The Gross-Neveu model with chemical potential is investigated as a lowenergy effective theory of polyacetylene. In particular, we focus on the abrupt change in the features of electric conductivity such as sharp rise in the Pauli paramagnetism at dopant concentration of about 6%. We will try to explain it by the finite density phase transition in the Gross-Neveu model. The thermodynamic Bethe a...

Single-wall carbon nanotubes can be doped, or intercalated, with electron donors or acceptors, similar to graphite and some conjugated polymers. The resulting materials show many of the same features: enhanced electrical conductivity, conduction electron paramagnetism, partial or complete reversibility, and cyclability. Reactions may be carried out in vapor or liquid phase, or electrochemically...

Paramagnetism in solid-state materials has long been considered an additional challenge for structural investigations by using nuclear magnetic resonance spectroscopy (ssNMR). The strong interactions between unpaired electrons and the surrounding atomic nuclei, on one hand, are complex to describe, other hand can cause fast decaying signals extremely broad resonances. However, significant progr...

Abstract Dynamic manipulation of magnetism in topological materials is demonstrated here via a Floquet engineering approach using circularly polarized light. Increasing the strength laser field, besides expected phase transition (PT), magnetically doped insulator thin film also undergoes magnetic PT from ferromagnetism to paramagnetism, whose critical behavior strongly depends on quantum quench...

Unlike other Plasmodium species, P. falciparum can be cultured in the lab, which facilitates its study (1). While the parasitemia achieved can reach the ≈40% limit, the investigator usually keeps the percentage at around 10%. In many cases it is necessary to isolate the parasite-containing red blood cells (RBCs) from the uninfected ones, to enrich the culture and proceed with a given experiment...

We describe a study of the magneto-optical properties Ag+-doped CdSe colloidal nanoplatelets (NPLs) that were grown using novel doping technique. In this work, we used magnetic circularly polarized luminescence and circular dichroism spectroscopy to light-induced magnetism for first time in 2D solution-processed structures doped with nominally nonmagnetic Ag+ impurities. The excitonic polarizat...
