(Sub)nanoscale Visualization of Reconstruction-Driven Moiré Exciton Localization and Delocalization
Medha Dandu, Sriram Sankar, Giovanny Espitia +12
Spectral fingerprints in optical absorption and emission have typically been used as a signature of exciton localization in twisted moiré bilayers. However, the mechanism by which…
Topology and compact molecular orbitals in twisted bilayer WSe
Chenyuan Li, Rwik Dutta, Fang Xie +4
Recent observations of superconductivity in twisted bilayer WSe (tWSe) have motivated theoretical proposals for unconventional pairing mechanisms. A central question is whe…
Tunable Interlayer Charge-transfer States in MoSe/WS Moiré Superlattices
Zheyu Lu, Jiahui Nie, Tianle Wang +15
Moiré superlattices formed by transition metal dichalcogenide (TMD) heterobilayers provide a versatile platform for studying strongly correlated electronic, excitonic, and topologi…
Signatures of moiré intralayer biexcitons and exciton-phason coupling in WSe2/WS2 heterostructures
Ranju Dalal, Harsimran Singh, Rwik Dutta +6
Interactions among electronic and lattice degrees-of-freedom are foundational to various phases in condensed-matter physics, yet the dynamic interplay between excitonic and phononi…
Imaging Electron-Hole Asymmetry in the Quantum Melting of Generalized Wigner Crystals
Emma Berger, Michael Arumainayagam, Zhihuan Dong +12
Two-dimensional moiré materials provide a versatile platform to explore phase transitions in strongly correlated systems. Using scanning tunneling microscopy (STM) we have imaged t…
Bengali Handwritten Character Classification using Transfer Learning on Deep Convolutional Neural Network
Swagato Chatterjee, Rwik Kumar Dutta, Debayan Ganguly +2
In this paper, we propose a solution which uses state-of-the-art techniques in Deep Learning to tackle the problem of Bengali Handwritten Character Recognition ( HCR ). Our method…
