Third harmonic generation enhancement and wavefront control using a local high-Q metasurface

Posted by klaurent Caltech

Kavli Affiliate: Harry Atwater | Summary:High quality factor optical nanostructures provide great opportunity to enhance nonlinear optical processes such as third harmonic generation. However, the field enhancement in these high quality factor structures is typically accompanied by optical mode nonlocality. As a result, the enhancement of nonlinear processes comes at the cost of their local […]

Gene expression in growing cells: A biophysical primer

Posted by dbos Harvard

Kavli Affiliate: Ariel Amir | First 5 Authors: Ido Golding, Ariel Amir, , , | Summary: Cell growth and gene expression, essential elements of all living systems, have long been the focus of biophysical interrogation. Advances in single-cell methods have invigorated theoretical studies into these processes. However, until recently, there was little dialog between the […]

Magnetic field as a dynamic energy scale in quantum-critical CeCoIn$_5$

Posted by klaurent Cornell

Kavli Affiliate: Brad Ramshaw | Summary:Whether magnetic field enters the quantum-critical dynamics as a competing energy scale in strange metals remains an open question. Using thermal impedance spectroscopy, we simultaneously measure the electronic specific heat and spin-relaxation dynamics of CeCoIn$_5$. Both properties show scale invariance with temperature and magnetic field, where a single energy scale […]

Magnetic field-temperature competition and quantum criticality in a strange metal

Posted by klaurent Cornell

Kavli Affiliate: Brad Ramshaw | Summary:Strange metals defy the quasiparticle description of conventional metals, exhibiting a linear in temperature ($T$-linear) resistivity in a broad temperature range. It has become increasingly clear that, together with $T$-linear resistivity, strange metals exhibit a characteristic response in strong magnetic fields, which might point to the quantum critical origin of […]

Transitive and non-transitive subgroups of permutation groups

Posted by dbos UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Arda Demirhan, Jacob Miller, Yixu Qiu, Thomas J. Tucker, Zheng Zhu | Summary: We treat the problem of finding transitive subgroups G of S_n containing normal subgroups N_1 and N_2, with N_1 transitive and N_2 not transitive, such that G/N_1 is isomorphic G/N_2. We show that such […]
