Spinon spin current

Kavli Affiliate: Leon Balents | First 5 Authors: Ren-Bo Wang, Naveen Nishad, Anna Keselman, Leon Balents, Oleg A. Starykh | Summary: We present the theory of the longitudinal spin Seebeck effect between a Heisenberg spin-1/2 chain and a conductor. The effect consists of the generation of a spin current across the spin chain-conductor interface in […]

Spin Excitation Continuum in the Exactly Solvable Triangular-Lattice Spin Liquid CeMgAl11O19

Kavli Affiliate: Leon Balents | First 5 Authors: Bin Gao, Tong Chen, Chunxiao Liu, Mason L. Klemm, Shu Zhang | Summary: In magnetically ordered insulators, elementary quasiparticles manifest as spin waves – collective motions of localized magnetic moments propagating through the lattice – observed via inelastic neutron scattering. In effective spin-1/2 systems where geometric frustrations […]

Controlling assembly and oscillations of elastic membranes with an active fluid

Kavli Affiliate: Mark Bowick | First 5 Authors: John Berezney, Sattvic Ray, Itamar Kolvin, Mark Bowick, Seth Fraden | Summary: We use the chaotic flows generated by a microtubule-based active fluid to assemble self-binding actin filaments into a thin elastic sheets. Starting from a uniformly dispersed state, active flows drive the motion of actin filaments, […]

Shocking and Mass Loss of Compact Donor Stars in Type Ia Supernovae

Kavli Affiliate: Lars Bildsten | First 5 Authors: Tin Long Sunny Wong, Christopher White, Lars Bildsten, , | Summary: Type Ia supernovae arise from thermonuclear explosions of white dwarfs accreting from a binary companion. Following the explosion, the surviving donor star leaves at roughly its orbital velocity. The discovery of the runaway helium subdwarf star […]
