Metal to Orthogonal Metal Transition* [PDF]
Chinese Physics Letters, 2020 Orthogonal metal is a new quantum metallic state that conducts electricity but acquires no Fermi surface (FS) or quasiparticles, and hence orthogonal to the established paradigm of Landau’s Fermi-liquid (FL). Such a state may hold the key of understanding the perplexing experimental observations of quantum metals that are beyond FL ...

Spintronic phase transition of graphene/BN/graphene van de Waals heterostructures
Results in Physics, 2022 Based on a single-orbital tight-binding (TB) Hubbard model under mean-field approximation, we study band structure and half-metallicity of zigzag graphene/boron nitride/graphene (Z-G/BN/G) trilayer nanoribbon systems.

Artilugio, 2023 METAL METAL es una pieza electroacústica creada en 2022. El material sonoro utilizado en la composición fue grabado durante la pandemia mundial de Covid-19. Aprovechando el aislamiento obligatorio, se realizaron sesiones de improvisación rítmica, tímbrica y textural con latas de aluminio. Estas se registraron con un grabador digital Zoom H4.

Photometric Metallicity and Distance Estimates for ∼136,000 RR Lyrae Stars from Gaia Data Release 3
The Astrophysical Journal, 2023 We present a sample of 135,873 RR Lyrae stars (RRLs) with precise photometric metallicity and distance estimates from our newly calibrated P – ϕ _31 – R _21 –[Fe/H]/ P – R _21 –[Fe/H] and G -band absolute magnitude–metallicity relations.

Cluster melting: new, limiting, and liminal phenomena
Advances in Physics: X, 2018 The thermodynamic behaviour of clusters and nanoscale structures is both a challenge to the statistical basis of the theory, and of paramount importance to experiment.

Cold-mode accretion : driving the fundamental mass-metallicity relation at z ∼ 2 [PDF]
, 2016 We investigate the star formation rate (SFR) dependence on the stellar mass and gas-phase metallicity relation at z = 2 with MOSFIRE/Keck as part of the ZFIRE survey. We have identified 117 galaxies (1.98 10M(circle dot) yr(-1)) SFRs. At fixed mass, low

Dependence of Small Planet Frequency on Stellar Metallicity Hidden by Their Prevalence [PDF]
, 2016 The dependence of gas giant planet occurrence rate on stellar metallicity has been firmly established. We extend this so-called planet–metallicity correlation to broader ranges of metallicities and planet masses/radii.

Photometric Metallicity of Galactic RR Lyrae Stars in the Gaia DR3 Era
GalaxiesRR Lyrae stars are pulsating variables crucial for distance determination and galactic structure studies. Metallicities of fundamental-mode (RRab) RR Lyrae stars are commonly derived from photometry using empirical relations involving the Fourier ...
