ABSTRACT Some properties of a neutrino may differ significantly depending on whether it is Dirac or Majorana type. The type is determined by the relative size of Dirac and Majorana masses, which may vary if they arise from an oscillating scalar dark matter. One of the unrevealed properties of the neutrinos is whether they are Dirac type or Majorana type. Some important physics occur only for the Majorana type; the leptogenesis that can explain the baryon asymmetry of the universe (BAU) and the seesaw mechanism that can explain the smallness of the neutrino masses. Experiments such as neutrinoless double beta decay can expect signals only for the Majorana neutrinos. The true nature of the neutrinos may not be simple enough to identify them as either Dirac or Majorana type, though. It is especially so in view that the properties of dark matter, which is another mystery in particle physics, are also unrevealed. It is quite possible that neutrino and dark matter are tightly linked, affecting each other. Especially, the Majorana neutrino requires a Majorana mass, which might originate from dark matter. In this letter, we propose a new scenario in which the dark matter may convert the type of neutrinos, adopting a slowly oscillating scalar dark matter whose value serves as the Majorana mass. We show the oscillation can be large enough to change it back and forth between the Dirac and Majorana types while satisfying all the constraints for dark matter. Interestingly, the scenario provides distinct phenomenology both in the present-time neutrino phenomenology and early universe physics. Coupling an oscillating scalar field to vary the particle mass is not new, including the neutrino masses [1–7]. Previous works on neutrinos with varying Majorana mass via ultra-light dark matter considered the effects of small modulations only either within the quasi-Dirac type [8] or within the Majorana type [9] on neutrino flavor oscillation experiments or cosmological observables. Our study differs from the existing works in that it is the first proposal of alternating the neutrino type between the Dirac and Majorana. READ FULL LENGTH PAPER CLICK HERE

Chern insulators, which are the lattice analogs of the quantum Hall states, can potentially manifest high-temperature topological orders at zero magnetic field to enable next-generation topological quantum devices 1-4 . To date, integer Chern insulators have been experimentally demonstrated in several systems at zero magnetic field 3, 5-11, but fractional Chern insulators have been reported only in graphene-based systems under a finite magnetic field 12, 13. The emergence of semiconductor moiré materials 14, 15, which support tunable topological flat bands 16, 17, opens a new opportunity to realize fractional Chern insulators 18-20. Here, we report the observation of both integer and fractional Chern insulators at zero magnetic field in small-angle twisted bilayer MoTe2 by combining the local electronic compressibility and magneto-optical measurements. At hole filling factor 𝝂 = 𝟏 and 2/3, the system is incompressible and spontaneously breaks time reversal symmetry. We determine the Chern number to be 1 and 2/3 for the 𝝂 = 𝟏 and 𝝂 = 𝟐/𝟑 gaps, respectively, from their dispersion in filling factor with applied magnetic Read full text field using the Streda formula. We further demonstrate electric-field-tuned topological phase transitions involving the Chern insulators. Our findings pave the way for demonstration of quantized fractional Hall conductance and anyonic excitation and braiding 21 in semiconductor moiré materials.

Theoretical Physics Letters 2023 ° 02(04) ° 10-06 https://www.wikipt.org/tphysicsletters DOI: 10.1490/659774.695tpl We study gravitational wave microlensing by primordial black holes (PBHs), accounting for the effect of a particle dark matter minihalo surrounding them. Such minihaloes are expected when PBHs make up only a fraction of all dark matter. We find that the LIGO-Virgo detections imply a 1σ bound on the abundance of PBHs heavier than 50M. The next generation observatories can potentially probe PBHs as light as 0.01M and down to 2 × 10−4 fraction of all dark matter. We also show that these detectors can distinguish between dressed and naked PBHs, providing a novel way to study the distribution of particle dark matter around black holes and potentially shed light on the origins of black holes.
