Abstract Entropic-force cosmology provides, in contrast with dark energy descriptions, a concrete physical understanding of the accelerated expansion of the universe. The acceleration appears to be a consequence of the entropy associated with the inf

It is believed that the canonical gravitational partition function associated with the two-body interacting Newton’s gravitation cannot be constructed because the concomitant integral is exponentially divergent. We showed previously that one can in

It is believed that the canonical gravitational partition function $Z$ associated to the classical Boltzmann-Gibbs (BG) distribution $\frac {e^{-\beta H}} {{\cal Z}}$ cannot be constructed because the integral needed for building up $Z$ includes an e

This paper brings together four distinct but very important physical notions: (1) Entropic force, (2) Entropy-along-a-curve, (3) Tsallis’ q -statistics, and (4) Emergent gravitation. We investigate the non additive, classical (Tsallis’) q -statis

We describe the phenomenology of the classical q-path entropy of a phase-space curve. This allows one to disclose an entropic force-like mechanism that is able to mimic some phenomenological aspects of the strong force, such as confinement, hard core

We investigate first-order approximations to both (i) Tsallis’ entropy Sq and (ii) the Sq-MaxEnt solution (called q-exponential functions eq).We use an approximation/expansion for q very close to unity. It is shown that the functions arising from t

In a recent paper Plastino and Rocca (2016) [18] we have demonstrated the possible existence of Tsallis' q-Gamow states. Now, accelerators' experimental evidence for Tsallis' distributions has been ascertained only at very high energies. Here, instea

We have studied the correlation between the photoconductivity and the dark resistivity of single ZnO microwires. We found that as-grown microwires with higher dark resistivities have higher photoconductivities. However, when the microwires are therma
