Evidence of Charge-Phonon coupling in Van der Waals materials Ni1-xZnxPS3
Nashra Pistawala, Ankit Kumar, Devesh Negi +4
NiPS3 is a Van der Waals antiferromagnet that has been found to display spin-charge and spin-phonon coupling in its antiferromagnetically ordered state below TN = 155 K. Here, we s…
Optically induced symmetry breaking due to nonequilibrium steady state formation in charge density wave material 1T-TiSe2
Harshvardhan Jog, Luminita Harnagea, Dibyata Rout +4
The strongly correlated charge density wave (CDW) phase of 1T-TiSe is being extensively researched to verify the claims of a unique chiral order due to the presence of three eq…
Imaging the coherent propagation of collective modes in the excitonic insulator candidate TaNiSe at room temperature
Hope M. Bretscher, Paolo Andrich, Yuta Murakami +10
Excitonic insulators host a condensate of electron-hole pairs at equilibrium, giving rise to collective many-body effects. Although several materials have emerged as excitonic insu…
Pressure-induced suppression of charge density wave and emergence of Superconductivity in 1T-VSe2
S. Sahoo, U. Dutta, L. Harnagea +2
We report pressure evolution of charge density wave (CDW) order and emergence of superconductivity (SC) in 1T-VSe2 single crystal by studying resistance and magnetoresistance behav…
Magnetic and dielectric investigations of - FeWO
Soumendra Nath Panja, Jitender Kumar, Luminita Harnagea +2
The magnetic, thermodynamic and dielectric properties of the - FeWO system is reported. Crystallizing in the centrosymmetric space group, this particular pol…
Acoustic and optical phonon dynamics from femtosecond time-resolved optical spectroscopy of superconducting iron pnictide Ca(Fe_0.944Co_0.056)_2As_2
Sunil Kumar, L. Harnagea, S. Wurmehl +2
We report temperature evolution of coherently excited acoustic and optical phonon dynamics in superconducting iron pnictide single crystal Ca(Fe_0.944Co_0.056)_2As_2 across the spi…
