Signatures of Bloch-band geometry on excitons: non-hydrogenic spectra in\n transition metal dichalcogenides

Ajit M. Srivastava、Ataç İmamoğlu2015-07-14arXiv (Cornell University)

The geometry of electronic bands in a solid can drastically alter\nsingle-particle charge and spin transport. We show here that collective optical\nexcitations arising from Coulomb interactions also exhibit unique signatures of\nBerry curvature and quantum geometric tensor. A non-zero Berry curvature mixes\nand lifts…

Optical evidence of broken C$_4$ symmetry across optimal doping in BaFe$_{2}$(As$_{1-x}$P$_x$)$_2$

Eric Thewalt、James P. Hinton、Ian Hayes 等 7 位作者2015-07-14arXiv (Cornell University)

The isovalently doped high-$T_{\text{c}}$ superconductor BaFe$_2$(As$_{1-x}$P$_x$)$_2$ is characterized by a rich temperature-doping phase diagram, which includes structural, antiferromagnetic, and superconducting phase transitions. In this work, we use photomodulated reflectance at 1.5 eV to detect the onset of linea…

Protein-Ligand Binding Potential of Mean Force Calculations with Hamiltonian Replica Exchange on Alchemical Interaction Grids

David D. L. Minh2015-07-14arXiv (Cornell University)

A binding potential of mean force (BPMF) is a free energy of noncovalent association in which one binding partner is flexible and the other is rigid. I have developed a method to calculate BPMFs for protein-ligand systems. The method is based on replica exchange sampling from multiple thermodynamic states at different…
