This paper uses a computational framework to analyse the equilibrium dynamics of exploitation and inequality in accumulation economies with heterogeneous labour. A novel index is presented which measures the intensity of exploitation at the individual level and the dynamics of the distribution...

Unlike linear ones, nonlinear business cycle models can generate sustained fluctuations even in the absence of shocks (e.g., via limit cycles/chaos). A popular approach to solving nonlinear models is perturbation methods. I show that, as typically implemented, these methods are incapable of...

In this paper, we present a new dynamic topic modeling method to build stable models and consistent time series. We call this new method RollingLDA. It has the potential to overcome several difficulties researchers, who use unsupervised probabilistic topic models, have grappled with: namely the...

Using the first-principles calculations based on density functional theory, we investigate the more d-electrons doping effects on the electronic structure and magnetism of the parent inverse Heusler alloy Ti<Subscript>2</Subscript>CoAl by the substitution of Nb and V atoms for Ti(A) and Ti(B) atoms locating at the two...</subscript>

First-principles calculations based on density functional theory within the general gradient approximation (GGA) are performed to study the electronic structure and magnetic properties of Pd doped ZnS. It is found that an isolated Pd atom doped 2 × 2 × 2 ZnS supercell shows half-metallic...

It is virtually impossible to evaluate the magnetic properties of large anisotropic magnetic molecules numerically exactly due to the huge Hilbert space dimensions as well as due to the absence of symmetries. Here we propose to advance the finite-temperature Lanczos method (FTLM) to the case of...

We study the effect of multiple interpenetrating pinning arrays on the vortex motion in the presence of an ac driving force, f <Subscript> d </Subscript>(t), by using extensive molecular dynamics (MD) simulations. Firstly, the response to a square ac wave f <Subscript> d </Subscript>(t) has been explored for the vortices interacting with a...</subscript></subscript>
