Non-Hermitian topological devices with Chern insulators
Kyrylo Ochkan, Michael Wissmann, Louis Veyrat +9
Multi-terminal topological devices are a new generation of electronic devices with quantized properties robust against imperfections. In magnetic topological insulators, dissipatio…
Generating ferro-spinetic polarizations in altermagnetic insulators
Toshihiro Sato, Mengli Hu, Ion Cosma Fulga +5
Altermagnets are a novel class of fully spin-compensated magnetic materials that nevertheless have spin-split electronic bands, offering novel perspectives for spintronics applicat…
Noise resilience of two-dimensional Floquet topological phases
Balaganchi A. Bhargava, Sanjib Kumar Das, Lukas M. Sieberer +1
We study the effect of noise on two-dimensional periodically driven topological phases, focusing on two examples: the anomalous Floquet-Anderson phase and the disordered Floquet-Ch…
Topological nodal -wave superconductivity in PtBi
Susmita Changdar, Oleksandr Suvorov, Andrii Kuibarov +11
Most superconducting materials are well-understood and conventional in the sense that the pairs of electrons that cause the superconductivity by their condensation have the highest…
Exploring Topological Effects in Thin-Film X-Ray Cavities
Hanns Zimmermann, Jonathan Sturm, Ion Cosma Fulga +2
Quantum control of single x-ray photons can be achieved using thin-film nanostructure cavities with embedded layers of resonant nuclei. Here, we design and theoretically investigat…
Topological properties of domain walls in antiferromagnetic topological insulators
Gabriele Naselli, Ion Cosma Fulga
Motivated by the study of stacking faults in weak topological insulators and the observation of magnetic domain walls in MnBiTe, we explore the topological properti…
Electronic structure and hinge states of strained half-Heusler compounds LiSbZn and LiBiZn
Sanjib Kumar Das, Ion Cosma Fulga, Rakshanda Dhawan +3
Half-Heusler compounds are a class of materials with great potential for the study of distinct electronic states. In this work, we investigate, from first-principles, the possibili…
Tuning the topological winding number by rolling up graphene
Ying-Je Lee, Yu-An Cheng, Yu-Jie Zhong +2
Nanoscrolls, radial superlattices formed by rolling up a nanomembrane, exhibit distinct electronic and magneto-transport properties compared to their flat counterparts. In this stu…
