Thermodynamics connects our knowledge of the world to capability manipulate and thus control it. This crucial role is exemplified by third law thermodynamics, Nernst's unattainability principle, which states that infinite resources are required cool a system absolute zero temperature. But what these how should they be utilized? And does this relate Landauer's principle famously information ther...

By establishing a relation between information erasure and continuous phase transitions we generalize the Landauer bound to analog computing systems. The entropy production per degree of freedom during erasure of an analog variable (reset to standard value) is given by the logarithm of the configurational volume measured in units of its minimal quantum. As a consequence, every computation has t...

We establish well-defined limits in which the time-dependent electronic currents across a molecular junction subject to a fluctuating environment can be quantitatively captured via the Landauer steady-state approximation. For this, we calculate the exact time-dependent non-equilibrium Green's function (TD-NEGF) current along a model two-site molecular junction, in which the site energies are su...

This article discusses the concept of information and its intimate relationship with physics. After an introduction of all the necessary quantum mechanical and information theoretical concepts we analyse Landauer’ s principle which states that the erasure of information is inevitably accompanied by the generation of heat. We employ this principle to rederive a number of results in classical and...

in this study, polyaniline molecule (emeraldine base) is modeled as a molecular wire and the effects of the metal/molecule coupling strength and the molecule length on the current-voltage (i-v) characteristics are numerically investigated. using a tight-binding hamiltonian model, the methods based on non-equilibrium green’s function theory, landauer formalism and newns-anderson model, our calcu...
