Spin Coherent-State Path Integrals and the Instanton Calculus
Anupam Garg, Evgueny Kochetov, Kee-Su Park +1
We use an instanton approximation to the continuous-time spin coherent-state path integral to obtain the tunnel splitting of classically degenerate ground states. We show that prov…
Phonons and Forces: Momentum versus Pseudomomentum in Moving Fluids
Michael Stone
I provide a pedagogical introduction to the notion of pseudomomentum for waves in a medium, and show how changes in pseudomomentum may sometimes be used to compute real forces. I t…
Magnus and Other Forces on Vortices in Superfluids and Superconductors
Michael Stone
This is the text of a talk which is to be published in the proceedings of the Joint APCTP-ICTP conference (Seoul National University Korea, May 26th-30th 1997).
Conductance of Luttinger-Liquid Wires Connected to Reservoirs
Dmitrii L. Maslov, Michael Stone
These are the lecture notes to be published in the Proceedings of XXXI Rencontres de Moriond conference ``Correlated Fermions and Transport in Mesoscopic Systems'', (20-27 January…
"Classical" Vortex Nucleation in Superflow Through Small Orifices
Ajit Srivastava, Michael Stone
We report on numerical solutions of the Gross-Pitaevskii equation for two-dimensional flow of a superfluid condensate through a small orifice. Above a critical velocity of about $3…
