Kavli Affiliate: Robert Edwards | Authors: Joel E Brame, Craig Liddicoat, Catherine A Abbott, Robert A Edwards, Jake M Robinson, Nicolas E Gauthier and Martin F Breed | Summary: Butyrate-producing bacteria are found in many ecosystems and organisms, including humans, and are vital to ecosystem functionality and human health. These bacteria ferment organic matter, producing […]
Kavli Affiliate: Grace Xing | First 5 Authors: Len van Deurzen, Jashan Singhal, Jimy Encomendero, Naomi Pieczulewski, Celesta Chang | Summary: Using low-temperature cathodoluminescence spectroscopy, we study the properties of N- and Al-polar AlN layers grown by molecular beam epitaxy on bulk AlN{0001}. Compared to the bulk AlN substrate, layers of both polarities feature a […]

Kavli Affiliate: Srijit Goswami | First 5 Authors: Prasanna Rout, Nikos Papadopoulos, Fernando Peñaranda, Kenji Watanabe, Takashi Taniguchi | Summary: Bilayer graphene encapsulated in tungsten diselenide can host a weak topological phase with pairs of helical edge states. The electrical tunability of this phase makes it an ideal platform to investigate unique topological effects at […]

Kavli Affiliate: Leon Balents | First 5 Authors: Ethan C. McGarrigle, Kris T. Delaney, Leon Balents, Glenn H. Fredrickson, | Summary: We report the first numerical prediction of a "spin microemulsion" — a phase with undulating spin domains resembling classical bicontinuous oil-water-surfactant emulsions — in two-dimensional systems of spinor Bose-Einstein condensates with isotropic Rashba spin-orbit […]

Kavli Affiliate: Leon Balents | First 5 Authors: Ethan C. McGarrigle, Kris T. Delaney, Leon Balents, Glenn H. Fredrickson | Summary: Recent experiments have shown how the interplay between Bose statistics and spin-orbit coupling (SOC) can lead to superfluid liquid crystalline (stripe) analogues in cold atomic gases. For isotropic SOC in two spatial dimensions, a […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Shubh Agrawal, Jean-Baptiste Ruffio, Quinn M. Konopacky, Bruce Macintosh, Dimitri Mawet | Summary: While radial velocity surveys have demonstrated that the population of gas giants peaks around $3~text{au}$, the most recent high-contrast imaging surveys have only been sensitive to planets beyond $sim~10~text{au}$. Sensitivity at small angular separations […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Meer Ashwinkumar, Jacob M. Leedom, Masahito Yamazaki, , | Summary: We discuss interrelations between several ideas in quantum gravity. One is the Swampland program, which states that a low-energy effective field theory should satisfy non-trivial constraints to have an ultraviolet (UV) completion in quantum gravity. Another is […]
