Seesaw and Axion in No-Scale Gravity
Anamaria Hell, Lincoln da S. Pereira, Tsutomu T. Yanagida
The No-Scale gravity is a compelling framework to describe particle physics, gravity and cosmology, in which all mass scales are an illusion given by the value of a scalar field $ϕ…
AI's Capability in Assisting Scientific Research in Physics, Astrophysics, and Cosmology II: Project Planning and Proposal Evaluation
Jia Liu, Veena Krishnaraj, Kateryna Vovk +18
We investigate how well large language models (LLMs) can assist scientific project planning and proposal evaluation. One-page project plans were independently generated for eight e…
AI's Capability in Assisting Scientific Research in Physics, Astrophysics, and Cosmology I: Literature Review
Anamaria Hell, Kateryna Vovk, Veena Krishnaraj +18
We investigate how well large language models (LLMs) can assist with literature reviews for scientific research. We perform a controlled study of eight expert-conceived research pr…
Wick-connected theories and Lorentz violation
Niklas Götzberger, Anamaria Hell
We consider double Wick rotation in field theories, which analytically continues the time coordinate, and then reinterprets one of the spatial directions as the new Lorentzian time…
LLMs with in-context learning for Algorithmic Theoretical Physics
Anamaria Hell, Leander Thiele
There is an increasing number of algorithmic computations in theoretical physics. These, while conceptually simple, can nevertheless be time-consuming and contain subtleties that s…
How to deal with conformal and pure scale-invariant theories of gravity in d dimensions?
Anamaria Hell, Dieter Lust
Conformally-invariant and pure, scale-invariant theories of gravity are particularly interesting in four or higher dimensions. Yet, in contrast to their four-dimensional counterpar…
Branching Universes
Anamaria Hell, Tatsuya Daniel
We propose the idea that our Universe is a realization among different possible branches, which can be observationally tested through the modified dispersion relation of the gravit…
Pathologies of dimension-zero scalar fields
James M. Cline, Anamaria Hell
It has been claimed in a series of papers that scalar fields with a fourth-order Lagrangian can solve the cosmological constant problem by canceling the loop contri…
On the Kalb-Ramond field with non-minimal coupling to gravity
Anamaria Hell, Ippei Obata
We consider a massive Kalb-Ramond field with a general non-minimal coupling to gravity. We first study the theory in flat space-time, taking into account the non-linearities. We sh…
The recipe for the degrees of freedom
Anamaria Hell, Elisa G. M. Ferreira, Dieter Lust +1
We consider the question of counting the degrees of freedom in theoretical models, with an emphasis on theories of fields and gravity. Among the possible approaches, the Hamiltonia…
