Eigenvector Varieties

Sandra Di Rocco, Bernd Sturmfels, Svala SverrisdÃ³ttir +1

Any linear space of square matrices has an associated eigenvector variety. Its points are eigenvectors of matrices from that linear space. We present a systematic study of eigenvec…

Gram Matrices for Isotropic Vectors

Yassine El Maazouz, Bernd Sturmfels, Svala SverrisdÃ³ttir

We investigate determinantal varieties for symmetric matrices that have zero blocks along the main diagonal. In theoretical physics, these arise as Gram matrices for kinematic vari…

Algebraic Geometry for Spin-Adapted Coupled Cluster Theory

Fabian M. Faulstich, Svala SverrisdÃ³ttir

We develop and numerically analyze an algebraic-geometric framework for spin-adapted coupled-cluster (CC) theory. Since the electronic Hamiltonian is SU(2)-invariant, physically re…

Plane partitions and spin adapted quantum states

Abigail Price, Ada Stelzer, Svala SverrisdÃ³ttir

We describe an explicit basis for the $SU (2)$ -invariant space of the exterior power $\land_{2 k} C^{2 m}$ via the combinatorics of plane partitions. In quant…

Algebraic Varieties in Second Quantization

Svala SverrisdÃ³ttir

We develop an algebraic geometric framework for Fock space coupled cluster theory in second quantization. In quantum chemistry, many-electron states are represented as elements of…

Kinematic Varieties for Massless Particles

Smita Rajan, Svala SverrisdÃ³ttir, Bernd Sturmfels

We study algebraic varieties that encode the kinematic data for $n$ massless particles in $d$ -dimensional spacetime subject to momentum conservation. Their coordinates are spinor b…
