Minimal length uncertainty relation and ultraviolet regularization

Abstract: Studies in string theory and quantum gravity suggest the existence of a finite lower limit ∆x 0 to the possible resolution of distances, at the latest on the scale of the Planck length of 10 −35 m. Within the framework of the euclidean path integral we explicitly show ultraviolet regularisation in field theory through this short distance structure. Both rotation and translation invariance can be preserved. An example geometry is studied in detail.

“…An important feature of the existence of a minimal length is the modification of the standard Heisenberg commutation relation in the usual quantum mechanics [7,8]. Such relations are known as the Generalized Uncertainty Principle (GUP).…”

“…The problems with deformed Heisenberg algebra with small additions to the canonical commutational relations have been under a thorough and versatile scrutiny for a period of time [1][2][3][4][5][6][7][8][9][10]. Deformed commutational relations were studied for the first time in [11] where this issue was raised in connection with the idea of quantisation of space.…”

“…It is an old idea [33,34] that a noncommutative modification of the algebraic structure of space-time could provide a regularization of the divergences of quantum field theory, because the representations of noncommutative 'spaces' have a lattice-like structure [25,22,26,20,5] which should automatically impose an ultraviolet cut-off [14,9]. This idea has been challenged recently from various points of view [21,8,28,29,32].…”
