Interplay of phonons, intertwined density waves, and induced spin density wave in trilayer nickelates Pr4-xLaxNi3O10
Sonia Deswal, Dibyata Rout, Nirmalya Jana +3
Lattice degrees of freedom (DoF) play a central role in correlated electron systems, strongly influencing the dynamics of the underlying charge carriers and spin excitations. In ni…
Atomistic origin of low thermal conductivity in quaternary chalcogenides Cu(Cd, Zn)InTe
Nirmalya Jana, Amit Agarwal, Koushik Pal
Crystalline semiconductors with intrinsically low lattice thermal conductivity () are vital for device applications such as barrier coatings and thermoelectrics. Quate…
Origin of Glass-like Thermal Conductivity in Crystalline TlAgTe
Shantanu Semwal, Yi Xia, Chris Wolverton +1
Ordered crystalline compounds exhibiting ultralow and glass-like thermal conductivity are both fundamentally and technologically important, where phonon quasi-particles dominate th…
Antipolar and short and long-range magnetic ordering in quasi-two-dimensional AgCrP2S6
Chaitanya B. Auti, Atul G. Chakkar, Shantanu Semwal +6
Within the Landau theoretical framework, the decreased entropy with decreasing the temperature is accompanied by the symmetry breaking and hence a corresponding phase transition. T…
Raman signature of multiple phase transitions and quasi-particle excitations in putative Kitaev spin liquid candidate Na2Co2TeO6
Atul G. Chakkar, Chaitanya B. Auti, Deepu Kumar +3
Two-dimensional cobalt-based honeycomb oxide Na2Co2TeO6 is an important candidate for the realization of Kitaev physics and may provide future platform for the quantum computation…
