[phys4phys] Group for Gravitation, Particle and Fields seminar, Tuesday 5 September 2023

[Marija Dimitrijevic Ciric]

Dear colleagues,

You are cordially invited to the seminar of the Group for Gravitation, 
Particles and Fields, which will be held on Tuesday, 5 September 2023 at 
11:00 at the Institute of Physics, lecture hall 360.


The talk entitled

Quantum gravity = Gravitized quantum theory

will be given by Djordje Minic (Department of Physics, Virginia Tech).

Abstract: In this talk I will discuss a new approach to the problem of 
quantum gravity in which the quantum mechanical structures that are 
traditionally fixed, such as the Fubini-Study metric in the Hilbert 
space of states, become dynamical and so implement the idea of 
gravitizing the quantum. I will elaborate on a specific test of this new 
approach to quantum gravity using triple interference in a varying 
gravitational field. My discussion will be driven by a profound analogy 
with recent triple-path interference experiments performed in the 
context of non-linear optics. I will emphasize that the triple 
interference experiment in a varying gravitational field would deeply 
influence the present understanding of the kinematics of quantum gravity 
and quantum gravity phenomenology. I will also discuss the non-linear 
Talbot effect as another striking phenomenological probe of 
gravitization of the geometry of quantum theory. Finally, I will discuss 
the bounds this new approach to quantum gravity implies for the 
cosmological constant, the Higgs mass and the masses and mixing matrices 
of quarks and leptons.
