Magnon dynamics in quantum magnetism have long sparked interest in condensed matter physics. Since Bethe's prediction nearly a century ago, multimagnon bound states have presented significant potential for both fundamental insights and technological

We consider nonreciprocal supercurrent effects in Josephson junctions based on multiband superconductors with a pairing structure that can break time-reversal symmetry. We demonstrate that a nonreciprocal supercurrent can be generally achieved by the

Despite decades of intensive experimental and theoretical efforts, the physics of cuprate high-temperature superconductors in general, and, in particular, their normal state, is still under debate. Here, we report our investigation of low-energy char

It is well-established that multicomponent superconductors can host different nonstandard phenomena such as broken-time reversal symmetry (BTRS) states, exotic Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) phases, the fractional Josephson effect as well as

Die schnelle Verfügbarkeit von Ersatzteilen hat einen maßgeblichen – wenn auch indirekten – Anteil an der Wertschöpfung produzierender Unternehmen. Kommt es zu einem ungeplanten Stillstand der Produktionsanlagen, kann dies schnell zu Kosten in

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; $J_1<0$) inter-leg interaction. On the basis of

This thesis examines a cultural revolution that took place in the Icelandic artistic landscape during the medieval period. Within just one generation (c. 1350–1400), the house of canons regular of Helgafell rose to become the most important centre
