Time-dependent correlation function of the Jordan-Wigner operator as a Fredholm determinant
M. B. Zvonarev, V. V. Cheianov, T. Giamarchi
We calculate a correlation function of the Jordan-Wigner operator in a class of free-fermion models formulated on an infinite one-dimensional lattice. We represent this function in…
Spin dynamics in a one-dimensional ferromagnetic Bose gas
M. B. Zvonarev, V. V. Cheianov, T. Giamarchi
We investigate the propagation of spin excitations in a one-dimensional (1D) ferromagnetic Bose gas. While the spectrum of longitudinal spin waves in this system is sound-like, the…
Three-body local correlation function in the Lieb-Liniger model: bosonization approach
Vadim V. Cheianov, H. Smith, M. B. Zvonarev
We develop a method for the calculation of vacuum expectation values of local operators in the Lieb-Liniger model. This method is based on a set of new identities obtained using in…
Exact Results for Three-Body Correlations in a Degenerate One-Dimensional Bose Gas
Vadim V. Cheianov, H. Smith, M. B. Zvonarev
Motivated by recent experiments we derive an exact expression for the correlation function entering the three-body recombination rate for a one-dimensional gas of interacting boson…
Low-temperature crossover in the momentum distribution of cold atomic gases in one dimension
Vadim V. Cheianov, H. Smith, M. B. Zvonarev
The momentum distribution function for the two-component 1D gases of bosons and fermions is studied in the limit of strong interatomic repulsion. A pronounced reconstruction of the…
