Moiré semiconductors on twisted bilayer dice lattice
Di Ma, Yu-Ge Chen, Yue Yu +1
We propose an effective lattice model for the moiré structure of the twisted bilayer dice lattice. In the chiral limit, we find that there are flat bands at the zero-energy level…
Intrinsic chiral topological superconductor thin films
Xi Luo, Yu-Ge Chen, Ziqiang Wang +1
Superconductors (SCs) with nontrivial topological band structures in the normal state have been discovered recently in bulk materials. When such SCs are made into thin films, quant…
Quantum chaos associated with emergent ergosurface in transition layer between type-I and type-II Weyl semimetals
Yu-Ge Chen, Xi Luo, Fei-Ye Li +2
We present emergent ergosurfaces (ES) in a transition layer between type-I and type-II Weyl semimetals (WSMs). The Hawking temperature defined by the surface gravity at the acousti…
Magneto-optical Conductance of Kane Fermion Gas in Low Frequencies
Xi Luo, Yu-Ge Chen, Yue Yu
Kane fermion is the counterpart of the Dirac fermion with pseudospin-1. Due to the existence of a bunch of gapless modes associated with Landau levels, the magnetic transport prope…
Universal topological quantum computation with strongly correlated Majorana edge modes
Ye-Min Zhan, Yu-Ge Chen, Bin Chen +3
Majorana-based quantum gates are not complete for performing universal topological quantum computation while Fibonacci-based gates are difficult to be realized electronically and h…
Towards Bulk Locality: A Systematic Construction of Contact Interactions from Chord Diagrams
Hao Dai, Yi-Li Wang, Yu-Ge Chen +2
Chord diagrams encode boundary correlators in the double-scaled holographic Sachdev-Ye-Kitaev model, but currently capture only a limited class of bulk interactions that yield pure…
Dissipationless topological quantum computation for Majorana objects in sparse-dense mixed encoding process
Ye-Min Zhan, Guan-Dong Mao, Yu-Ge Chen +2
Topological quantum computation based on Majorana objects is subject to a significant challenge because at least some of the two-qubit quantum gates rely on the fermion (either cha…
Correlated helimagnetic configuration in a nonsymmorphic magnetic nodal semimetal
Xi Luo, Yu-Ge Chen, Ye-Min Zhan +1
Nonsymmorphic magnetic Weyl semimetal materials such as ReAlX (Re=rare earth, X=Si/Ge) provide a unique opportunity to explore the correlated phenomena between Weyl fermions and no…
Topological superconductor from superconducting topological surface states and fault-tolerant quantum computing
Xi Luo, Yu-Ge Chen, Ziqiang Wang +1
The chiral -wave superconductor/superfluid in two dimensions (2D) is the simplest and most robust system for topological quantum computation . Candidates for such topological su…
