Functions
void	syten::MPS::SwappableTEBD::exponentiate_and_multiply (std::vector< HamiltonianSummand > const &summands, Lattice const &lat, SDef const &time_step, std::vector< Pair< Index, Index > > const &fermions, std::vector< MPS::Operator > &evolution_operators)
	Given a list of summands, exponentiates each and multiplies them up as specified into the evolution_operators vector. More...
Operator	syten::MPS::SwappableTEBD::exponentiate_factor_mpo (Index const i, Index const j, Operator op, SDef c, Lattice const &lat, std::vector< Pair< Index, Index > > const &fermions)
	Calculates exp(x*c*h) assuming that h only acts nontrivially on sites i and j and 'x' is '-i' for complex-valued compilations and '-1' for real-valued computations. More...
EvolutionPair	syten::MPS::SwappableTEBD::exponentiate_mpo_tensors (Tensor< 4 > const &left, Tensor< 4 > const &right, SDef const &c, Basis const &full_left_basis, Basis const &full_right_basis)
	Exponentiates two MPO tensors. More...
Tensor< 6 >	syten::MPS::SwappableTEBD::exponentiate_rank6_tensor (Tensor< 6 > const &t6, SDef const &c, Basis const &full_left_basis, Basis const &full_right_basis)
	Exponentiates a rank-6 tensor with legs: | 5 6 | v v | 1 <-[ ]<- 2 | v v | 3 4. More...
template<typename Iter >
Operator	syten::MPS::SwappableTEBD::multiply_factors (Iter begin, Iter end)
	Multiplies operators in the range [begin, end) together using a logarithmic recursive scheme. More...
std::vector< HamiltonianSummand >	syten::MPS::SwappableTEBD::parse_terms_file (std::string const &file, Lattice const &lat)
	Parses a file containing lines of the form A i j <MPO exp> where A is an arbitrary single-character tag, i and j are site indices and the MPO expression only acts nontrivially on those site indices. More...
EvolutionPair	syten::MPS::SwappableTEBD::split_rank6_into_mpos (Tensor< 6 > const &in)
	Splits a rank-6 tensor with legs: | 5 6 | v v | 1 <-[ ]<- 2 | v v | 3 4. More...
