In transition metal oxides, an insulating band gap is found when the energy scales related to ionic charge excitations dominate over electronic itinerancy. Here, the authors demonstrate strong electron-phonon interactions in Li2CuO2and their effect o

Multi-component spin-singlet superconductors with competing 0- and $\pi$-pairing couplings, as in $s_{++}$ and $s_{\pm}$ phases, are close to instabilities with a spontaneous breaking of time-reversal symmetry. We demonstrate that the modification of

Based on the phenomenological Ginzburg-Landau approach, we investigate phase solitonic states in a class of three-component superconductors for mesoscopic doubly-connected geometry (thin-walled cylinder) in external magnetic fields. Analysis of the G

We study an asymmetric $J_1$-$J_2$ zigzag ladder consisting of two different spin-$\frac{1}{2}$ antiferromagnetic (AFM; $J_2$, $\gamma J_2>0$) Heisenberg legs coupled by zigzag-shaped ferromagnetic (FM; $J_1

We report on a detailed neutron diffraction and $^{1}\mathrm{H}$-NMR study on the frustrated spin-1/2 chain material linarite, ${\mathrm{PbCuSO}}_{4}{(\mathrm{OH})}_{2}$, where competing ferromagnetic nearest-neighbor and antiferromagnetic next-neare

Frustrated one-dimensional (1D) magnets are known as ideal playgrounds for new exotic quantum phenomena to emerge. We consider an elementary frustrated 1D system: the spin-$\frac{1}{2}$ ferromagnetic ($J_1$) Heisenberg chain with next-nearest-neighbo

Within a Ginzburg-Landau formalism we establish analytically the necessary and sufficient conditions to realize a doubly degenerate superconducting ground state with broken time-reversal symmetry (BTRS) in a multi-band superconductor. Using these res

Motivated by the magnetic properties of the spin-chain compounds LiCuSbO$_4$$\equiv$LiSbCuO$_4$ and Rb$_2$Cu$_2$Mo$_3$O$_{12}$, we study the ground state of the Heisenberg chain with dimerized nearest-neighbor ferromagnetic (FM)($J_1, J_1^\prime0$) c

In various \(\mathrm{FeTe}_{1-x}\mathrm{Se}_{\mathrm{x}}\) (x=0–1), members of the 11-iron-pnictide superconductor family, the temperature dependent resistivity ρ can be scaled into a universal curve. It is found that the ρ(T) dependences can be

We present a short overview of different microscopic models for nonrelativistic and relativistic magnetoelectric coupling in 3d oxides with a particular emphasis on multiferroic properties observed in nonstoichiometric chain cuprates.
