Van Hove singularity-driven giant Nernst signal in twisted double bilayer graphene
Ujjal Roy, Monosij Roy, Unmesh Ghorai +8
Twisted graphene layers host van Hove singularities (vHSs), peaks in the electronic density of states, thought to drive exotic phases in moiré materials, but their effect on therma…
Selective braiding of different anyons in the even-denominator fractional quantum Hall effect
Jehyun Kim, Amit Shaer, Ravi Kumar +6
Even-denominator quantum Hall states can host several types of anyons with distinct exchange statistics. Depending on the anyon type, exchanging two quasiparticles can impart a pha…
Orbitally tuned composite-fermion metal-to-superfluid transitions
Ravi Kumar, Tomer Firon, André Haug +6
The effective interaction between composite fermions, set entirely by the Coulomb potential and the underlying electronic Landau level orbitals, can stabilize exotic fractional qua…
Interaction-driven quantum phase transitions between topological and crystalline orders of electrons
André Haug, Ravi Kumar, Tomer Firon +5
Topological and crystalline orders of electrons both benefit from enhanced Coulomb interactions in partially filled Landau levels. In bilayer graphene (BLG), the competition betwee…
Aharonov-Bohm Interference in Even-Denominator Fractional Quantum Hall States
Jehyun Kim, Himanshu Dev, Amit Shaer +9
Position exchange of non-Abelian anyons affects the quantum state of their system in a topologically-protected way. Their expected manifestations in even-denominator fractional qua…
Quarter- and half-filled quantum Hall states and their topological orders revealed by daughter states in bilayer graphene
Ravi Kumar, André Haug, Jehyun Kim +8
Even-denominator fractional quantum Hall states are promising candidates for fault-tolerant quantum computing due to their underlying non-Abelian topological orders. However, the t…
