“…It has been demonstrated that such a zero point length in the background geometry of spacetime can modify the low energy quantum mechanical systems, as it will modify the Heisenberg uncertainty principle to a generalized uncertainty principle [18,19,20,21]. It has also been proposed that this zero point length can be much larger than the Planck length, and this can produce effects which can be measured using present experimental data [22,23].…”

“…This deformation of the Heisenberg algebra would also deform the coordinate representation of the momentum operators to [18,19,20,21]. It has also been proposed that such a deformation of the Heisenberg algebra from a zero point length, much greater than the string length can be detected using optomechanical setup [24,25,26,27].…”

“…It is known that such a zero point length in the background geometry of spacetime modifies the Heisenberg uncertainty principle, producing a generalized uncertainty principle [18,19,20,21]. This generalized uncertainty principle, which occurs due to a zero point length, can be written as [18,19,20,21],…”

Using T-duality, we will argue that a zero point length exists in the low energy effective field theory of string theory on compactified extra dimensions. Furthermore, if we neglect all the oscillator modes, this zero point length would modify low quantum mechanical systems. As this zero length is fixed geometrically, it is important to analyze how it modifies purely quantum mechanical effects. Thus, we will analyze its effects on quantum erasers, because they are based on quantum effects like entanglement. It will be observed that the behavior of these quantum erasers gets modified by this zero point length. As the zero point length is fixed by the radius of compactification, we argue that this results demonstrate a deeper connection between geometry and quantum effects.

“…It is important to know that by computing the entropy density also one can find the effect of modified dispersion relation (2) on the bulk to shear viscosity ratio as an extractable quantity in relativistic heavy ion collisions [51]. Note that in a first order phase transition, some energy will be released in the medium.…”

Planck scale effects on the stochastic gravitational wave background generated from cosmological hadronization transition: A qualitative study

We reconsider the stochastic gravitational wave background spectrum produced during the first order hadronization process, in presence of ultraviolet cutoffs suggested by the generalized uncertainty principle as a promising signature towards the Planck scale physics. Unlike common perception that the dynamics of QCD phase transition and its phenomenological consequences are highly influenced by the critical temperature, we find that the underlying Planck scale modifications can affect the stochastic gravitational spectrum arising from the QCD transition without a noteworthy change in the relevant critical temperature. Our investigation shows that incorporating the natural cutoffs into MIT bag equation of state and background evolution leads to a growth in the stochastic gravitational power spectrum, while the relevant redshift of the QCD era, remains unaltered. These results have double implications from the point of view of phenomenology. Firstly, it is expected to enhance the chance of detecting the stochastic gravitational signal created by such a transition in future observations. Secondly, it gives a hint on the decoding from the dynamics of QCD phase transition.

“…It has been indicated that the equation of state (EoS) of an ideal Quark Gluon Plasma (QGP) is modified, when the GUP is applied, as a consequence of the modifications occurred to the corresponding thermodynamical quantities [21][22][23]. The speed of sound and the entropy density was computed after considering GUP effect on EoS of an Ideal QGP [24].…”

The QCD phase transition exhibits different periods during the evolution time of the universe. We explore the cosmological implications of QCD phase transition in the early universe, which was mainly full of QGP matter, through the Friedmann equations. This is performed by studying the effect of GUP on the MIT bag model. The obtained modified MIT bag model alongside with the Friedmann equations are utilized to study the thermodynamical quantities in terms of the evolution time. The effect of GUP is set by inserting the parameter α = 10 −5 GeV −1 . It is found that, the GUP effect on the evolution time of the universe makes it shorter, i.e the time span of each phase takes shorter time to transfer to another phase than their corresponding ones without GUP effect.
