Self-motility of an active particle induced by correlations in the surrounding solution

Autor: Domínguez, Alvaro, Popescu, M. N., Rohwer, C. M., Dietrich, S.

Publikováno v: Physical Review Letters 125, 268002 (2020)

Current models of phoretic transport rely on molecular forces creating a "diffuse" particle-fluid interface. We investigate theoretically an alternative mechanism, in which a diffuse interface emerges solely due to a non-vanishing correlation length

Stresses in non-equilibrium fluids: Exact formulation and coarse grained theory

Autor: Krüger, M., Solon, A., Démery, V., Rohwer, C. M., Dean, D. S.

Starting from the stochastic equation for the density operator, we formulate the exact (instantaneous) stress tensor for interacting Brownian particles, whose average value agrees with expressions derived previously. We analyze the relation between t

Noncommutative quantum mechanics -- a perspective on structure and spatial extent

Autor: Rohwer, C M, Zloshchastiev, K G, Gouba, L, Scholtz, F G

Publikováno v: J.Phys.A43:345302,2010

We explore the notion of spatial extent and structure, already alluded to in earlier literature, within the formulation of quantum mechanics on the noncommutative plane. Introducing the notion of average position and its measurement, we find two equi

The output distribution of important LULU-operators

Autor: Anguelov, R., Butler, P. W., Rohwer, C. H., Wild, M.

Two procedures to compute the output distribution phi_S of certain stack filters S (so called erosion-dilation cascades) are given. One rests on the disjunctive normal form of S and also yields the rank selection probabilities. The other is based on

Formulation, Interpretation and Application of non-Commutative Quantum Mechanics

Autor: Scholtz, F G, Gouba, L, Hafver, A, Rohwer, C M

Publikováno v: J.Phys.A42:175303,2009

In analogy with conventional quantum mechanics, non-commutative quantum mechanics is formulated as a quantum system on the Hilbert space of Hilbert-Schmidt operators acting on non-commutative configuration space. It is argued that the standard quantu
