Continuum Scaling from Large Mass Expansion on the Lattice: Delta Expansion Applied to the Anharmonic Oscillator
Hideko Hashiguchi, Keisuke Hoshino, Hirofumi Yamada
We dilate the scaling region of the lattice anharmonic oscillator at strong coupling by introducing the parameter delta. Performing expansion in delta, the calculation of the mass…

Delta Expansion on the Lattice and Dilated Scaling Region
Hirofumi Yamada
A new kind of delta expansion is applied on the lattice to the d=2 non-linear sigma model at N=infinity and N=1 which corresponds to the Ising model. We introduce the parameter del…

Kaon-condensed hypernuclei as highly dense self-bound objects
Takumi Muto
The structure of -condensed hypernuclei, which may be produced in the laboratory in strangeness-conserving processes, is investigated using an effective chiral Lagrangian for…
