WebApr 4, 2024 · Quantum simulation of an exotic quantum critical point in a two-site charge Kondo circuit. The quantum critical behaviour of a two-impurity Kondo model variant is observed in a system of hybrid ... WebFeb 1, 2024 · We have analyzed the edge states in a ferromagnetic honeycomb lattice with armchair edges and an external on-site potential at the outermost sites. In contrast with graphene, our system without external on-site potential reveals two edge states.

WebOct 21, 2024 · also named topological magnon insulator [6], are char-acterized by nonzero Chern numbers and topologically protected magnon edge states, similar to electronic topo-logical insulators [7,8]. Quantum transport based on topological magnon edge states are highly promising to achieve dissipationless transport without ohmic loss [9,10,12{15]. WebSep 7, 2024 · We present the bulk-edge correspondence for the magnons in a honeycomb lattice with an armchair or a zigzag boundary. Furthermore, we find Tamm-like edge states due to the intrinsic on-site interactions along the boundary sites. Our results may have significant implications to magnon transport properties in the 2D magnets at low … sièges bastiat hagetmau

Webmagnon edge states. These edge states give rise to local surface magnetization which we probe for kerr rotation. This is the first documented optical detection of magnon spin nernst. Due to structural instabilities in the sample geometry a new sample stage was required to obtain higher confidence results. A new stage was designed and WebMay 9, 2024 · We find topologically protected chiral magnonic edge states over a wide range of magnetic fields and Dzyaloshinskii-Moriya interaction values.
