  1. 1. Non-equilibrium thermodynamics at the microscopic scales

    Author : Sreekanth K Manikandan; Supriya Krishnamurthy; David Lacoste; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Non-equilibrium statistical Physics; entropy production; teoretisk fysik; Theoretical Physics;

    Abstract : An inherent feature of small systems in contact with thermal reservoirs, be it a pollen grain in water, or an active microbe flagellum, is fluctuations. Even with advanced microscopic techniques, distinguishing active, non-equilibrium processes defined by a constant dissipation of energy to the environment from passive, equilibrium processes is a very challenging task and a vastly developing field of research.

  2. 2. Finite-time  non-equilibrium thermodynamics of a colloidal particle

    Author : Sreekanth K. Manikandan; Supriya Krishnamurthy; Jens H. Bardarson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : In this thesis we have thermodynamically characterized finite time processes performed on a colloidal particle, kept in contact with thermal reservoir(s). Thermodynamic processes are implemented on the colloidal particle by systematically changing the confining potential in a time dependent way, according to an external driving protocol or by controlling the environmental conditions over a finite duration.

  4. 4. Magnetic materials with tunable thermal, electrical, and dynamic properties : An experimental study of magnetocaloric, multiferroic, and spin-glass materials

    Author : Matthias Hudl; Per Nordblad; DD Sarma; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetocalorics; multiferroics; spin glasses; magnetization; polarization; spin-dimensionality; Fasta tillståndets fysik; Solid State Physics;

    Abstract : This thesis concerns and combines the results of experimental studies of magnetocaloric, multiferroic and spin-glass materials, using SQUID magnetometry as the main characteriza-tion technique. The magnetocaloric effect offers an interesting new technology for cooling and heating applications.
