We study the noncommutative corrections to the entropy of the Reissner-Nordstr\"{o}m black hole using a $\kappa$-deformed scalar probe within the brick-wall framework. The noncommutativity is encoded in an Abelian Drinfeld twist constructed from the

Black hole (BH) perturbation is followed by a ringdown phase which is dominated by quasinormal modes (QNM). These modes may provide key signature of the gravitational waves. The presence of a deformed spacetime structure may distort this signal. In o

The entanglement entropy is a fundamental quantity which characterizes the correlations between sub-systems in a larger quantum-mechanical system. For two sub-systems separated by a surface the entanglement entropy is proportional to the area of the

We present Lie-algebraic deformations of Minkowski space with undeformed Poincare algebra. These deformations interpolate between Snyder and kappa-Minkowski space. We find realizations of noncommutative coordinates in terms of commutative coordinates

Organizacija izlaganja je slijedeća. Započinje se sa kratkim opisom običnog racionalnog Calogerovog modela i predočuju se njegova rješenja unutar algebarskog pristupa. Algebarski pristup omogućava elegantno nalaženje spektra, kao i mogućnost

A quantum matrix oscillator model is shown to reproduce the quantum Hall states in a direct way and is intimately related to the regularized matrix model introduced by Polychronakos. By transferring the consideration to the Bargmann representation wi

The rational Calogero model is one of the most famous and exaustively studied examples of integrable systems. Since its inception more than thirty years ago [1], the model and its various descendants continue to be of interest for both physics and ma

A one-dimensional model with F interacting families of Calogero-type particles is studied. The model includes harmonic, two-body and three-body interactions. We emphasize the universal SU(1, 1) structure of the model. We show how SU(1, 1) generators
