Phase diagram of a frustrated asymmetric ferromagnetic spin ladder

, 2016
We perform a systematic investigation on the ground state of an asymmetric two-leg spin ladder (where exchange couplings of the legs are unequal) with ferromagnetic (FM) nearest-neighbor interaction and diagonal anti-ferromagnetic frustration using the ...

Dual polarization operation of nanostructure arrays in the MIR region [PDF]

, 2018
In this paper, we report on arrays of asymmetric split H-shape nanostructures tuned to produce two distinct resonances at wavelengths that range from 3 μm to 7 μm.

On asymmetric structures

Discrete Mathematics, 1992
AbstractA given structure is said to be asymmetric if its automorphism group reduces to the identity. The problem of enumerating asymmetric structures (and, more generally, to count structures according to stabilizers) is usually solved by making use of Möbius inversion techniques and symmetric functions in the context of group actions.

Enantioselective acyl-trifluoromethylation of olefins by bulky thiazolium carbene catalysis

Nature Communications
Enantioenriched α-chiral β-fluorinated ketones are valuable structural motifs with application in several fields. The recently emerged concept of NHC-catalyzed radical acyl-trifluoromethylation of olefins offers a rapid route to construct racemic β ...

Parallel Coupling of Symmetric and Asymmetric Exclusion Processes

, 2008
A system consisting of two parallel coupled channels where particles in one of them follow the rules of totally asymmetric exclusion processes (TASEP) and in another one move as in symmetric simple exclusion processes (SSEP) is investigated theoretically.

Volume inequalities for asymmetric Orlicz zonotopes [PDF]

arXiv, 2015
In this paper, we deal with the asymmetric Orlicz zonotopes by using the method of shadow system. We establish the volume product inequality and volume ratio inequality for asymmetric Orlicz zonotopes, along with their equality cases.

Rectification in Luttinger liquids

, 2004
We investigate the rectification of an ac bias in Luttinger liquids in the presence of an asymmetric potential (the ratchet effect). We show that strong repulsive electron interaction enhances the ratchet current in comparison with Fermi liquid systems ...

Renewal theory for asymmetric $U$-statistics [PDF]

arXiv, 2018
We extend a functional limit theorem for symmetric $U$-statistics [Miller and Sen, 1972] to asymmetric $U$-statistics, and use this to show some renewal theory results for asymmetric $U$-statistics. Some applications are given.

On Symmetric and Asymmetric LSHs for Inner Product Search [PDF]

, 2015
We consider the problem of designing locality sensitive hashes (LSH) for inner product similarity, and of the power of asymmetric hashes in this context.
