Chirality2D

class Chirality2D : public feasst::Analyze

Compute the 2D chirality by analyzing the sign of the cross product between two bonds.

Public Functions

std::string header(const MonteCarlo &mc) const

Return the header for writing.

void initialize(MonteCarlo *mc)

Initialize and precompute before trials.

void update(const MonteCarlo &mc)

Perform update action.

std::string write(const MonteCarlo &mc)

Perform write action.

const Accumulator &num_positive() const

Return the average number of chiral positive particles.

Arguments

  • group: group index in Configuration (default: 0).

  • bond1: index of the first bond (default: 0).

  • bond2: index of the second bond (default: 1).

  • sign_error: error if chirality of sign and != 0 (default 0).

  • Stepper arguments.
