We investigate the possibility to assist the numerically ill-posed calculation of spectral properties of interacting quantum systems in thermal equilibrium by extending the imaginary-time simulation to a finite Schwinger-Keldysh contour. The effect of this extension is tested within the standard maximum entropy approach to analytic continuation. We find that the inclusion of real-time data impr...

A comparison of full quantum device simulation with semi-classical methods is made for an unintended single atomistic dopant at various locations in a 10 nm double gate MOSFET transistor. The density gradient method comes closest to the non-equilibrium Green function results for fails seriously when the unwanted charge is located well-within the channel.

Synopsis : The transient network model of Green-Tobolsky [1946], Yamamoto [1956] and Tanaka-Edwards [1992] is formulated within the frame of thermodynamics of irreversible processes, using as a fundamental quantity the chemical potential associated to the connection of strands to the network and treating these connections as chemical-like reactions. All thermodynamic quantities are thus natural...

This paper explores the effect of exclusionary ”ethical investing” on corporate behavior in a risk averse, equilibrium setting. While arguments exist that ethical investing can inßuence a Þrm’s cost of capital, and so affect investment, no equilibrium model has been presented to do so. We show that exclusionary ethical investing leads to ”polluting” Þrms being held by fewer investors since ”gre...
