Odd-parity electronic order near the semiconductor limit
Jack Tregidga, Dibyata Rout, Johannes Hielscher +3
Identifying materials platforms in which dilute carriers experience strong Coulomb interactions is a central challenge in the search for interaction-driven quantum phases. In such…
Raman scattering spectroscopic observation of a ferroelastic crossover in bond-frustrated PrCdP
Jackson Davis, Jesse Liebman, Dibyata Rout +3
2D magnetism in triangular lattices has already shown potential for hosting exotic magnetic states. Control of these magnetic states, both in terms of magnetic properties and in te…
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…
Interleaved bond frustration in a triangular lattice antiferromagnet
S. J. Gomez Alvarado, J. R. Chamorro, D. Rout +14
Frustration of long-range order via lattice geometries serves to amplify fluctuations of the order parameter and generate unconventional ground states that are highly sensitive to…
Hidden frustration in the triangular-lattice antiferromagnet NdCd3P3
Juan R. Chamorro, Steven J. Gomez Alvarado, Dibyata Rout +6
We report a study of the magnetic ground state and crystal electric field (CEF) scheme in the triangular-lattice antiferromagnet NdCdP. Combined neutron scattering, magneti…
