Normal state of metal-intercalated phenacene crystals: Role of electron correlations
Tirthankar Dutta, Sumit Mazumdar
In this work we study the effect of long range electron-electron correlations on the behavior of the normal state of metal-intercalated phenacene crystals. While the individual phe…
Theory of Primary Photoexcitations in Donor-Acceptor Copolymers
Karan Aryanpour, Tirthankar Dutta, Uyen N. V. Huynh +2
We present a generic theory of primary photoexcitations in low band gap donor-acceptor conjugated copolymers. Because of the combined effects of strong electron correlations and br…
Coulomb Enhanced Superconducting Pair Correlations in the Frustrated Quarter-Filled Band
Niladri Gomes, W. Wasanthi De Silva, Tirthankar Dutta +2
A necessary condition for superconductivity (SC) driven by electron correlations is that electron-electron (e-e) interactions enhance superconducting pair-pair correlations, relati…
Theory of metal-intercalated phenacenes: Why molecular valence 3 is special
Tirthankar Dutta, Sumit Mazumdar
We develop a correlated-electron minimal model for the normal state of charged phenanthrene ions in the solid state, within the reduced space of the two lowest antibonding molecula…
Effect of dimerization on dynamics of spin-charge separation in Pariser-Parr-Pople model: A time-dependent density matrix renormalization group study
Tirthankar Dutta, S. Ramasesha
We investigate the effect of static electron-phonon coupling, on real-time dynamics of spin and charge transport in -conjugated polyene chains. The polyene chain is modeled by t…
Real-time density matrix renormalization group dynamics of spin and charge transport in push-pull polyenes and related systems
Tirthankar Dutta, S. Ramasesha
In this paper we investigate the effect of terminal substituents on the dynamics of spin and charge transport in donor-acceptor substituted polyenes () chains, also k…
Real Time Dynamics of Hole Propagation in Strongly Correlated Conjugated Molecular Chains: A time-dependent DMRG Study
Tirthankar Dutta, S. Ramasesha
In this paper, we address the role of electron-electron interactions on the velocities of spin and charge transport in one-dimensional systems typified by conjugated polymers. We e…
Double Time Window Targeting Technique: Real time DMRG dynamics in the PPP model
Tirthankar Dutta, S. Ramasesha
We present a generalized adaptive time-dependent density matrix renormalization group (DMRG) scheme, called the {\it double time window targeting} (DTWT) technique, which gives acc…
