Nonrelativistic versus relativistic quantum scars in billiard systems
Barbara Dietz, Dung Xuan Nguyen, Tilen Čadež
We study the features of scarred eigenstates of relativistic neutrino billiards (NBs), graphene billiards (GBs) and Haldane graphene billiards (HGBs) and recapitulate those for non…
Dynamics and lifetime of geometric excitations in moiré systems
Yuzhu Wang, Joe Huxford, Dung Xuan Nguyen +3
We show that spin-2 geometric excitations, known as graviton modes, generally exhibit vanishing lifetimes in lattice Chern bands, including in moiré systems. In contrast to the Lan…
Haldane graphene billiards versus relativistic neutrino billiards
Dung Xuan Nguyen, Barbara Dietz
We study fluctuation properties in the energy spectra of finite-size honeycomb lattices, graphene billiards, subject to the Haldane-model onsite potential and next-nearest neighbor…
Twisted Lattice Gauge Theory: Membrane Operators, Three-loop Braiding and Topological Charge
Joe Huxford, Dung Xuan Nguyen, Yong Baek Kim
3+1 dimensional topological phases can support loop-like excitations in addition to point-like ones, allowing for non-trivial loop-loop and point-loop braiding statistics not permi…
