In phenomenological quantum gravity theories, Planckian behavior is triggered by the energy of elementary particles approaching the Planck energy, ${E}_{P}$, but it is also possible that anomalous behavior strikes systems of particles with total energy near ${E}_{P}$. This is usually perceived to be pathological and has been labeled ``the soccer ball problem.'' We point out that there is no obvious contradiction with experiment if coherent collections of particles with bulk energy of order ${E… 
Nanodiamond interferometry meets quantum gravity
Interferometry with massive particles may have the potential to explore the limitations of standard quantum mechanics in particular where it concerns its boundary with general relativity and the yet
Exact ultra cold neutrons’ energy spectrum in gravitational quantum mechanics
We find exact energy eigenvalues and eigenfunctions of the quantum bouncer in the presence of the minimal length uncertainty and the maximal momentum. This form of Generalized (Gravitational)
Coherent States in Gravitational Quantum Mechanics
We present the coherent states of the harmonic oscillator in the framework of the generalized (gravitational) uncertainty principle (GUP). This form of GUP is consistent with various theories of
Minimal Length Scale Scenarios for Quantum Gravity
TLDR
The question of whether the fundamental laws of nature limit the ability to probe arbitrarily short distances is reviewed, and what insights can be gained from thought experiments for probes of shortest distances are examined.
Investigation on Planck scale physics by the AURIGA gravitational bar detector
We have recently shown that the very low mechanical energy achieved and measured in the main vibration mode of gravitational wave bar detectors can set an upper limit to possible modifications of the
Relative locality and the soccer ball problem
We consider the behavior of macroscopic bodies within the framework of relative locality [G. Amelino-Camelia, L. Freidel, J. Kowalski-Glikman, and L. Smolin, arXiv:1101.0931]. This is a recent
How does causality protection constrain the form of physical law
It's well known that a naive approach to quantising gravity leads to causality violation and or infinite energies. Both of which would allow one to surpass the limit of what is Turing-computable. I
Formulation of the Spinor Field in the Presence of a Minimal Length Based on the Quesne-Tkachuk Algebra
In 2006 Quesne and Tkachuk (J. Phys. A: Math. Gen.39, 10909, (2006)) introduced a (D+1)-dimensional (β, β′)-two-parameter Lorentz-covariant deformed algebra which leads to a nonzero minimal length.
Quantum Field Theory with a Minimal Length Induced from Noncommutative Space
From the inspection of noncommutative quantum mechanics, we obtain an approximate equivalent relation for the energy dependence of the Planck constant in the noncommutative space, which means a
