Quantum $z=2$ Lifshitz criticality in one-dimensional interacting fermions

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, , , , | Summary: We consider Lifshitz criticality (LC) with the dynamical critical exponent $z=2$ in one-dimensional interacting fermions with a filled Dirac Sea. We report that interactions have crucial effects on Lifshitz criticality. Single particle excitations are destabilized by interaction and decay into […]

A frontosensory circuit for visual context processing is synchronous in the theta/alpha band

Kavli Affiliate: Darcy Peterka | Authors: Georgia Bastos, Jacob T Holmes, Jordan M Ross, Anna M Rader, Connor G Gallimore, Darcy S Peterka and Jordan P Hamm | Summary: Visual processing is strongly influenced by context. Stimuli that deviate from contextual regularities elicit augmented responses in primary visual cortex (V1). These heightened responses, known as […]

Unusual Hard X-ray Flares Caught in NICER Monitoring of the Binary Supermassive Black Hole Candidate AT2019cuk/Tick Tock/SDSS J1430+2303

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Megan Masterson, Erin Kara, Dheeraj R. Pasham, Daniel J. D’Orazio, Dominic J. Walton | Summary: The nuclear transient AT2019cuk/Tick Tock/SDSS J1430+2303 has been suggested to harbor a supermassive black hole (SMBH) binary near coalescence. We report results from high-cadence NICER X-ray monitoring with multiple visits per […]

The interplay between accretion, galaxy downsizing and the formation of box/peanut bulges in TNG50

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Stuart Robert Anderson, Steven Gough-Kelly, Victor P. Debattista, Min Du, Peter Erwin | Summary: From the TNG50 cosmological simulation we build a sample of 191 well-resolved barred galaxies with a stellar mass $log M_star > 10$ at $z=0$. We search for box/peanut bulges (BPs) in this sample, […]

A Fiber-coupled Scanning Magnetometer with Nitrogen-Vacancy Spins in a Diamond Nanobeam

Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Yufan Li, Fabian A. Gerritsma, Samer Kurdi, Nina Codreanu, Simon Gröblacher | Summary: Magnetic imaging with nitrogen-vacancy (NV) spins in diamond is becoming an established tool for studying nanoscale physics in condensed matter systems. However, the optical access required for NV spin readout remains an […]

Employing High-temperature-grown SrZrO$_3$ Buffer to Enhance the Electron Mobility in La:BaSnO$_3$-based Heterostructures

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Prosper Ngabonziza, Jisung Park, Wilfried Sigle, Peter A. van Aken, Jochen Mannhart | Summary: We report a synthetic route to achieve high electron mobility at room temperature in epitaxial La:BaSnO$_3$/SrZrO$_3$ heterostructures prepared on several oxide substrates. Room-temperature mobilities of 157, 145, and 143 cm$^2$V$^{-1}$s$^{-1}$ are achieved […]

Wet Compaction to a Blue Nugget: a Critical Phase in Galaxy Evolution

Sharon Lapiner, Avishai Dekel, Jonathan Freundlich, Omri Ginzburg, Fangzhou Jiang | Summary: [[{“value”:”We utilize high-resolution cosmological simulations to reveal that high-redshift galaxies tend to undergo a robust `wet compaction’ event when near a `golden’ stellar mass of $sim 10^{10} M_{odot}$. This is a gaseous shrinkage to a compact star-forming phase, a `blue nugget’ (BN), followed […]
