Death and immortality played a central role in Greek and Roman thought, from Homer and early Greek philosophy to Marcus Aurelius. In this book A. G. Long explains the significance of death and immortality in ancient ethics, particularly Plato's dialogues, Stoicism and Epicureanism; he also shows how philosophical cosmology and theology caused immortality to be re-imagined. Ancient arguments and theories are related both to the original literary and theological contexts and to contemporary debates on the philosophy of death. The book will be of major interest to scholars and students working on Greek and Roman philosophy, and to those wishing to explore ancient precursors of contemporary debates about death and its outcomes.
This work is based on a recent theoretical study of how the hydrostatic pressure and core/shell sizes affect the optical properties associated with the transition from the ground state to first excited state (1s–1p), of an exciton confined in spherical core/shell quantum dots (SCSQDs). We have computed under an effective mass framework, linear, third-order nonlinear, and total absorption coefficients (AC) and refractive index (RI) as functions of photon energy for different sizes of SCSQDs with varying hydrostatic pressure. Our results show that the optical absorption is deeply dependent on the incident light intensity. Both AC and RI significantly influenced by the confinement and pressure effects.
