Boundary criticality via gauging finite subgroups: a case study on the clock model
Lei Su
Gauging a finite Abelian normal subgroup of a nonanomalous 0-form symmetry of a theory in D spacetime can yield an unconventional critical point if the original theo…
Integrable nonunitary quantum circuits
Lei Su, Ivar Martin
We show that the integrable Lindblad superoperators found recently can be used to build integrable nonunitary quantum circuits with two-site gates by demonstrating that the $\check…
Charge Density Waves and the Hidden Nesting of Purple Bronze KMoO
Lei Su, Chuang-Han Hsu, Hsin Lin +1
We introduce the first multiorbital effective tight-binding model to describe the effect of electron-electron interactions in this system. Upon fixing all the effective hopping par…
Dimer-induced heavy-fermion superconductivity in the Shastry-Sutherland Kondo lattice model
Lei Su, Pinaki Sengupta
We study the Kondo lattice model on the geometrically frustrated Shastry-Sutherland lattice focusing on the quantum phase transition between the valence bond solid and the heavy fe…
Magnetic phases in the S=1 Shastry-Sutherland model with uniaxial anisotropy
Lei Su, Keola Wierschem, Pinaki Sengupta
We explore the field induced magnetic phases of an model with single-ion anisotropy and large Ising-like anisotropy on a Shastry Sutherland lattice over a wide range of…
