Niccolo Loret and the possibilities of the Planck-scale
Print page
Niccolo Loret, the picture is taken from the website.
Niccolo Loret is a researcher from NEWFELPRO's incoming scheme, who has successfully completed his one year long project called "Looking for the Planck-scale patterns and cosmology" (LPPC) at the Ruđer Bošković Institute in Zagreb, under the mentorship of Stjepan Meljanac, PhD
Within his project he found a simple way to express Planck-scale effects as deformations to physical models in a curved space-time framework, defining a momentum-dependent space-time metric (in some aspects similar to the Rainbow Metrics phenomenology, but with a more formal mathematical approach). Cosmology is the most suitable arena to test those tiny effects, since long time-scales and its elevated characteristic energies would eventually magnify Planck-scale physics deformations (of course assuming those effects actually take place). With the project results he can define a coherent cosmological model which formalizes many of the features arising from deformed spacetime symmetries models. This theoretical formulation can propose a clear set of phenomenological tests, to try to understand the role of Planckian effects in early universe and begin to set upper bounds on many theoretical models.
During the implementation of his project, he has written and published following papers:

Also, he participated at the following scientific events:
- Workshop in Turin (Cavallerizza Reale) about testing quantum gravity (2016).
- 37th Max Born Symposium in Wroclaw (Poland) in 2016. He had an oral presentation titled „The interplay between Finsler geometry and curved momentum-space formalism.“
- 21th International Conference on General Relativity "GR21" in New Yorku.
After he finished his NEWFELPRO project, Niccolo Loret continued his research on macroscopic manifestation of thew Planck-scale phenonomena.
We wish him further success!
