Chiral adiabatic transmission protected by Fermi surface topology

SciPost Physics
We demonstrate that Andreev modes that propagate along a transparent Josephson junction have a perfect transmission at the point where three junctions meet.

The Topological Vertex

, 2003
We construct a cubic field theory which provides all genus amplitudes of the topological A-model for all non-compact Calabi-Yau toric threefolds.

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Fiber Bundle Topology Optimization for Surface Flows

Chinese Journal of Mechanical Engineering
This paper presents a topology optimization approach for the surface flows on variable design domains. Via this approach, the matching between the pattern of a surface flow and the 2-manifold used to define the pattern can be optimized, where the 2 ...

Investigation on Surface Roughness of Inconel 718 in Photochemical Machining

Advances in Materials Science and Engineering, 2017
The present work is focused on estimating the optimal machining parameters required for photochemical machining (PCM) of an Inconel 718 and effects of these parameters on surface topology.

Functional integration on two dimensional Regge geometries

, 1996
By adopting the standard definition of diffeomorphisms for a Regge surface we give an exact expression of the Liouville action both for the sphere and the torus topology in the discretized case.

Surface topology assisted alignment of Min protein waves

FEBS Letters, 2014
Self‐organization of proteins into large‐scale structures is of pivotal importance for the organization of cells. The Min protein system of the bacterium Escherichia coli is a prime example of how pattern formation occurs via reaction–diffusion.

Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

Advanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

Weighted and metric surface networks - new insights and an interactive application for their generalisation in Tcl/Tk [PDF]

, 2000
The idea of characterising the different forms of natural topographic surfaces by a topologicalmodel based on their fundamental surface features has attracted many proposals. In this paper, adetailed discussion and new proposals on various issues related
