Evidence of electron correlation induced kink in Dirac bands in a non-symmorphic Kondo lattice system, CeAgSb2
Sawani Datta, Khadiza Ali, Rahul Verma +4
We study the behavior of Dirac fermions in the presence of electron correlation in a nonsymmorphic Kondo lattice system, CeAgSb2 employing high-resolution angle-resolved photoemiss…
Ultrafast Carrier Relaxation and Second Harmonic Generation in a Higher-Fold Weyl Fermionic System PtAl
Vikas Saini, Ajinkya Punjal, Utkarsh Kumar Pandey +10
In topological materials, shielding of bulk and surface states by crystalline symmetries has provided hitherto unknown access to electronic states in condensed matter physics. Inte…
Broken time-reversal symmetry in cubic skutterudite-like superconductor YRuGe
A. Kataria, J. A. T. Verezhak, O. Prakash +6
The microscopic properties of superconducting cubic skutterudite-like material YRuGe are investigated using muon spin relaxation and rotation (SR) measurements. Z…
Annealing-induced long-range charge density wave order in magnetic kagome FeGe: fluctuations and disordered structure
Chenfei Shi, Yi Liu, Bishal Baran Maity +18
Charge density wave (CDW) in kagome materials with the geometric frustration is able to carry unconventional characteristics. Recently, a CDW has been observed below the antiferrom…
Inelastic neutron scattering investigation of the crystal field excitations of NdCo
F. de Almeida Passos, G. J. Nilsen, C. E. Patrick +6
We present an inelastic neutron scattering study of the crystal electric field levels in the intermetallic ferrimagnets RECo (RE = Nd and Y). In NdCo, measurements at $…
Complexity in the hybridization physics revealed by depth-resolved photoemission spectroscopy of single crystalline novel Kondo lattice systems, CeCuX (X = As/Sb)
Sawani Datta, Ram Prakash Pandeya, Arka Bikash Dey +6
We investigate the electronic structure of a novel Kondo lattice system CeCuX2 (X = As/Sb) employing high resolution depth-resolved photoemission spectroscopy of high quality singl…
Non-Conventional Critical Behavior and Q-dependent Electron-Phonon Coupling Induced Phonon Softening in the CDW Superconductor LaPt2Si2
Elisabetta Nocerino, Uwe Stuhr, Irene San Lorenzo +12
This paper reports the first experimental observation of phonons and their softening on single crystalline LaPtSi via inelastic neutron scattering. From the temperature dep…
Evidence of The Anomalous Fluctuating Magnetic State by Pressure Driven 4f Valence Change in EuNiGe
K. Chen, C. Luo, Y. Zhao F. Baudelet +5
In rare-earth compounds with valence fluctuation, the proximity of the 4f level to the Fermi energy leads to instabilities of the charge configuration and the magnetic moment. Here…
Coexistence of phononic Weyl, nodal line, and threefold excitations in chalcopyrite CdGeAs and associated thermoelectric properties
Vikas Saini, Bikash Patra, Bahadur Singh +1
Realization of topologically protected quantum states leads to unprecedented opportunities for fundamental science and device applications. Here, we demonstrate the coexistence of…
