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…
Quantum Gross-Pitaevskii Equation
Jutho Haegeman, Damian Draxler, Vid Stojevic +3
We introduce a non-commutative generalization of the Gross-Pitaevskii equation for one-dimensional quantum gasses and quantum liquids. This generalization is obtained by applying t…
Symmetry Breaking and the Geometry of Reduced Density Matrices
V. Zauner, D. Draxler, L. Vanderstraeten +2
The concept of symmetry breaking and the emergence of corresponding local order parameters constitute the pillars of modern day many body physics. The theory of quantum entanglemen…
Transfer Matrices and Excitations with Matrix Product States
V. Zauner, D. Draxler, L. Vanderstraeten +6
We investigate the relation between static correlation functions in the ground state of local quantum many-body Hamiltonians and the dispersion relations of the corresponding low e…
Particles, holes and solitons: a matrix product state approach
Damian Draxler, Jutho Haegeman, Tobias J. Osborne +3
We introduce a variational method for calculating dispersion relations of translation invariant (1+1)-dimensional quantum field theories. The method is based on continuous matrix p…
