Numerical simulations of quantum clock for measuring tunneling times
Fumika Suzuki, William G. Unruh
We numerically study two methods of measuring tunneling times using a quantum clock. In the conventional method using the Larmor clock, we show that the Larmor tunneling time can b…
Anderson localization of composite particles
Fumika Suzuki, Mikhail Lemeshko, Wojciech H. Zurek +1
We investigate the effect of coupling between translational and internal degrees of freedom of composite quantum particles on their localization in a random potential. We show that…
A Stern-Gerlach separator of chiral enantiomers based on the Casimir-Polder potential
Fumika Suzuki, Takamasa Momose, Stefan Yoshi Buhmann
We propose a method to separate enantiomers using parity violation in the Casimir-Polder potential between chiral mirrors and chiral molecules. The proposed setup involves a molecu…
Quantum tunneling of composite object coupled with quantized radiation field
Fumika Suzuki, Friedemann Queisser
We study quantum tunneling of a composite object, which has a dipole or quadrupole moment coupled with quantized (photon or gravitational) radiation field, through a δ potential ba…
Fractional Moment Methods for Anderson Localization with SAW Representation
Fumika Suzuki
The Green's function contains much information about physical systems. Mathematically, the fractional moment method (FMM) developed by Aizenman and Molchanov connects the Green's f…
Scattering of a composite quasiparticle by an impurity on a lattice
Fumika Suzuki, Marina Litinskaya, William G. Unruh
We study scattering of a composite quasiparticle, which possesses a degree of freedom corresponding to relative separation between two bound excitations, by a delta-like impurity p…
Environmental gravitational decoherence and a tensor noise model
Fumika Suzuki, Friedemann Queisser
We discuss decrease of coherence in a massive system due to the emission of gravitational waves. In particular we investigate environmental gravitational decoherence in the context…
Homotopy and Path Integrals
Fumika Suzuki
This is an introductory review of the connection between homotopy theory and path integrals, mainly focus on works done by Schulman [23] that he compared path integral on SO(3) and…
