Improving cosmological reach of a gravitational wave observatory using Deep Loop Shaping

Posted by klaurent Caltech, This Week: Nanoscience

Kavli Affiliate: Rana X. Adhikari | First 5 Authors: , , , , | Summary: Improved low-frequency sensitivity of gravitational wave observatories would unlock study of intermediate-mass black hole mergers, binary black hole eccentricity, and provide early warnings for multi-messenger observations of binary neutron star mergers. Today’s mirror stabilization control injects harmful noise, constituting a […]

Separating the control of moving and holding still in post-stroke arm paresis

Posted by klaurent Hopkins, This Week: Neuroscience

Kavli Affiliate: Reza Shadmehr | Authors: Alkis M. Hadjiosif, Kahori Kita, Scott T. Albert, Robert A. Scheidt, Reza Shadmehr and John W. Krakauer | Summary: Moving and holding still have been posited to be under separate control regimes for both eye and arm movements. The paretic arm after stroke is notable for abnormalities both at […]

10-W Sub-100-fs Ultrafast Cr:ZnS/ZnSe MOPA System enabled by doping gradient engineering

Posted by klaurent This Week: Theoretical Physics, UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: Guangzi Feng, Guangzi Feng, , , | Summary: We report on a high-power mid-infrared femtosecond master oscillator power amplifier (MOPA) system, employing Cr:ZnS and Cr:ZnSe polycrystals with fine-tuned doping profiles. Based on the soft-aperture Kerr-lens mode-locking in the soliton regime, the seed oscillator generates ~40-fs pulses with […]

Aeos is Mixing it Up: The (In)homogeneity of Metal Mixing Following Population III Star Formation

Posted by klaurent MIT, This Week: Astrophysics

Kavli Affiliate: Anna Frebel | First 5 Authors: Jennifer Mead, Jennifer Mead, , , | Summary: Stellar surface abundances are records of the state of the gas from which stars formed, and thus trace how individual elements have mixed into the surrounding medium following their ejection from stars. In this work, we test the common […]

Thermal states emerging from low-entanglement background in disordered spin models

Posted by klaurent This Week: Theoretical Physics, UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Yule Ma, Yule Ma, , , | Summary: Thermalization in isolated quantum systems is governed by the eigenstate thermalization hypothesis, while strong disorder can induce its breakdown via many-body localization. Here we show that disorder can also generate a narrow band of thermal eigenstates embedded in an […]
