Kavli Affiliate: Ankit Disa | First 5 Authors: Ankit S. Disa, Alexandru B. Georgescu, James L. Hart, Divine P. Kumah, Padraic Shafer | Summary: The combination of charge and spin degrees of freedom with electronic correlations in condensed matter systems leads to a rich array of phenomena, such as magnetism, superconductivity, and novel conduction mechanisms. […]
Kavli Affiliate: Nathan Lewis | First 5 Authors: N. K. Lewis, P. J. Durham, W. R. Flavell, E. A. Seddon, | Summary: Two-dimensional hexagonal and oblique lattices were investigated theoretically with the aim of observing differences in the spin expectation values between chiral and achiral systems. The spinresolved band structures were derived from the energy […]
Kavli Affiliate: Thomas M. Crawford | First 5 Authors: John E. Carlstrom, Thomas M. Crawford, Lloyd Knox, , | Summary: Temperature and polarization variations across the microwave sky include the fingerprints of quantum fluctuations in the early universe. They may soon reveal physics at unprecedented energy scales. | Search Query: arXiv Query: search_query=au:”Thomas M. Crawford”&id_list=&start=0&max_results=3 […]
Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, , , , | Summary: It is suggested that the exact value of the cosmological constant could be derived from first principles, based on entanglement of the Standard Model field vacuum with emergent holographic quantum geometry. For the observed value of the cosmological constant, geometrical […]

Kavli Affiliate: Jinyi Shangguan | First 5 Authors: Jinyi Shangguan, Luis C. Ho, Yanxia Xie, , | Summary: The interstellar medium is crucial to understanding the physics of active galaxies and the coevolution between supermassive black holes and their host galaxies. However, direct gas measurements are limited by sensitivity and other uncertainties. Dust provides an […]
Kavli Affiliate: Alexander Ji | First 5 Authors: Alexander P. Ji, Anna Frebel, , , | Summary: The ultra-faint dwarf galaxy Reticulum II was enriched by a rare and prolific r-process event, such as a neutron star merger. To investigate the nature of this event, we present high-resolution Magellan/MIKE spectroscopy of the brightest star in […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Gordan Krnjaic, , , , | Summary: Freeze-in dark matter (DM) mediated by a light ($ll$ keV) weakly-coupled dark-photon is an important benchmark for the emerging low-mass direct detection program. Since this is one of the only predictive, detectable freeze-in models, we investigate how robustly such testability […]
Kavli Affiliate: Savdeep Sethi | First 5 Authors: Savdeep Sethi, , , , | Summary: Type II string theory and M-theory admit flux configurations that break supersymmetry below the Kaluza-Klein scale. These backgrounds play a central role in most models of the string landscape. I argue that the behavior of such backgrounds at weak coupling […]
Kavli Affiliate: Jeffrey John McMahon | First 5 Authors: Sean Bryan, Peter Ade, J. Richard Bond, Francois Boulanger, Mark Devlin | Summary: BFORE is a NASA high-altitude ultra-long-duration balloon mission proposed to measure the cosmic microwave background (CMB) across half the sky during a 28-day mid-latitude flight launched from Wanaka, New Zealand. With the unique […]
