Multiple embedded eigenstates in nonlocal plasmonic nanostructures

Author(s): Solange V. Silva, Tiago A. Morgado, and Mário G. Silveirinha

Some time ago, it was theoretically shown that materials with precisely zero permittivity offer a unique opportunity to observe light oscillations in an open system with infinite lifetime. Here, the authors investigate how the nonlocal response due to electron-electron interactions in the material affects such “embedded eigenstates.” Heuristically, one might expect that the repulsive-type electron-electron interactions should act against the light localization in an open resonator. Surprisingly, the authors prove instead that it creates the opportunity to observe eigenstates with suppressed radiation loss at multiple frequencies.

Chiral spin liquids (CSLs) are exceptional magnetic states that break time-reversal symmetry without long-range magnetic ordering. Here, the authors showcase a family of CSLs in a three-dimensional extension of the Kitaev model on the hypernonagon lattice, using quantum Monte Carlo simulations supplemented by variational calculations. Notably, all the CSLs are found to not only break time-reversal symmetry but concurrently also a number of lattice symmetries by forming a crystalline ordering of the underlying ℤ2 gauge structure. It is further shown that some of the CSLs exhibit topological features with gapless Majorana modes.

Trans-polyacetylene [$t\text{−}{(\mathrm{CH})}_{x}$] possesses twofold ground state degeneracy. Using the Su-Schrieffer-Heeger Hamiltonian, scientists predicted charged solitons to be the primary photoexcitations in $t\text{−}(\mathrm{CH}{)}_{x}$; this prediction, however, has led to sharp debate. T...

Author(s): Mauro Antezza, H. B. Chan, Brahim Guizal, Valery N. Marachevsky, Riccardo Messina, and Mingkang Wang

We study the Casimir torque between two metallic one-dimensional gratings rotated by an angle $θ$ with respect to each other. We find that, for infinitely extended gratings, the Casimir energy is anomalously discontinuous at $θ=0$, due to a critical zero-order geometric transition between a 2D- and ...
