Large isotropic negative thermal expansion above a structural quantum phase transition
Sahan U. Handunkanda, Erin B. Curry, Vladimir Voronov +5
Perovskite structured materials contain myriad tunable ordered phases of electronic and magnetic origin with proven technological importance and strong promise for a variety of ene…
Performance and structure of single-mode bosonic codes
Victor V. Albert, Kyungjoo Noh, Kasper Duivenvoorden +9
The early Gottesman, Kitaev, and Preskill (GKP) proposal for encoding a qubit in an oscillator has recently been followed by cat- and binomial-code proposals. Numerically optimized…
Landau theory and giant room-temperature barocaloric effect in MF metal trifluorides
A. Corrales-Salazar, R. T. Brierley, P. B. Littlewood +1
The structural phase transitions of MF (M=Al, Cr, V, Fe, Ti, Sc) metal trifluorides are studied within a simple Landau theory consisting of tilts of rigid MF octahedra asso…
Cooperative elastic fluctuations provide tuning of the metal-insulator transition
G. G. Guzmán-Verri, R. T. Brierley, P. B. Littlewood
Metal to insulator transitions (MITs) driven by strong electronic correlations are common in condensed matter systems, and are associated with some of the most remarkable collectiv…
A fluxonium-based artificial molecule with a tunable magnetic moment
A. Kou, W. C. Smith, U. Vool +6
Engineered quantum systems allow us to observe phenomena that are not easily accessible naturally. The LEGO-like nature of superconducting circuits makes them particularly suited f…
Accelerating dark-matter axion searches with quantum measurement technology
Huaixiu Zheng, Matti Silveri, R. T. Brierley +2
The axion particle, a consequence of an elegant hypothesis that resolves the strong-CP problem of quantum chromodynamics, is a plausible origin for cosmological dark matter. In sea…
Implementing and characterizing precise multi-qubit measurements
J. Z. Blumoff, K. Chou, C. Shen +12
There are two general requirements to harness the computational power of quantum mechanics: the ability to manipulate the evolution of an isolated system and the ability to faithfu…
Signatures of quantum phase transitions in the dynamic response of fluxonium qubit chains
Hendrik Meier, R. T. Brierley, Angela Kou +2
We evaluate the microwave admittance of a one-dimensional chain of fluxonium qubits coupled by shared inductors. Despite its simplicity, this system exhibits a rich phase diagram.…
Domain wall fluctuations in ferroelectrics coupled to strain
R. T. Brierley, P. B. Littlewood
Using a Ginzburg--Landau--Devonshire model that includes the coupling of polarization to strain, we calculate the fluctuation spectra of ferroelectric domain walls. The influence o…
Adiabatic state preparation of interacting two-level systems
R. T. Brierley, C. Creatore, P. B. Littlewood +1
We consider performing adiabatic rapid passage (ARP) using frequency-swept driving pulses to excite a collection of interacting two-level systems. Such a model arises in a wide ran…
Creation of entangled states in coupled quantum dots via adiabatic rapid passage
Celestino Creatore, Richard T. Brierley, Richard T. Phillips +2
Quantum state preparation through external control is fundamental to established methods in quantum information processing and in studies of dynamics. In this respect, excitons in…
Amplitude-mode dynamics of polariton condensates
R. T. Brierley, P. B. Littlewood, P. R. Eastham
We study the stability of collective amplitude excitations in non-equilibrium polariton condensates. These excitations correspond to renormalized upper polaritons and to the collec…
Finite momentum condensation in a pumped microcavity
R. T. Brierley, P. R. Eastham
We calculate the absorption spectra of a semiconductor microcavity into which a non-equilibrium exciton population has been pumped. We predict strong peaks in the spectrum correspo…
