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

Posted by klaurent UCSB

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 […]

The Supersonic Project: Star Formation in Early Star Clusters without Dark Matter

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: William Lake, Smadar Naoz, Federico Marinacci, Blakesley Burkhart, Mark Vogelsberger | Summary: The formation mechanism of globular clusters (GCs) has long been debated by astronomers. It was recently proposed that Supersonically Induced Gas Objects (SIGOs), which formed in the early Universe due to the supersonic relative motion […]

JWST-JADES. Possible Population III signatures at z=10.6 in the halo of GN-z11

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Roberto Maiolino, Hannah Uebler, Michele Perna, Jan Scholtz, Francesco D’Eugenio | Summary: Finding the first generation of stars formed out of pristine gas in the early Universe, known as Population III (PopIII) stars, is one of the most important goals of modern astrophysics. Recent models have suggested […]

Cross-Modal Representation of Identity in Primate Hippocampus

Posted by klaurent UCSD / Salk

Kavli Affiliate: Cory Miller | Authors: Timothy Tyree, Michael Metke and Cory Miller | Summary: Faces and voices are the dominant social signals used to recognize individuals amongst human and nonhuman primates (1–4). Yet it is not known how these critical signals are integrated into a cross-modal representation of individual identity in the primate brain. […]

Imaging Moiré Excited States with Photocurrent Tunneling Microscopy

Posted by klaurent Berkeley

Kavli Affiliate: Alex Zettl | First 5 Authors: Hongyuan Li, Ziyu Xiang, Mit H. Naik, Woochang Kim, Zhenglu Li | Summary: Moir’e superlattices provide a highly tunable and versatile platform to explore novel quantum phases and exotic excited states ranging from correlated insulators1-17 to moir’e excitons7-10,18. Scanning tunneling microscopy has played a key role in […]

Precise measurement of the $D^+_s$ lifetime at Belle II

Posted by dbos Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Aihara, N. Akopov | Summary: We measure the lifetime of the $D_s^+$ meson using a data sample of 207 fb$^{-1}$ collected by the Belle II experiment running at the SuperKEKB asymmetric-energy $e^+ e^-$ collider. The lifetime is determined by […]

Ambarzumyan-type theorem for the Sturm-Liouville operator on the lasso graph

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Chuan-Fu Yang | Summary: We consider the Sturm-Liouville operator on the lasso graph with a segment and a loop joined at one point, which has arbitrary length. The Ambarzumyan’s theorem for the operator is proved, which says that if the eigenvalues of the operator coincide […]

Unravelling the Dust Attenuation Scaling Relations and their Evolution

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Gabriel Maheson, Roberto Maiolino, Mirko Curti, Ryan Sanders, Sandro Tacchella | Summary: We explore the dependence of dust attenuation, as traced by the $rm H_{alpha}/rm H_{beta}$ Balmer decrement, on galactic properties by using a large sample of SDSS spectra. We use both Partial Correlation Coefficients (PCC) and […]
