Localised quasiclassical states in asymptotic theory of ion-atom interactions

The interest to the study of localised states in atomic physics is, on the one hand, evoked by the fact, that in the numerous cases their analysis can be carried out analytically. Such method belongs to not much approaches, which allow investigating the system with nonfactorised variables without the use of perturbation theory or cumbersome numerical methods. On the other hand, the aforementioned states often…

One-Way Transfer of Magnetic Fields

Researchers have created a material that acts as a magnetic diode, transferring magnetism from one object to another but not the other way around. An electric current flowing through a coil of copper wire induces a magnetic field in the coil. This magnetic field can then transfer to a nearby magnetic object, such as a second coil of wire. The laws of electromagnetism, and experimental…
