Enhancement of vibrationally assisted energy transfer by proximity to exceptional points, probed by fluorescence-detected vibrational spectroscopy

Posted by dbos Berkeley

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Zeng-Zhao Li, K. Birgitta Whaley, , , | Summary: Emulation of energy transfer processes in natural systems on quantum platforms can further our understanding of complex dynamics in nature. One notable example is the demonstration of vibrationally assisted energy transfer (VAET) on a trapped-ion quantum emulator, which […]

Optical absorption spectra of metal oxides from time-dependent density functional theory and many-body perturbation theory based on optimally-tuned hybrid functionals

Posted by klaurent Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Guy Ohad, Stephen E. Gant, Dahvyd Wing, Jonah B. Haber, María Camarasa-Gómez | Summary: Using both time-dependent density functional theory (TDDFT) and the “single-shot" $GW$ plus Bethe-Salpeter equation ($GW$-BSE) approach, we compute optical band gaps and optical absorption spectra from first principles for eight common binary […]

A Control Architecture for Entanglement Generation Switches in Quantum Networks

Posted by dbos Delft

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Scarlett Gauthier, Gayane Vardoyan, Stephanie Wehner, , | Summary: Entanglement between quantum network nodes is often produced using intermediary devices – such as heralding stations – as a resource. When scaling quantum networks to many nodes, requiring a dedicated intermediary device for every pair of nodes introduces […]

Topological synchronization of fractionalized spins

Posted by klaurent Berkeley

Kavli Affiliate: Joel E. Moore | First 5 Authors: Christopher W. Wächtler, Joel E. Moore, , , | Summary: The gapped symmetric phase of the Affleck-Kennedy-Lieb-Tasaki (AKLT) model exhibits fractionalized spins at the ends of an open chain. We show that breaking SU(2) symmetry and applying a global spin-lowering dissipator achieves synchronization of these fractionalized […]

Control of Mechanical and Fracture Properties in Two-phase Materials Reinforced by Continuous, Irregular Networks

Posted by klaurent Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Tommaso Magrini, Chelsea Fox, Adeline Wihardja, Athena Kolli, Chiara Daraio | Summary: Composites with high strength and high fracture resistance are desirable for structural and protective applications. Most composites, however, suffer from poor damage tolerance and are prone to unpredictable fractures. Understanding the behavior of materials with […]

High-resolution, large field-of-view label-free imaging via aberration-corrected, closed-form complex field reconstruction

Posted by klaurent Caltech

Kavli Affiliate: Changhuei Yang | First 5 Authors: Ruizhi Cao, Cheng Shen, Changhuei Yang, , | Summary: Computational imaging methods empower modern microscopy with the ability of producing high-resolution, large field-of-view, aberration-free images. One of the dominant computational label-free imaging methods, Fourier ptychographic microscopy (FPM), effectively increases the spatial-bandwidth product of conventional microscopy by using […]

Fermionic quantum computation with Cooper pair splitters

Posted by dbos Delft

Kavli Affiliate: Anton Akhmerov | First 5 Authors: Kostas Vilkelis, Antonio Manesco, Juan Daniel Torres Luna, Sebastian Miles, Michael Wimmer | Summary: We propose a practical implementation of a universal quantum computer that uses local fermionic modes (LFM) rather than qubits. Our design consists of quantum dots tunnel coupled by a hybrid superconducting island together […]
