A phonon laser in ultra-cold matter
, 2009 We show the possible excitation of a phonon laser instability in an ultra-cold atomic gas confined in a magneto-optical trap. Such an effect results from a negative Landau damping of the collective density perturbations in the gas, leading to the ...

Real effects of greenhouse gas disclosures
China Journal of Accounting ResearchThis study investigates the valuation and real effects of the mandatory disclosure of greenhouse gas (GHG) emission costs from the perspective of “double materiality.” We consider a firm with a Cobb-Douglas production function that combines GHG-related ...

Acceleration of Gas Reservoir Simulation Using Proper Orthogonal Decomposition
Geofluids, 2018 High-precision and high-speed reservoir simulation is important in engineering. Proper orthogonal decomposition (POD) is introduced to accelerate the reservoir simulation of gas flow in single-continuum porous media via establishing a reduced-order model

Dynamical properties of dipolar Fermi gases
, 2008 We investigate dynamical properties of a one-component Fermi gas with dipole-dipole interaction between particles. Using a variational function based on the Thomas-Fermi density distribution in phase space representation, the total energy is described by
