Visualization of Tunable Electronic Structure of Monolayer TaIrTe
Sandy Adhitia Ekahana, Aalok Tiwari, Souvik Sasmal +16
Monolayer TaIrTe is an ideal platform to explore the tunability of band topology where charge doping converts the quantum spin Hall insulator (QSHI) state into a dual QSHI stat…
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…
Analysis of the unconventional chiral fermions in a non-centrosymmetric chiral crystal
Vikas Saini, Souvik Sasmal, Ruta Kulkarni +2
Symmetry-protected non-trivial states in chiral topological materials hold immense potential for fundamental science and technological advances. Here, we report electrical transpor…
Antiferromagnetism and large magnetoresistance in GdBi single crystal
Gourav Dwari, Souvik Sasmal, Bishal Maity +3
Single crystal of the binary equi-atomic compound GdBi crystallizing in the rock salt type cubic crystal structure with the space group has been grown by flux method.…
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…
Valence fluctuation in CeReSi and Ising-type magnetic ordering in PrReSi single crystals
Suman Sanki, Vikash Sharma, Souvik Sasmal +5
Single crystals of and have been grown by Czochralski method in a tetra-arc furnace. Powder x-ray diffraction confirmed that these compoun…
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…
Linear unsaturated magnetoresistance in YSi single crystal
Vikas Saini, Souvik Sasmal, Ruta Kulkarni +1
Linear magnetoresistance is a phenomenon that has been observed in a few topological compounds that originate from classical and quantum phenomena. Here, we performed electrical tr…
Fermi surface studies of a non-trivial topological compound YSi
Vikas Saini, Souvik Sasmal, Ruta Kulkarni +2
The Fermi surface properties of a nontrivial system YSi is investigated by de Haas-van Alphen (dHvA) oscillation measurements combined with the first-principle calculations. Three…
