Enhancement of magnetization plateaus in low dimensional spin systems
Alexandros Metavitsiadis, Christina Psaroudaki, Wolfram Brenig
We study the low-energy properties and, in particular, the magnetization process of a spin-1/2 Heisenberg sawtooth and frustrated chain (also known as zig-zag ladder) wit…

Spin liquid fingerprints in the thermal transport of a Kitaev-Heisenberg ladder
Alexandros Metavitsiadis, Christina Psaroudaki, Wolfram Brenig
We identify fingerprints of a proximate quantum spin-liquid (QSL), observable by finite-temperature dynamical thermal transport within a minimal version of the idealized Kitaev mod…
