Thermodynamic Geometry Through Second Order Phase Transitions

Omer M. Basri, Oren Raz

A common approach to quantify excess dissipation in slowly driven thermodynamic processes is through the use of a Riemannian metric on the space of control parameters, where optima…

Shortcuts to adiabaticity across a separatrix

Roi Holtzman, Oren Raz, Christopher Jarzynski

Shortcuts to adiabaticity are strategies for conserving adiabatic invariants under non-adiabatic (i.e. fast-driving) conditions. Here, we show how to extend classical, Hamiltonian…

Similarities and Differences Between Nonequilibrium Steady States and Time-Periodic Driving in Diffusive Systems

Daniel M. Busiello, Christopher Jarzynski, Oren Raz

A system that violates detailed balance evolves asymptotically into a nonequilibrium steady state with non-vanishing currents. Analogously, when detailed balance holds at any insta…

How efficient is towing a cargo by a micro-swimmer?

Oren Raz, Alexander M. Leshansky

We study the properties of arbitrary micro-swimmers towing a passive load through a viscous liquid. The simple close-form expression for the dragging efficiency of a general micro-…

A geometric theory of swimming: Purcell's swimmer and its symmetrized cousin

J. E. Avron, O. Raz

We develop a qualitative geometric approach to swimming at low Reynolds number which avoids solving differential equations and uses instead landscape figures of two notions of curv…

A Comment on "Optimal Stroke Patterns for Purcell's Three-Link Swimmer"

O. Raz, J. E. Avron

For large enough aspect ratio, we find better stroke patterns then the patterns proposed by D. Tam and A.P.Hosoi in their letter to PRL "Optimal Stroke Patterns for Purcell's Three…

Swimming, Pumping and Gliding at low Reynolds numbers

J. E. Avron, O. Raz

Simple, linear equations relate microscopic swimmers to the corresponding gliders and pumps. They have the following set of consequences: The swimming velocity of free swimmers can…
