Entanglement cohomology for GHZ and W states

Christian Ferko, Keiichiro Furuya

Entanglement cohomology assigns a graded cohomology ring to a multipartite pure state, providing homological invariants that are stable under local unitaries and characterize inequ…

Soliton Surfaces and the Geometry of Integrable Deformations of the $CP^{N - 1}$ Model

Christian Ferko, Michele Galli, Zejun Huang +1

The $CP^{N - 1}$ model is an analytically tractable $2 d$ quantum field theory which shares several properties with $4 d$ Yang-Mills theory. By virtue of its classical integra…

Higher-Spin Currents and Flows in Auxiliary Field Sigma Models

Daniele Bielli, Christian Ferko, Michele Galli +1

We study local, higher-spin conserved currents in integrable $2 d$ sigma models that have been deformed via coupling to auxiliary fields. These currents generate integrability-prese…
