We develop a consistent theory of the interlayer exciton-polaron formed in atomically thin bilayers. Coulomb attraction between an electron and hole situated different layers results their flexural deformation provides efficient mechanism exciton coupling with phonons. study effect tension on polaron binding energy effective mass leading to suppression formation by both weak strong regimes. als...

The main goal of the present paper is to analyze the effects of currency collapses (a large devaluation of country’s nominal exchange rate) on real gross domestic products of six Asian countries (Iran, Indonesia, Malaysia, Pakistan, South Korea, and Turkey). A yearly data is collected from the WDI of the World Bank over the period 1980-2011. The econometric model includes the real GDP growt...

We study episodes where economic growth decelerates to negative rates. While the majority of these episodes are of short duration, a substantial fraction last for a longer period of time than can be explained as the result of businesscycle dynamics. The duration, depth and associated output loss of these episodes differs dramatically across regions. We investigate the factors associated with th...
