Emerging network model in a twisted monolayer-rhombohedral graphene
Juyoung Song, Jeyong Park, Jinhong Park
We investigate the coexistence of localized states and propagating one-dimensional (1D) modes in graphene moiré systems. We first show within a minimal model that a spatially varyi…
Observation of Time-Domain Braiding of Non-Abelian Anyons at State
Tomer Alkalay, Jinhong Park, Minseong Oh +7
Unlike elementary particles, which obey either bosonic or fermionic exchange statistics, certain quasiparticles, known as anyons, are predicted to exhibit Abelian or non-Abelian br…
Network of chiral one-dimensional channels and localized states emerging in a moiré system
Jeyong Park, Lasse Gresista, Simon Trebst +2
Moiré systems provide a highly tunable platform for engineering band structures and exotic correlated phases. Here, we theoretically study a model for a single layer of graphene su…
Nonlinear transport due to magnetic-field-induced flat bands in the nodal-line semimetal ZrTe5
Yongjian Wang, Thomas Boemerich, Jinhong Park +4
The Dirac material ZrTe at very low carrier density was recently found to be a nodal-line semimetal, where ultra-flat bands are expected to emerge in magnetic fields parallel t…

In one-dimensional topological superconductors driven periodically with the frequency , two types of topological edge modes may appear, the well-known Majorana zero mode and a F…
Thermal Hall response: violation of gravitational analogues and Einstein relations
Jinhong Park, Omri Golan, Yuval Vinkler-Aviv +1
The response of solids to temperature gradients is often described in terms of a gravitational analogue: the effect of a space-dependent temperature is modeled using a space depend…
Absent thermal equilibration on fractional quantum Hall edges over macroscopic scale
Ron Aharon Melcer, Bivas Dutta, Christian Spånslätt +3
Two-dimensional topological insulators, and in particular quantum Hall states, are characterized by an insulating bulk and a conducting edge. Fractional states may host both downst…

Moiré materials provide a highly tunable environment for the realization of band structures with engineered physical properties. Specifically, moiré structures with Fermi surface f…

The recent measurement of a half-integer thermal conductance for the fractional quantum Hall state has confirmed its non-Abelian nature, making the question of the underlyi…
Energy relaxation in edge modes in the quantum Hall effect
Amir Rosenblatt, Sofia Konyzheva, Fabien Lafont +6
Studies of energy flow in quantum systems complement the information provided by common conductance measurements. The quantum limit of heat flow in one dimensional (1D) ballistic m…
Symmetry-related transport on a fractional quantum Hall edge
Jinhong Park, Bernd Rosenow, Yuval Gefen
Low-energy transport in quantum Hall states is carried through edge modes, and is dictated by bulk topological invariants and possibly microscopic Boltzmann kinetics at the edge. H…
