Twisted mass QCD at finite temperature [PDF]
, 2012 We discuss the use of Wilson fermions with twisted mass for simulations of QCD thermodynamics. As a prerequisite for a future analysis of the finite-temperature transition making use of automatic O(a) improvement, we investigate the phase structure in ...

Combining the complex Langevin method and the generalized Lefschetz-thimble method
Journal of High Energy Physics, 2017 The complex Langevin method and the generalized Lefschetz-thimble method are two closely related approaches to the sign problem, which are both based on complexification of the original dynamical variables. The former can be viewed as a generalization of

EcoMat, Volume 8, Issue 5, May 2026.This review highlights how nanomaterials with high adsorption capacities including carbon‐based structures, transition metal oxides, 2D layers, and zeolites enable sensitive and selective detection of toxic gases and VOCs. Their tailored properties and sensing mechanisms drive the development of next‐generation gas sensors for environmental and ...

Correlations among discontinuities in the QCD phase diagram [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2009 We show, in general, that when a discontinuity of either zeroth-order or first-order takes place in an order parameter such as the chiral condensate, discontinuities of the same order emerge in other order parameters such as the Polyakov loop. A condition for the coexistence theorem to be valid is clarified. Consequently, only when the condition breaks

The first second of leptons [PDF]
, 2011 Stuke M. The first second of leptons. Bielefeld (Germany): Bielefeld University; 2011.We study the influence of lepton asymmetries on the evolution of the early Universe. The lepton asymmetry l is poorly constrained by observations and might be orders of

QCD phase structure & equation of state: A functional perspective* [PDF]
EPJ Web of ConferencesThe phase structure of QCD remains an open fundamental problem of standard model physics. In particular at finite density, our knowledge is limited. Yet, numerous model studies point towards a rich and complex phase diagram at large density.

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'

Study of QCD-like theories at nonzero temperatures and densities [PDF]
, 2012 In this thesis I use effective models to investigate the properties of QCD-like theories at nonzero temperature and baryon chemical potential. First I construct a PNJL model using a lattice spin model with nearestneighbor interactions for the gauge ...

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.
