New PDF release: Advances in Sensing with Security Applications: Proceedings

By Alexander A. Nepomnyashchy (auth.), Alexander A. Golovin, Alexander A. Nepomnyashchy (eds.)

Nano-science and nano-technology are quickly constructing medical and technological parts that take care of actual, chemical and organic tactics that take place on nano-meter scale – one millionth of a millimeter. Self-organization and trend formation play an important function on nano-scales and promise new, potent routes to regulate a number of nano-scales strategies. This publication includes lecture notes written by way of the academics of the NATO complex learn Institute "Self-Assembly, development Formation and development Phenomena in Nano-Systems" that happened in St Etienne de Tinee, France, within the fall 2004. they offer examples of self-organization phenomena on micro- and nano-scale in addition to examples of the interaction among phenomena on nano- and macro-scales resulting in advanced habit in numerous actual, chemical and organic structures. They speak about such interesting nano-scale self-organization phenomena as self-assembly of quantum dots in skinny good motion pictures, trend formation in liquid crystals as a result of gentle, self-organization of micro-tubules and molecular cars, in addition to simple actual and chemical phenomena that result in self-assembly of an important molecule at the foundation of which such a lot of residing organisms are outfitted – DNA. A evaluate of normal gains of all trend forming platforms is usually given. The authors of those lecture notes are the top specialists within the box of self-organization, trend formation and nonlinear dynamics in non-equilibrium, complicated systems.

Example text

For the sake of simplicity, choose X0 = 0. Taking into account the relations (72), we find that the corresponding orderparameter field is √ 1 φ1 = Aeix0 + A∗ e−ix0 = 2 3 1 − K 2 cos x0 + Kx1 2 1 = 2 3(1 − K 2 ) cos 1 + K x . 2 Thus, these solutions correspond to roll solutions with wavenumbers k = 1 + K /2, −1 < K < 1 (78) inside the instability interval, generally different from 1. Let us investigate the stability of roll solutions in the framework of the NWS equation. Linearizing equation (73) around the solution (77), we obtain the following equation: d˜ a = −(1 − 2K 2 )˜ a − (1 − K 2 )˜ a∗ e2iKX + dT 2 i ∂2 ∂ − ∂X 2 ∂Y 2 a ˜.

98) In order to consider rolls of different orientations, we take N An (T, r1 )eikn ·r0 + A∗n (T, r1 )e−ikn ·r0 , φ1 = (99) n=1 where |kn | = 1. The ansatz (99) resembles (21), but there is an essential difference: now the functions An depend on the slow coordinate r1 . Therefore we can consider different roll patterns localized in different regions rather than uniformly superposed. 32 PATTERN FORMATION IN NANO-SYSTEMS At order O( 3 ), we obtain the following generalization of equations (23): ∂An = (1 − 3|An |2 − 6 ∂T |Am |2 )An + 4(kn · ∇1 )2 An , n = 1, .

As in the previous section, we shall use the scaled time variable T = 2 t. , [45]), we substitute ∂ ∂ ∂ ∂ = = + , ∂x ∂x0 ∂x1 ∂y 1/2 ∂ ∂ = , ∂y1/2 ∂t 2 ∂ ∂T into (17) and obtain: 2 ∂φ = ∂T 2 ∂2 φ− 1+ 2 + ∂x0 ∂2 ∂2 2 + 2 ∂x0 ∂x1 ∂y1/2 + 2 ∂2 ∂x21 2 φ − φ3 . (65) Now we substitute the solution in the form φ = φ1 + 2 φ2 + 3 φ3 + . . , (66) and demand boundness with respect to all the variables at each order. At order , we obtain: − 1+ ∂2 ∂x20 2 φ1 = 0. (67) The most general bounded solution of this equation, φ1 = A(T, x1 , y1/2 )eix0 + A∗ (T, x1 , y1/2 )e−ix0 , (68) 24 PATTERN FORMATION IN NANO-SYSTEMS k y perfect rolls with |k|=1 1/2 Ο(ε ) suppressed by Ο(ε) nonlinear competition kx modulations Figure 11.
