Observation of suppressed viscosity in the normal state of $^3$He due to superfluid fluctuations

Kavli Affiliate: Jeevak M. Parpia | First 5 Authors: Rakin N. Baten, Yefan Tian, Eric N. Smith, Erich Mueller, Jeevak M. Parpia | Summary: By monitoring the quality factor of a quartz tuning fork oscillator we have observed a fluctuation-driven reduction in the viscosity of bulk $^3$He in the normal state near the superfluid transition […]

Recurrent flow patterns as a basis for turbulence: predicting statistics from structures

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). […]

Resonance fluorescence of a chiral artificial atom

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 […]

Continuous Trajectory Optimization via B-splines for Multi-jointed Robotic Systems

Kavli Affiliate: Ting Xu | First 5 Authors: Changhao Wang, Ting Xu, Masayoshi Tomizuka, , | Summary: Continuous formulations of trajectory planning problems have two main benefits. First, constraints are guaranteed to be satisfied at all times. Secondly, dynamic obstacles can be naturally considered with time. This paper introduces a novel B-spline based trajectory optimization […]

Resolving non-perturbative renormalization of a microwave-dressed weakly anharmonic superconducting qubit

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 […]
