The characterization of quantum processes is a key tool in quantum information processing tasks for several reasons: on one hand, it allows one to acknowledge errors in the implementations of quantum algorithms; on the other, it allows one to characterize unknown processes occurring in nature. Bende...

We investigate sharing of bipartite entanglement in a scenario where half of an entangled pair is possessed and projectively measured by one observer, called Alice, while the other half is subjected to measurements performed sequentially, independently, and unsharply, by multiple observers, called B...

We study a system of penetrable bosons on a line, focusing on the high-density/weak-interaction
regime, where the ground state is, to a good approximation, a condensate. Under compression, the
system clusterizes at zero temperature, i.e. particles gather together in separate, equally
populated bunches. We compare predictions from the Gross–Pitaevskii (GP) equation with those of two
distinct variational approximations of the single-particle state, written as either a sum of

We study generalized diffusion-wave equation in which the second order time derivative is replaced
by an integro-differential operator. It yields time fractional and distributed order time fractional
diffusion-wave equations as particular cases. We consider different memory kernels of the
integro-differential operator, derive corresponding fundamental solutions, specify the conditions of
their non-negativity and calculate the mean squared displacement for all cases. In particular, we
