Beyond Lambertian light trapping for large-area silicon solar cells: fabrication methods
Jovan Maksimovic, Jingwen Hu, Soon Hock Ng +7
Light trapping photonic crystal (PhC) patterns on the surface of Si solar cells provides a novel opportunity to approach the theoretical efficiency limit of 32.3%, for light-to-ele…
Three-dimensional femtosecond laser nanolithography of crystals
Airan Rodenas, Min Gu, Giacomo Corrielli +4
Nanostructuring hard optical crystals has so far been exclusively feasible at their surface, as stress induced crack formation and propagation has rendered high precision volume pr…
Topological light-trapping on a dislocation
Fei-Fei Li, Hai-Xiao Wang, Zhan Xiong +6
Topology has been revealed to play a fundamental role in physics in the past decades. Topological insulators have unconventional gapless edge states where disorder-induced back-sca…
Topological transitions in continuously-deformed photonic crystals
Xuan Zhu, Hai-Xiao Wang, Changqing Xu +3
We demonstrate that multiple topological transitions can occur, with high-sensitivity, by continuous change of the geometry of a simple 2D dielectric-frame photonic crystal consist…
Photonic Architectures for Equilibrium High-Temperature Bose-Einstein Condensation in Dichalcogenide Monolayers
Jian-Hua Jiang, Sajeev John
Semiconductor-microcavity polaritons are composite quasiparticles of excitons and photons, emerging in the strong coupling regime. As quantum superpositions of matter and light, po…
Photonic Crystal Architecture for Room Temperature Equilibrium Bose-Einstein Condensation of Exciton-Polaritons
Jian-Hua Jiang, Sajeev John
We describe photonic crystal microcavities with very strong light-matter interaction to realize room-temperature, equilibrium, exciton-polariton Bose-Einstein condensation (BEC). T…
A Microscopic Model for D-Wave Pairing in the Cuprates: What Happens when Electrons Somersault?
Mona Berciu, Sajeev John
We present a microscopic model for a strongly repulsive electron gas on a 2D square lattice. We suggest that nearest neighbor Coulomb repulsion stabilizes a state in which electron…
Radiating dipoles in photonic crystals
Kurt Busch, Nipun Vats, Sajeev John +1
The radiation dynamics of a dipole antenna embedded in a Photonic Crystal are modeled by an initially excited harmonic oscillator coupled to a non--Markovian bath of harmonic oscil…
A microscopic model for d-wave charge carrier pairing and non-Fermi-liquid behavior in a purely repulsive 2D electron system
Mona Berciu, Sajeev John
We investigate a microscopic model for strongly correlated electrons with both on-site and nearest neighbor Coulomb repulsion on a 2D square lattice. This exhibits a state in which…
Quantum dynamics of charged and neutral magnetic solitons: Spin-charge separation in the one-dimensional Hubbard model
Mona Berciu, Sajeev John
We demonstrate that the Configuration Interaction (CI) Approximation recaptures essential features of the exact (Bethe Ansatz) solution to the 1D Hubbard model. As such, it provide…
Non-Markovian Quantum Fluctuations and Superradiance Near a Photonic Band Edge
Nipun Vats, Sajeev John
We discuss a point model for the collective emission of light from N two-level atoms in a photonic bandgap material, each with an atomic resonant frequency near the edge of the gap…
A numerical study of multi-soliton configurations in a doped antiferromagnetic Mott insulator
Mona Berciu, Sajeev John
We evaluate from first principles the self-consistent Hartree-Fock energies for multi-soliton configurations in a doped, spin-1/2, antiferromagnetic Mott insulator on a two-dimensi…
Quantum self-induced transparency in frequency gap media
Sajeev John, Valery I. Rupasov
We study quantum effects of light propagation through an extended absorbing system of two-level atoms placed within a frequency gap medium (FGM). Apart from ordinary solitons and s…
Multiphoton localization and propagating quantum gap solitons in a frequency gap medium
Sajeev John, Valery I. Rupasov
The many-particle spectrum of an isotropic frequency gap medium doped with impurity resonance atoms is studied using the Bethe ansatz technique. The spectrum is shown to contain pa…
