Finite-Size Scaling for Quantum Criticality above the Upper Critical Dimension: Superfluid-Mott-Insulator Transition in Three Dimensions
Yasuyuki Kato, Naoki Kawashima
Validity of modified finite-size scaling above the upper critical dimension is demonstrated for the quantum phase transition whose dynamical critical exponent is . We consider…
Strong-coupling expansion for the momentum distribution of the Bose Hubbard model with benchmarking against exact numerical results
J. K. Freericks, H. R. Krishnamurthy, Yasuyuki Kato +2
A strong-coupling expansion for the Green's functions, self-energies and correlation functions of the Bose Hubbard model is developed. We illustrate the general formalism, which in…
Direct mapping of the finite temperature phase diagram of strongly correlated quantum models
Qi Zhou, Yasuyuki Kato, Naoki Kawashima +1
Optical lattice experiments, with the unique potential of tuning interactions and density, have emerged as emulators of nontrivial theoretical models that are directly relevant for…
