The interstellar medium of high-redshift galaxies: Gathering clues from C III] and [C II] lines

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Vladan Markov, Stefano Carniani, Livia Vallini, Andrea Ferrara, Andrea Pallottini | Summary: A tight relation between [C II] line luminosity and the star formation rate (SFR) has been observed for local galaxies. At high redshift (z > 5), galaxies instead deviate downwards from the local $Sigma$_[C II] […]

Enhanced superconductivity by near-neighbor attraction in the doped Hubbard model

Posted by klaurent UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Yao Wang, Jiajia Wen, Young Lee, Thomas Devereaux | Summary: Recent experiment has unveiled an anomalously strong electron-electron attraction in one-dimensional copper-oxide chain Ba$_{2-x}$Sr$_x$CuO$_{3+delta}$. While the near-neighbor electron attraction $V$ in the one-dimensional extended Hubbard chain has been examined recently, its effect in the Hubbard […]

Towards Understanding and Mitigating Audio Adversarial Examples for Speaker Recognition

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Guangke Chen, Zhe Zhao, Fu Song, Sen Chen, Lingling Fan | Summary: Speaker recognition systems (SRSs) have recently been shown to be vulnerable to adversarial attacks, raising significant security concerns. In this work, we systematically investigate transformation and adversarial training based defenses for securing SRSs. According to […]

Effects of Laser-Annealing on Fixed-Frequency Superconducting Qubits

Posted by klaurent Berkeley

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Hyunseong Kim, Christian Jünger, Alexis Morvan, Edward S. Barnard, William P. Livingston | Summary: As superconducting quantum processors increase in complexity, techniques to overcome constraints on frequency crowding are needed. The recently developed method of laser-annealing provides an effective post-fabrication method to adjust the frequency of superconducting […]
