Cluster Gutzwiller study of Bose-Hubbard ladder: ground-state phase diagram and many-body Landau-Zener dynamics
Haiming Deng, Hui Dai, Jiahao Huang +5
We present a cluster Gutzwiller mean-field study for ground states and time-evolution dynamics in the Bose-Hubbard ladder (BHL), which can be realized by loading Bose atoms in doub…
Current Eigenmodes and Dephasing in Nanoscopic Quantum Networks
Tankut Can, Hui Dai, Dirk K. Morr
Using the non-equilibrium Keldysh Green's function formalism, we show that the non-equilibrium charge transport in nanoscopic quantum networks takes place via {\it current eigenmod…
Nonlinear quantum interferometry with Bose condensed atoms
Chaohong Lee, Jiahao Huang, Haiming Deng +2
In quantum interferometry, it is vital to control and utilize nonlinear interactions for achieving high-precision measurements. Attribute to their long coherent time and high contr…
Non-equilibrium Transport in dissipative one-dimensional Nanostructures
Hui Dai, Dirk K. Morr
We study the non-equilibrium transport properties of a one-dimensional array of dissipative quantum dots. Using the Keldysh formalism, we show that the dots' dissipative nature lea…
Asymptotics of eigenvalues and eigenvectors of Toeplitz matrices
Hui Dai, Zachary Geary, Leo P. Kadanoff
A Toeplitz matrix is one in which the matrix elements are constant along diagonals. The Fisher-Hartwig matrices are much-studied singular matrices in the Toeplitz family. The matri…
Asymptotic eigenvalue distribution of large Toeplitz matrices
Seung-Yeop Lee, Hui Dai, Eldad Bettelheim
We study the asymptotic eigenvalue distribution of Toeplitz matrices generated by a singular symbol. It has been conjectured by Widom that, for a generic symbol, the eigenvalues co…
