Remarks about the Zeeman splitting in quantum dots and single atom transistors
Abstract
An empirical formula is proposed to calculate the Kondo temperature in quantum point contacts from the Zeeman splitting. A similar formula was used in the point-contact spectroscopy (PCS) method to obtain from the Zeeman splitting of the Kondo peak in the characteristics of the classical Kondo alloys AuFe and CuMn [1]. Using this formula, it is possible to find the Kondo temperature taking into account the temperature of the experiment and Lande factor of the compounds.
