DOI: 10.1007/jhep11(2017)130
Abstract: A bstractString-localized quantum fields transforming in Wigner’s infinite-spin representations were originally introduced in [18, 19]. We construct these fields as limits of fields of finite mass m → 0 and finite spin s → ∞.… read more here.

Abstract: Feeding is regulated by defined neuronal pathways and circulating factors that ensure homeostatic balance is maintained. However, many emotion-affective pathways are also involved in communicating positive and negative valence on feeding behaviour. In 2019, several… read more here.

DOI: 10.1103/physrevd.102.085009
Abstract: Semiclassical Physics in gravitational scenario, in its first approximation (1st order) cares only for the expectation value of stress energy tensor and ignores the inherent quantum fluctuations thereof. In the approach of stochastic gravity, on… read more here.

DOI: 10.3390/universe8020093
Abstract: We revisit the physical arguments that led to the definition of the stress–energy tensor T in the Lorentz–Finsler setting (M,L) starting with classical relativity. Both the standard heuristic approach using fluids and the Lagrangian one… read more here.
