The most well-known example of an ordered quantum state—superconductivity—is caused
by the formation and condensation of pairs of electrons. Fundamentally, what distinguishes …

Multicomponent superconductivity is realized in multiband superconductors when an
interband pairing interaction is considerably weaker than the intraband interactions. There is …

This article reviews theoretical and experimental work on the novel physics in multiband
superconductors. Multiband superconductors are characterized by multiple superconducting …

Discussing changes over the last two decades, this book represents an up-to-date treatment
of superfluidity. It covers new superfluid materials such as high-temperature and …

We show that continuous and spin-lattice models of chiral ferro-and antiferromagnets
provide the existence of an infinite number of stable soliton solutions of any integer …

Magnetic skyrmions are nanoscale topological textures that have been recently observed in
different families of quantum magnets. These objects are called CP1 skyrmions because …

We study CP 2 skyrmion crystals in the ferromagnetic SU (3) Heisenberg model with a
generalization of the Dzyaloshinskii-Moriya interaction and the Zeeman term. The model …

Arguments were recently advanced that hole-doped Ba 1− x K x Fe 2 As 2 exhibits the s+ is
state at certain doping. Spontaneous breaking of time-reversal symmetry in the s+ is state …

A procedure to derive the Ginzburg-Landau (GL) theory from the multiband BCS
Hamiltonian is developed in a general case with an arbitrary number of bands and arbitrary …

In this work we explore the relationship between two ideas recently introduced in the
literature. The first one deals with a quantity related to the informational contents of solutions …
