WebbAbstract: Optical non-reciprocity, a phenomenon that allows unidirectional flow of optical field is pivoted on the time reversal symmetry breaking. The symmetry breaking happens in the cavity optomechanical system (COS) due to non uniform radiation pressure as a result of light-matter interaction, and is crucial in building non-reciprocal optical devices. Webb24 mars 2024 · Emergence of spin–charge conversion functionalities due to spatial and time-reversal asymmetries and chiral symmetry Authors Kondou, Kouta 1, 2; Otani, Yoshichika 1, 2, 3; 1 Center for Emergent Matter Science (CEMS), Saitama, (Japan) ; 2 Japan Science and Technology Agency (JST), Kawaguchi, Saitama, (Japan) ; 3 The …
Mechanical nonreciprocity in a uniform composite material
Webb16 juni 2000 · We show that reciprocity, energy (or probability) conservation, and time-reversal symmetry in the presence of evanescent waves lead to relationships that extend the well-known relations previously derived in asymptotic scattering. On this basis, we discuss the link between reciprocity and time-reversal symmetry. Webb21 sep. 2024 · This work presents a controllable space–time acoustic phased array which breaks time-reversal symmetry, and enables … rainbow friends blue monster
Odd Willis coupling induced by broken time-reversal symmetry
Webb10 maj 2024 · In these systems, Willis coupling obeys reciprocity, imposing an even symmetry of the Willis coefficients with respect to time reversal and the impinging wave vector, which translates into ... Webb10 apr. 2024 · This paper shows that Onsager reciprocal relations remain valid even in presence of a generic magnetic field so that the time reversal symmetry is broken. The … Webb8 apr. 2024 · A threefold-symmetric pattern is seen in the top part of the image, while the reconstruction on the lower part exhibits a preferential symmetry axis. This pattern was ascribed to an incommensurate CDW, resulting from the competition between the hexagonal (3 × 3) and the rectangular ( 3 3 / 2 × 4 ) $(3\sqrt 3 /2 \times 4)$ R 30° sharing … rainbow friends blue to color
