A magnetic bimeron is a pair of two merons and can be understood as the in-plane
magnetized version of a skyrmion. Here we theoretically predict the existence of single …

A detailed study of reduced-basis tight-binding models of electrons in semiconducting
quantum wells is presented. The focus is on systems with degenerate valleys, such as …

We present an overview of our recent theoretical studies on the quantum phenomena of the
spin-1 Bose-Einstein condensates, including the phase diagram, soliton solutions and the …

We consider bilayer graphene in the presence of spin–orbit coupling, in order to assess its
behavior as a topological insulator. The first Chern number n for the energy bands of single …

The nonequilibrium dynamics of a rapidly quenched spin-1 Bose gas with spin-orbit
coupling is studied. By solving the stochastic projected Gross-Pitaevskii equation, we show …

As a consequence of the approximate spin-valley symmetry in graphene, the ground state of
electrons in graphene at charge neutrality is a particular SU (4) quantum Hall ferromagnet to …

In strongly correlated quantum Hall ferromagnets with noninteger filling factors between ν= 1
and ν= 3/2, evidence of offbeat spin textures is obtained. The platforms for the study are two …

We model quantum Hall skyrmions in graphene monolayer at quarter filling by a theory of
CP 3 fields and study the energy minimizing skyrmions in the presence of valley pseudospin …

We explore different Skyrmion types in the lowest Landau level of graphene at a filling factor
ν=±1. In addition to the formation of spin and valley pseudospin Skyrmions, we show that …

We introduce a model to study magnon scattering in skyrmion crystals, sandwiched between
ferromagnets, which act as the source of magnons. Thanks to recent experimental …
