Protected Chaos in a Topological Lattice

Advanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

Blue‐to‐Green Fine‐Tunable Narrowband Delayed Fluorescence in Peripherally Dendritic Modified Bis‐Indolocarbazoles

Angewandte Chemie, EarlyView.
An exquisite color tuning of narrowband thermally activated delayed fluorescence from deep‐blue to green was achieved for non‐boron ubiquitous luminophores based on the dendritic modification design concept. The corresponding OLEDs exhibited high‐efficiency, high‐color‐purity blue and green electroluminescence, with high external quantum efficiencies ...

Remark on wave front sets of solutions to Schrödinger equation of a free particle and a harmonic oscillator

SUT Journal of Mathematics, 2011
In this paper, we determine the wave front sets of solutions to the Schrödinger equations of the Schrödinger evolution operator of a free particle and of a harmonic oscillator by using the representation of the Schrödinger evolution operator of a free ...

Probing Anisotropic Quasiparticle Dynamics and Topological Phase Transitions in Quasi‐1D Topological Insulator ZrTe5

Advanced Science, EarlyView.
This study reveals quasiparticle dynamics in ZrTe5. Polarization‐dependent measurements show transient reflectivity anisotropy arises from electron relaxation and lattice vibrations. The first dynamical evidence of a temperature‐induced Lifshitz transition is reported.

Azuperylene: The Nonalternant Isomer of Perylene

Angewandte Chemie, EarlyView.
As a nonalternating isomer of perylene, azuperylene (AP) is formed by the C─H/C─I coupling reactions we developed at the 1,8‐positions of azulene. The aromatic characteristics of the initial azulene are retained, and side chain modifications regulate the stacking pattern. The core of AP has smaller mutual perturbation compared to perylene.

Determination of Approximate Periods of Duffing-harmonic Oscillator

Walailak Journal of Science and Technology, 2014
We introduced an analytical technique based on harmonic balance method (HBM) to determine approximate periods of a nonlinear Duffing-harmonic oscillator. Generally, a set of nonlinear algebraic equations are appeared when HBM is formulated.

Cooper pairing and single particle properties of trapped Fermi gases

, 2002
We calculate the elementary excitations and pairing of a trapped atomic Fermi gas in the superfluid phase. The level spectra and pairing gaps undergo several transitions as the strength of the interactions between and the number of atoms are varied.
