Title: | Algebraic geometry of tree tensor networks |

Seminar: | Applied Algebra and Network Theory Seminar |

Speaker: | Sara Jamshidi, Penn State |

Abstract: |

Tree tensor networks have been used to model the ground states of Hamiltonians in condensed matter physics and quantum chemistry. Exactly which quantum states can be represented by a tree tensor network with a given topology and given restrictions on the parameter tensors? When the restrictions are algebraic, the set of states is a projective algebraic variety. We describe those varieties, using techniques originally developed for phylogenetics. |
