Exact Rokhsar-Kivelson points hosting first-order phase transitions in compass models
Jay Pandey
We study compass models on the square and kagome lattices with bond-dependent bilinear and biquadratic interactions parametrized by an angle . For compatible geometries, w…
Confinement-deconfinement transitions in the dimer-loop models on two-dimensional non-bipartite lattices
Jay Pandey, Souvik Kundu, Kedar Damle
Recent work [Kundu, Damle, Phys. Rev. X 15, 011018 (2025)] has demonstrated that a class of kagome lattice antiferromagnets with competing anisotropies can exhibit unusual lo…
Multi-invariants in stabilizer states
Sriram Akella, Abhijit Gadde, Jay Pandey
Multipartite entanglement is a natural generalization of bipartite entanglement, but is relatively poorly understood. In this paper, we develop tools to calculate a class of multip…
pyrochlore magnets with competing anisotropies: A tale of two Coulomb phases, flux confinement and -like transitions
Jay Pandey, Kedar Damle
We argue that the low-temperature physics of pyrochlore magnets with a predominantly Ising-like easy-axis exchange coupling that favors the local tetrahedral body diagona…
