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…
Effect of pressure, doping and magnetism on electronic structure and phonon dispersion of FeSe
Abyay Ghosh, Piotr Chudzinski, Myrta Grüning
We present a Density Functional Theory (DFT) based first-principles study on iron chalcogenides superconductor FeSe, systematically investigating pressure and doping induced modifi…
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…
