Three-dimensional Foliated Fractional Quantum Hall Phases
Sahana Das, Navketan Batra, Andrea Kouta Dagnino +4
Foliated topological orders in three dimensions are layered systems in which anyons are free to move within a layer but cannot hop between them. A simple model with such a phase is…
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…
Non-linear transport in multifold semimetals
Andrea Kouta Dagnino, Xiaoxiong Liu, Titus Neupert
Transport measurements are a powerful way to probe the electronic structure of quantum materials, but the information they contain is often convoluted. Yet, in particular for simpl…
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…
When Could Abelian Fractional Topological Insulators Exist in Twisted MoTe (and Other Systems)
Yves H. Kwan, Glenn Wagner, Jiabin Yu +6
Using comprehensive exact diagonalization calculations on twisted bilayer MoTe (MoTe), as well as idealized Landau level models also relevant fo…
