Po jednym tutaj z postów na fedi w końcu zajmę się samemu księgowością w swojej działalności w wFirma i oszczędzę na księgowym, który i tak co kwartał się już myli i mam tylko z tego powodu więcej roboty.

Przy okazji przeniosę całą firmową i własną korespondencję w jedno wirtualne biuro, które ma w ofercie gromadzenie i wysyłanie pod wskazany adres raz w miesiącu paczek i listów poza standardowym skanowaniem.

To jest najbardziej upierdliwa rzecz w życiu w drodze... Miejsc ogarniaj…

Detecting Sterile Neutrino Dark Matter at MeV Gamma-Ray Observatories
We explore the indirect detection of sterile neutrino dark matter within the gauged $U(1)_{B-L}$ extension of the Standard Model, in which three right-handed neutrinos account for neutrino masses, the baryon asymmetry, and dark matter. Focusing on the MeV mass range, we investigate two decay channels: the radiative decay $N \to νγ$, which produces a monochromatic photon, and the three-body decay $N \to e^- e^+ ν$, which leads to a 511 keV photon signal from positronium decay. Taking the upco…

Impacts of Atmospheric Carbon Species and Stellar Type on Climates of Terrestrial Planets
The climates of terrestrial planets are largely determined by the composition of their atmospheres and spectral types of their host stars. Previous studies suggest a wide range of carbon species abundances (CO\textsubscript{2}, CO, and CH\textsubscript{4}) can result from variations in reducing fluxes and stellar spectral types which influence photochemistry. However, a systematic investigation of how varying carbon species, particularly CO, affect planetary climates across wide parameter space…

Unified description of cuprate superconductors by fractionalized electrons emerging from integrated analyses of photoemission spectra and quasiparticle interference
Electronic structure of high-temperature superconducting cuprates is studied by analyzing experimental data independently obtained from two complementary spectroscopies, one, quasiparticle interference (QPI) measured by scanning-tunneling microscopy and the other, angle-resolved photoemission spectroscopy (ARPES) and by combining these two sets of data in a unified theoretical analysis. Through explicit calculations of experimentally measurable quantities, we show that a simple two-component fe…

Classification of Higgs sectors from group theoretical properties of UV gauge theories
Extended Higgs sectors are often introduced to explain phenomena beyond the standard model (BSM). The existence of multiple scalar fields may cause the Landau pole below the Planck scale. In this case, the low-energy theory may be replaced by an asymptotic-free gauge theory. In this paper, we consider an $\mathrm{SU}(2)$ gauge theory with confinement as such an ultra-violate theory of the extended Higgs sectors. We investigate the relation between scalar particle contents at the low energy and …

Magnetic field of a ring-like shape molecular cloud
We present a detailed study of the magnetic field structure in the G111 molecular cloud, a ring-like filamentary cloud within the NGC 7538 region. We utilized interstellar dust polarization from the Planck telescope to trace large-scale field orientations, starlight extinction polarization from the Kanata telescope to probe the cloud's magnetic field after foreground subtraction, and velocity gradients derived from CO isotopologues, observed with the IRAP 30m telescope, to examine dense regions…

Control of Covalent Bond Enables Efficient Magnetic Cooling
Magnetic cooling, harnessing the temperature change in matter when exposed to a magnetic field, presents an energy-efficient and climate-friendly alternative to traditional vapor-compression refrigeration systems, with a significantly lower global warming potential. The advancement of this technology would be accelerated if irreversible losses arising from hysteresis in magnetocaloric materials were minimized. Despite extensive efforts to manipulate crystal lattice constants at the unit-cell le…

Magneto-cubic and magneto-linear dependence observed in an in-plane anomalous Hall magnet
The Hall effect, particularly that arising from in-plane magnetic field, has recently emerged as a sensitive probe of quantum geometric properties in solids. Especially in trigonal systems, in-plane anomalous Hall effect (AHE) can be explicitly induced by nontrivial off-diagonal coupling between the magnetic field and the Hall vector on the principal plane. Here we elucidate multipolar dependence of the off-diagonal coupling in the in-plane AHE, by systematically measuring on the (001) principa…
