Measuring photoexcited electron and hole dynamics in ZnTe and modeling excited state core-valence effects in transient XUV reflection spectroscopy

Posted by klaurent Caltech

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Hanzhe Liu, Jonathan M. Michelsen, Isabel M. Klein, Scott K. Cushing, | Summary: Transient XUV spectroscopy is growing in popularity for the measurement of solar fuel and photovoltaic materials as it can separately measure electron and hole energies for multiple elements at once. However, interpretation of […]

Topological Optical Parametric Oscillation

Posted by klaurent Caltech

Kavli Affiliate: Alireza Marandi | First 5 Authors: Arkadev Roy, Midya Parto, Rajveer Nehra, Christian Leefmans, Alireza Marandi | Summary: Topological insulators possess protected boundary states which are robust against disorders and have immense implications in both fermionic and bosonic systems. Harnessing these topological effects in non-equilibrium scenarios is highly desirable and has led to […]

Circuit quantum electrodynamics with two remote electron spins

Posted by klaurent Delft

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Patrick Harvey-Collard, Jurgen Dijkema, Guoji Zheng, Amir Sammak, Giordano Scappucci | Summary: We report the coherent coupling of two electron spins at a distance via virtual microwave photons. Each spin is trapped in a silicon double quantum dot at either end of a superconducting resonator, achieving spin-photon […]

Directional excitation of a high-density magnon gas using coherently driven spin waves

Posted by klaurent Delft

Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Brecht G. Simon, Samer Kurdi, Helena La, Iacopo Bertelli, Joris J. Carmiggelt | Summary: Controlling magnon densities in magnetic materials enables driving spin transport in magnonic devices. We demonstrate the creation of large, out-of-equilibrium magnon densities in a thin-film magnetic insulator via microwave excitation of […]

Two-photon sideband transition in a driven quantum Rabi model : Quantitative discussions with derived longitudinal drives and beyond the rotating wave approximation

Posted by klaurent Delft

Kavli Affiliate: Gary A. Steele | First 5 Authors: Byoung-moo Ann, Wouter Kessels, Gary A. Steele, , | Summary: In this work, we analytically and numerically study the sideband transition dynamics of the driven quantum Rabi model (QRM). We focus in particular on the conditions when the external transverse drive fields induce first-order sideband transitions. […]

Universal scaling of shear thickening transitions

Posted by klaurent Cornell

Kavli Affiliate: Itai Cohen | First 5 Authors: Meera Ramaswamy, Itay Griniasty, Danilo B. Liarte, Abhishek Shetty, Eleni Katifori | Summary: Nearly all dense suspensions undergo dramatic and abrupt thickening transitions in their flow behavior when sheared at high stresses. Such transitions occur when the dominant interactions between the suspended particles shift from hydrodynamic to […]

Mechanical Cloak via Data-Driven Aperiodic Metamaterial Design

Posted by Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Liwei Wang, Jagannadh Boddapati, Ke Liu, Ping Zhu, Chiara Daraio | Summary: Mechanical cloaks are materials engineered to manipulate the elastic response around objects to make them indistinguishable from their homogeneous surroundings. Typically, methods based on material-parameter transformations are used to design optical, thermal and electric cloaks. […]

Strong Negative Electrothermal Feedback in Thermal Kinetic Inductance Detectors

Posted by klaurent Caltech

Kavli Affiliate: James J. Bock | First 5 Authors: Shubh Agrawal, Bryan Steinbach, James J. Bock, Clifford Frez, Lorenzo Minutolo | Summary: We demonstrate strong negative electrothermal feedback accelerating and linearizing the response of a thermal kinetic inductance detector (TKID). TKIDs are a proposed highly multiplexable replacement to transition-edge sensors and measure power through the […]
