The spin-polarized calculations in generalized gradient approximation density–functional theory (GGA–DFT) have been used to show how the existence of second metals can modify the atomic hydrogen adsorption on Au (100), Cu (100), and Pt (100) surfaces. The computed adsorption energies for the atomic hydrogen adsorbed at the surface coverage of 0.125 ML (monolayer) for the monometallic Au (100), ...

The precise control of direct current (dc) magnetic fields is crucial in a wide range experimental platforms, from ultracold quantum gases and nuclear resonance to precision measurements. In each these cases, the Zeeman effect causes states shift energy as function field. development low-noise sources essential because electromagnets are preferred tool dynamically Here, we describe an ultra-low...
