Weak antilocalization and Shubnikov-de Haas oscillations in CaCuSb single crystal
Souvik Sasmal, Vikas Saini, Nicolas Bruyant +5
Quantum oscillations in both linear and Hall resistivities and weak antilocalization (WAL) are barely observed in bulk single crystals. Here we report the transport properties of a…
Nanoscale devices with superconducting electrodes to locally channel current in 3D Weyl semimetals
Biswajit Datta, Jaykumar Vaidya, Subhamoy Ghatak +5
We report on the fabrication of nano-devices on the \hkl[-1 0 1] surface of a Weyl semimetal, a macroscopic crystal of TaAs, and low-temperature transport measurements. We can impl…
Emergence of well screened states in a superconducting material of the CaFeAs family
Ram Prakash Pandeya, Anup Pradhan Sakhya, Sawani Datta +10
Coupling among conduction electrons (e.g. Zhang-Rice singlet) are often manifested in the core level spectra of exotic materials such as cuprate superconductors, manganites, etc. T…
Behavior of gapped and ungapped Dirac cones in an antiferromagnetic topological metal, SmBi
Anup Pradhan Sakhya, Shiv Kumar, Arindam Pramanik +10
We studied the behavior of nontrivial Dirac fermion states in an antiferromagnetic metal SmBi using angle-resolved photoemission spectroscopy (ARPES). The experimental results exhi…
Anomalies in the temperature evolution of the Dirac states in a topological crystalline insulator SnTe
Ayanesh Maiti, Ram Prakash Pandeya, Bahadur Singh +3
Discovery of topologically protected surface states, believed to be immune to weak disorder and thermal effects, opened up a new avenue to reveal exotic fundamental science and adv…
