Exciton-Trion-Polaritons in Two-Dimensional Materials

Kavli Affiliate: Farhan Rana | First 5 Authors: Farhan Rana, Okan Koksal, Minwoo Jung, Gennady Shvets, A. Nick Vamivakas | Summary: We present a many-body theory for exciton-trion-polaritons in doped two-dimensional materials. Exciton-trion-polaritons are robust coherent hybrid excitations involving excitons, trions, and photons. Signatures of these polaritons have been recently seen in experiments. In these […]

Many-body theory of radiative lifetimes of exciton-trion superposition states in doped two-dimensional materials

Kavli Affiliate: Farhan Rana | First 5 Authors: Farhan Rana, Okan Koksal, Minwoo Jung, Gennady Shvets, Christina Manolatou | Summary: Optical absorption and emission spectra of doped two-dimensional (2D) materials exhibit sharp peaks that are often identified with pure excitons and pure trions (or charged excitons), but both peaks have been recently attributed to superpositions […]

Strain game revisited for complex oxide thin-films: Substrate-film thermal expansion mismatch in PbTiO$_3$

Kavli Affiliate: Nicole A. Benedek | First 5 Authors: Ethan T. Ritz, Nicole A. Benedek, , , | Summary: The sensitivity of materials properties, particularly those of perovskite oxides, to epitaxial strain has been exploited to great advantage to create materials with new or enhanced properties. Although it has certainly been recognized that mismatch in […]

Small-area Population Forecast in a Segregated City using Density-Functional Fluctuation Theory

Kavli Affiliate: Itai Cohen | First 5 Authors: Yuchao Chen, Yunus A. Kinkhabwala, Boris Barron, Matthew Hall, Tomas A. Arias | Summary: Decisions regarding housing, transportation, and resource allocation would all benefit from accurate small-area population forecasts. While various tried-and-tested forecast methods exist at regional scales, developing an accurate neighborhood-scale forecast remains a challenge partly […]

An Ising Hamiltonian Solver using Stochastic Phase-Transition Nano- Oscillators

Kavli Affiliate: Darrell Schlom | First 5 Authors: Sourav Dutta, Abhishek Khanna, Adou S. Assoa, Hanjong Paik, Darrell Schlom | Summary: Computationally hard problems, including combinatorial optimization, can be mapped into the problem of finding the ground-state of an Ising Hamiltonian. Building physical systems with collective computational ability and distributed parallel processing capability can accelerate […]

Bidirectional Self-Folding with Atomic Layer Deposition Nanofilms for Microscale Origami

Kavli Affiliate: Paul L. McEuen | First 5 Authors: Baris Bircan, Marc Z. Miskin, Robert J. Lang, Michael C. Cao, Kyle J. Dorsey | Summary: Origami design principles are scale invariant and enable direct miniaturization of origami structures provided the sheets used for folding have equal thickness to length ratios. Recently, seminal steps have been […]

Spectral and spatial isolation of single WSe$_2$ quantum emitters using hexagonal boron nitride wrinkles

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: RaphaĆ«l S. Daveau, Tom Vandekerckhove, Arunabh Mukherjee, Zefang Wang, Jie Shan | Summary: Monolayer WSe$_2$ hosts bright single-photon emitters. Because of its compliance, monolayer WSe$_2$ conforms to patterned substrates without breaking, thus creating the potential for large local strain, which is one activation mechanism of its […]

Fingerprints of the Strong Interaction between Monolayer MoS2 and Gold

Kavli Affiliate: Hector D. Abruna | First 5 Authors: Matej Velicky, Alvaro Rodriguez, Milan Bousa, Andrey V. Krayev, Martin Vondracek | Summary: Gold-mediated exfoliation of MoS2 has attracted considerable interest in the recent years. A strong interaction between MoS2 and Au facilitates preferential production of centimeter-sized monolayer MoS2 with near-unity yield and provides a heterostructure […]
