We study the manipulation of Majorana zero modes in a thin disk made from $p$-wave superconductor order to understand their use as building block for topological quantum computers. analyze second-order corner that arise when an in-plane magnetic field is applied, and calculate dynamical evolution rotating field, with special emphasis on non-adiabatic effects. characterize phase transition betwe...

A novel extraction approach was developed based on rotating-disk sorptive extraction (RDSE). In this approach the rotating-disk extraction device consists of a Teflon disk, with a cavity that is loaded with a commercial sorbent phase selected according to the polarity of the analyte. To avoid leakage of the sorbent, the cavity is covered with a fiberglass filter and sealed with a Teflon ring. T...

Context. One of the most outstanding problems related to numerical models of galaxy formation is the so-called " angular momentum catastrophe " , i.e., the inability to explain theoretically the high angular momentum observed in local disk galaxies. Aims. We study the evolution of the angular momentum from z∼0.6 to z=0 to further our understanding of the mechanisms responsible for the large ang...
