Is quantum mechanics really timeless?
(Nova Science Publishers, 2019)
In this paper, I shall put into question a widely-held claim in the discussion on the arrow of time in quantum mechanics: since the Schrödinger equation is evidently time-reversal invariant, there is no room for a fundamental ...
Numerical time development in quantum mechanics using a reduced Hilbert space approach
(Open Source Physics, 2011)
A formal framework for the study of the notion of undefined particle number in quantum mechanics
(Springer, 2015-01)
It is usually stated that quantum mechanics presents problems with the identity of particles, the most radical position—supported by E. Schrödinger—asserting that elementary particles are not individuals. But the subject ...
Quantum-mechanical energy eigenstates and their superpositions

Quantum-mechanical energy eigenstates and their superpositions

Symmetry transformations in quantum mechanics
(Società Italiana di Fisica, 1987)
We introduce a new definition of symmetry transformations in quantum mechanics which contains the textbook definition as a special case. We find several conserved quantities associated with one (nonunitary) symmetry ...
Thermodynamics and Steady State of Quantum Motors and Pumps Far from Equilibrium
(MDPI, 2019-08-23)
In this article, we briefly review the dynamical and thermodynamical aspects of different forms of quantum motors and quantum pumps. We then extend previous results to provide new theoretical tools for a systematic study ...
Quantum confinement in hydrogen bond
(Wiley-Blackwell, 2015-06-15)
In this work, the quantum confinement effect is proposed as the cause of the displacement of the vibrational spectrum of molecular groups that involve hydrogen bonds. In this approach, the hydrogen bond imposes a space ...
Entropic relations for retrodicted quantum measurements
(American Physical Society, 2018-01)
Given an arbitrary measurement over a system of interest, the outcome of a posterior measurement can be used for improving the statistical estimation of the system state after the former measurement. Here, we realize an ...
