Odd Diffusion in Three-Dimensional Isotropic Media
Viola Zixin Zhao, Andres Franco Valiente, David T. Limmer
Odd diffusion is a hallmark of chiral active matter, generating currents transverse to density gradients. Existing theories rely on a linear antisymmetric transport coefficient tha…
Origins of suppressed self-diffusion of nanoscale constituents of a complex liquid
Christian P. N. Tanner, Vivian R. K. Wall, Mumtaz Gababa +25
Understanding and ultimately controlling the transformations and properties of nanoscale systems, from proteins to synthetic nanomaterial assemblies, is limited by the inability to…
Solvent Effects on Triplet Yields in BODIPY-Based Photosensitizers
Leonardo Coello Escalante, Thomas P. Fay, David T. Limmer
We employ molecular dynamics simulations and quantum rate theories to elucidate the complex condensed-phase dynamics underpinning triplet-state formation in organic photosensitizer…
Optimal control of bit erasure in stochastic random access memory
Songela W. Chen, David T. Limmer
Energy costs of information processing are growing exponentially. Bit erasure is a key problem in this energy-information nexus, and a number of seminal relationships have been ded…
Visualizing Millisecond Atomic Dynamics of Nanocrystals in Liquid
Sungsu Kang, Jinho Rhee, Joodeok Kim +11
Atomic structures of nanomaterials are inherently dynamic, continuously reshaped through interactions with chemical species and external stimuli. Such dynamics are further amplifie…
Influence Functional Approach to Non-Perturbative Exciton Binding Renormalization from Phonons
Rohit Rana, Eric R. Heller, Antonios M. Alvertis +2
We construct a many-body model Hamiltonian to capture how phonons renormalize exciton binding as a function of temperature. By using the GW approximation and density functional per…
