In this work we have considered a simple mechanical oscillator interacting with a single mode optical field inside a cavity in the generalized uncertainty principle (GUP) framework. Our aim is to calculate the modified noise spectrum and observe the effects of the GUP. The commutation relation that we have considered has an extra linear order momentum term along with a quadratic order term. Confronting our theoretical results with the observational results, we observe that we get a much tighter…

Generalized Uncertainty Principle for Entangled States of Two Identical Particles

In this work we determine the consequences of the quantum entanglement of a system of two identical particles when the generalized uncertainty principle (GUP) is considered. GUP is usually associated

Path Integral Action for a Resonant Detector of Gravitational Waves in the Generalized Uncertainty Principle Framework

The Heisenberg uncertainty principle is modified by the introduction of an observer-independent minimal length. In this work, we have considered the resonant gravitational wave detector in the

Problems with modified commutators

The purpose of this paper is to challenge the existing paradigm on which contemporary models of generalised uncertainty relations (GURs) are based, that is, the assumption of modified commutation

Higher-order generalized uncertainty principle applied to gravitational baryogenesis

The gravitational baryogenesis plays an important role in the study of baryon asymmetry. However, the original mechanism of gravitational baryogenesis in the radiation-dominated era leads to the

Amplified transduction of Planck-scale effects using quantum optics

The unification of quantum mechanics and gravity remains as one of the primary challenges of present-day physics. Quantum-gravity-inspired phenomenological models offer a window to explore potential

Quantum-optical tests of Planck-scale physics

Recently it was proposed to use cavity-optomechanical systems to test for quantum gravity corrections to quantum canonical commutation relations [Nat. Phys. 8, 393-397 (2012)]. Improving the

Testing generalised uncertainty principles through quantum noise

Motivated by several approaches to quantum gravity, there is a considerable literature on generalised uncertainty principles particularly through modification of the canonical position–momentum

Probing deformed commutators with macroscopic harmonic oscillators

The free evolution of high-quality factor micro- and nano-oscillators is analyzed, and the direct check against a model of deformed dynamics substantially lowers the previous limits on the parameters quantifying the commutator deformation.

Probing Planck-scale physics with quantum optics

One of the main challenges in physics today is to merge quantum theory and the theory of general relativity into a unified framework. Researchers are developing various approaches towards such a

Quantum gravitational decoherence from fluctuating minimal length and deformation parameter at the Planck scale

A scheme of gravitational decoherence due to quantum gravity effects is introduced and it is found that theDecoherence rate predicted by the model is extremal, being minimal in the deep quantum regime below the Planck scale and maximal in the mesoscopic regime beyond it.

Path integral for nonrelativistic generalized uncertainty principle corrected Hamiltonian

The generalized uncertainty principle (GUP) has brought the idea of the existence of a minimum measurable length in quantum physics. Depending on this GUP, the nonrelativistic Hamiltonian at the
