Universally finite gravitational and gauge theories
Nuclear Physics B, 2015 It is well known that standard gauge theories are renormalizable in D=4 while Einstein gravity is renormalizable in D=2. This is where the research in the field of two derivatives theories is currently standing.

Chern-Weil global symmetries and how quantum gravity avoids them
Journal of High Energy Physics, 2021 We draw attention to a class of generalized global symmetries, which we call “Chern-Weil global symmetries,” that arise ubiquitously in gauge theories. The Noether currents of these Chern-Weil global symmetries are given by wedge products of gauge field ...

Predicting the flavour and SUSY flavour structure from grand unified theories [PDF]
, 2016 Grand Unified Theories (GUTs) offer an attractive framework for flavour models, since they feature relations between quarks and leptons. Combining them with Supersymmetry (SUSY) and flavour symmetries, we derive predictions for the flavour and SUSY ...

Quantum Humeanism, or: physicalism without properties [PDF]
, 2014 In recent literature, it has become clear that quantum physics does not refute Humeanism: Lewis’s thesis of Humean supervenience can be literally true even in the light of quantum entanglement.

Interacting diffusive unified dark energy and dark matter from scalar fields
European Physical Journal C: Particles and Fields, 2017 Here we generalize ideas of unified dark matter–dark energy in the context of two measure theories and of dynamical space time theories. In two measure theories one uses metric independent volume elements and this allows one to construct unified dark ...

Unified approach to quantum and classical dualities. [PDF]
Physical Review Letters, 2009 We show how classical and quantum dualities, as well as duality relations that appear only in a sector of certain theories (emergent dualities), can be unveiled, and systematically established.

Quasilocalized dynamics from confinement of quantum excitations [PDF]
, 2019 Confinement of excitations induces quasilocalized dynamics in disorder-free isolated quantum many-body systems in one spatial dimension. This occurrence is signaled by severe suppression of quantum correlation spreading and of entanglement growth, long ...

Proton stability in grand unified theories, in strings and in branes [PDF]
, 2006 A broad overview of the current status of proton stability in unified models of particle interactions is given which includes non-supersymmetric unification, SUSY and SUGRA unified models, unification based on extra dimensions, and string-M-theory models.

Dynamical models for light Higgs doublets in supersymmetric grand unified theories. [PDF]
Physical Review D, Particles and fields, 1995 We consider a supersymmetric hypercolor gauge theory with six flavors of (hyper)quarks interacting strongly at the grand unification scale. Dynamical breaking of the grand unified SU(5${)}_{\mathrm{}\mathrm{GUT}}$ produces a massless pair of composite ...
