Chaos and energy spreading for time-Dependent Hamiltonians, and the various Regimes in the theory of Quantum Dissipation

, 2000
We make the first steps towards a generic theory for energy spreading and quantum dissipation. The Wall formula for the calculation of friction in nuclear physics and the Drude formula for the calculation of conductivity in mesoscopic physics can be ...

Widowhood disparities in nonaccidental mortality attributable to heat waves and ozone

Eco-Environment & Health
Emerging evidence suggests that heat waves and ozone (O3) contribute to increased mortality risks. Since widowhood is a common event that can increase individuals' susceptibility to the environment, it is of great importance and interest to elucidate the

Relativistic BCS-BEC crossover in a boson-fermion model [PDF]

, 2006
We investigate the crossover from Bardeen-Cooper-Schrieffer (BCS) pairing to a Bose-Einstein condensate (BEC) in a relativistic superfluid within a boson-fermion model.

Nonequilibrium characteristics in all-superconducting tunnel structures

, 2006
We study the nonequilibrium characteristics of superconducting tunnel structures in the case when one of the superconductors is a small island confined between large superconductors. The state of this island can be probed for example via the supercurrent

High-Temperature Atomic Superfluidity in Lattice Boson-Fermion Mixtures [PDF]

, 2004
We consider atomic Bose-Fermi mixtures in optical lattices and study the superfluidity of fermionic atoms due to s-wave pairing induced by boson-fermion interactions.

Differentiating the impact of non-optimum temperature and temperature variability on cause-specific cerebrovascular mortality: An individual-level, case-crossover study in Shanghai, China

Ecotoxicology and Environmental Safety
Background: Cerebrovascular mortality exhibits seasonal variation, but the roles of temperature and temperature variability (TV) in cause-specific cerebrovascular mortality remain unclear.

Number fluctuations in cold quantum gases

, 2007
In ultracold gases many experiments use atom imaging as a basic observable. The resulting image is averaged over a number of realizations and mostly only this average is used. Only recently the noise has been measured to extract physical information.

Indirect forces between impurities in one-dimensional quantum liquids

, 2007
We investigate the indirect interaction between two isolated impurities in a Luttinger liquid described by a microscopic lattice model. To treat the electron-electron interaction U the functional renormalization group method is used.

Secondary phi meson peak as an indicator of QCD phase transition in ultrarelativistic heavy ion collisions [PDF]

, 1994
In a previous paper, we have shown that a double phi peak structure appears in the dilepton invariant mass spectrum if a first order QCD phase transition occurs in ultrarelativistic heavy ion collisions.

Differentiating the impact of fine and coarse particulate matter on cause-specific cerebrovascular mortality: An individual-level, case-crossover study

Ecotoxicology and Environmental Safety
Background and objectives: Many studies suggested that short-term exposure to fine particulate matter (PM2.5) and coarse particulate matter (PM2.5–10) was linked to elevated risk of cerebrovascular disease.
