Correlation and transport phenomena in topological nodal-loop semimetals
Jianpeng Liu, Leon Balents
We study the unique physical properties of topological nodal-loop semimetals protected by the coexistence of time-reversal and inversion symmetries with negligible spin-orbit coupl…
Flux states and topological phases from spontaneous time-reversal symmetry breaking in CrSi(Ge)Te-based systems
Jianpeng Liu, Se Young Park, Kevin F. Garrity +1
We study adatom-covered single layers of CrSiTe and CrGeTe using first-principles calculations based on hybrid functionals. We find that the insulating ground state of a mo…
Topological nodal-line semimetals in alkaline-earth stannides, germanides and silicides
Huaqing Huang, Jianpeng Liu, David Vanderbilt +1
Based on first-principles calculations and an effective Hamiltonian analysis, we systematically investigate the electronic and topological properties of alkaline-earth compounds $A…
Tunable inverse topological heterostructure utilizing
Matthew Brahlek, Nikesh Koirala, Jianpeng Liu +6
In typical topological insulator (TI) systems the TI is bordered by a non-TI insulator, and the surrounding conventional insulators, including vacuum, are not generally treated as…
