Robustness of Floquet topological phase at room temperature: a first-principles dynamics study
Nonadiabatic Thouless pumping of electrons is studied within the framework of topological Floquet engineering, particularly focused on how atomic lattice dynamics affect the emergent Floquet topological phase in trans-polyacetylene under the driving electric field. As similarly done in the earlier work [Zhou and Kanai, J. Phys. Chem. Lett., 12, 4496 (2021)], the real-time time-dependent density functional theory and Ehrenfest dynamics simulations were used to investigate the extent to which the…

Molecular Control of Floquet Topological Phase in Non-adiabatic Thouless Pumping
Nonadiabatic Thouless pumping of electrons is studied in the framework of topological Floquet engineering, particularly focused on how changes to chemical moieties can control the emergence of the Floquet topological phase. We employ real-time time-dependent density functional theory to investigate the extent to which the topological invariant, the winding number, is impacted by molecular-level changes to trans-polyacetylene. In particular, several substitutions to trans-polyacetylene are studi…

Approach to network failure due to intrinsic fluctuations
A networked system can fail when most of its components are unable to support flux through the nodes and edges. As studied earlier this scenario can be triggered by an external perturbation such as an intentional attack on nodes or for internal reasons such as due to malfunction of nodes. In either case, the asymptotic failure of the network is preceded by a cascade of nodal failures. In this work, we focus on the nodal failure arising from the intrinsic fluctuations in the flux passing through…

The Trump administration is thinking about adding 26 more countries
—most of them African
—to his travel ban list.
The Washington Post obtained a Trump administration memo that would give the 26 countries listed 60 days to capitulate to State Department demands.
Some countries were flagged for having “no competent or cooperative central government authority to produce reliable identity documents or other civil documents,”
or “government fraud.”
There was …

Evolution of energy density fluctuations in the presence of a magnetic field
In this proceeding, we study the evolution of energy density fluctuations in the presence of a static and uniform magnetic field. By numerically solving the relativistic Boltzmann-Vlasov equation within the relaxation time approximation and performing the momentum mode analysis of different wavelength fluctuations, we show that the magnetic field increases the damping of mode oscillations. This causes a qualitative change in the fluctuations present in the system at the timescale required to ac…
