Inferring simple but precise quantitative models of human oocyte and early embryo development

Posted by dbos Harvard

Kavli Affiliate: Daniel Needleman | First 5 Authors: Brian D Leahy, Catherine Racowsky, Daniel Needleman, , | Summary: Macroscopic, phenomenological models have proven useful as concise framings of our understandings in fields from statistical physics to economics to biology. Constructing a phenomenological model for development would provide a framework for understanding the complicated, regulatory nature […]

Random-access quantum memory using chirped pulse phase encoding

Posted by klaurent Berkeley

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: James O’Sullivan, Oscar W. Kennedy, Kamanasish Debnath, Joseph Alexander, Christoph W. Zollitsch | Summary: As in conventional computing, key attributes of quantum memories are high storage density and, crucially, random access, or the ability to read from or write to an arbitrarily chosen register. However, achieving such […]

Self-regulating soliton domain walls in microresonators

Posted by klaurent Caltech

Kavli Affiliate: Kerry Vahala | First 5 Authors: Heming Wang, Boqiang Shen, Yan Yu, Zhiquan Yuan, Chengying Bao | Summary: Dissipative soliton Kerr frequency combs in microresonators have recently been demonstrated with the self-injection locking process. They have the advantage of turnkey deterministic comb generation and simplifying dark soliton generation in the normal dispersion regime. […]

Non-universal current flow near the metal-insulator transition in an oxide interface

Posted by klaurent Delft

Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Eylon Persky, Naor Vardi, Ana Mafalda R. V. L. Monteiro, Thierry C. van Thiel, Hyeok Yoon | Summary: In systems near phase transitions, macroscopic properties often follow algebraic scaling laws, determined by the dimensionality and the underlying symmetries of the system. The emergence of such universal […]

Accurate Measurement of the Gap of Graphene/hBN Moiré Superlattice through Photocurrent Spectroscopy

Posted by dbos Cornell

Kavli Affiliate: Paul L. McEuen | First 5 Authors: Tianyi Han, Jixiang Yang, Qihang Zhang, Lei Wang, Kenji Watanabe | Summary: Monolayer graphene aligned with hexagonal boron nitride (hBN) develops a gap at the charge neutrality point (CNP). This gap has previously been extensively studied by electrical transport through thermal activation measurements. Here, we report […]
