Mixed spectra and partially extended states in a two-dimensional quasiperiodic model
Attila Szabó, Ulrich Schneider
We introduce a two-dimensional generalisation of the quasiperiodic Aubry-André model. Even though this model exhibits the same duality relation as the one-dimensional version, its…

Generalised route to effective field theories for quantum systems with local constraints
Attila Szabó, Garry Goldstein, Claudio Castelnovo +1
Some of the exciting phenomena uncovered in strongly correlated systems in recent years - for instance quantum topological order, deconfined quantum criticality, and emergent gauge…

Seeing beyond the light: Vison and photon electrodynamics in quantum spin ice
Attila Szabó, Claudio Castelnovo
Understanding the nature and behaviour of excitations in quantum spin liquids, and in topological phases of matter in general, is of fundamental importance and has proven crucial f…
