Kavli Affiliate: Leon Balents | First 5 Authors: Gu-Feng Zhang, Sheikh Rubaiat Ul Haque Kelson J. Kaj, Xiang Chen, Urban F. P. Seifert, Jingdi Zhang | Summary: Antiferromagnets exhibit rapid spin dynamics in a net zero magnetic background which enables novel spintronic applications and interrogation of many-body quantum phenomena. The layered antiferromagnet Sr$_2$IrO$_4$ hosts an […]
Kavli Affiliate: Mark J. Bowick | First 5 Authors: Jin-Sheng Wu, Roberto Abril Valenzuela, Mark J. Bowick, Ivan I. Smalyukh, | Summary: We study topologically stable defect structures in systems where the defect line classification in three dimensions and associated algebra of interactions (the fundamental group) are governed by the non-Abelian 8-element group, the quaternions […]
Kavli Affiliate: John E. Bowers | First 5 Authors: Shixin Xue, Mingxiao Li, Raymond Lopez-rios, Jingwei Ling, Zhengdong Gao | Summary: The invention of the laser unleashed the potential of optical metrology, leading to numerous advancements in modern science and technology. This reliance on lasers, however, also sets a bottleneck for precision optical metrology which […]
Kavli Affiliate: Leon Balents | First 5 Authors: Rimika Jaiswal, Izabella Lovas, Leon Balents, , | Summary: We propose a variational approach to explore quasiparticle excitations in interacting quantum many-body systems, motivated by the potential in leveraging near-term noisy intermediate scale quantum devices for quantum state preparation. By exploiting translation invariance and potentially other abelian […]

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 […]

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 […]
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, […]
