Phase structure of lattice QCD at finite temperature for 2+1 flavors of Kogut-Susskind quarks [PDF]

, 1998
We report on a study of the finite-temperature chiral transition on an $N_t=4$ lattice for 2+1 flavors of Kogut-Susskind quarks. We find the point of physical quark masses to lie in the region of crossover, in agreement with results of previous studies ...

Dynamical correlations in multiorbital Hubbard models: Fluctuation-exchange approximations [PDF]

, 2004
We study the two band degenerate Hubbard model using the Fluctuation Exchange approximation (FLEX) method and compare the results with Quantum Monte-Carlo calculations.

Nontrivial critical crossover between directed percolation models: Effect of infinitely many absorbing states

, 2007
At non-equilibrium phase transitions into absorbing (trapped) states, it is well known that the directed percolation (DP) critical scaling is shared by two classes of models with a single (S) absorbing state and with infinitely many (IM) absorbing states.

Thermodynamic properties and bulk viscosity near phase transition in the Z(2) and O(4) models

, 2009
We investigate the thermodynamic properties including equation of state, the trace anomaly, the sound velocity and the specific heat, as well as transport properties like bulk viscosity in the Z(2) and O(4) models in the Hartree approximation of Cornwall-

Correlated electron transport through double quantum dots coupled to normal and superconducting leads

, 2010
We study Andreev transport through double quantum dots connected in series normal and superconducting (SC) leads, using the numerical renormalization group.

Healing of Defects in Random Antiferromagnetic Spin Chains

, 2017
We study the effects of a weakened link in random antiferromagnetic spin chains. We show that healing occurs, and that homogeneity is restored at low energy, in a way that is qualitatively similar to the fate of impurities in clean ferromagnetic spin ...

Cause-specific cardiovascular disease mortality attributable to ambient temperature: A time-stratified case-crossover study in Jiangsu province, China

Ecotoxicology and Environmental Safety, 2022
Background: Exposure to non-optimum ambient temperature has been linked to increased risk of total cardiovascular disease (CVD) mortality; however, the adverse effects on mortality from specific types of CVD remain less understood.

Energy loss in a strongly coupled anisotropic plasma

, 2012
We study the energy loss of a rotating infinitely massive quark moving, at constant velocity, through an anisotropic strongly-coupled N=4 plasma from holography.

The heterogeneity of mortality burden of lower respiratory infection associated with ambient temperature and its drivers in China

Ecotoxicology and Environmental Safety
：: Ambient temperature is linked to an increased risk of lower respiratory infections (LRI) yet the evidence on the population and spatial heterogeneity of LRI mortality burden attributed to non-optimal temperatures and its socioeconomic drivers remain ...
