Robust All-Electron Optimization in Orbital-Free Density Functional Theory Using the Trust Region Image Method
Matthew S. Ryley, Michael Withnall, Tom J. P. Irons +2
We present a Gaussian-basis implementation of orbital-free density-functional theory (OF-DFT) in which the trust-region image method (TRIM) is used for optimization. This second-or…
Multi-Photon Resonances in Josephson Junction-Cavity Circuits
Ben Lang, Andrew D. Armour
We explore the dissipative dynamics of nonlinearly driven oscillator systems tuned to resonances where multiple excitations are generated. Such systems are readily realised in circ…
Adiabatic Sensing Technique for Optimal Temperature Estimation using Trapped Ions
Aleksandrina V. Kirkova, Weibin Li, Peter A. Ivanov
We propose an adiabatic method for optimal phonon temperature estimation using trapped ions which can be operated beyond the Lamb-Dicke regime. The quantum sensing technique relies…
On quantum -Toda chain
A. A. Gerasimov, D. R. Lebedev, S. V. Oblezin
The orthosymplectic super Lie algebra is the closest analog of standard Lie algebras in the world of super Lie algebras. We demonstrate that the corresp…
Quantum estimation of coupling strengths in driven-dissipative optomechanics
Kamila Sala, Anton Doicin, Andrew D. Armour +1
We exploit local quantum estimation theory to investigate the measurement of linear and quadratic coupling strengths in a driven-dissipative optomechanical system. For experimental…
Dark Energy Survey Year 3 Results: Clustering Redshifts -- Calibration of the Weak Lensing Source Redshift Distributions with redMaGiC and BOSS/eBOSS
M. Gatti, G. Giannini, G. M. Bernstein +94
We present the calibration of the Dark Energy Survey Year 3 (DES Y3) weak lensing source galaxy redshift distributions from clustering measurements. In particular, we cross-…
