Optical Conductivity of the two dimensional Hubbard model: vertex corrections, emergent Galilean invariance and the accuracy of the single-site dynamical mean field approximation
Anqi Mu, Zhiyuan Sun, Andrew J. Millis
We compute the frequency dependent conductivity of the two dimensional square lattice Hubbard model at zero temperature as a function of density to second order in the interaction…
Spacial inhomogeneity and nonlinear tunneling for the forced KdV equation
Xin Yu, Zhi-Yuan Sun, Kai-Wen Zhou +1
A variable-coefficient forced Korteweg-de Vries equation with spacial inhomogeneity is investigated in this paper. Under constraints, this equation is transformed into its bilinear…
Performing Hong-Ou-Mandel-type Numerical Experiments with Repulsive Condensates: The case of Dark and Dark-bright Solitons
Zhi-Yuan Sun, Panayotis G. Kevrekidis, Peter Krüger
The Hong-Ou-Mandel experiment leads indistinguishable photons simultaneously reaching a 50:50 beam splitter to emerge on the same port through two-photon interference. Motivated by…
Soliton Mobility in Disordered Lattice
Zhi-Yuan Sun, Shmuel Fishman, Avy Soffer
We investigate soliton mobility in the disordered Ablowitz-Ladik (AL) model and the standard nonlinear Schrödinger (NLS) lattice with the help of an effective potential generalizin…
Soliton Trapping in Disordered Lattice
Zhi-Yuan Sun, Shmuel Fishman, Avy Soffer
Dynamics of solitons of the Ablowitz-Ladik model in the presence of a random potential is studied. In absence of the random potential it is an integrable model and the solitons are…
A Mean-Field Analogue of the Hong-Ou-Mandel Experiment With Bright Solitons
Zhi-Yuan Sun, Panayotis G. Kevrekidis, Peter Krüger
In the present work, we theoretically propose and numerically illustrate a mean-field analogue of the Hong-Ou-Mandel experiment with bright solitons. More specifically, we scatter…
