Critical properties of quantum three- and four-state Potts models with boundaries polarized along the transverse field
Natalia Chepiga
By computing the low-lying energy excitation spectra with the density matrix renormalization group algorithm we show that boundaries polarized in the direction of the transverse fi…

Supersymmetry and multicriticality in a ladder of constrained fermions
Natalia Chepiga, Jiří Minář, Kareljan Schoutens
Supersymmetric lattice models of constrained fermions are known to feature exotic phenomena such as superfrustration, with an extensive degeneracy of ground states, the nature of w…

Lifshitz point at commensurate melting of 1D Rydberg atoms
Natalia Chepiga, Frédéric Mila
The recent investigation of chains of Rydberg atoms has brought back the problem of commensurate-incommensurate transitions into the focus of current research. In 2D classical syst…
