Nuclear force with LapH smearing
Takuya Sugiura, Yutaro Akahoshi, Tatsumi Aoyama +2
The nuclear forces are determined by combining the HAL QCD method and a new type of source smearing technique. The new smearing is a projection to a space spanned by the lowest-lyi…
Unitary -wave Fermi gas in one dimension
Hiroyuki Tajima, Shoichiro Tsutsui, Takahiro M. Doi +1
We elucidate universal many-body properties of a one-dimensional, two-component ultracold Fermi gas near the -wave Feshbach resonance. The low-energy scattering in this system c…
Complex Langevin study for polarons in an attractively interacting one-dimensional two-component Fermi gas
Takahiro M. Doi, Hiroyuki Tajima, Shoichiro Tsutsui
We investigate a polaronic excitation in a one-dimensional spin-1/2 Fermi gas with contact attractive interactions, using the complex Langevin method, which is a promising approach…
Low-Dimensional Fluctuations and Pseudogap in Gaudin-Yang Fermi Gases
Hiroyuki Tajima, Shoichiro Tsutsui, Takahiro M. Doi
Pseudogap is a ubiquitous phenomenon in strongly correlated systems such as high- superconductors, ultracold atoms and nuclear physics. While pairing fluctuations induci…
Distribution of solutions of the fastest apparent convergence condition in optimized perturbation theory and its relation to anti-Stokes lines
Shoichiro Tsutsui, Takahiro M. Doi
We discuss fundamental properties of the fastest apparent convergence (FAC) condition which is used as a variational criterion in optimized perturbation theory (OPT). We examine an…
Relating Quark Confinement and Chiral Symmetry Breaking in QCD
Hideo Suganuma, Takahiro M. Doi, Krzysztof Redlich +1
We study the relation between quark confinement and chiral symmetry breaking in QCD. Using lattice QCD formalism, we analytically express the various "confinement indicators", such…
