Matrix Product Renormalization Group: Potential Universal Quantum Many-Body Solver
Masahiko G. Yamada, Takumi Sanno, Masahiro O. Takahashi +4
The density matrix renormalization group (DMRG) is a celebrated tensor network algorithm, which computes the ground states of one-dimensional quantum many-body systems very efficie…
BCS-BEC Crossover of Triplet Exciton Condensation in Bilayer Systems
Hidemaro Suwa, Shang-Shun Zhang, Cristian D. Batista
We study the BCS-BEC crossover phenomenon of triplet exciton condensation using a half-filled bilayer Hubbard model. We calculate the dynamical spin structure factor and the excito…
Reducing rejection exponentially improves Markov chain Monte Carlo sampling
Hidemaro Suwa
The choice of transition kernel critically influences the performance of the Markov chain Monte Carlo method. Despite the importance of kernel choice, guiding principles for optima…
Quasi-2D anomalous Hall Mott insulator of topologically engineered Jeff =1/2 electrons
Junyi Yang, Hidemaro Suwa, Derek Meyers +12
We investigate an experimental toy-model system of a pseudospin-half square-lattice Hubbard Hamiltonian in [(SrIrO3)1/(CaTiO3)1] to include both nontrivial complex hopping and mode…
Lifted directed-worm algorithm
Hidemaro Suwa
Nonreversible Markov chains can outperform reversible chains in the Markov chain Monte Carlo method. Lifting is a versatile approach to introducing net stochastic flow in state spa…
Nematicity and fractional magnetization plateaus induced by spin-lattice coupling in the classical kagome-lattice Heisenberg antiferromagnet
Masaki Gen, Hidemaro Suwa
We investigate the effect of spin-lattice coupling (SLC) on the magnetic properties of the classical kagome-lattice Heisenberg antiferromagnet (KHAF) using improved Monte Carlo upd…
