Statistical Mechanics of Vibration-Induced Compaction of Powders [PDF]

, 1998
We propose a theory which describes the density relaxation of loosely packed, cohesionless granular material under mechanical tapping. Using the compactivity concept we develope a formalism of statistical mechanics which allows us to calculate the ...

Statistical Theory of Spin Relaxation and Diffusion in Solids [PDF]

, 2006
A comprehensive theoretical description is given for the spin relaxation and diffusion in solids. The formulation is made in a general statistical-mechanical way. The method of the nonequilibrium statistical operator (NSO) developed by D. N.

Quantum spin liquid at finite temperature: proximate dynamics and persistent typicality [PDF]

, 2019
Quantum spin liquids are long-range entangled states of matter with emergent gauge fields and fractionalized excitations. While candidate materials, such as the Kitaev honeycomb ruthenate $\alpha$-RuCl$_3$, show magnetic order at low temperatures $T ...

Free energies in the presence of electric and magnetic fields

, 2004
We discuss different free energies for materials in static electric and magnetic fields. We explain what the corresponding Hamiltonians are, and describe which choice gives rise to which result for the free energy change, dF, in the thermodynamic ...

Quasi-equilibrium nonadditivity [PDF]

, 2014
The possibility that a short-range interacting system exhibits nonadditivity is investigated. After the discussion on the precise definition of additivity and its consequence, we show that it is possible when the system is in a quasi-equilibrium state by

Enhancement of magnetic anisotropy barrier in long range interacting spin systems

, 2012
Magnetic materials are usually characterized by anisotropy energy barriers which dictate the time scale of the magnetization decay and consequently the magnetic stability of the sample.

Topology by Design in Magnetic nano-Materials: Artificial Spin Ice

, 2017
Artificial Spin Ices are two dimensional arrays of magnetic, interacting nano-structures whose geometry can be chosen at will, and whose elementary degrees of freedom can be characterized directly.

A building block for hardware belief networks

, 2016
Belief networks represent a powerful approach to problems involving probabilistic inference, but much of the work in this area is software based utilizing standard deterministic hardware based on the transistor which provides the gain and directionality ...

Theories of Matter: Infinities and Renormalization [PDF]

, 2010
This paper looks at the theory underlying the science of materials from the perspectives of physics, the history of science, and the philosophy of science. We are particularly concerned with the development of understanding of the thermodynamic phases of
