Kavli Affiliate: Taizan Watari | First 5 Authors: Masaki Okada, Taizan Watari, , , | Summary: A characterization of rational superconformal field theories (SCFTs) on 1+1 dimensions with Ricci-flat Kahler targets was proposed by S. Gukov and C. Vafa in terms of the Hodge structure of the target space. The article [arXiv:2205.10299] refined this idea […]
Kavli Affiliate: Sarah N. T. Heine | First 5 Authors: Joseph S. Adams, Robert Baker, Simon R. Bandler, Noemie Bastidon, Daniel Castro | Summary: The flight of the Micro-X sounding rocket on July 22, 2018 marked the first operation of Transition-Edge Sensors and their SQUID readouts in space. The instrument combines the microcalorimeter array with […]
Kavli Affiliate: Michael P. Brenner | First 5 Authors: Jacob Page, Peter Norgaard, Michael P. Brenner, Rich R. Kerswell, | Summary: A dynamical systems approach to turbulence envisions the flow as a trajectory through a high-dimensional state space transiently visiting the neighbourhoods of unstable simple invariant solutions (E. Hopf, Commun. Appl. Maths 1, 303, 1948). […]
Kavli Affiliate: Mohammad Mirhosseini | First 5 Authors: Chaitali Joshi, Frank Yang, Mohammad Mirhosseini, , | Summary: We demonstrate a superconducting artificial atom with strong unidirectional coupling to a microwave photonic waveguide. Our artificial atom is realized by coupling a transmon qubit to the waveguide at two spatially separated points with time-modulated interactions. Direction-sensitive interference […]
Kavli Affiliate: Leon Balents | First 5 Authors: Aleksandar Razpopov, David A. S. Kaib, Steffen Backes, Leon Balents, Stephen D. Wilson | Summary: Motivated by recent reports of a quantum disordered ground state in the triangular lattice compound NaRuO$_2$, we derive a $j_{rm eff}=1/2$ magnetic model for this system by means of first-principles calculations. The […]
Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Tamara Evstafyeva, Ulrich Sperhake, Thomas Helfer, Robin Croft, Miren Radia | Summary: We present a generalization of the curative initial data construction derived for equal-mass compact binaries in Helfer {it et al} (2019 Phys. Rev. D 99 044046; 2022 Class. Quantum Grav. 39 074001) to arbitrary mass […]
Kavli Affiliate: Timothy A. Ryan | Authors: Mukesh Kumar, Justin Knapp, Kallol Gupta and Timothy A Ryan | Summary: Recent advances have expanded the role of lipid droplets (LDs) beyond passive lipid storage, implicating their involvement in various metabolic processes across mammalian tissues. Neuronal LDs, long debated in existence, have been identified in several neural […]
Kavli Affiliate: Gary A. Steele | First 5 Authors: Ines C. Rodrigues, Gary A. Steele, Daniel Bothner, , | Summary: Harmonic oscillators belong to the most fundamental concepts in physics and are central to many current research fields such as circuit QED, cavity optomechanics and photon-pressure systems. Here, we engineer an effective negative mass harmonic […]

Steele, Daniel Bothner, , | Summary: Harmonic oscillators belong to the most fundamental concepts in physics and are central to many current research fields such as circuit QED, cavity optomechanics and photon-pressure systems. Here, we engineer a microwave mode in a […]
Kavli Affiliate: Gary A. Steele | First 5 Authors: Byoung-moo Ann, Sercan Deve, Gary A. Steele, , | Summary: Microwave driving is a ubiquitous technique for superconducting qubits (SCQs), but the dressed states description based on the conventionally used perturbation theory cannot fully capture the dynamics in the strong driving limit. Comprehensive studies beyond these […]
