Research Paper: Soliton Solution of Nonlinear Schrodinger Equation in the Presence of a Minimal Observable Length [PDF]
فیزیک کاربردی ایران, 2021 The unification between the theory of general relativity and the standard model of particle physics predicts the existence of a minimal measurable length on the order of the Planck length. Nowadays phenomenological studies of field theory in the presence

On the generalized uncertainty principle and cosmology
International Journal of Modern Physics DIn this work, we study the effects of the Generalized Uncertainty Principle (GUP) in cosmology. We start with the Friedmann–Robertson–Walker (FRW) model endowed with a scalar field. After introducing the GUP modification to the model, we solve for the quantum and classical cases. Finally, we find the GUP-modified Friedmann equations.

QUANTIZATION OF FIELDS BASED ON GENERALIZED UNCERTAINTY PRINCIPLE [PDF]
Modern Physics Letters A, 2006 We construct a quantum theory of free scalar field in (1+1) dimensions based on the deformed Heisenberg algebra [Formula: see text] where β is a deformation parameter. Both canonical and path integral formalisms are employed. A higher dimensional extension is easily performed in the path integral formalism.

Generalized uncertainty principle and black hole entropy
, 2006 Recently, there has been much attention devoted to resolving the quantum corrections to the Bekenstein–Hawking black hole entropy. In particular, many researchers have expressed a vested interest in the coefficient of the logarithmic term of the black ...

On Time in Quantum Physics [PDF]
, 2012 First, I briefly review the different conceptions of time held by three rival interpretations of quantum theory: the collapse of the wave-packet, the pilot-wave interpretation, and the Everett interpretation (Section 2).

EFFECTS OF THE GENERALIZED UNCERTAINTY PRINCIPLE ON THE INFLATION PARAMETERS [PDF]
International Journal of Modern Physics D, 2010 We investigate the effects of the generalized uncertainty principle on the inflationary dynamics of the early universe from both the standard and the braneworld viewpoint. We choose the Randall–Sundrum II model as our underlying braneworld scenario. We find that the quantum-gravitational effects lead to a spectral index which is not scale-invariant ...

A generalized uncertainty principle in quantum gravity [PDF]
Physics Letters B, 1993 We discuss a Gedanken experiment for the measurement of the area of the apparent horizon of a black hole in quantum gravity. Using rather general and model-independent considerations we find a generalized uncertainty principle which agrees with a similar result obtained in the framework of string theories.

Generalized Uncertainty Principle and Extra Dimensions [PDF]
, 2018 The generalized uncertainty principle (GUP) is a modification of standard quantum mechanics due to Planck scale effects. The GUP has recently been used to improve the short distance behaviour of classical black hole spacetimes by invoking nonlocal modifications of the gravity action.
