The geometry of jamming algorithms in the random Lorentz gas
Giampaolo Folena, Patrick Charbonneau, Peter K. Morse +2
Deterministic optimization algorithms unequivocally partition a complex energy landscape in inherent structures (ISs) and their respective basins of attraction. Can these basins be…
Tunable local polariton modes in semiconductors
M. Foygel, Alexey Yamilov, Lev I. Deych +1
We study the local states within the polariton bandgap that arise due to deep defect centers with strong electron-phonon coupling. Electron transitions involving deep levels may re…
Single parameter scaling in 1-D localized absorbing systems
Lev I. Deych, Alexey Yamilov, Alexander A. Lisyansky
Numerical study of the scaling of transmission fluctuations in the 1-D localization problem in the presence of absorption is carried out. Violations of single parameter scaling for…
Local polariton modes and resonant tunneling of electromagnetic waves through periodic Bragg multiple quantum well structures
Lev I. Deych, Alexey Yamilov, Alexander A. Lisyansky
We study analytically defect polariton states in Bragg multiple-quantum-well structures and defect induced changes in transmission and reflection spectra. Defect layers can differ…
Polariton Local States in Periodic Bragg Multiple Quantum Well Structures
Lev I. Deych, A. Yamilov, A. A. Lisyansky
We analytically study optical properties of several types of defects in Bragg multiple quantum well structures. We show that a single defect leads to two local polariton modes in t…
Concept of local polaritons and optical properties of mixed polar crystals
Lev I. Deych, Alexey Yamilov, Alexander A. Lisyansky
The concept of local polaritons is used to describe optical properties of mixed crystals in the frequency region of their {\it restrahlen} band. It is shown that this concept allow…
