The effect of the adiabatic assumption on asteroseismic scaling relations for luminous red giants

Kavli Affiliate: Lars Bildsten | First 5 Authors: Joel C. Zinn, Marc H. Pinsonneault, Lars Bildsten, Dennis Stello, | Summary: Although stellar radii from asteroseismic scaling relations agree at the percent level with independent estimates for main sequence and most first-ascent red giant branch stars, the scaling relations over-predict radii at the tens of percent […]

Mott insulators in moiré transition metal dichalcogenides at fractional fillings: Slave-rotor mean-field theory

Kavli Affiliate: Leon Balents | First 5 Authors: Zhenhao Song, Urban F. P. Seifert, Zhu-Xi Luo, Leon Balents, | Summary: In this work, we study a slave-rotor mean-field theory of an extended Hubbard model, applicable to transition metal dichalcogenide moir’e systems, that captures both the formation of Wigner crystals as well as exotic spin states […]

Geometric control of tilt transition dynamics in single-clamped thermalized elastic sheets

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Roberto Abril Valenzuela, Paul Z. Hanakata, Mark J. Bowick, , | Summary: We study the finite-temperature dynamics of thin elastic sheets in a single-clamped cantilever configuration. This system is known to exhibit a tilt transition at which the preferred mean plane of the sheet shifts from […]

Turbulence Supported Massive Star Envelopes

Kavli Affiliate: Lars Bildsten | First 5 Authors: William Schultz, Lars Bildsten, Yan-Fei Jiang, , | Summary: The outer envelopes of massive ($Mgtrsim10,M_{odot}$) stars exhibit large increases in opacities from forests of lines and ionization transitions (particularly from iron and helium) that trigger near-surface convection zones. One-dimensional models predict density inversions and supersonic motions that […]

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

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 […]

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

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 […]
