Competing correlated states around the zero field Wigner crystallization transition of electrons in two-dimensions

Posted by Caltech

Kavli Affiliate: Joseph Falson | First 5 Authors: Joseph Falson, Inti Sodemann, Brian Skinner, Daniela Tabrea, Yusuke Kozuka | Summary: The competition between kinetic energy and Coulomb interactions in electronic systems can lead to complex many-body ground states with competing superconducting, charge density wave, and magnetic orders. Here we study the low temperature phases of […]

Direct visualization of superselective colloid-surface binding mediated by multivalent interactions

Posted by dbos Delft

Kavli Affiliate: Liedewij Laan | First 5 Authors: Christine Linne, Daniele Visco, Stefano Angioletti-Uberti, Liedewij Laan, Daniela J. Kraft | Summary: Reliably distinguishing between cells based on minute differences in receptor density is crucial for cell-cell or virus-cell recognition, the initiation of signal transduction and selective targeting in directed drug delivery. Such sharp differentiation between […]

Understanding mechanisms of thermal expansion in PbTiO$_3$ thin-films from first principles: role of high-order phonon-strain anharmonicity

Posted by klaurent Cornell

Kavli Affiliate: Nicole A. Benedek | First 5 Authors: Ethan T. Ritz, Nicole A. Benedek, , , | Summary: The thermal properties of materials are critically important to various technologies and are increasingly the target of materials design efforts. However, it is only relatively recent advances in first-principles computational techniques that have enabled researchers to […]

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. […]
