Altermagnetic polarons: the fate of alter magnetic band splittings at strong coupling
Maria Daghofer, Krzysztof Wohlfeld, Jeroen van den Brink
While a spin-dependent band splitting is one of the characteristic features of altermagnets, the conventional band picture itself breaks down in the many altermagnets that are corr…

Nature of Spinons in 1D Spin Chains
Teresa Kulka, Milosz Panfil, Mona Berciu +1
We provide an intuitive understanding of the collective low-energy spin excitation of the one-dimensional spin-1/2 antiferromagnetic Heisenberg chain, known as the spinon. To this…
