Kavli Affiliate: Feng Wang | First 5 Authors: Ruishi Qi, Andrew Y. Joe, Zuocheng Zhang, Jingxu Xie, Qixin Feng | Summary: Strongly coupled two-dimensional electron-hole bilayers can give rise to novel quantum Bosonic states: electrons and holes in electrically isolated layers can pair into interlayer excitons, which can form a Bose-Einstein condensate below a critical […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aklant K Bhowmick, Laura Blecha, Paul Torrey, Rainer Weinberger, Luke Zoltan Kelley | Summary: The nature of the first seeds of supermassive black holes (SMBHs) is currently unknown, with postulated initial masses ranging from $sim10^5~M_{odot}$ to as low as $sim10^2~M_{odot}$. However, most existing cosmological simulations resolve BHs […]
Kavli Affiliate: Stefano Fusi | Authors: Sean Chih-Hsiung Lim, Stefano Fusi and Rene Hen | Summary: The ventral hippocampus is a critical node in the distributed brain network that controls anxiety. Using miniature microscopy and calcium imaging, we recorded ventral CA1 (vCA1) neurons in freely moving mice as they explored variants of classic behavioral assays […]
Kavli Affiliate: Nicola Allen | Authors: Ashley N Brandebura, Quinn N Asbell, Mariel Kristine B Micael and Nicola J Allen | Summary: Neuronal dendrite structure and synapse formation is tightly regulated during development to promote proper connectivity. Astrocyte-secreted proteins act as guidance and pro-synaptogenic factors, and astrocyte protein secretion is dysregulated in neurodevelopmental disorders with […]

Kavli Affiliate: Tom Abel | First 5 Authors: William R. Coulton, Tom Abel, Arka Banerjee, , | Summary: Searches for primordial non-Gaussianity in cosmological perturbations are a key means of revealing novel primordial physics. However, robustly extracting signatures of primordial non-Gaussianity from non-linear scales of the late-time Universe is an open problem. In this paper, […]
Kavli Affiliate: Jie Shan | First 5 Authors: Phuong X. Nguyen, Liguo Ma, Raghav Chaturvedi, Kenji Watanabe, Takashi Taniguchi | Summary: Excitonic insulators (EIs), arising in semiconductors when the electron-hole binding energy exceeds the band gap, are a solid-state prototype for bosonic phases of matter. Unlike the charged excitations that are frozen and unable to […]
Kavli Affiliate: Robert F. Goeke | First 5 Authors: Melissa J. Hobson, Trifon Trifonov, Thomas Henning, Andrés Jordán, Felipe Rojas | Summary: We present the spectroscopic confirmation and precise mass measurement of the warm giant planet TOI-199 b. This planet was first identified in TESS photometry and confirmed using ground-based photometry from ASTEP in Antarctica […]

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, Will Barker, , | Summary: A variational principle for gauge theories of gravity is presented, which maintains manifest covariance under the symmetries to which the action is invariant, throughout the calculation of the equations of motion and conservation laws. This is performed by […]
