Electromagnetic properties of thin metallic films
Luke S. Langsjoen, Amrit Poudel, Maxim G. Vavilov +1
We compute the electromagnetic fluctuations due to evanescent-wave Johnson noise in the vicinity of a thin conducting film, such as a metallic gate or a 2-dimensional electron gas.…
Relaxation in quantum dots due to evanescent-wave Johnson noise from a metallic backgate
Amrit Poudel, Luke Langsjoen, Maxim Vavilov +1
We present our study of decoherence in charge (spin) qubits due to evanescent-wave Johnson noise (EWJN) in a laterally coupled double quantum dot (single quantum dot). The high den…
Qubit relaxation from evanescent-wave Johnson noise
Luke S. Langsjoen, Amrit Poudel, Maxim G. Vavilov +1
In many quantum computer architectures, the qubits are in close proximity to metallic device elements. Metals have a high density of photon modes, and the fields spill out of the b…
Weyl problem and Casimir effects in spherical shell geometry
Eugene B. Kolomeisky, Hussain Zaidi, Luke Langsjoen +1
We compute the generic mode sum that quantifies the effect on the spectrum of a harmonic field when a spherical shell is inserted into vacuum. This encompasses a variety of problem…
Casimir effect due to a single boundary as a manifestation of the Weyl problem
Eugene B. Kolomeisky, Joseph P. Straley, Luke S. Langsjoen +1
The Casimir self-energy of a boundary is ultraviolet-divergent. In many cases the divergences can be eliminated by methods such as zeta-function regularization or through physical…
