Mapping the Berry Curvature from Semiclassical Dynamics in Optical Lattices

, 2012
We propose a general method by which experiments on ultracold gases can be used to determine the topological properties of the energy bands of optical lattices, as represented by the map of the Berry curvature across the Brillouin zone.

Phonon Driven Ferroelectricity and Raman Active Modes in Hybrid Organic‐Inorganic Perovskites

Advanced Materials, EarlyView.
Ferroelectric domains, a hallmark of ferroelectricity, are studied using temperature‐dependent Raman spectroscopy to uncover characteristic phonons associated with ferroelectric phase transitions in different n‐value HOIPs. Higher n‐value HOIP demonstrate a reduced ferroelectric switching energy barrier, providing valuable insights for optimizing ...

Potassium in the Grape (Vitis vinifera L.) Berry: Transport and Function

Frontiers in Plant Science, 2017
K+ is the most abundant cation in the grape berry. Here we focus on the most recent information in the long distance transport and partitioning of K+ within the grapevine and postulate on the potential role of K+ in berry sugar accumulation, berry water ...

Charged exctions in two-dimensional transition-metal dichalcogenides - semiclassical calculation of Berry-curvature effects

, 2018
We theoretically study the role of the Berry curvature on neutral and charged excitons in two-dimensional transition-metal dichalcogenides. The Berry curvature arises due to a strong coupling between the conduction and valence bands in these materials ...

Proposing Altermagnetic‐Ferroelectric Type‐III Multiferroics with Robust Magnetoelectric Coupling

Advanced Materials, EarlyView.
Multiferroics are highly sought after for advanced technological applications. Here, a novel class of type‐III multiferroics is proposed, where ferroelectricity and altermagnetism are inherently interlocked by crystal symmetry, setting them apart from conventional multiferroics. The ferroelectric switching is shown to fully invert the spin polarization

Evaluation of protective devices for the direct seeding of longleaf pine (Pinus palustris)

Trees, Forests and People
Most tree species, including longleaf pine (Pinus palustris Mill.; LLP) are established by planting seedlings during reforestation. Direct seeding could be a viable alternative; however, seed predation by various animals might be an impediment. While LLP

Tailoring Robust Quantum Anomalous Hall Effect via Entropy‐Engineering

Advanced Materials, EarlyView.
Bandstructure renormalization, without (w/o) spin‐orbit interaction (SOI) (left) and with SOI (right), in the low‐energy Dirac bands of zero‐entropy (purple) and entropic (green) VCl3 monolayer (ML) with long‐range ordering (LRO). Abstract The development of quantum materials and the tailoring of their functional properties is of fundamental interest ...

Exploring DNA Functionalization Techniques for Silver Nanoparticles

Advanced Materials Interfaces, EarlyView.
This study evaluates four functionalization methods—salt‐aging, pH‐assisted, freezing‐directed, and microwave‐assisted—for attaching DNA strands to 20 nm silver nanoparticles (AgNPs). The resulting DNA‐AgNP conjugates are characterized and colloidal stability and DNA loading are assessed.
