Emergent Random Spin Singlets in Disordered Spin-1/2 perovskite BaCuTaO
Sagar Mahapatra, Francesco De Angelis, Dibyata Rout +8
We investigate the disordered perovskite BaCuTaO, where Cu (spin-1/2) and Ta randomly occupy a pseudo-cubic lattice. Synchrotron X-ray diffraction and X-ray abs…

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…

Dynamics of electron-electron correlated to electron-phonon coupled phase progression in trilayer nickelate La4Ni3O10
Sonia Deswal, Deepu Kumar, Dibyata Rout +2
Trilayer nickelates are a rich class of materials exhibiting diverse correlated phenomena, including superconductivity, density wave transitions, non-Fermi liquid behavior along wi…
