Extent of Fermi-surface reconstruction in the high-temperature superconductor HgBa$_2$CuO$_{4+δ}$

Kavli Affiliate: Brad J. Ramshaw | First 5 Authors: Mun K. Chan, Ross D. McDonald, Brad J. Ramshaw, Jon B. Betts, Arkady Shekhter | Summary: High magnetic fields have revealed a surprisingly small Fermi-surface in underdoped cuprates, possibly resulting from Fermi-surface reconstruction due to an order parameter that breaks translational symmetry of the crystal lattice. […]

Computational Synthesis of Substrates by Crystal Cleavage

Kavli Affiliate: Kyle Shen | First 5 Authors: Joshua T. Paul, Alice Galdi, Christopher Parzyck, Kyle Shen, Richard G. Hennig | Summary: The discovery of novel substrate materials has been dominated by trial and error, opening the opportunity for a systematic search. To identify stable crystal surfaces, we generate bonding networks for materials from the […]

Effect of Rough Walls on Transport in Mesoscopic $^3$He Films

Kavli Affiliate: Jeevak M. Parpia | First 5 Authors: Priya Sharma, Antonio Corcoles, R. G. Bennett, Jeevak M. Parpia, Brian Cowan | Summary: The interplay of bulk and boundary scattering is explored in a regime where quantum size effects modify mesoscopic transport in a degenerate Fermi liquid film of $^3$He on a rough surface. We […]

Elastic properties of hidden order in URu$_{text2}$Si$_{text2}$ are reproduced by a staggered nematic

Kavli Affiliate: Brad Ramshaw | First 5 Authors: Jaron Kent-Dobias, Michael Matty, Brad Ramshaw, , | Summary: We develop a phenomenological mean field theory describing the hidden order phase in URu$_{text2}$Si$_{text2}$ as a nematic of the $text B_{text{1g}}$ representation staggered along the $c$-axis. Several experimental features are reproduced by this theory: the topology of the […]

Dissipation-enabled hydrodynamic conductivity in a tunable bandgap semiconductor

Kavli Affiliate: Paul L. McEuen | First 5 Authors: Cheng Tan, Derek Y. H. Ho, Lei Wang, J. I. A. Li, Indra Yudhistira | Summary: Electronic transport in the regime where carrier-carrier collisions are the dominant scattering mechanism has taken on new relevance with the advent of ultraclean two-dimensional materials. Here we present a combined […]

Mesophase Formation Stabilizes High-Purity Magic-Sized Clusters

Kavli Affiliate: Richard D. Robinson | First 5 Authors: Douglas R. Nevers, Curtis B. Williamson, Benjamin H. Savitzky, Ido Hadar, Uri Banin | Summary: Magic-sized clusters (MSCs) are renowned for their identical size and closed-shell stability that inhibit conventional nanoparticle (NP) growth processes. Though MSCs have been of increasing interest, understanding the reaction pathways toward […]

Sr3CrN3: a new electride with partially filled d-shells

Kavli Affiliate: Jin Suntivich | First 5 Authors: Padtaraporn Chanhom, Kevin E. Fritz, Lee Burton, Jan Kloppenburg, Yaroslav Filinchuk | Summary: Electrides are ionic crystals in which the electrons prefer to occupy free space, serving as anions. Because the electrons prefer to be in the pockets, channels, or layers to the atomic orbitals around the […]
