Kavli Affiliate: Leon Balents | First 5 Authors: Takamori Park, Leon Balents, , , | Summary: Inspired by the recent work by Delacretaz et. al., we rigorously derive an exact and simple method to bosonize a non-interacting fermionic system with a Fermi surface starting from a microscopic Hamiltonian. In the long-wavelength limit, we show that […]

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 […]

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Francesco Serafin, Mark J. Bowick, , , | Summary: Using the proof of Willmore’s conjecture by Marques and Neves, we conjecture that the free energy of tensionless fluid membranes of arbitrary genus has an upper bound. This implies that the average genus of such a membrane, […]
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 […]

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 […]
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 […]
