A new theoretical concept of the quantum mechanical processes in spin filter for the separation ofmetastable hydrogen atoms in individual hyperfine substates enables a number of new applications.For example, it is now possible to build a new generation of Lamb-shift polarimeter that canseparate not only 𝛼 but also the 𝛽 substates with $𝑚_𝐽 = −1/2$. This opens up completely newpossibilities for the search of hydrogen atoms in forbidden substates after the bound beta decayof the neutron. [...]

The manipulation of magnetization via magnetic torques is one of the most important phenomena in spintronics. In thin films, conventionally, a charge current flowing in a heavy metal is used to generate transverse spin currents and to exert torques on the magnetization of an adjacent ferromagnetic thin film layer. [...]

We present a systematic study of scalar potential induced topological transition in massive Dirac fermions. We show how a distribution of scalar potential can manipulate the signature of the gap or the mass, as well as the dispersion leading to a band inversion. [...]

Efficient manipulation of magnetization by electrical current is a key aim in spintronics. The state- of-the-art theories and experiments in spintronics show that harnessing non-equilibrium orbital angular momentum can significantly enhance the efficiency due to novel torques. [...]

Perpendicular magnetic anisotropy thin film systems are well known for their periodic magnetic stripe domain structures. In this study, we focus on investigating the behavior of [Co(3.0 nm)/Pt(0.6 nm)]X multilayers within the transitional regime from preferred in-plane to out-of-plane magnetization orientation. [...]
