Magnetocaloric effect in spin-1/2 $XX$ chains with three-spin interactions

Myroslava Topilko, Taras Krokhmalskii, Oleg Derzhko +1

We consider the exactly solvable spin-1/2 $XX$ chain with the three-spin interactions of the $XZX+YZY$ and $XZY-YZX$ types in an external (transverse) magnetic field. We calculate…
