Truncation effects in the charge representation of the O(2) model
Jin Zhang, Yannick Meurice, Shan-Wen Tsai
The O(2) model in Euclidean space-time is the zero-gauge-coupling limit of the compact scalar quantum electrodynamics. We obtain a dual representation of it called the charge repre…
Effect of mediated interactions on a Hubbard chain in mixed-dimensional fermionic cold atoms
Junichi Okamoto, Wen-Min Huang, Kyle Irwin +2
Cold atom experiments can now realize mixtures where different components move in different spatial dimensions. We investigate a fermion mixture where one species is constrained to…
Quantum Joule Expansion of One-Dimensional Systems
Jin Zhang, Y. Meurice, S. -W. Tsai
We investigate the Joule expansion of nonintegrable quantum systems that contain bosons or spinless fermions in one-dimensional lattices. A barrier initially confines the particles…
Weak three-dimensional mediators of two-dimensional triplet pairing
Shane Kelly, S. -W. Tsai
Recent experiments demonstrate the ability to construct cold atom mixtures with species selective optical lattices. This allows for the possibility of a mixed-dimension system, whe…
d_{xy}-Density wave in fermion-fermion cold atom mixtures
Chen-Yen Lai, Wen-Min Huang, David K. Campbell +1
We study density wave instabilities in a doubly-degenerate Fermi-Fermi mixture with symmetry on a square lattice. For sufficiently large on-site inter-species r…
Possible quantum phase-manipulation of a two-leg ladder in mixed-dimensional fermionic cold atoms
Wen-Min Huang, Kyle Irwin, Shan-Wen Tsai
The recent realization of mixed-dimensional systems of cold atoms has attracted much attention from both experimentalists and theorists. Different effective interactions and novel…
