Negative-spin quasiparticles in quantum Hall effect

Abstract

The spin of the electron is a positive number, s =1/2. It is found that there is a negative-spin quasiparticle with negative spin, s =−1/2. This means that in a magnetic field the ±1/2 states are interchanged with respect to the electron. Actually, the negative spin does not open up two components like the positive spin. We identify that negative spin states have a fractional charge. The remaining fraction of the charge is given by positive spin. The sum of the two charges obtained by negative and positive spin states is equal to unity. There is a need to use spin values larger than 1/2 which suggests formation of electron clusters. The number of states in the negative spin is infinite whereas there are 2S+1 states for positive spin. This infinite number of states is very appealing in view of recent experiments.
