Results are reported of an experimental search for the unique, rapidly varying temporal pattern solar axions coherently converting into photons via Primakoff effect in a single crystal germanium detector when incident at Bragg angle with crystalline plane. The analysis 1.94 kg yr data from 1 DEMOS Sierra Grande, Argentina, yields new laboratory bound by axion-photon coupling...
Finite-size effects have been a major and justifiable source of concern for studies many-body localization, several works dedicated to the subject. In this paper, however, we discuss yet another crucial problem that has received much less attention, lack self-averaging consequent danger reducing number random realizations as system size increases. By taking into account considering ensembles with large samples all sizes analyzed, find generalized dimensions eigenstates disordered Heisenberg...
The quantum mechanical problem of a hydrogen atom placed at the center an impenetrable sphere radius r 0 is solved by using two different methods, where, in first, trial wave function, consisting hydrogen-like function times cutoff factor that ensures fulfillment Dirichlet boundary condition, proposed, whereas second, radial Schrödinger equation means accurate numerical technique. We computed energies for ground and first excited states S-, P-, D-symmetry, as well dipole transitions,...
ANAIS is a direct dark matter detection experiment whose goal to confirm or refute in model independent way the positive annual modulation signal claimed by DAMA/LIBRA. Consisting of 112.5 kg NaI(Tl) scintillators, ANAIS-112 taking data at Canfranc Underground Laboratory Spain since August, 2017. Results corresponding analysis three years are compatible with absence and incompatible However, testing this relies on knowledge scintillation quenching factors (QF), which measure relative...
A thorough understanding of the background sources is mandatory in any experiment searching for rare events. The ANAIS (Annual Modulation with NaI(Tl) Scintillators) aims at confirmation DAMA/LIBRA signal Canfranc Underground Laboratory (LSC). Two crystals 12.5 kg each produced by Alpha Spectra have been taking data since December 2012. complete model these detectors and more precisely region interest will be described. Preliminary analysis a new crystal received March 2015 presented too....
Two germanium detectors are currently operating in the Canfranc Underground Laboratory at 2450 m.w.e looking for WIMP dark matter. One is a 2 kg 76Ge IGEX detector (RG-2) which has an energy threshold of 4 keV and low-energy background rate about 0.3 c/keV/kg/day. The other small (234 g) natural abundance Ge (COSME), low (2.5 keV) resolution 0.4 10 WIMPs solar axions. analysis 73 kg-days data taken by COSME search axions via their photon Primakoff conversion Bragg scattering crystal yields...
