Fluctuational Quantum Electrodynamics of Dispersive Time-Varying Media
Jaime E. Sustaeta-Osuna, Thomas F. Allard, Francisco J. GarcÃa-Vidal +1
We present the theoretical framework of fluctuational quantum electrodynamics in frequency-dispersive and dissipative time-varying media. Our theory accounts for dispersion and los…
Broadband Dipole Absorption in Dispersive Photonic Time Crystals
Thomas F. Allard, Jaime E. Sustaeta-Osuna, Francisco J. GarcÃa-Vidal +1
Photonic media modulated periodically in time, termed photonic time crystals (PTCs), have attracted considerable attention for their ability to open momentum bandgaps hosting ampli…
Interface States in Space-Time Photonic Crystals: Topological Origin, Propagation and Amplification
Alejandro Caballero, Thomas F. Allard, Paloma A. Huidobro
Studying the topology of spatiotemporal media poses a fundamental challenge: their remarkable properties stem from breaking spatial and temporal symmetries, yet this same breaking…
Constructing qubit edge states by inverse-designing the electromagnetic environment
A. Miguel-Torcal, T. F. Allard, P. A. Huidobro +2
Building on advances in topological photonics and computational optimization, we inversedesign a periodic dielectric structure surrounding a chain of interacting qubits, emulating…
Near-Field Gain and Far-Field Control via a Plasmonic Time Crystal Slab
Jaime E. Sustaeta-Osuna, Thomas F. Allard, Francisco J. GarcÃa-Vidal +1
Light matter interactions can be substantially altered in the presence of time varying media. We study the interaction between a harmonic electric dipole and a plasmonic time cryst…
Plasmonic Brownian Ratchets for Directed Transport of Analytes
Marciano Palma do Carmo, David Mack, Diane J. Roth +6
Controlled long-range transport of micro- and nano-scale objects is a key requirement in lab-on-a-chip and microfluidic applications, enabling the efficient capture, concentration,…
