Electric-field driven flat bands in the distorted sawtooth chain via the Katsura-Nagaosa-Balatsky mechanism
Vadim Ohanyan, Lusik Amiraghyan, Michael Sekania +1
We investigate flat magnonic bands in a generalized sawtooth-chain model in which three sets of exchange parameters (symmetric Heisenberg exchange, axial Ising anisotropy, and anti…

On flat bands in the -- XXZ sawtooth chain
Vadim Ohanyan, Johannes Richter, Michael Sekania +3
We consider a generalization of the XXZ model on the sawtooth spin chain with Dzyaloshinskii-Moriya interactions in which all exchange constants (symmetric, antisymmetric, and axia…

Compressed Sensing of Compton Profiles for Fermi Surface Reconstruction: Concept and Implementation
J. Otsuki, K. Yoshimi, Y. Nakanishi-Ohno +3
Compton scattering is a well-established technique that can provide detailed information about electronic states in solids. Making use of the principle of tomography, it is possibl…
