Orbital entangled antiferromagnetoc order and spin-orbit-distortion exciton in
Shubhajyoti Mohapatra, Dheeraj Kumar Singh, Rajyavardhan Ray +2
With electron filling in the compound, the octahedrally coordinated orbitals are strongly active due to tetragonal distortion induced crystal fiel…
Simulation of Nuclear Recoils due to Supernova Neutrino-induced Neutrons in Liquid Xenon Detectors
Sayan Ghosh, Abhijit Bandyopadhyay, Pijushpani Bhattacharjee +3
Neutrinos from supernova (SN) bursts can give rise to detectable number of nuclear recoil (NR) events through the coherent elastic neutrino-nucleus scattering (CENS) process in…
Dynamical density and spin response of Fermi arcs and their consequences for Weyl semimetals
Sayandip Ghosh, Carsten Timm
Weyl semimetals exhibit exotic Fermi-arc surface states, which strongly affect their electromagnetic properties. We derive analytical expressions for all components of the composit…
Charge-spin response and collective excitations in Weyl semimetals
Sayandip Ghosh, Carsten Timm
Weyl semimetals are characterized by unconventional electromagnetic response. We present analytical expressions for all components of the frequency- and wave-vector-dependent charg…
Magnetic excitations in iron pnictides
Nimisha Raghuvanshi, Sayandip Ghosh, Rajyavardhan Ray +2
Spin wave dispersion and damping are investigated in the metallic SDW state of different itinerant electron models including a small interlayer hopping. Magnetic excitations in iro…
