Coherent advantage in the computational expressivity of excitonic networks
Matthew Du, Carlos Floyd, Dipti Jasrasaria +1
The rising energy consumption of AI has generated interest in physical systems as alternative substrates for trainable computation. Recent experimental advances have enabled precis…
Simulating anharmonic vibrational polaritons beyond the long wavelength approximation
Dipti Jasrasaria, Arkajit Mandal, David R. Reichman +1
In this work we investigate anharmonic vibrational polaritons formed due to strong light-matter interactions in an optical cavity between radiation modes and anharmonic vibrations…
Strong anharmonicity dictates ultralow thermal conductivities of type-I clathrates
Dipti Jasrasaria, Timothy C. Berkelbach
Type-I clathrate solids have attracted significant interest due to their ultralow thermal conductivities and subsequent promise for thermoelectric applications, yet the mechanisms…
Nonperturbative Simulation of Anharmonic Rattler Dynamics in Type-I Clathrates with Vibrational Dynamical Mean-Field Theory
Dipti Jasrasaria, Timothy C. Berkelbach
We use vibrational dynamical mean-field theory (VDMFT) to study the vibrational structure of type-I clathrate solids, specifically XGaGe, where X=Ba,Sr. These mat…
Detecting, distinguishing, and spatiotemporally tracking photogenerated charge and heat at the nanoscale
Hannah L. Weaver, Cora M. Went, Joeson Wong +4
Since dissipative processes are ubiquitous in semiconductors, characterizing how electronic and thermal energy transduce and transport at the nanoscale is vital for understanding a…
Circumventing the Phonon Bottleneck by Multiphonon-Mediated Hot Exciton Cooling at the Nanoscale
Dipti Jasrasaria, Eran Rabani
In semiconductor materials, hot exciton cooling is the process by which highly excited carriers nonradiatively relax to form a band edge exciton. While cooling plays an important r…
Theory of photoluminescence spectral line shapes of semiconductor nanocrystals
Kailai Lin, Dipti Jasrasaria, Jason J. Yoo +3
Single-molecule photoluminescence (PL) spectroscopy of semiconductor nanocrystals (NCs) reveals the nature of exciton-phonon interactions in NCs. Understanding the narrow line shap…
Simulating noise on a quantum processor: interactions between a qubit and resonant two-level system bath
Yujin Cho, Dipti Jasrasaria, Keith G. Ray +4
Material defects fundamentally limit the coherence times of superconducting qubits, and manufacturing completely defect-free devices is not yet possible. Therefore, understanding t…
Simulations of nonradiative processes in semiconductor nanocrystals
Dipti Jasrasaria, Daniel Weinberg, John P. Philbin +1
The description of carrier dynamics in spatially confined semiconductor nanocrystals (NCs), which have enhanced electron-hole and exciton-phonon interactions, is a great challenge…
Dynamic lattice distortions driven by surface trapping in semiconductor nanocrystals
Burak Guzelturk, Benjamin L. Cotts, Dipti Jasrasaria +26
Nonradiative processes limit optoelectronic functionality of nanocrystals and curb their device performance. Nevertheless, the dynamic structural origins of nonradiative relaxation…
Dynamic Control of Explore/Exploit Trade-Off In Bayesian Optimization
Dipti Jasrasaria, Edward O. Pyzer-Knapp
Bayesian optimization offers the possibility of optimizing black-box operations not accessible through traditional techniques. The success of Bayesian optimization methods such as…
Space-Filling Curves as a Novel Crystal Structure Representation for Machine Learning Models
Dipti Jasrasaria, Edward O. Pyzer-Knapp, Dmitrij Rappoport +1
A fundamental problem in applying machine learning techniques for chemical problems is to find suitable representations for molecular and crystal structures. While the structure re…
