We study the electron temperature profiles for an inhomogeneous flow in hydrodynamic regime. assume that inhomogeneity is due to a weakly nonuniform distribution of momentum relaxation time within spherically constricted area. show profile dramatically depends on drive strength and viscosity liquid. In absence viscosity, Landauer-dipole-like distribution, asymmetrically deformed along current b...

Using the operational framework of completely positive, trace preserving operations and thermodynamic fluctuation relations, we derive a lower bound for the heat exchange in a Landauer erasure process on a quantum system. Our bound comes from a nonphenomenological derivation of the Landauer principle which holds for generic nonequilibrium dynamics. Furthermore, the bound depends on the nonunita...

Landauer’s Principle asserts that there is an unavoidable cost in thermodynamic entropy creation when data is erased. It is usually derived from incorrect assumptions, most notably, that erasure must compress the phase space of a memory device or that thermodynamic entropy arises from the probabilistic uncertainty of random data. Recent work seeks to prove Landauer’s Principle without using the...

Using the Landauer formula and a random matrix model, we investigate the autocorrelation function of the conductance versus magnetic

We introduce a fast and highly efficient physically realizable bit swap. Employing readily available scalable Josephson junction microtechnology, the design implements recently introduced paradigm of momentum computing. Its nanosecond speeds sub-Landauer thermodynamic efficiency arise from dynamically storing memory in degrees freedom. As such, during swap, microstate distribution is never near...
