Magnetic-monopole-induced polarons in atomic superlattices

Magnetic monopoles have been realized as emergent quasiparticles in both condensed matter and ultracold atomic platforms, with growing interest the coupling effects between monopole different magnetic quasiparticles. In this work, interaction magnons are investigated for an pseudospin chain. We reveal that can excite a virtual magnon cloud paramagnetic chain, thereby giving rise to unconventional type of polaron, monopole-cored polaron (MCP). The MCP is composed impurity core excitation dressing cloud. facilitates Dirac string impacts hopping. This induces antitrapping effect MCP, which refers fact enhances mobility contrast self-trapping common polarons. Moreover, heterogeneous bipolarons shown exist under simultaneous doping north south monopole. bipolaron possesses inner degree freedom two identical impurities. Our investigation sheds light on understanding how engineer property polaron.
