THz-Frequency Modulation of the Hubbard U in an Organic Mott Insulator
R. Singla, G. Cotugno, S. Kaiser +10
We use midinfrared pulses with stable carrier-envelope phase offset to drive molecular vibrations in the charge transfer salt ET-F2TCNQ, a prototypical one-dimensional Mott insulat…
Pressure dependent relaxation in the photo-excited Mott insulator ETF2TCNQ: Influence of hopping and correlations on quasiparticle recombination rates
M. Mitrano, G. Cotugno, S. R. Clark +12
Femtosecond relaxation of photo-excited quasiparticles in the one dimensional Mott insulator ET-F2TCNQ are measured as a function of external pressure, which is used to tune the el…
Ab initio derivation of Hubbard models for cold atoms in optical lattices
R. Walters, G. Cotugno, T. H. Johnson +2
We derive ab initio local Hubbard models for several optical lattice potentials of current interest, including the honeycomb and Kagomé lattices, verifying their accuracy on each o…
Deconstructing the Hubbard Hamiltonian by Ultrafast Quantum Modulation Spectroscopy in Solid-state Mott Insulators
S. Kaiser, S. R. Clark, D. Nicoletti +8
Most available theories for correlated electron transport are based on the Hubbard Hamiltonian. In this effective theory, renormalized hopping and interaction parameters only impli…
Charmed Baryonium
G Cotugno, R Faccini, AD Polosa +1
We re-analyze the published data on the Y(4630) --> Lambda_c Lambdabar_c and the Y(4660) --> psi(2S) pi pi with a consistent Ansatz and we find that the two observations are likely…
