Network Topology Governs Photocatalytic Water Splitting in Organic Two‐Dimensional Crystals

Advanced Functional Materials, EarlyView.
Network topology in organic two‐dimensional crystals (O2DCs) dictates the photocatalytic water splitting performance. Kagome‐lattice O2DCs exhibit strong electron‐hole mass asymmetry, spatially separated carriers, and longer recombination lifetimes, exceeding rhombic isomers.

Exciton-polariton condensates near the Dirac point in a triangular lattice [PDF]

, 2013
Dirac particles, massless relativistic entities, obey linear energy dispersions and hold important implications in particle physics. The recent discovery of Dirac fermions in condensed matter systems including graphene and topological insulators has ...

Evidence for Itinerant Ferromagnetic Flat Bands Producing Large Transverse Responses

Advanced Materials, EarlyView.
Itinerant ferromagnetic flat bands are demonstrated in GdCo5 with a high Curie temperature of 940K, a stacked honeycomb–kagome lattice, through angle‐resolved photoemission spectroscopy and magneto‐thermoelectric measurements. These topological flat bands generate large Berry curvaturte, producing gigantic anomalous Nernst effect with record‐high ...

Paraxial Dirac equation [PDF]

, 2023
In this work, the paraxial approximation of the free Dirac equation is examined. The results are first obtained by constructing superpositions of exact solutions with suitable profiles, which are borrowed from paraxial optics.

OCTONIONIC VERSION OF DIRAC EQUATIONS [PDF]

International Journal of Modern Physics A, 2006
It is shown that a simple continuity condition in the algebra of split octonions suffices to formulate a system of differential equations that are equivalent to the standard Dirac equations. In our approach the particle mass and electromagnetic potentials are part of an octonionic gradient function together with the space–time derivatives. As distinct

Correlated Charge Transport in an Organic Coulomb Glass

Advanced Materials, EarlyView.
ABSTRACT Advances in the development of organic field‐effect transistors (OFETs), electrically gated organic semiconductors (EGOFETs), and organic electrochemical transistors (OECTs) allow for the operation of these devices at very high charge‐carrier densities, where Coulomb interactions between carriers can be expected to become significant.

Levinson’s theorem for the Dirac equation [PDF]

Physical Review Letters, 1993
Summary: Levinson's theorem for the Dirac equation is known in the form of a sum of positive and negative energy phase shifts at zero momentum related to the total number of bound states. In this letter we prove a stronger version of Levinson's theorem valid for positive and negative energy phase shifts separately.
