Evidence of electron correlation and unusual spectral evolution in an exotic superconductor, PdTe
Ram Prakash Pandeya, Arindam Pramanik, Pramita Mishra +3
We study the electronic structure of an exotic superconductor, PdTe employing depth-resolved high resolution photoemission spectroscopy and density functional theory. The valence b…
Uncovering the nature of transient and metastable non-equilibrium phases in 1-TaS
Tanusree Saha, Arindam Pramanik, Barbara Ressel +7
Complex systems are characterized by strong coupling between different microscopic degrees of freedom. Photoexcitation of such materials can drive them into new transient and long-…
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^…
Anomalies in the electronic structure of a 5 transition metal oxide, IrO
Swapnil Patil, Aniket Maiti, Surajit Dutta +7
Ir-based materials have drawn much attention due to the observation of insulating phase believed to be driven by spin-orbit coupling while Ir 5 states are expected to be weakly…
