Carrier-mediated spin helices in low-dimensional systems: Josephson-interference features and correlation renormalization
Yung-Yeh Chang, Chen-Hsuan Hsu
Carrier-induced helical magnetism can arise in interacting one-dimensional systems coupled to localized moments. Here, we investigate the coupled-wire sliding-Luttinger-liquid coun…
Field-controlled breaking and restoration of parity-time symmetry in Josephson interference
Yi-Chen Tsai, Yung-Yeh Chang, Tao-Yi Hsu +6
Symmetry plays a fundamental role in determining the phases and physical properties of quantum matter. Controlling symmetry in mesoscopic superconducting devices provides a route t…
On the Cutting Edge: Helical Liquids in Time-Reversal-Invariant Topological Materials
Chen-Hsuan Hsu, Jelena Klinovaja, Daniel Loss
In this perspective, we discuss the unique electronic properties of helical liquids appearing at the boundaries of time-reversal-invariant topological materials and highlight the k…
Cascade of topological phase transitions and revival of topological zero modes in imperfect double helical liquids
Anna Ohorodnyk, Chen-Hsuan Hsu
Two parallel helical edge channels hosting interacting electrons, when proximitized by local and nonlocal pairings, can host time-reversal-invariant pairs of topological zero modes…
Non-Hermitian topological superconductivity with symmetry-enriched spectral and eigenstate features
Chuo-Kai Chang, Kazuma Saito, Nobuyuki Okuma +2
We investigate a one-dimensional superconducting lattice that realizes all internal symmetries permitted in non-Hermitian systems, characterized by nonreciprocal hopping, onsite di…
Engineering Majorana Kramers Pairs In Synthetic High Spin Chern Insulators
Yi-Chun Hung, Chen-Hsuan Hsu, Arun Bansil
High spin-Chern-number topological phases provide a promising low-dimensional platform for realizing double-helical edge states. In this letter, we show how these edge states can h…
Quasi-two-dimensional spin helix and magnon-induced singularity in twisted bilayer graphene
Yung-Yeh Chang, Kazuma Saito, Chen-Hsuan Hsu
Twisted bilayer graphene exhibits prominent correlated phenomena in two distinct regimes: a Kondo lattice near the magic angle, resembling heavy fermion systems, and a triangular c…
Interaction- and phonon-induced topological phase transitions in double helical liquids
Chen-Hsuan Hsu
Helical liquids, formed by time-reversal pairs of interacting electrons in topological edge channels, provide a platform for stabilizing topological superconductivity upon introduc…
Electrically tunable correlated domain wall network in twisted bilayer graphene
Hao-Chien Wang, Chen-Hsuan Hsu
We investigate the domain wall network in twisted bilayer graphene (TBG) under the influence of interlayer bias and screening effect from the layered structure. Starting from the c…
Time-Reversal Soliton Pairs In Even Spin-Chern-Number Higher-Order Topological Insulators
Yi-Chun Hung, Baokai Wang, Chen-Hsuan Hsu +2
Solitons formed through the one-dimensional mass-kink mechanism on the edges of two-dimensional systems with non-trivial topology play an important role in the emergence of higher-…
