Composite higher derivative theory of gravity

Physical Review Research, 2020
We investigate a higher derivative theory that belongs to the class of composite field theories. Starting from the Yang-Mills theory based on the Lorentz group, we express the gauge vector fields in terms of the tetrad decomposition of a space-time ...

Gravitational production of vector dark matter

Journal of High Energy Physics, 2020
A model of vector dark matter that communicates with the Standard Model only through gravitational interactions has been investigated. It has been shown in detail how does the canonical quantization of the vector field in varying FLRW geometry implies a ...

Amplitudes on plane waves from ambitwistor strings

Journal of High Energy Physics, 2017
In marked contrast to conventional string theory, ambitwistor strings remain solvable worldsheet theories when coupled to curved background fields. We use this fact to consider the quantization of ambitwistor strings on plane wave metric and plane wave ...

Path integral quantization and stochastic quantization [PDF]

, 2009
Gives an overview of path integral quantization and stochastic quantization of classical mechanics and field theory. This title describes the non-Abelian gauge field, the gravitational field, and the path integral representation of quantum statistical ...

Unification of Thermal and Quantum Noises in Gravitational-Wave Detectors [PDF]

, 2023
Contemporary gravitational-wave detectors are fundamentally limited by thermal noise-due to dissipation in the mechanical elements of the test mass-and quantum noise-from the vacuum fluctuations of the optical field used to probe the test-mass position ...

Field Theory Vacuum and Entropic Dark Energy Models

Universe
While, in standard quantization, the energy spectrum of an oscillator does not depend on its mass, in Planck length deformed quantization, the energy spectrum becomes mass-dependent. That means that the field oscillator masses will source a gravitational

Topological orders, braiding statistics, and mixture of two types of twisted BF theories in five dimensions

Journal of High Energy Physics, 2022
Topological orders are a prominent paradigm for describing quantum many-body systems without symmetry-breaking orders. We present a topological quantum field theoretical (TQFT) study on topological orders in five-dimensional spacetime (5D) in which ...
