Phenomenological Qunatum Gravity: the birth of a new frontier?
http://arxiv.org/abs/astro-ph/0501581

If you can overlook the spelling error in the title, it is otherwise an entertaining read.

This could be the start of an interesting thread on QG Phenomenology.
The paper makes it clear that a lot has been written recently---it is a rapidly growing field of research.
It gives a bunch of references to QGP papers.
Another way to get a QG Phenomenology reading list is to put
Amelino-Camelia into the arxiv search engine

Chronos is phenomenological QG the same as QG phenom? Sounds like a silly question. Must be. I will try a keyword search and see what turns up.

http://arxiv.org/find/grp_physics/1/AND+abs:+AND+quantum+gravity+abs:+phenomenology/0/1/0/all/0/1

this was for keywords quantum gravity phenom in the abstract and produced 93 titles (predictably a fair number are by Amelino-Camelia)

This search misses what is, in my view (and I expect also in yours Chronos) the most hard-core QG phenom paper to appear so far:
Smolin's Falsifiable Predictions...
http://arxiv.org/abs/hep-th/0501091
where he lays his stack of chips on the GLAST 2007 line.

wolram has this related thread

"The Search for Quantum Gravity Signals"

I guess that is what QG Phenomenology is about---figuring out ways in which the different QG models can leave their signature in the phenomena we observe

wolram flags a good recent paper there

Indeed, the paper referenced by wolram is quite similar - and a lot bigger. Aloisio et al made liberal reference to papers by Amelino-Camelia, so it's fair to say the term phenomenology is used with the same intent. I agree wrt Smolin, he appears to be among the few who are not catagelophobic

It isn't relevant to the physics, but the fact that the author's native language isn't English is pretty clear.

It also sounds like a lot of the effort is "backwards". He is basically preparing error bars around how precisely we can show Lorentz Invariance is accurate, so as to rule out some theories, but not others.
 

What is phenomenological quantum gravity?

Phenomenological quantum gravity is a theoretical approach that aims to reconcile the principles of quantum mechanics and general relativity in order to understand the fundamental nature of space and time at a quantum level. It is a framework that combines aspects of both quantum mechanics and general relativity to study the behavior of gravity on a microscopic scale.

How does phenomenological quantum gravity differ from other theories of quantum gravity?

Unlike other theories of quantum gravity, phenomenological quantum gravity does not propose a specific mathematical model or set of equations. Instead, it focuses on studying the macroscopic consequences of quantum gravity through phenomenological models and experimental observations. This allows for a more flexible and empirical approach to understanding the effects of quantum gravity on the macroscopic world.

What are some key challenges in studying phenomenological quantum gravity?

One of the main challenges in studying phenomenological quantum gravity is the lack of experimental evidence. Since the effects of quantum gravity are expected to be extremely small and difficult to observe, it is challenging to design experiments that can test its predictions. Additionally, there is still much debate and disagreement among scientists about the fundamental principles of quantum gravity, making it difficult to develop a unified theory.

What are some potential applications of phenomenological quantum gravity?

Phenomenological quantum gravity has the potential to provide insights into the behavior of gravity in extreme environments, such as black holes or the early universe. It may also have implications for the development of new technologies, such as quantum computing, which relies on our understanding of quantum mechanics.

What are some current research efforts in the field of phenomenological quantum gravity?

Current research efforts in phenomenological quantum gravity include developing new mathematical models and experimental techniques to test the predictions of quantum gravity. There is also ongoing research on how to reconcile the principles of quantum mechanics and general relativity, as well as exploring the potential implications of quantum gravity for cosmology and the nature of time.
