Focusing on two-level atoms, we apply the positive P representation to a full-wave mixed bosonic and fermionic system of Jaynes-Cummings type and identify an advantageous degree of freedom in the choice of the involved nonorthogonal fermionic basis states. On this basis, we propose a stochastic correction to the Maxwell-Bloch equations by relating them to a stochastic differential equation on a nonclassical phase space, which captures the full second quantization dynamics of the system.

AbstractWe study a hypoplastic model for soil and granular materials stemming from geomechanical engineering which further incorporates effects of degradation of the granular hardness, therefore allowing for the description of environmental weathering. The governing system is described by a nonlinear system of transcendental-differential equations for stress and strain rate, which is investigated with respect to its long-time dynamic.

The first use case in this study represents the capability of the described workflow to create high-confidence and comprehensive consensus sequences from repetitive elements. Here, we use available data from the recently sequenced Beta corolliflora, a wild beet species and close relative of the crop plant sugar beet (Beta vulgaris). The consensus sequences have been assembled after clustering of the read data with RE2 [16].
