Abstract In this work, we consider effects of the dynamical vacuum in quantum cosmology in presence of a minimum length introduced by the GUP (generalized uncertainty principle) related to the modified commutation relation $$[{\hat{X}},{\hat{P}}] :=

Abstract A minimal-length scenario can be considered as an effective description of quantum gravity effects. In quantum mechanics the introduction of a minimal length can be accomplished through a generalization of Heisenberg’s uncertainty principl

Rubber compounds contain several additives besides the elastomer matrix, such as fillers, curing agents, activators, antioxidants, among others. However, some of these additives causes a negative impact on the environment, e.g., zinc oxide commonly u

Natural rubber latex (NRL) films have high elasticity and flexibility and are excellent protection barriers against micro-organisms. For this reason, NRL is often used in the manufacture of medical products, such as gloves, condoms, blood transfusion

One of the most widely problem studied in quantum mechanics is of an infinite square-well potential. In a minimal-length scenario its study requires additional care because the boundary conditions at the walls of the well are not well fixed. In order
