Autonomous quantum heat engine based on non-Markovian dynamics of an optomechanical Hamiltonian

Scientific Reports
We propose a recipe for demonstrating an autonomous quantum heat engine where the working fluid consists of a harmonic oscillator, the frequency of which is tuned by a driving mode.

Highly Variable Methane Production and Fluxes in a Hypereutrophic Lake Despite Uniform Bathymetry and Sediment Chemistry

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Hypereutrophic lakes support high sedimentation of labile organic carbon, promoting sediment anoxia and GHG potential production. Lakes with complex morphometry exhibit extensive spatial heterogeneity in sediment methane (CH4) and carbon dioxide CO2 dynamics. We wondered: do lakes with uniform bathymetry show low spatial variation in sediments'

QCD exotics [PDF]

Hyperfine Interactions, 2014
QCD-motivated models for hadrons predict an assortment of "exotic" hadrons that have structures that are more complex then the quark-antiquark mesons and three-quark baryons of the original quark-parton model. These include pentaquark baryons, the six-quark H-dibaryon, and tetra-quark, hybrid, and glueball mesons.

Scalar mesons and tetraquarks by means of lattice QCD [PDF]

, 2012
We study the light scalar mesons a_0(980) and kappa using N_f = 2+1+1 flavor lattice QCD. In order to probe the internal structure of these scalar mesons, and in particular to identify, whether a sizeable tetraquark component is present, we use a large ...

Methods to achieve near-millisecond energy relaxation and dephasing times for a superconducting transmon qubit

Nature Communications
Superconducting qubits are one of the most promising physical systems for implementing quantum computers. However, executing quantum algorithms of practical computational advantage requires further improvements in the fidelities of qubit operations ...

Electroweak corrections and shower effects to Higgs production in association with two jets at the LHC

Journal of High Energy Physics, 2022
We present an implementation of the full electroweak H + 2 jets production process at hadron colliders in the framework of the POWHEG BOX, a public tool for the matching of fixed-order perturbative calculations with parton shower generators.

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

RS-invariant resummations of QCD perturbation theory [PDF]

, 1997
We propose a renormalon-inspired resummation of QCD perturbation theory based on approximating the renormalization scheme (RS) invariant effective charge (EC) beta- function coefficients by the portion containing the highest power of b = (11N'-2N(_f))/6,
