Generating scalable graph states in an atom-nanophotonic interface
C. -H. Chien, S. Goswami, C. -C. Wu +3
Scalable graph states are essential for measurement-based quantum computation and many entanglement-assisted applications in quantum technologies. Generation of these multipartite…
Atomic excitation delocalization at the clean to disordered interface in a chirally-coupled atomic array
C. -C. Wu, K. -T. Lin, I G. N. Y. Handayana +5
In one-dimensional quantum emitter systems, the dynamics of atomic excitations are influenced by the collective coupling between emitters through photon-mediated dipole-dipole inte…
Plaquette valence bond state in spin-1/2 J1-J2 XY model on square lattice
Y. -H. Chan, Hong-Chen Jiang, Y. -C. Chen
We studied the ground state phase diagram of spin-1/2 J1-J2 XY model on the square lattice with first- J1 and second-neighbor J2 antiferromagnetic interactions using both iDMRG and…
Resonant Dipole-Dipole Interactions in Electromagnetically Induced Transparency
H. H. Jen, G. -D. Lin, Y. -C. Chen
Resonant dipole-dipole interaction (RDDI) is ubiquitous in light-matter interacting systems and is responsible for many fascinating properties of collective radiations. Here we the…
Quarter-filled supersolid and solid phases in the extended Bose-Hubbard model
Kwai-Kong Ng, Y. C. Chen, Y. C. Tzeng
We numerically study the ground state phase diagram of the two-dimensional hard-core Bose-Hubbard model with nearest () and next nearest neighbor () repulsions. In partic…
Enhancement of Pairing Correlation by t' in the Two-Dimensional Extende d t-J Model
C. T. Shih, T. K. Lee, R. Eder +2
We investigate the effects of the next-nearest-neighbor () and the third-nearest-neighbor (t") hopping terms on superconductivity (SC) correlation in the 2D hole-doped extended…
Revisit Phase Separation of the Two-Dimensional model by the Power-Lanczos Method
C. T. Shih, Y. C. Chen, T. K. Lee
The power-Lanczos (PL) method is one kind of Green's function Monte-Carlo simulation, which is improved by Lanczos iterations. The ground state energies of strongly-correlated mode…
Long-range order and low-energy spectrum of diluted 2D quantum AF
A. L. Chernyshev, Y. C. Chen, A. H. Castro Neto
The problem of diluted two-dimensional (2D) quantum antiferromagnet (AF) on a square lattice is studied using spin-wave theory. The influence of impurities on static and dynamic pr…
Phase Separation of the Two-Dimensional t-J model
C. T. Shih, Y. C. Chen, T. K. Lee
The boundary of phase separation of the two-dimensional t-J model is investigated by the power-Lanczos method and Maxwell construction. The method is similar to a variational appro…
Variational Study of the Spin-Gap Phase of the One-Dimensional t-J Model
Y. C. Chen, T. K. Lee
We propose a correlated spin-singlet-pairs wave function to describe the spin-gap phase of the one-dimensional model at low density. Adding a Jastrow factor with a variationa…
Superconductivity Near Phase Separation in Models of Correlated Electrons
E. Dagotto, J. Riera, Y. C. Chen +4
Numerical and analytical studies of several models of correlated electrons are discussed. Based on exact diagonalization and variational Monte Carlo techniques, we have found stron…
