Continuous matrix product states with periodic boundary conditions and an application to atomtronics
Damian Draxler, Jutho Haegeman, Frank Verstraete +1
We introduce a time evolution algorithm for one-dimensional quantum field theories with periodic boundary conditions. This is done by applying the Dirac-Frenkel time-dependent vari…
Fermionic Matrix Product Operators and Topological Phases of Matter
Dominic J. Williamson, Nick Bultinck, Jutho Haegeman +1
We introduce the concept of fermionic matrix product operators, and show that they provide a natural representation of fermionic fusion tensor categories. This allows for the class…
Matrix Product Density Operators: Renormalization Fixed Points and Boundary Theories
J. I. Cirac, D. Perez-Garcia, N. Schuch +1
We consider the tensors generating matrix product states and density operators in a spin chain. For pure states, we revise the renormalization procedure introduced by F. Verstraete…
