Nonlinear Localized States on a Pyrochlore Lattice
Faustino Palmero Ramos, Avadh Saxena, Panayotis G. Kevrekidis
In the present work we explore a prototypical three-dimensional (3d) lattice possessing a flat band in the form of a pyrochlore lattice in the context of a dispersive nonlinear dyn…

Bayesian post-correction of non-Markovian errors in bosonic lattice gravimetry
Bharath Hebbe Madhusudhana, Andrew Harter, Avadh Saxena
We study gravimetry with bosonic trapped atoms in the presence of random spatial inhomogeneity. The errors resulting from a random, shot-to-shot fluctuating spatial inhomogeneity a…

Quantum Dynamics with Stochastic Non-Hermitian Hamiltonians
Pablo Martinez-Azcona, Aritra Kundu, Avadh Saxena +2
We study the quantum dynamics generated by a non-Hermitian Hamiltonian subject to stochastic perturbations in its anti-Hermitian part, describing fluctuating gains and losses. The…
