Coalescence of limit cycles in the presence of noise
Sergei Shmakov, Peter B. Littlewood
Complex dynamical systems may exhibit multiple steady states, including time-periodic limit cycles, where the final trajectory depends on initial conditions. With tuning of paramet…
Going Beyond the Cumulant Approximation II:Power Series Correction to Single Particle Green's Function in 1D Holstein Chain
Bipul Pandey, Peter B. Littlewood
Previously, we introduced a method for systematically correcting a quasiparticle green's function via a power series expansion. Here we present an ODE based formalisms of power ser…
Anharmonic multiphonon origin of the valence plasmon in SrTi1-xNbxO3
Caitlin S. Kengle, Samantha I. Rubeck, Melinda Rak +10
Doped SrTi1-xNbxO3 exhibits superconductivity and a mid-infrared optical response reminiscent of copper-oxide superconductors. Strangely, its plasma frequency, omega_p, increases b…
Exceptional points in nonlinear and stochastic dynamics
Cheyne Weis, Michel Fruchart, Ryo Hanai +3
We study a class of bifurcations generically occurring in dynamical systems with non-mutual couplings ranging from models of coupled neurons to predator-prey systems and non-linear…
Quantum Melting in a Polariton Lattice
Alexander Edelman, Peter B. Littlewood
Inspired by the recent experimental observation of strongly coupled polaritons in a Moiré heterobilayer, we study a model of dipole-interacting excitons localized on sites of a lat…
Semi-metallicity and electron-hole liquid in two-dimensional C and BN based compounds
Alejandro Lopez-Bezanilla, Peter B. Littlewood
Insulating-metallic transition mediated by substitutional atoms is predicted in a series of two-dimensional carbon-based structures. Introducing Si atoms in selected sites of tetra…
