In the shell model of nuclei, protons and neutrons move in a phenomenological nuclear potential much in the same manner as electrons move in Coulomb based potential in the shell model of atoms. As in the atomic case, the protons and neutrons of certain nuclear energy levels will have a non-zero orbital angular momentum (i.e. l =/= 0) and will therefore experience a centripetal potential and a centripetal acceleration. We advance the hypothesis, based on justification via the path integral formalism, that if one associates an Unruh temperature with this quantum centripetal acceleration then there is a potentially experimentally observable effect on certain nuclei -- the shifting of the naive expectations of the relative occupation of the ground and lowest lying energy levels. In particular we find that this effect should be most prominent in Li-7 nuclei. We speculate that this effect of the Unruh temperature might offer an answer to the Li-7 problem in Big Bang Nucleosynthesis.
We propose a test for the circular Unruh effect using certain atoms - fluorine and oxygen. For these atoms the centripetal acceleration of the outer shell electrons implies an effective Unruh temperature in the range 1000 - 2000 K. This range of Unru
A uniformly accelerated charged particle feels the vacuum as thermally excited and fluctuates around the classical trajectory. Then we may expect additional radiation besides the Larmor radiation. It is called Unruh radiation. In this report, we revi
Total entropy generated by the Unruh effect is calculated within the framework of information theory. In contrast to previous studies, here the calculations are done for the finite time of existence of the non-inertial reference frame. In this case o
We study coefficients of axial chiral vortical effect and chiral separation effect at finite temperature and vector chemical potential in massive theories. We present two independent methods of calculating the coefficients: one from field theory and
We report on the measurement of the $^{7}$Be($n, p$)$^{7}$Li cross section from thermal to approximately 325 keV neutron energy, performed in the high-flux experimental area (EAR2) of the n_TOF facility at CERN. This reaction plays a key role in the
