Thermodynamics of the Van der Waals black hole within nonextensive Kaniadiakis entropy
Adam Z. Kaczmarek, Yassine Sekhmani, Dominik Szczęśniak +1
In this work, we have studied the thermodynamic properties of the Van der Waals black hole in the framework of the nonextensive Kaniadakis entropy. We have shown that the black hol…

Cosmological aspects of the unimodular-mimetic gravity
Adam Z. Kaczmarek, Dominik Szczęśniak
In this work we introduce and study the unimodular-mimetic gravity, where unimodular and mimetic constraints are incorporated through corresponding Lagrange multip…
