Rashba Spin-Orbit Driven Topological Phase Transitions in Heterogeneous Armchair Honeycomb Nanoribbons
Hao-Ru Wu, Jhih-Shih You, Yiing-Rei Chen +1
We investigate the emergence of nontrivial topological phases in heterogeneous armchair honeycomb nanoribbons arising from the interplay between structural geometry and Rashba spin…
Impurity-Induced Interference at a Topological Boundary in an Infinite SSH Heterojunction
Hao-Ru Wu, Hong-Yi Chen, Yiing-Rei Chen
In this work, we investigate the coupling between a strong impurity and the topological boundary of an SSH heterojunction, composed of two SSH chains belonging to different topolog…
Complex magnetic phases and thermodynamics of CuB_2O_4
C. H. Lai, M. -J. Hsieh, N. Puri +9
The copper metaborate CuB_2O_4(CBO) has been studied within the parametric space of magnetic field (B) and temperature (T), showing a series of distinct phases, including commensur…
Theory of valley-dependent transport in graphene-based lateral quantum structures
Feng-Wu Chen, Mei-Yin Chou, Yiing-Rei Chen +1
Modulation of electronic states in two-dimensional (2D) materials can be achieved by using in-plane variations of the band gap or the average potential in lateral quantum structure…
Gibbs paradox and a possible mechanism of like-charge attraction in colloids
Chi-Lun Lee, Yiing-Rei Chen
Based on a reconsideration of the Gibbs paradox, we show that a residual, non-extensive term in entropy turns up upon mixing identical particles, whether they are indistinguishable…
Octahedral Tilt Instability of ReO_3-type Crystals
Philip B. Allen, Yiing-Rei Chen, Santanu Chaudhuri +1
The octahedron tilt transitions of ABX_3 perovskite-structure materials lead to an anti-polar (or antiferroelectric) arrangement of dipoles, with the low temperature structure havi…
Density Functional Study of Cubic to Rhombohedral Transition in -AlF
Yiing-Rei Chen, Vasili Perebeinos, Philip B. Allen
Under heating, -AlF undergoes a structural phase transition from rhombohedral to cubic at temperature around 730 K. The density functional method is used to examine the…
Polaronic Signatures in Mid-Infrared Spectra: Prediction for LaMnO3 and CaMnO3
Yiing-Rei Chen, Vasili Perebeinos, Philip B. Allen
Hole-doped LaMnO3 and electron-doped CaMnO3 form self-trapped electronic states. The spectra of these states have been calculated using a two orbital (Mn eg Jahn-Teller) model, fro…
Spin versus Lattice Polaron: Prediction for Electron-Doped CaMnO3
Yiing-Rei Chen, Philip B. Allen
CaMnO3 is a simple bi-partite antiferromagnet(AF) which can be continuously electron-doped up to LaMnO3. Electrons enter the doubly degenerate E_g subshell with spins aligned to th…
