Information geometry on groupoids: the case of singular metrics
Katarzyna Grabowska, Janusz Grabowski, Marek Kus +1
We use the general setting for contrast (potential) functions in statistical and information geometry provided by Lie groupoids and Lie algebroids. The contrast functions are defin…
Fidelity susceptibility in Gaussian Random Ensembles
Piotr Sierant, Artur Maksymov, Marek Kuś +1
The fidelity susceptibility measures sensitivity of eigenstates to a change of an external parameter. It has been fruitfully used to pin down quantum phase transitions when applied…
Geometry of quantum dynamics in infinite dimension
Janusz Grabowski, Marek Kus, Giuseppe Marmo +1
We develop a geometric approach to quantum mechanics based on the concept of the Tulczyjew triple. Our approach is genuinely infinite-dimensional and including a Lagrangian formali…
Randomness in Quantum Mechanics: Philosophy, Physics and Technology
Manabendra Nath Bera, Antonio Acín, Marek Kuś +2
This progress report covers recent developments in the area of quantum randomness, which is an extraordinarily interdisciplinary area that belongs not only to physics, but also to…
Non-signalling theories and generalized probability
Tomasz I. Tylec, Marek Kuś, Jacek Krajczok
We provide mathematicaly rigorous justification of using term "probability" in connection to the so called non-signalling theories,known also as Popescu's and Rohrlich's box worlds…
Resonances and poles in isoscattering microwave networks and graphs
Michal Lawniczak, Adam Sawicki, Szymon Bauch +2
Can one hear the shape of a graph? This is a modification of the famous question of Mark Kac "Can one hear the shape of a drum?" which can be asked in the case of scattering system…
