Pointer States and Decoherence in Quantum Unitarity: Energy Conservation for Weak Interaction Model
Kentaro Urasaki
The purpose of the present paper is to derive the pointer states of a macro-object using a simple perturbation method. We study the model Hamiltonian involving the weak interaction…
Classicality in Quantum Mechanics: model for pointer states and decoherence
Kentaro Urasaki
We have studied the emergence of classical states in the perturbative interaction model. The states which interact with many other degrees of freedom, such as the center of mass of…
A General Derivation of Pointer States: Decoherence and Classicality
Kentaro Urasaki
The purpose of the present study is to derive the pointer states of a macroscopic system interacting with its environment, under the general assumptions, i.e., without assuming any…
Mixture of Quantum States: Thermal and Interaction Inducing Decoherence
Kentaro Urasaki
In this study, we show that the interaction energy plays an important role on the quantum decoherence: If we pay attention to the oscillation phase factor, …
Quantum Decoherence and Pointer Basis: Dynamics in State Vectors
Kentaro Urasaki
It is well-known that the pointer basis of a quantum system satisfies the condition to diagonalize the interaction Hamiltonian between the subsystems. We show that this condition c…
Macroscopic Reality in Quantum Mechanics; Origin and Dissipation
Kentaro Urasaki
We study the connection between dissipation and reality in macroscopic quantum systems. We present the following scenario; if we consider the dynamics of a `partial' wave function,…
