A new proposal of Hamiltonians to explain quantum effects

Abstract

To study the Slonczewski Spin Transfer Torque Effect in the quantum limit, a new model of Hamiltonian is needed. In recent years, it has been found that the requirement of Hermitian Hamiltonians can be replaced by a weaker condition that is the PT symmetry. This new theory allows a whole new branch of Hamiltonians to be accepted by the quantum theory. It is believed that these Hamiltonians could help to explain unstable systems and dissipative effects. This work aims to study a purposed PT symmetric Hamiltonian, which explains the Slonczewski STT effect, to see whether the rules of Quantum Mechanics can be applied or not.
