Private Types
typedef std::unordered_map< Rep, Vec< Rep > >	PhysTable
	For each key SU(2) `Rep` we get a vector telling us which element inside dense tensors belongs to which U(1) `Rep`. More...

	Same but for virtual indices. More...

Private Member Functions
Tensor< 3 >	back_cast (Tensor< 3 > const &m)
	Casts SU(2)xU(1) tensor back to unprotected tensor and updates the table. More...

Tensor< 3 >	cast (Tensor< 3 > mat) const
	Casts the SU(2) protected first site. More...

Tensor< 4 >	cast (Tensor< 4 > mat) const
	Casts the SU(2) protected pseudo matrix. More...

Tensor< 4 >	compute_pseudo_matrix () const
	Computes the rank 4 matrix for the current site. More...

void	contr_right (Tensor< 3 > const &updated)
	Computes new right contraction. More...

Tensor< 3 >	decompose (Tensor< 4 > const &m) const
	Decomposes the rank 4 tensor into two rank 3 tensors. More...

Private Attributes
State	br
	MPS consisting of back casted unitaries. More...

Index	current
	Current position. More...

Vec< Tensor< 2 > >	l_contr
	Left contractions. More...

Index const	length
	Size of MPS. More...

PhysTable	phys_tab
	Mapping between physical bonds. More...

State	r
	The new SU(2) x U(1) state which is going to be constructed. More...

Tensor< 4 >	r_contr
	Right contraction. More...

State const &	state
	The original SU(2) state. More...

Index const	target
	Target particle number. More...
