  • Nuclear level lifetime measurements across varied ranges using the digital INGA at TIFR

    Rudrajyoti Palit & Rajarshi Raut

    Abstract This article highlights the significance of level lifetime measurements in nuclear structure studies that principally center on probing the myriad excitation phenomena exhibited by nuclei through evolving regimes of excitations in energy, angular momentum, and isospin. The same has been illustrated through discussions on some of the measurements undertaken using the Indian National Gamma Array (INGA) set up at the BARC-TIFR Pelletron LINAC Facility (PLF) in TIFR, Mumbai. The diverse ph

  • Neutron emission spectrometer in magnetic confinement fusion

    Siriyaporn Sangaroon, Kunihiro Ogawa & Mitsutaka Isobe

    Abstract Comprehensive neutron diagnostics have been developed and used to study magnetic confinement fusion plasmas. The neutron emission spectrometer is one of the most powerful tools for understanding fusion plasma physics. Neutron spectroscopy was originally developed to measure the fuel ion temperature in thermal plasmas. With the advent of fast ion heating, the role of neutron spectroscopy has evolved to deepen the understanding of fast ion confinement. Since neutrons are primarily produc

  • Fundamental understanding of voltage decay in Li-rich Mn-based layered oxides cathode materials

    Huixian Xie, Jiacheng Xiao, Hongyi Chen, Boyang Zhang, Kwun Nam Hui, Shanqing Zhang, Chenyu Liu, Dong Luo & Zhan Lin

    Abstract To satisfy the needs of modern intelligent society for power supplies with long-endurance ability, Li-rich Mn-based layered oxides (LRMOs) are receiving much attention because of their ultrahigh capacity. However, their real-world implementation is hindered by the serious voltage decay, which results in a continuous decrease in energy density. The understanding on voltage decay still remains a mystery due to the complicated hybrid cationic-anionic redox and the serious surface-interfac

  • Wavelength multicasting quantum clock synchronization network

    Jiaao Li, Hui Han, Xiaopeng Huang, Bangying Tang, Kai Guo, Jinquan Huang, Siyu Xiong, Wanrong Yu, Zhaojian Zhang, Junbo Yang, Bo Liu, Huan Chen & Zhenkun Lu

    Abstract Quantum clock synchronization (QCS) can measure out the high-precision clock difference among distant users, which breaks through the standard quantum limit by employing the properties of quantum entanglement. Currently, the wavelength division multiplexed QCS network has been demonstrated with a spontaneous parametric down-conversion entangled photon source. In this paper, we propose a more efficient QCS network scheme with the wavelength multicasting entangled photon source, which ca

  • Non-equilibrium BCS-BEC crossover and unconventional FFLO superfluid in a strongly interacting driven-dissipative Fermi gas

    Taira Kawamura & Yoji Ohashi

    Abstract We present a theoretical review of the recent progress in non-equilibrium BCS (Bardeen-Cooper-Schrieffer)-BEC (Bose-Einstein condensation) crossover physics. As a paradigmatic example, we consider a strongly interacting driven-dissipative two-component Fermi gas where the non-equilibrium steady state is tuned by adjusting the chemical potential difference between two reservoirs that are coupled with the system. As a powerful theoretical tool to deal with this system, we employ the Schw

    2 The three “meetings” of life—recalling Mr. Guangzhao by Enge Wang On the evening of August 17, 2024, while I was still on my way to visit abroad, I suddenly received the news that Mr. Guangzhao had passed away. For a moment, I was choked up and did not know what to say. Slowly, the scenes of my interactions with Mr. Guangzhao over the past decades began to emerge. For the Chinese scientific community, Mr. Guangzhao’s departure is a great loss in every dimension. For those of us who were born
