Understanding Damping Mechanisms via Spin Diffusion Length in Low-damping LiAlFeO Spinel Ferrite Thin Films
Katya Mikhailova, Lerato Takana, Guanxiong Qu +5
The mechanisms underlying magnon damping are of fundamental and technological interest in low-damping materials. We find low-damping ferrimagnetic insulator LiAlFe$…
Low-temperature spin dynamics in LAFO thin films: from cubic anisotropy to TLS-limited coherence
Srishti Pal, Guanxiong Qu, Hervé M. Carruzzo +6
We investigate the low-temperature spin dynamics of epitaxial lithium aluminum ferrite (LAFO) thin films using broadband ferromagnetic resonance (FMR) spectroscopy from 0.44 K to 6…
Interacting Two-Level Systems as a Source of 1/f Charge Noise in Quantum Dot Qubits
D. L. Mickelsen, Herve M. Carruzzo, Clare C. Yu
Charge noise in semiconducting quantum dots has been observed to have a 1/f spectrum. We propose a model in which a pair of quantum dots are coupled to a 2D bath of fluctuating two…
Effects of Temperature Fluctuations on Charge Noise in Quantum Dot Qubits
Dan Mickelsen, Herve M. Carruzzo, Susan N. Coppersmith +1
Silicon quantum dot qubits show great promise but suffer from charge noise with a 1/f^αspectrum, where f is frequency and α\lesssim 1. It has recently been proposed that 1/f^αnoise…
Two-Level Systems and the Tunneling Model: A Critical View
Clare C. Yu, Hervé M. Carruzzo
The thermal and acoustic properties displayed by a wide variety of glasses at low temperatures are well described by the model of tunneling two level systems (TLS). We review the s…
Why phonon scattering in glasses is universally small at low temperatures
Herve M. Carruzzo, Clare C. Yu
We present a novel view of the standard model of tunneling two level systems (TLS) to explain the puzzling universal value of a quantity, , that characterize…
