Dynamical Freezing in Exactly Solvable Models of Driven Chaotic Quantum Dots

Posted by Cornell

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Haoyu Guo, Rohit Mukherjee, Debanjan Chowdhury, , | Summary: The late-time equilibrium behavior of generic interacting models is determined by the coupled hydrodynamic equations associated with the globally conserved quantities. In the presence of an external time-dependent drive, non-integrable systems typically thermalize to an effectively infinite-temperature state, […]

Excitation-Dependent Features and Artifacts in 2-D Terahertz Spectroscopy

Posted by Cornell

Kavli Affiliate: Ankit Disa | First 5 Authors: Albert Liu, Ankit Disa, , , | Summary: Recently, two-dimensional terahertz spectroscopy (2DTS) has attracted increasing attention for studying complex solids. A number of recent studies have applied 2DTS either with long pulses or away from any material resonances, situations that yield unconventional 2DTS spectra that are […]

Microscopic origin of twist-dependent electron transfer rate in bilayer graphene

Posted by dbos Berkeley

Kavli Affiliate: David T. Limmer | First 5 Authors: Leonardo Coello Escalante, David T. Limmer, , , | Summary: Using molecular simulation and continuum dielectric theory, we consider how electrochemical kinetics are modulated as a function of twist angle in bilayer graphene electrodes. By establishing an effective connection between twist angle and the screening length […]

Colloidal dispersions of sterically and electrostatically stabilized PbS quantum dots: the effect of stabilization mechanism on structure factors, second virial coefficients, and film-forming properties

Posted by dbos Berkeley

Kavli Affiliate: Naomi S. Ginsberg | First 5 Authors: Ahhyun Jeong, Josh Portner, Christian P. N. Tanner, Justin C. Ondry, Chenkun Zhou | Summary: Electrostatically stabilized nanocrystals (NCs) and, in particular, quantum dots (QDs) hold promise for forming strongly coupled superlattices due to their compact and electronically conductive surface ligands. However, studies on the colloidal […]
