Generalized Integrable Boundary States in XXZ and XYZ Spin Chains
Xin Qian, Xin Zhang
We investigate integrable boundary states in the anisotropic Heisenberg chain under periodic or twisted boundary conditions, for both even and odd system lengths. Our work demonstr…

The spectrum of defect ABJM theory
Charlotte Kristjansen, Xin Qian, Chenliang Su
We determine the spectrum of quantum fluctuations in a 1/2-BPS domain wall version of ABJM theory, thereby enabling the perturbative exploration of the corresponding defect CFT. As…

On exact overlaps of integrable matrix product states: inhomogeneities, twists and dressing formulas
Tamas Gombor, Charlotte Kristjansen, Vasileios Moustakis +1
Invoking a quantum dressing procedure as well as the representation theory of twisted Yangians we derive a number of summation formulas for the overlap between integrable matrix pr…
