Hierarchical Mean-Field Operator Bounds on Electromagnetic Scattering: Upper Bounds on Near-Field Radiative Purcell Enhancement
Sean Molesky, Pengning Chao, Alejandro W. Rodriguez
We show how the central equality of scattering theory, the definition of the operator, can be used to generate hierarchies of mean-field constraints that act as natura…
Near-field Radiative Heat Transfer in Many-Body Systems
Svend-Age Biehs, Riccardo Messina, Prashanth S. Venkataram +3
Many-body physics aims to understand emergent properties of systems made of many interacting objects. This article reviews recent progress on the topic of radiative heat transfer i…
Inverse-designed photon extractors for optically addressable defect qubits
Srivatsa Chakravarthi, Pengning Chao, Christian Pederson +6
Solid-state defect qubit systems with spin-photon interfaces show great promise for quantum information and metrology applications. Photon collection efficiency, however, presents…
Channel-based algebraic limits to conductive heat transfer
Prashanth S. Venkataram, Sean Molesky, Juan Carlos Cuevas +1
Recent experimental advances probing coherent phonon and electron transport in nanoscale devices at contact have motivated theoretical channel-based analyses of conduction based on…
Mechanical relations between conductive and radiative heat transfer
Prashanth S. Venkataram, Riccardo Messina, Juan Carlos Cuevas +2
We present a general nonequilibrium Green's function formalism for modeling heat transfer in systems characterized by linear response that establishes the formal algebraic relation…
Fluctuational Electrodynamics in Atomic and Macroscopic Systems: van der Waals Interactions and Radiative Heat Transfer
Prashanth S. Venkataram, Jan Hermann, Alexandre Tkatchenko +1
We present an approach to describing fluctuational electrodynamic (FED) interactions, particularly van der Waals (vdW) interactions as well as radiative heat transfer (RHT), betwee…
