Quasicrystal Tilings in Three Dimensions and Their Empires
Crystals, 2018 The projection method for constructing quasiperiodic tilings from a higher dimensional lattice provides a useful context for computing a quasicrystal’s vertex configurations, frequencies, and empires (forced tiles).

Beyond the Standard Model with Six-Dimensional Spinors
Particles, 2023 Six-dimensional spinors with Spin(3,3) symmetry are utilized to efficiently encode three generations of matter. E8(−24) is shown to contain physically relevant subgroups with representations for GUT groups, spacetime symmetries, three generations of the ...

Remarks on fermions in a dipole magnetic field
Journal of High Energy Physics, 2021 This work is a continuation of our recent study of non-relativistic charged particles, confined to a sphere enclosing a magnetic dipole at its center [1]. In this sequel, we extend our computations in two significant ways.

Proceedings of Winter School of Theoretical Physics, Second and Third Training School of COST Action CA18108 "Quantum gravity phenomenology in the multi-messenger approach" — PoS(QG-MMSchools), 2023 After introducing the covariant phase space calculus, Noether's theorems are discussed, with particular emphasis on Noether's second theorem and the role of gauge symmetries. This is followed by the enunciation of the theory of asymptotic symmetries, and later its application to gravity.

New Journal of Physics, 2012 We give a pedagogical introduction to the basic ideas and concepts of the Asymptotic Safety program in Quantum Einstein Gravity. Using the continuum approach based upon the effective average action, we summarize the state of the art of the field with a particular focus on the evidence supporting the existence of the non-trivial renormalization group ...

Spread complexity and topological transitions in the Kitaev chain
Journal of High Energy Physics, 2023 A number of recent works have argued that quantum complexity, a well-known concept in computer science that has re-emerged recently in the context of the physics of black holes, may be used as an efficient probe of novel phenomena such as quantum chaos ...

Chiral Loop Quantum Supergravity and Black Hole Entropy
Universe, 2023 Recent work has shown that local supersymmetry on a spacetime boundary in N-extended AdS supergravity in chiral variables implies coupling to a boundary OSp(N|2)C super Chern–Simons theory.

Newtonian quantum gravity. [PDF]
Physics Essays, 2010 A Newtonian approach to quantum gravity is studied. At least for weak gravitational fields it should be a valid approximation. Such an approach could be used to point out problems and prospects inherent in a more exact theory of quantum gravity, yet to be discovered. Newtonian quantum gravity, e.g., shows promise for prohibiting black holes altogether (
