Experimental Review of the Quarkonium Physics at the LHC
We review recent heavy quarkonium measurements in $pp$, $p\mathrm{Pb}$, and $\mathrm{PbPb}$ collisions at the LHC by the ALICE, ATLAS, CMS, and LHCb collaborations using Run 2 and early Run 3 data. Production studies include present differential cross sections and polarization measurements of charmonium and bottomonium, providing precise tests of QCD theoretical calculations and unveiling symmetry relations among spin and orbital configurations. Notably, a $t\bar{t}$ quasi bound state has been …

I'm not an expert, but it seems clear to me that the working class requires unions organized around revolutionary class struggle, rather than organizations limited to administering compromises within the capitalist mode of production. Traditional trade unions often confine workers to the narrow framework of collective bargaining, which has the effect of reproducing the very relations of exploitation they claim to challenge. By prioritizing incremental reforms within the existing bourgeoi…

Resonant axion and dark photon production in magnetic white dwarfs
Using magnetic white dwarfs as a case study, we show that the emission of sub-MeV bosons from stellar plasmas can be substantially modified in the presence of a magnetic field. In particular, the magnetic field-induced anisotropy and cyclotron resonance both significantly affect the in-medium dispersion relations of the Standard Model photon. As a result, resonant level crossing between photons and other light bosons occurs under environmental conditions that differ from the resonance criteria …

Inertia Tames Fluctuations in Autonomous Stationary Heat Engines
Thermodynamic uncertainty relations (TURs) provide fundamental constraints on the interplay between power fluctuations, entropy production, and efficiency in overdamped stationary autonomous heat engines. However, their validity in underdamped regimes remains limited and less explored. Here, we analytically and numerically study a physically realizable autonomous heat engine composed of two underdamped continuous degrees of freedom coupled to a two-level system. We show that this nonlinear setu…
