Abstract

Discovery of quantized electric conductance by the group of van Wees in 1988 was a major breakthrough in physics. Later, the group of Schwab has proven the existence of quantized thermal conductance. Advancing one step further, we present that quantized entropy current can be interpreted and it ease the description of a transferred quantized energy package. This might yield a universal transport behavior of the microscopic world. During the transfer of a single energy quantum, $h \nu$ between two neighboring domains the minimum entropy increment is calculated. Furthermore, the possible existence of the minimum entropy production can be formulated.
