3D gravity, point particles and deformed symmetries
Tomasz Trześniewski
It is well known that gravity in 2+1 dimensions can be recast as Chern-Simons theory, with the gauge group given by the local isometry group, depending on the metric signature and…
Quantum gravity phenomenology at the dawn of the multi-messenger era -- A review
A. Addazi, J. Alvarez-Muniz, R. Alves Batista +157
The exploration of the universe has recently entered a new era thanks to the multi-messenger paradigm, characterized by a continuous increase in the quantity and quality of experim…
Spectral dimensions and dimension spectra of quantum spacetimes
Michał Eckstein, Tomasz Trześniewski
Different approaches to quantum gravity generally predict that the dimension of spacetime at the fundamental level is not 4. The principal tool to measure how the dimension changes…
Hunting for gravitational quantum spikes
Andrzej Góźdź, Włodzimierz Piechocki, Grzegorz Plewa +1
We present the result of our examination of quantum structures called quantum spikes. The classical spikes, that are known in gravitational systems, occur in the evolution of the i…
Gauge fields and quantum entanglement
Jakub Mielczarek, Tomasz Trześniewski
The purpose of this letter is to explore the relation between gauge fields, which are at the base of our understanding of fundamental interactions, and the quantum entanglement. To…
Quantum Euclidean and Poincaré symmetries from contraction limits
Jerzy Kowalski-Glikman, Jerzy Lukierski, Tomasz Trześniewski
Following the recently obtained complete classification of quantum-deformed , and algebras, characterized by classical -…
Effective Chern-Simons actions of particles coupled to 3D gravity
Tomasz Trześniewski
Point particles in 3D gravity are known to behave as topological defects, while gravitational field can be expressed as the Chern-Simons theory of the appropriate local isometry gr…
Nonlinear Field Space Cosmology
Jakub Mielczarek, Tomasz Trześniewski
We consider the FRW cosmological model in which the matter content of universe (playing a role of inflaton or quintessence) is given by a novel generalization of the massive scalar…
Nonlinear Field Space Theory and Quantum Gravity
Tomasz Trześniewski
Phase spaces with nontrivial geometry appear in different approaches to quantum gravity and can also play a role in e.g. condensed matter physics. However, so far such phase spaces…
Spectral dimension with deformed spacetime signature
Jakub Mielczarek, Tomasz Trześniewski
Studies of the effective regime of loop quantum gravity (LQG) revealed that, in the limit of Planckian curvature scales, spacetime may undergo a transition from the Lorentzian to E…
