Bifurcation instructed design of multistate machines

Kavli Affiliate: Paul McEuen | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: We propose a novel design paradigm for multistate machines where transitions from one state to another are organized by bifurcations of multiple equilibria of the energy landscape describing the collective interactions of the machine components. This design paradigm is attractive […]

Molecular Beam Epitaxy of KTaO$_3$

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Strain-engineering is a powerful means to tune the polar, structural, and electronic instabilities of incipient ferroelectrics. KTaO3 is near a polar instability and shows anisotropic superconductivity in electron-doped samples. Here, we demonstrate growth of high quality KTaO3 thin films […]

Discontinuous metric programming in liquid crystalline elastomers

Kavli Affiliate: Itai Cohen | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Liquid crystalline elastomers (LCEs) are shape-changing materials that exhibit large deformations in response to applied stimuli. Local control of the orientation of LCEs spatially directs the deformation of these materials to realize spontaneous shape change in response to stimuli. Prior […]

Observation of suppressed viscosity in the normal state of $^3$He due to superfluid fluctuations

Kavli Affiliate: Jeevak M. Parpia | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: We have observed a fluctuation-driven reduction in the viscosity of bulk $^3$He in the normal state near the superfluid transition. While fluctuations are ubiquitous in two dimensional superconducting materials, in three dimensions fluctuations are thought to be limited to […]

Silicon-doped $β$-Ga$_2$O$_3$ films grown at 1 $μ$m/h by suboxide molecular-beam epitaxy

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: We report the use of suboxide molecular-beam epitaxy (S-MBE) to grow $beta$-Ga$_2$O$_3$ at a growth rate of ~1 ${mu}$m/h with control of the silicon doping concentration from 5×10$^{16}$ to 10$^{19}$ cm$^{-3}$. In S-MBE, pre-oxidized gallium in the form of […]

Extending the Use of Information Theory in Segregation Analyses to Construct Comprehensive Models of Segregation

Kavli Affiliate: Itai Cohen | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: The traditional approach to the quantitative study of segregation is to employ indices that are selected by “desirable properties”. Here, we detail how information theory underpins entropy-based indices and demonstrate how desirable properties can be used to systematically construct models […]

Strong photon-magnon coupling using a lithographically defined organic ferrimagnet

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: We demonstrate a hybrid quantum system composed of superconducting resonator photons and magnons hosted by the organic-based ferrimagnet vanadium tetracyanoethylene (V[TCNE]$_x$). Our work is motivated by the challenge of scalably integrating an arbitrarily-shaped, low-damping magnetic system with planar superconducting […]

Real-space imaging of polar and elastic nano-textures in thin films via inversion of diffraction data

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Exploiting the emerging nanoscale periodicities in epitaxial, single-crystal thin films is an exciting direction in quantum materials science: confinement and periodic distortions induce novel properties. The structural motifs of interest are ferroelastic, ferroelectric, multiferroic, and, more recently, topologically protected […]
