Experimental Test of the “Special State” Theory of Quantum Measurement
An experimental test of the “special state” theory of quantum measurement is proposed. It should be feasible with present-day laboratory equipment and involves a slightly elaborated Stern–Gerlach setup.

Quantum Effects on the Mesoscale
In different areas of mechanics, highly non-equilibrium processes are accompanied by self-organization of various type turbulent structures and localized inhomogeneities at intermediate scale between macro and micro levels.

In classical physics, there is a well-known theorem in which it is established that the energy per degree of freedom is the same. However, in quantum mechanics, due to the non-commutativity of some pairs of observables and the possibility of having non ...

Quantum mechanics concept assessment: Development and validation study
As part of an ongoing investigation of students’ learning in first semester upper-division quantum mechanics, we needed a high-quality conceptual assessment instrument for comparing outcomes of different curricular approaches.

Quantum mechanics has irked physicists ever since its conception more than 100 years ago. While some of the misgivings, such as it being unintuitive, are merely aesthetic, quantum mechanics has one serious shortcoming: it lacks a physical description of ...

Hidden Variables in Quantum Mechanics from the Perspective of Boltzmannian Statistical Mechanics
This paper examines no-hidden-variables theorems in quantum mechanics from the point of view of statistical mechanics. It presents a general analysis of the measurement process in the Boltzmannian framework that leads to a characterization of (in ...

Quantum statistical mechanics of electron gas in magnetic field
Electron eigenstates in a magnetic field are considered. Density of the probability current and an averaged magnetic moment are obtained. Density of states is investigated for two-dimensional electron in a circle that is bound by the infinite potential ...

Understanding quantum mechanics: a review and synthesis in precise language
This review, of the understanding of quantum mechanics, is broad in scope, and aims to reflect enough of the literature to be representative of the current state of the subject.

On the statistical mechanics of an adiabatic ensemble
Different descriptions of an adiabatic process based on statistical thermodynamics and statistical mechanics are discussed. Equality of the so-called adiabatic and isolated susceptibilities and its generalization as well as adiabatic invariants are ...

The Entropy-Based Quantum Metric
The von Neumann entropy S( D ^ ) generates in the space of quantum density matrices D ^ the Riemannian metric ds2 = −d2S( D ^ ), which is physically founded and which characterises the amount of quantum information lost by mixing D ...
