superconductor LaPtSi have been grown by the Czochralski (Cz) technique, whose crystal structure is described by t…
A Trivial Geometrical Phase of an Electron Wavefunction in a Direct Band Gap Semiconductor CdGeAs
Vikas Saini, Souvik Sasmal, Vikash Sharma +5
Chalcopyrite compounds are extensively explored for their exotic topological phases and associated phenomena in a variety of experiments. Here, we discuss the electrical transport…
Realization of Z Topological Metal in Single-Crystalline Nickel Deficient NiVSe
Sitaram Ramakrishnan, Shidaling Matteppanavar, Andreas Schonleber +6
Temperature-dependent electronic and magnetic properties are reported for a Z2 topological metal single-crystalline nickel-deficient NiVSe. It is found to crystallize in th…
Superconductivity in single crystals of a quasi-one dimensional infinite chain cuprate SrCaCuO at 90 K
Neeraj K. Rajak, Dumpala Tirumalarao, Gourav Vaid +13
Although there is no complete theory of high temperature superconductivity, the importance of CuO planes in cuprate superconductors is confirmed from both theory and experiment…
Fragile electronic superconductivity in Bi Single crystal
Anil Kumar, Rajendra Loke, Arindam Pramanik +6
It was presumed that semimetal Bismuth (Bi) would not show superconductivity (SC) even at ultra-low temperatures (10 mK) due to its very low carrier density ($\approx 3\times10^…
