Non-Hermitian Quantum Fermi Accelerator
Andreas Fring, Takano Taira
We exactly solve a quantum Fermi accelerator model consisting of a time-independent non-Hermitian Hamiltonian with time-dependent Dirichlet boundary conditions. A Hilbert space for…
Localization and limit laws of a three-state alternate quantum walk on a two-dimensional lattice
Takuya Machida, C. M. Chandrashekar
A two-dimensional discrete-time quantum walk (DTQW) can be realized by alternating a two-state DTQW in one spatial dimension followed by an evolution in the other dimension. This w…
A limit law of the return probability for a quantum walk on a hexagonal lattice
Takuya Machida
A return probability of random walks is one of the interesting subjects. As it is well known, the return probability strongly depends on the structure of the space where the random…
Self-avoiding quantum walks: realisations in subspaces and limit theorems
Takuya Machida, C. M. Chandrashekar, Norio Konno +1
While completely self-avoiding quantum walks have the distinct property of leading to a trivial unidirectional transport of a quantum state, an interesting and non-trivial dynamics…
A quantum walk with a delocalized initial state: contribution from a coin-flip operator
Takuya Machida
A unit evolution step of discrete-time quantum walks is determined by both a coin-flip operator and a position-shift operator. The behavior of quantum walkers after many steps deli…
Visualization of superposition of macroscopically distinct states
Tomoyuki Morimae, Akira Shimizu
We propose a method of visualizing superpositions of macroscopically distinct states in many-body pure states. We introduce a visualization function, which is a coarse-grained quas…
On the Relationship between Convex Bodies Related to Correlation Experiments with Dichotomic Observables
David Avis, Hiroshi Imai, Tsuyoshi Ito
In this paper we explore further the connections between convex bodies related to quantum correlation experiments with dichotomic variables and related bodies studied in combinator…
