Kavli Affiliate: Michael Wimmer | 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. The device layout consists of quantum dots tunnel coupled by a hybrid superconducting island […]
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 […]
Kavli Affiliate: Jia Liu | First 5 Authors: Mingxuan Du, Jia Liu, Xiao-Ping Wang, Tianhao Wu, | Summary: We investigate the enhancement of dark sector particle production within the scattering dominant regime. These particles typically exhibit a slight mixing with Standard Model particles through various portals, allowing for their generation through in-medium oscillation from Standard […]
Kavli Affiliate: Giordano Scappucci | First 5 Authors: Kenta Takeda, Akito Noiri, Takashi Nakajima, Leon C. Camenzind, Takashi Kobayashi | Summary: Silicon-based spin qubits offer a potential pathway toward realizing a scalable quantum computer owing to their compatibility with semiconductor manufacturing technologies. Recent experiments in this system have demonstrated crucial technologies, including high-fidelity quantum gates […]
Kavli Affiliate: Jeffrey Moses | First 5 Authors: Jiaoyang Zheng, Guru Khalsa, Jeffrey Moses, , | Summary: We observe strongly anisotropic third-harmonic generation mediated by resonant sum-frequency driving of Raman phonons with THz light, extending light-induced dual control of structural and optical properties in solids. Either strong enhancement or strong suppression of the third harmonic […]
Kavli Affiliate: Jeffrey Moses | First 5 Authors: Jiaoyang Zheng, Guru Khalsa, Jeffrey Moses, , | Summary: We demonstrate a strong, elastic, frequency-upshifting optical polarizability that accompanies sum-frequency driving of Raman phonons and two-photon absorption, extending the duality of structural and optical property modification recently observed in light-driven phononics. The effect, phonon-dressed third-harmonic generation (THG), […]
Kavli Affiliate: Yingjie Peng | First 5 Authors: , , , , | Summary: In this paper we investigate the role of AGN feedback on the late stage evolution of elliptical galaxies by performing high-resolution hydrodynamical simulation in the {it MACER} framework. By comparing models that take into account different feedback mechanisms, namely AGN and […]
Kavli Affiliate: Scott K. Cushing | First 5 Authors: Levi D. Palmer, Wonseok Lee, Chung Li Dong, Ru-Shi Liu, Nianqiang Wu | Summary: Most photocatalytic and photovoltaic devices operate under broadband, constant illumination. Electron and hole dynamics in these devices, however, are usually measured using ultrafast pulsed lasers in a narrow wavelength range. In this […]
Kavli Affiliate: Alex Zettl | First 5 Authors: Colum M. O’Leary, Haozhi Sha, Jianhua Zhang, Cong Su, Salman Kahn | Summary: We report three-dimensional (3D) structure determination of a twisted hexagonal boron nitride (h-BN) heterointerface from a single-view data set using multislice ptychography. We identify the buried heterointerface between two twisted h-BN flakes with a […]
Kavli Affiliate: Jing Wang | First 5 Authors: Yadong Jiang, Huan Wang, Kejie Bao, Jing Wang, | Summary: Intrinsic magnetic topological insulators offers an ideal platform to explore exotic topological phenomena, such as axion electrodynamics, quantum anomalous Hall (QAH) effect and Majorana edge modes. However, these emerging new physical effects have rarely been experimentally observed […]
