Anisotropic fully-gapped superconductivity in quasi-one-dimensional LiMoO
M. J. Grant, T. M. Huijbregts, R. Nicholls +4
Superconductivity in quasi-one-dimensional LiMoO emerges from an exotic, non-metallic normal state that exhibits signatures of Tomonaga-Luttinger liquid behavior…
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…
Generalized incommensurability: the role of anomalously strong spin-orbit coupling for the spin ordering in a quasi-2D system, FeSe
Piotr Chudzinski, Abyay Ghosh, Myrta Gruening
We study 2D spin and orbital systems, in a classical limit, in a regime where their coupling is so strong that orbital fluctuations are able to change sign of spin-exchange. Our ai…
Exact correlation functions at finite temperatures in Tomonaga-Luttinger liquid with an open end
Naira Grigoryan, Piotr Chudzinski
The paradigmatic state of a 1D collective metal, the Tomonaga-Luttinger liquid (TLL), offers us an exact analytic solution for a strongly interacting quantum system not only for in…
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…
Why it is so hard to detect Luttinger liquids in ARPES?
P. Chudzinski
The problem of photoemission from a quasi-1D material is studied. We identify two issues that play a key role in the detection of gapless Tomonaga-Luttinger liquid (TLL) phase. Fir…
