We propose a new generalization of the Yang-Baxter equation, where the
R-matrix depends on cluster Tex-variables in addition to the spectral
parameters. We point out that we can construct solutions to this new equation
from the recently-found corr...

We introduce a class of new integrable lattice models labeled by a pair of
positive integers N and r. The integrable model is obtained from the Gauge/YBE
correspondence, which states the equivalence of the 4d N=1 S^1 \times S^3/Z_r
index of a larg...

procedure. We provide two examples where this newly-introduced entanglement is

The number of BPS bound states of D-branes on a Calabi-Yau manifold depends on two sets of data, the BPS charges and the stability conditions. For D0 and D2-branes bound to a single D6-brane wrapping a Calabi-Yau 3-fold X, both are naturally relat...
