MOND from Second-Order Moment Modified Acceleration and Quantum Equivalence Principle
M. J. Luo
This paper proposes a novel non-inertial quantum effect wherein particle spectra show second-order moment extra Gaussian broadening due to local short-time (non-uniform) accelerati…
Quantum Mechanics Relative to a Quantum Reference System: a Relative State Approach
M. J. Luo
This paper proposes an intrinsic or background-independent quantum framework based on entangled state rather than absolute quantum state, it describes a quantum relative state betw…
Well-posedness of Ricci Flow in Lorentzian Spacetime and its Entropy Formula
M. J. Luo
This paper attempts to construct monotonic entropy functionals for four-dimensional Lorentzian spacetime under physical boundary conditions, as an extension of Perelman's monotonic…
Second-Order Moment Quantum Fluctuations and Quantum Equivalence Principle
M. J. Luo
The second-order moment quantum fluctuations or uncertainties are mass-dependent, and the incompatibility between the quantum uncertainty principle and the equivalence principle is…
Local Short-Time Acceleration induced Spectral Line Broadening and Possible Implications in Cosmology
M. J. Luo
The paper proposes an acceleration effect that a local short-time acceleration produces an additional broadening to spectral line, while the central value of the line remains unaff…
A Statistical Fields Theory underlying the Thermodynamics of Ricci Flow and Gravity
M. J. Luo
The paper proposes a statistical fields theory of quantum reference frame underlying the Perelman's analogies between his formalism of the Ricci flow and the thermodynamics. The th…
Quantum Modified Gravity at Low Energy in the Ricci Flow of Quantum Spacetime
M. J. Luo
Quantum treatment of physical reference frame leads to the Ricci flow of quantum spacetime, which is a quite rigid framework to quantum and renormalization effect of gravity. The t…
Local Conformal Instability and Local Non-Collapsing in the Ricci flow of Quantum Spacetime
M. J. Luo
It is known that the conformal instability or bottomless problem rises in the path integral method in quantizing the general relativity. Does quantum spacetime itself really suffer…
The Ricci Flow and the Early Universe
M. J. Luo
A framework of quantum spacetime reference frame is proposed and reviewed, in which the quantum spacetime at the Gaussian approximation is deformed by the Ricci flow. At sufficient…
Trace Anomaly, Perelman's Functionals and the Cosmological Constant
M. J. Luo
The trace anomaly and the cosmological constant problem are two typical breakdowns when applying the quantum principle to a general covariant or gravitational system. A quantum the…
Extremal rotating black holes, scalar perturbation and superradiant stability
Jia-Mao Lin, Ming-Jian Luo, Zi-Han Zheng +2
A (charged) rotating black hole may be unstable against a (charged) massive scalar field perturbation due to the existence of superradiance modes. The stability property depends on…
Analytic study of superradiant stability of Kerr-Newman black holes under charged massive scalar perturbation
Jun-Huai Xu, Zi-Han Zheng, Ming-Jian Luo +1
The superradiant stability of a Kerr-Newman black hole and charged massive scalar perturbation is investigated. We treat the black hole as a background geometry and study the equat…
The Cosmological Constant Problem and Quantum Spacetime Reference Frame
M. J. Luo
This paper is a generalization of earlier papers [Nucl. Phys. B 884, 344 (2014) (arXiv:1312.2759) and JHEP 6, 63 (2015) (arXiv:1401.2488)]. We generalize the idea of quantum clock…
Dark Energy from Quantum Uncertainty of Distant Clock
M. J. Luo
The observed cosmic acceleration was attributed to an exotic dark energy in the framework of classical general relativity. The dark energy behaves very similar with vacuum energy i…
The Cosmological Constant Problem and Re-interpretation of Time
M. J. Luo
We abandon the interpretation that time is a global parameter in quantum mechanics, replace it by a quantum dynamical variable playing the role of time. This operational re-interpr…
