Synthesis of possible room temperature superconductor LK-99:PbCu(PO)O
Kapil Kumar, N. K. Karn, V. P. S. Awana
The quest for room-temperature superconductors has been teasing scientists and physicists, since its inception in 1911 itself. Several assertions have already been made about room…
Normal state magneto transport properties of FeSeTe superconductor: The role of topological surface states
N. K. Karn, M. M. Sharma, V. P. S. Awana
Doped Iron Chalcogenide (FeCh) superconductors are extensively studied in the context of topological superconductivity. However, the evidence of topological surface states in elect…
Weak Antilocalization and topological edge states in PdSn
N. K. Karn, M. M. Sharma, V. P. S. Awana
Here we report, the successful synthesis of single crystals of topological semimetal (TSM) candidate, PdSn using the self-grown route. The synthesized crystal is well character…
Band topology and non-trivial surface States in type-II Dirac semi-metal (Ni, Pd)Te2
NK Karn, VPS Awana
The semi-metals having electrons near the Fermi level follow the relativistic equation of motion, and show Dirac or Weyl-type behavior. Their orbital resolved electronic bands anal…
Topology of quadrupolar Berry phase of a Qutrit
Rajeev Singh, Navneet Kumar Karn, Rahul Bhowmick +1
We examine Berry phase pertaining to purely quadrupolar state () of a spin- system. Using the Majorana stellar representation of these states,…
