    Abstract: A non-transitory machine readable storage medium having a machine readable program stored therein, wherein the machine readable program, when executed on a processing system, causes the processing system to perform a method of modeling a many particle system, wherein the method includes determining a compensation function, wherein the compensation function compensates errors introduced by an approximation of at least one of a plurality of interaction equations applied on the plurality of interaction equations, wherein the plurality of interaction equations includes the approximation. The method additionally includes solving at least a system of the many particle system without the plurality of interaction equations to extract an uncompensated solution of the many particle system. Additionally, the method includes solving the many particle system with the plurality of interaction equations by a first iteration to extract a plurality of observables in the many particle system, wherein the first iteration includes

    Abstract: A method of determining a property of a liquid system, the liquid system including at least one molecule in a solvent, comprises: generating a quantum model of the liquid system, the quantum model including a device region and a lead region, the device region being spherical, paraboloid, cubic or arbitrary in shape and encompassing the at least one molecule and a portion of the solvent of the liquid system, the lead region encompassing a region of the solvent surrounding the device region, determining a first property of the device region by solving a first quantum equation for the device region, determining the first property of the lead region by solving the first quantum equation under open boundary conditions for the lead region, and combining the first property of the device region with the first property of the lead region to arrive at a total first property for the liquid system.

    Abstract: The disclosure develops a multi-scale model that partitions the device into different spatial regions where the high carrier domains are treated as reservoirs in local equilibrium and serve as injectors and receptors of carriers into the neighboring reservoirs through tunneling and thermionic emission. The nonequilibrium Green's function (NEGF) formalism is used to compute the dynamics (states) and the kinetics (filling of states) in the entire extended complex device. The local density of states in the whole device is computed quantum mechanically within a multi-band tight binding Hamiltonian. The model results agree with experimental I-V curves quantitatively.
