Kavli Affiliate: Adam S. Charles | Authors: Michael E. Xie, Johannes Friedrich, Elizabeth Wirsching, Caleb Jones Shibu, Maedeh Seyedolmohadesin, Naveen Ouellette, Tim Wang, Karel Svoboda, Adam S Charles and Kaspar Podgorski | Summary: Recent advances in fluorescent indicators and optical microscopy now enable in vivo synaptic imaging of glutamate, which transmits the majority of signals between neurons […]
Kavli Affiliate: Cynthia F. Moss | Authors: Nikita M Finger, Shivam S Chitnis, Grace Capshaw, Alara Kaplanoglu, Anand Krishnan and Cynthia F Moss | Summary: When sensory modalities yield conflicting information, animals must rapidly reassess stimuli to select their actions. We induced auditory–visual conflict in free-flying echolocating Egyptian fruit bats, by fitting animals with prisms […]
Kavli Affiliate: Clifford Kentros | Authors: Lucie A.L. Descamps, Wesley P. Clawson, Miguel M. Carvalho, Thomas Rogerson, Omer Hazon, Oscar M.T. Chadney, Mark J. Schnitzer and Clifford Kentrosa | Summary: Remembering object locations is crucial for survival, yet how the anterior cingulate cortex (ACC) encodes spatial features across repeated experiences has not been fully characterized. […]

Kavli Affiliate: Ralf Heilmann | Summary:The Rocket Experiment Demonstration of a Soft X-ray Polarimeter (REDSoX) is a NASA sounding-rocket mission designed to perform the first astrophysical spectropolarimetry in the 0.2-0.4 keV energy band. The instrument uses critical-angle transmission (CAT) gratings to disperse incident X-rays onto laterally graded multilayer (LGML) mirrors, requiring 48 individual gratings to […]
Kavli Affiliate: Huajia Wang | Summary:In theoretical physics, finding connections between problems that appear in distinct contexts is an important way to leapfrog progresses, often by illuminating deep aspects that may otherwise seem obscure. In this paper, we consider in 2d CFTs the phenomenon of forbidden singularities in auto-correlation functions — a key signature of […]
Kavli Affiliate: Huajia Wang | Summary:As phase transitions in isolated quantum systems remain elusive, here we show how a thermodynamic-like phase transition, falling into the Lee-Yang paradigm, can arise in systems displaying eigenstate thermalization. Specifically, we show that in holographic conformal field theories, the eigenstate expectation of the auto-correlation function can be mapped to the […]
Kavli Affiliate: Saul Rappaport | Summary:In this work we identify and photodynamically analyze TIC 433545934, the very first doubly eclipsing 2+2-type quadruple stellar system, which shows outer eclipses, too. One such outer eclipse was discovered with TESS, which triggered a special interest in this system. Most of the data for this study come from TESS […]
Kavli Affiliate: Mikhail Kapranov | Summary:In 1972, M. Sato proposed an approach to proving modularity of forms like Thetanullwerte by characterizing them via certain differential operators of infinite order (DOI) in the modular variable(s) alone. A DOI is an infinite series in derivatives decreasing so fast that it acts on holomorphic functions by a sheaf […]
Kavli Affiliate: Birgitta Whaley | Summary:Quantum subspace diagonalization methods are promising algorithms for quantum chemistry on near-term quantum computers. These methods can estimate low-lying energies of molecular systems using shallow quantum circuits, at the cost of many circuit repetitions to estimate the projected matrix elements. Errors in these matrix elements can be converted into much […]
