Query: Ab initio relaxation times and time-dependent Hamiltonians within the
  steepest-entropy-ascent quantum thermodynamic framework   Quantum systems driven by time-dependent Hamiltonians are considered here
within the framework of steepest-entropy-ascent quantum thermodynamics (SEAQT)
and used to study the thermodynamic characteristics of such systems. In doing
so, a generalization of the SEAQT framework valid for all such systems is
provided, leading to the development of an ab initio physically relevant
expression for the intra-relaxation time, an important element of this
framework and one that had as of yet not been uniquely determined as an
integral part of the theory. The resulting expression for the relaxation time
is valid as well for time-independent Hamiltonians as a special case and makes
the description provided by the SEAQT framework more robust at the fundamental
level. In addition, the SEAQT framework is used to help resolve a fundamental
issue of thermodynamics in the quantum domain, namely, that concerning the
unique definition of process-dependent work and heat functions. The
developments presented lead to the conclusion that this framework is not just
an alternative approach to thermodynamics in the quantum domain but instead one
that uniquely sheds new light on various fundamental but as of yet not
completely resolved questions of thermodynamics.
