Nonreciprocal Single-Photon Band Structure

Physical Review Letters, 2022
We study single-photon band structure in a one-dimensional (1D) coupled-resonator optical waveguide (CROW) which chirally couples to an array of two-level quantum emitters (QEs). The chiral interaction between the resonator mode and the QE can break the time-reversal symmetry without the magneto-optical effect.

Complex-Eigenfrequency Band Structure of Viscoelastic Phononic Crystals

Applied Sciences, 2019
The consideration of material losses in phononic crystals leads naturally to the introduction of complex valued eigenwavevectors or eigenfrequencies representing the attenuation of elastic waves in space or in time, respectively.

Band structure from random interactions [PDF]

, 1999
The anharmonic vibrator and rotor regions in nuclei are investigated in the framework of the interacting boson model using an ensemble of random one- and two-body interactions. We find a predominance of L(P)=0(+) ground states, as well as strong evidence

Theoretical investigation of structural, electronic, dielectric and optical characteristics of cubic perovskite BaCeO3 [PDF]

Processing and Application of Ceramics, 2021
Structural, electronic and optical parameters of a cubic perovskite BaCeO3 were calculated using FP-LAPW with WIEN2K code. The calculated band structure confirmed the semiconducting behaviour of BaCeO3 with an indirect band gap of 2.33 eV.
