Remarks about the Zeeman splitting in quantum dots and single atom transistors

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.
