Magnetic ground states of highly doped two-leg Hubbard ladders with a particle bath
Hiroaki Onishi, Seiji Miyashita
We investigate the ground-state magnetism of a Hubbard model in a system consisting of a main frame (subsystem) and a particle bath (center sites). The hole doping in the main fram…
Optimization of conveyance of quantum particles by moving potential well
Satoshi Morita, Yoshiaki Teranishi, Seiji Miyashita
Quantum mechanical control of the position of a particle by using a trapping potential well is an important problem for the manipulation of a quantum particle. We study the probabi…
Anisotropy of the molecular magnet V spin Hamiltonian detected by high-field electron spin resonance
M. Martens, J. van Tol, N. S. Dalal +7
The molecular compound K[VAsO(HO)] 8HO, in short V, has shown important quantum effects such as coherent spin oscillations.…
Novel symmetry-broken phase in a driven cavity system in the thermodynamic limit
Tatsuhiko Shirai, Takashi Mori, Seiji Miyashita
We study non-equilibrium stationary states of a cavity system consisting of many atoms interacting with a quantized cavity field mode, under a driving field in a dissipative enviro…
Quantum simulations and experiments on Rabi oscillations of spin qubits: intrinsic {\sl vs} extrinsic damping
H. De Raedt, B. Barbara, S. Miyashita +3
Electron Paramagnetic Resonance experiments show that the decay of Rabi oscillations of ensembles of spin qubits depends noticeably on the microwave power and more precisely on the…
Proposal for an interference experiment to test the applicability of quantum theory to event-based processes
K. Michielsen, Th. Lippert, M. Richter +3
We analyze a single-particle Mach-Zehnder interferometer experiment in which the path length of one arm may change (randomly or systematically) according to the value of an externa…
