Correlated-Electron Theory of Triplet-Triplet Multiexciton States in Polypentacene
Rupali Jindal, Alok Shukla, Sumit Mazumdar
We present correlated-electron calculations of optical spin-singlet and triplet-triplet multiexciton states in three- and four-unit pentacene oligomers as microscopic models for po…
Exciton Basis Description of Ultrafast Triplet Separation in Pentacene-(Tetracene)2-Pentacene Intramolecular Singlet Fission Chromophore
Arifa Nazir, Alok Shukla, Sumit Mazumdar
Precise understanding of the electronic structures of optically dark triplet-triplet multiexcitons that are the intermediate states in singlet fission (SF) continues to be a challe…
Comment on "Superconductivity and Mott Physics in Organic Charge Transfer Materials"
Rupali Jindal, Sumit Mazumdar, R. Torsten Clay
Menke et al. recently claimed that superconductivity (SC) in the -phase organic charge-transfer solids (CTS) can be understood within the two-dimensional half-filled anisotropic…
Computational Demonstrations of Density Wave of Cooper Pairs and Paired-Electron Liquid in the Quarter-Filled Band -- a Brief Review
Sumit Mazumdar, R. Torsten Clay
There has been strong interest recently in the so-called Cooper pair density wave, subsequent to the proposition that such a state occurs in the hole-doped cuprate superconductors.…
Absence of superconductivity in the Hubbard dimer model for kappa-(BEDT-TTF)_2X
D. Roy, R. T. Clay, S. Mazumdar
In the most studied family of organic superconductors kappa-(BEDT-TTF)_2X, the BEDT-TTF molecules that make up the conducting planes are coupled as dimers. For some anions X, an an…
Bond patterns and charge order amplitude in 1/4-filled charge-transfer solids
R. T. Clay, A. B. Ward, N. Gomes +1
Metal-insulator transition accompanied by charge-ordering has been widely investigated in quasi-one-dimensional conductors, including in particular organic charge-transfer solids.…
Ultrafast optical nonlinearity in quasi-one-dimensional Mott-insulator
T. Ogasawara, M. Ashida, N. Motoyama +7
We report strong instantaneous photoinduced absorption (PA) in the quasi-one-dimensional Mott insulator in the IR spectral region. The observed PA is to an even-p…
