Directional Flow of Confined Polaritons in CrSBr

open access: yesAdvanced Materials, EarlyView.
CrSBr, a layered magnetic semiconductor, naturally channels self‐hybridized excitonpolaritons into highly directional flow. Its intrinsic optical anisotropy, high refractive index, and strong lightmatter coupling enable long‐range guided modes along the a‐axis, with propagation lengths set by their excitonphoton admixture.

Currency Substitution in the Transition Economy : A Case of the Czech Republic 1993-2001 [PDF]

open access: yes
Currency substitution appears to be an important issue affecting the design of monetary policy, especially in transition economies. Therefore, this paper strives to analyze the particular relevance of a currency substitution phenomenon for the Czech ...

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD

open access: yesAdvanced Materials, EarlyView.
Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Effects of the construction of a reservoir on the fish assemblage in an inflow river

open access: yesCzech Journal of Animal Science, 2008
The construction of the Římov Reservoir on the Malše River in 1978 significantly influenced the fish assemblage within the river, above the reservoir. Fish species that had successfully colonised the reservoir after impoundment expanded to the inflowing ...

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

open access: yesAdvanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Microwave Absorption for Detection of Dirac Fermions in SnTe Films

open access: yesAdvanced Materials Interfaces, EarlyView.
Microwave absorption can detect Dirac fermions in samples exposed to the atmosphere. Results showed that although topological surface states are robust against environmental degradation, they are not detectable by electrical transport measurements. Hence, microwave absorption can detect Dirac fermions even in samples whose surfaces have deteriorated ...

Are Eastern European Countries Catching Up? Time Series Evidence for Czech Republic, Hungary, and Poland [PDF]

open access: yes
The catching up process in Czech Republic, Hungary, and Poland is analyzed by investigating the integration properties of log-differences in per-capita GDP versus the EU15 and a Mediterranean country group. We account for structural changes by using unit
