Weakly interacting Bose gases with generalized uncertainty principle: Effects of quantum gravity

نویسندگان

چکیده

We investigate quantum gravity corrections due to the generalized uncertainty principle on three-dimensional weakly interacting Bose gases at both zero and finite temperatures using time-dependent Hatree–Fock–Bogoliubov theory. derive useful formulas for depletion, anomalous density, some thermodynamic quantities such as chemical potential, ground-state energy, free superfluid density. It is found that presence of a minimal length leads modify fluctuations condensate its properties in weak strong gravitational regimes. Unexpectedly, interplay effects stemming from interactions may lift fractions. show minimizes interaction force between bosons leading formation ultradilute condensates. Our results which can be readily probed current experiments offer new attractive possibility understand framework mechanics.

A Generalized Uncertainty Principle in Quantum Gravity

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. The result indicates that a minimum length of the order of the Planck length emerges natu...

Tests of Quantum Gravity via Generalized Uncertainty Principle

In this paper we propose a way of determining the subleading corrections to the BekensteinHawking black hole entropy by considering a modified generalized uncertainty principle with two parameters. In the context of modified generalized uncertainty principle, coefficients of the correction terms of black hole entropy are written in terms of combination of the parameters. We also calculate corre...

Low-dimensional weakly interacting Bose gases: Nonuniversal equations of state

The zero-temperature equation of state is analyzed in low-dimensional bosonic systems. We propose to use the concept of energy-dependent s-wave scattering length for obtaining estimations of nonuniversal terms in the energy expansion. We test this approach by making a comparison to exactly solvable one-dimensional problems and find that the generated terms have the correct structure. The applic...

Quantum groups, gravity, and the generalized uncertainty principle.

We investigate the relationship between the generalized uncertainty principle in quantum gravity and the quantum deformation of the Poincaré algebra. We find that a deformed Newton-Wigner position operator and the generators of spatial translations and rotations of the deformed Poincaré algebra obey a deformed Heisenberg algebra from which the generalized uncertainty principle follows. The resu...

On the Transition Temperature for Weakly-Interacting Homogeneous Bose Gases

We apply the nonperturbative optimized linear δ expansion method to the O(N) scalar field model in three-dimensions to determine the transition temperature of a dilute homogeneous Bose gas. Our results show that the shift of the transition temperature, ∆Tc/Tc, of the interacting model, compared with the ideal gas transition temperature, really behaves as γan1/3 where a is the s-wave scattering ...
