Spin Configurations of Anyonic excitations in Moiré Fractional Chern Insulators
Vadym Apalkov, Tapash Chakraborty
We have examined the nature of elementary excitations in particular, their spin polarization, in recently discovered zero-field fractional Chern insulator in twisted bilayer MoTe$_…
Discernible signatures of fractionally charged anyons in a Pfaffian-Laughlin state
Vadym Apalkov, Tapash Chakraborty
Understanding the nature of quasihole excitations, i.e., anyons that have fractional charge and fractional statistics, has been a challenging problem in condensed matter physics. O…
Correlated Quantum Phenomena in Confined Two-Dimensional Hexagonal Crystals
Xiang Liua, Zheng Taoa, Wenchen Luoa +1
Low-energy fermionic excitations in two-dimensional materials deviate from the conventional Schrödinger description and are instead governed by Dirac equations. Such Dirac fermions…
Selective enhancement of Coulomb interactions in planar Weyl fermions
Vadym Apalkov, Wenchen Luo, Tapash Chakraborty
We report on our study of the electron interaction effects in topological two-dimensional (2D) materials placed in a quantizing magnetic field. Taking our cue from a recent experim…
Interlayer excitons in double-layer transition metal dichalcogenides quantum dots
Xiang Liu, Zheng Tao, Wenchen Luo +1
Various properties of interlayer excitons in double-layer transition metal dichalcogenides quantum dots are analyzed using a low-energy effective Hamiltonian with Coulomb interacti…
