Singlet and triplet Cooper pair splitting in hybrid superconducting nanowires

Kavli Affiliate: Michael Wimmer | First 5 Authors: Guanzhong Wang, Tom Dvir, Grzegorz P. Mazur, Chun-Xiao Liu, Nick van Loo | Summary: In most naturally occurring superconductors, electrons with opposite spins are paired up to form Cooper pairs. This includes both conventional $s$-wave superconductors such as aluminum as well as high-$T_text{c}$, $d$-wave superconductors. Materials with […]

The R-Process Alliance: A Nearly Complete R-Process Abundance Template Derived from Ultraviolet Spectroscopy of the R-Process-Enhanced Metal-Poor Star HD 222925

Kavli Affiliate: Anna Frebel | First 5 Authors: Ian U. Roederer, James E. Lawler, Elizabeth A. Den Hartog, Vinicius M. Placco, Rebecca Surman | Summary: We present a nearly complete rapid neutron-capture process (r-process) chemical inventory of the metal-poor ([Fe/H] = -1.46 +/- 0.10) r-process-enhanced ([Eu/Fe] = +1.32 +/- 0.08) halo star HD 222925. This […]

Gravothermal solutions of SIDM halos: mapping from constant to velocity-dependent cross section

Shengqi Yang, Xiaolong Du, Zhichao Carton Zeng, Andrew Benson, Fangzhou Jiang | Summary: [[{“value”:”The scale-free gravothermal fluid formalism has long proved effective in describing the evolution of self-interacting dark matter halos with a constant dark matter particle cross section. However, whether the gravothermal fluid solutions match numerical simulations for velocity-dependent cross-section scenarios remains untested. In […]

Hermitian Nonlinear Wave Mixing Controlled by a PT-Symmetric Phase Transition

Kavli Affiliate: Jeffrey Moses | First 5 Authors: Noah Flemens, Jeffrey Moses, , , | Summary: While non-Hermitian systems are normally constructed through incoherent coupling to a larger environment, recent works have shown that under certain conditions coherent couplings can be used to similar effect. We show that this new paradigm enables the behavior associated […]

Kepler K2 and TESS observations of two magnetic cataclysmic variables: The new asynchronous polar SDSS J084617.11+245344.1 and Paloma

Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Colin Littlefield, D. W. Hoard, Peter Garnavich, Paula Szkody, Paul A. Mason | Summary: There have been relatively few published long-duration, uninterrupted light curves of magnetic cataclysmic variable stars in which the accreting white dwarf’s rotational frequency is slightly desynchronized from the binary orbital frequency (asynchronous […]

Intrinsic spin Hall torque in a moire Chern magnet

Kavli Affiliate: Jie Shan | First 5 Authors: C. L. Tschirhart, Evgeny Redekop, Lizhong Li, Tingxin Li, Shengwei Jiang | Summary: In spin torque magnetic memories, electrically actuated spin currents are used to switch a magnetic bit. Typically, these require a multilayer geometry including both a free ferromagnetic layer and a second layer providing spin […]

Proximity-Induced Superconductivity in Epitaxial Topological Insulator/Graphene/Gallium Heterostructures

Kavli Affiliate: Ke Wang | First 5 Authors: Cequn Li, Yi-Fan Zhao, Alexander Vera, Omri Lesser, Hemian Yi | Summary: The introduction of superconductivity to the Dirac surface states of a topological insulator leads to a novel state of matter known as a topological superconductor. A topological superconductor may host Majorana zero modes, the braiding […]
