Inferring global dynamics from local structure in liquid electrolytes

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Penelope K. Jones, Kara D. Fong, Kristin A. Persson, Alpha A. Lee, | Summary: Ion transport in concentrated electrolytes plays a fundamental role in electrochemical systems such as lithium ion batteries. Nonetheless, the mechanism of transport amid strong ion-ion interactions remains enigmatic. A key question is […]

Non-Gaussianity effects on the primordial black hole abundance for sharply-peaked primordial spectrum

Kavli Affiliate: Misao Sasaki | First 5 Authors: Takahiko Matsubara, Misao Sasaki, , , | Summary: We perturbatively study the effect of non-Gaussianities on the mass fraction of primordial black holes (PBHs) at the time of formation by systematically taking its effect into account in the one-point probability distribution function of the primordial curvature perturbation. […]

A Stress Induced Source of Phonon Bursts and Quasiparticle Poisoning

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Robin Anthony-Petersen, Andreas Biekert, Raymond Bunker, Clarence L. Chang, Yen-Yung Chang | Summary: The performance of superconducting qubits is degraded by a poorly characterized set of energy sources breaking the Cooper pairs responsible for superconductivity, creating a condition often called “quasiparticle poisoning". Both superconducting qubits and low […]
