Protected chaos in a topological lattice
Haydar Sahin, Hakan Akgün, Zhuo Bin Siu +4
The erratic nature of chaotic behavior is thought to erode the stability of periodic behavior, including topological oscillations. However, we discover that in the presence of chao…
Anomalous Non-Hermitian Skin Effects in Coupled Hermitian Chains with Cross-Coupling
S M Rafi-Ul-Islam, Zhuo Bin Siu, Md. Saddam Hossain Razo +1
In this work, we demonstrate the presence of an anomalous non-Hermitian skin effects which decay from both ends of a system consisting of two coupled Hermitian chains induced by no…
Dynamic Manipulation of Non-Hermitian Skin Effect through Frequency in Topolectrical Circuits
S M Rafi-Ul-Islam, Zhuo Bin Siu, Md. Saddam Hossain Razo +1
One of the most fascinating phenomena in non-Hermitian systems is the extensive accumulation of the bulk eigenstates under open-boundary conditions which is known as the non-Hermit…
Saturation Dynamics in Non-Hermitian Topological Sensing Systems
S. M. Rafi-Ul-Islam, Zhuo Bin Siu, Md. Saddam Hossain Razo +1
A class of non-Hermitian topological sensors (NTOSs) was recently proposed in which the NTOS comprises a non-Hermitian Su-Schrieffer-Heeger chain with a measurant-dependent couplin…
Spin Orbit Torque on a Curved Surface
Seng Ghee Tan, Che Chun Huang, Mansoor B. A. Jalil +1
We provide a general formulation of the spin-orbit coupling on a 2D curved surface. Considering the wide applicability of spin-orbit effect in spinor-based condensed matter physics…
