Realization of two-sublattice exchange physics in the triangular lattice compound Ba3Er(BO3)3

Posted by klaurent June 4, 2023UCSB

Kavli Affiliate: Leon Balents | First 5 Authors: Matthew Ennis, Rabindranath Bag, Chunxiao Liu, Sachith E. Dissanayake, Alexander I. Kolesnikov | Summary: We have synthesized high-quality single crystal samples of the erbium-based triangular lattice compound Ba3Er(BO3)3. Thermal and magnetic measurements reveal large anisotropy and a possible phase transition at 100 mK. The low-temperature magnetic heat […]

Manipulating chiral-spin transport with ferroelectric polarization

Posted by klaurent June 3, 2023Cornell

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Xiaoxi Huang, Xianzhe Chen, Yuhang Li, John Mangeri, Hongrui Zhang | Summary: A collective excitation of the spin structure in a magnetic insulator can transmit spin-angular momentum with negligible dissipation. This quantum of a spin wave, introduced more than nine decades ago, has always been manipulated […]

Excitations of quantum Ising chain CoNb2O6 in low transverse field: quantitative description of bound states stabilized by off-diagonal exchange and applied field

Posted by dbos June 2, 2023UCSB

Kavli Affiliate: Leon Balents | First 5 Authors: Leonie Woodland, Izabella Lovas, M. Telling, D. Prabhakaran, Leon Balents | Summary: We present experimental and theoretical evidence of novel bound state formation in the low transverse field ordered phase of the quasi-one-dimensional Ising-like material CoNb$_2$O$_6$. High resolution single crystal inelastic neutron scattering measurements observe that small […]

The Supersonic Project: Star Formation in Early Star Clusters without Dark Matter

Posted by klaurent June 1, 2023MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: William Lake, Smadar Naoz, Federico Marinacci, Blakesley Burkhart, Mark Vogelsberger | Summary: The formation mechanism of globular clusters (GCs) has long been debated by astronomers. It was recently proposed that Supersonically Induced Gas Objects (SIGOs), which formed in the early Universe due to the supersonic relative motion […]
