Class WaveVectorFactory1D

java.lang.Object

etomica.normalmode.WaveVectorFactory1D

All Implemented Interfaces:

WaveVectorFactory, java.io.Serializable

public class WaveVectorFactory1D
extends java.lang.Object
implements WaveVectorFactory, java.io.Serializable

Wave vector factory that returns wave vectors for a 1D system. These wave vectors are given by 2 Pi m / (N a) = 2 Pi m / L = 2 Pi m rho / N, for m = 1, 2, 3,...,N/2. If N is odd there will be (N-1)/2 vectors, each with a coefficient of 1.0 (because none are on the Brillouin-zone boundary) while if N is even there will be N/2, with the last one having a coefficient of 0.5. Wave vectors corresponding to m <= 0 are not included, although they are technically are among the full set of wave vectors for the system.

Method Detail

makeWaveVectors

public void makeWaveVectors(Box box)

Description copied from interface: WaveVectorFactory

Tells the instance to make wave vectors appropriate for the given box. The wave vectors will not include the 0 vector, any two vectors which are opposites or any wave vector that is redundant with another.

Specified by:

makeWaveVectors in interface WaveVectorFactory

getWaveVectors

public Vector[] getWaveVectors()

Description copied from interface: WaveVectorFactory

Returns the wave vectors generated by makeWaveVectors

Specified by:

getWaveVectors in interface WaveVectorFactory

getCoefficients

public double[] getCoefficients()

Description copied from interface: WaveVectorFactory

Returns the coefficients for the wave vectors returned by getWaveVectors. If two of the wave vectors are redundant, their coefficient will be 0.5. Others will have a coefficient of 1.0.
