We compare the thermodynamic dissipation described by (i) phase-volume loss with (ii) heat-transfer entropy production. Their equivalence is documented for computer simulations of the response of an ergodic harmonic oscillator to thermostated temperature gradients. In the simulations one or two thermostat variables control the kinetic energy or the kinetic energy and its fluctuation. All of the motion equations are time-reversible. We consider both strong and weak control variables. In every case, the time-averaged dissipative loss of phase-space volume coincides with the entropy produced by heat transfer. Linear-response theory nicely reproduces the small-gradient results obtained by computer simulation. The thermostats considered here are ergodic and provide simple dynamical models, some of them with as few as three ordinary differential equations, while remaining capable of reproducing Gibbs\u2019 canonical phase-space distribution and are precisely consistent with irreversible thermodynamics. <\/jats:p>","DOI":"10.1142\/s0218127416500899","type":"journal-article","created":{"date-parts":[[2016,5,31]],"date-time":"2016-05-31T06:25:31Z","timestamp":1464675931000},"page":"1650089","source":"Crossref","is-referenced-by-count":16,"title":["The Equivalence of Dissipation from Gibbs\u2019 Entropy Production with Phase-Volume Loss in Ergodic Heat-Conducting Oscillators"],"prefix":"10.1142","volume":"26","author":[{"given":"Puneet Kumar","family":"Patra","sequence":"first","affiliation":[{"name":"Advanced Technology Development Center, Department of Civil Engineering, Indian Institute of Technology, Kharagpur, West Bengal 721302, India"}]},{"given":"William Graham","family":"Hoover","sequence":"additional","affiliation":[{"name":"Ruby Valley Research Institute, Highway Contract 60, Box 601, Ruby Valley, Nevada 89833, USA"}]},{"given":"Carol Griswold","family":"Hoover","sequence":"additional","affiliation":[{"name":"Ruby Valley Research Institute, Highway Contract 60, Box 601, Ruby Valley, Nevada 89833, USA"}]},{"given":"Julien Clinton","family":"Sprott","sequence":"additional","affiliation":[{"name":"Department of Physics, University of Wisconsin \u2013 Madison, Wisconsin 53706, USA"}]}],"member":"219","published-online":{"date-parts":[[2016,5,30]]},"reference":[{"key":"S0218127416500899BIB001","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.42.5045"},{"key":"S0218127416500899BIB002","doi-asserted-by":"publisher","DOI":"10.1063\/1.166317"},{"key":"S0218127416500899BIB003","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevE.59.4000"},{"key":"S0218127416500899BIB004","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.31.1695"},{"key":"S0218127416500899BIB005","doi-asserted-by":"publisher","DOI":"10.1016\/0375-9601(95)00973-6"},{"key":"S0218127416500899BIB006","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-4371(97)00127-1"},{"key":"S0218127416500899BIB008","first-page":"109","volume":"23","author":"Hoover W.
