Inherited topological superconductivity in two-dimensional Dirac semimetals
Chiu Fan Bowen Lo, Hoi Chun Po, Andriy H. Nevidomskyy
Under what conditions does a superconductor inherit topologically protected nodes from its parent normal state? In the context of Weyl semimetals with broken time-reversal symmetry…
Symmetric Jordan-Wigner transformation in higher dimensions
Hoi Chun Po
The Jordan-Wigner transformation is traditionally applied to one dimensional systems, but recent works have generalized the transformation to fermionic lattice systems in higher di…
Higher-dimensional Jordan-Wigner Transformation and Auxiliary Majorana Fermions
Kangle Li, Hoi Chun Po
We discuss a scheme for performing Jordan-Wigner transformation for various lattice fermion systems in two and three dimensions which keeps internal and spatial symmetries manifest…
Unconventional hysteretic transition in a charge density wave
B. Q. Lv, Alfred Zong, D. Wu +25
Hysteresis underlies a large number of phase transitions in solids, giving rise to exotic metastable states that are otherwise inaccessible. Here, we report an unconventional hyste…
Exciton-driven antiferromagnetic metal in a correlated van der Waals insulator
Carina A. Belvin, Edoardo Baldini, Ilkem Ozge Ozel +11
Collective excitations of bound electron-hole pairs -- known as excitons -- are ubiquitous in condensed matter, emerging in systems as diverse as band semiconductors, molecular cry…
Location and topology of the fundamental gap in photonic crystals
Thomas Christensen, Hoi Chun Po, John D. Joannopoulos +1
The fundamental, or first, band gap is of unmatched importance in the study of photonic crystals. Here, we address precisely where this gap can be opened in the band structure of t…
