After four years in the making Muhammad Ahmed has submitted his PhD thesis entitled "Conﬁned magnon transport in low-dimensional ferromagnetic structures". In his thesis Muhammad has extensively investigated spin chains and 2D-arrays in the Heisenberg model and has developed methods to make use of spin exitations / magnons for classical and quantum information transport. He found ways to confine, accelerate and control the width of magnons in spin arrays as well as calculating a scheme to create and couple magnon guides and create a magnonic interferometer. During his PhD Muhammad also got married and his first child was born, two amazing life events which are certainly not made easier by PhD work. So congratulations on all your achievements in the last four years, Muhammad!
