Modelling of planar germanium hole qubits in electric and magnetic fields

Posted by dbos Delft

Kavli Affiliate: Menno Veldhorst | First 5 Authors: Chien-An Wang, Ercan Ekmel, Mark Gyure, Giordano Scappucci, Menno Veldhorst | Summary: Hole-based spin qubits in strained planar germanium quantum wells have received considerable attention due to their favourable properties and remarkable experimental progress. The sizeable spin-orbit interaction in this structure allows for efficient qubit operations with […]

Ultra-bright Coherent Undulator Radiation Driven by Dielectric Laser Accelerator

Posted by dbos Stanford

Kavli Affiliate: Robert L. Byer | First 5 Authors: Yen-Chieh Huang, Robert L. Byer, , , | Summary: A dielectric laser accelerator, operating at optical frequencies and GHz pulse rate, is expected to produce attosec electron bunches with a moderate beam current at high energy. For relativistic electrons, the attosec bunch has a spatial length […]

A Stress Induced Source of Phonon Bursts and Quasiparticle Poisoning

Posted by dbos Stanford

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 […]

Monojet signatures from gluino and squark decays

Posted by dbos Tokyo

Kavli Affiliate: Mihoko M. Nojiri | First 5 Authors: Iñaki Lara, Trygve Buanes, Rafał Masełek, Mihoko M. Nojiri, Krzysztof Rolbiecki | Summary: We study the monojet and dijet channels at the LHC as a tool for searching for squarks and gluinos. We consider two separate R-parity conserving supersymmetric scenarios. In the first scenario we postulate […]

Multimode Nonlinear Dynamics in Anomalous Dispersion Spatiotemporal Mode-locked Lasers

Posted by dbos Cornell

Kavli Affiliate: Frank W. Wise | First 5 Authors: Yuhang Wu, Demetrios N. Christodoulides, Frank W. Wise, , | Summary: Spatiotemporal mode-locking in a laser with anomalous dispersion is investigated. Mode-locked states with varying modal content can be observed, but we find it difficult to observe highly multimode states. We describe the properties of these […]
