Time Fractional Quantum Mechanics (1703.00301v1)

Abstract: A time fractional quantum framework has been introduced into quantum mechanics. A new version of the space-time fractional Schr\"odinger equation has been launched. The introduced space-time fractional Schr\"odinger equation has a new scale parameter, which is a fractional generalization of Planck's constant in quantum physics. It has been shown that the presence of a time fractional time derivative in the space-time fractional Schr\"odinger equation significantly impacts quantum mechanical fundamentals. Time fractional quantum mechanical operators of coordinate, momentum and angular momentum were defined and their commutation relationships were established. The pseudo-Hamilton operator was introduced and its Hermicity has been proven. Two new functions related to the Mittag-Leffler function have been introduced to solve the space-time fractional Schr\"odinger equation. Energy of a time fractional quantum system has been defined and calculated in terms of the newly introduced functions. It has been found that in the framework of time fractional quantum mechanics there are no stationary states, and the eigenvalues of the pseudo-Hamilton operator are not the energy levels of the time fractional quantum system. A free particle solution to the space-time fractional Schr\"odinger equation was found. A free particle space-time fractional quantum mechanical kernel has been found and expressed in terms of the H-function. Renormalization properties of a free particle solution and the space-time fractional quantum kernel were established. Some particular cases of time fractional quantum mechanics have been analyzed and discussed.
