Floquet-Engineered Odd-Parity Altermagnetic Higher-Order Topology in a Two-Dimensional Antiferromagnet CrCH
Xiaorong Zou, Hyeon Suk Shin, Baibiao Huang +5
Periodic driving provides a platform to dynamically tailor quantum states of matter, yet its impact on symmetry-protected topological phases remains incompletely understood. Here,…
Second-order topology in two-dimensional azulenoid kekulene carbon lattices
Xiaorong Zou, Hyeon Suk Shin, Chang-Jong Kang +5
The discovery of higher-order topological insulator (HOTI) has established a new paradigm for understanding symmetry-constrained boundary electronic states. Here, based on first-pr…
Indium selenides for next-generation low-power computing devices
Seunguk Song, Michael Altvater, Wonchan Lee +3
As silicon-based computing approaches fundamental physical limits in energy efficiency, speed, and density, the search for complementary materials to extend or replace CMOS technol…
Reconfigurable, non-volatile control of optical anisotropy in ReS2 via ferroelectric gating
Mahfujur Rahaman, Seunguk Song, Aaliyah C. Khan +8
Electrically tunable linear dichroism (LD) with non-volatile properties represents a critical yet elusive feature for next-generation integrated photonic elements in practical devi…
