Interplay of spin-phonon coupling in FeSe with pressure and isoelectronic (S/Te) substitution
Abyay Ghosh, Piotr Chudzinski, Myrta Grüning
In several studies, magnetism has been shown to strongly influence the properties of the iron chalcogenide compound \ce{FeSe}. In our previous work [Phys. Rev. Res. 6(4), 043154 (2…

Tomonaga-Luttinger Liquid parameters in Multi-wall Nanotubes
Naira Grigoryan, Piotr Chudzinski
Tomonaga-Luttinger liquid (TLL) theory is a canonical formalism used to describe one-dimensional (1D) metals, where the low energy physics is determined by collective bosonic excit…

A first-principles study and mesoscopic modeling of two-dimensional spin and orbital fluctuations in FeSe
Abyay Ghosh, Piotr Chudzinski, Myrta Grüning
We calculated the structural, electronic and magnetic properties of FeSe within density-functional theory at the generalized gradient approximation level. First, we studied how the…
