Parafermionic and decoupled multicritical points in a frustrated clock chain
Andrea Kouta Dagnino, Attila Szabó
We introduce a generalised six-state clock chain that interpolates between the clock and Potts models via a multicritical point described by decoupled Ising and three-state Potts m…

How quantum fluctuations freeze a classical liquid and then melt it into a topological one
Hao Chen, Dan Mao, Andrea Kouta Dagnino +5
Topologically ordered quantum liquids are highly sought-after quantum phases of matter, and recently, fractional Chern insulators (FCIs) joined the few experimental realizations of…

The landscape of symmetry enhancement in tight-binding models
A. K. Dagnino, A. Corticelli, M. Gohlke +3
Band structures are ubiquitous in condensed matter physics and their symmetries constrain possible degeneracies, topology and response functions across a broad range of different s…
