Dominance and equivalence for states on -algebras: Quasi-Invariant states
Ameur Dhahri, Francesco Fidaleo, Chul Ki Ko +1
We study the noncommutative generalization of measure-theoretic dominance and equivalence of states on -algebras to explore quasi-invariance under group actions. For a dominat…
Martingales associated with strongly quasi-invariant states
Ameur Dhahri, Chul Ki Ko, Hyun Jae Yoo
We discuss the martingales in relevance with -strongly quasi-invariant states on a -algebra , where is a separable locally compact group of -automorphism…
Group of automorphisms for strongly quasi invariant states
Ameur Dhahri, Chul Ki Ko, Hyun Jae Yoo
For a -automorphism group on a - or von Neumann algebra, we study the -quasi invariant states and their properties. The -quasi invariance or -strongly quasi in…
The Generalized Fibonacci Oscillator as an Open Quantum System
Franco Fagnola, Chul Ki Ko, Hyun Jae Yoo
We consider an open quantum system with Hamiltonian whose spectrum is given by a generalized Fibonacci sequence weakly coupled to a Boson reservoir in equilibrium at inverse…
Quadratic Open Quantum Harmonic Oscillator
Ameur Dhahri, Franco Fagnola, Hyunjae Yoo
We study the quantum open system evolution described by a Gorini-Kossakowski-Sudarshan-Lindblad generator with creation and annihilation operators arising in Fock representations o…
Stopping times in the game Rock-Paper-Scissors
Kyeonghoon Jeong, Hyun Jae Yoo
In this paper we compute the stopping times in the game Rock-Paper-Scissors. By exploiting the recurrence relation we compute the mean values of stopping times. On the other hand,…
