Field Theory of Borromean Super-counterfluids
Anatoly Kuklov, Leo Radzihovsky, Boris Svistunov
We introduce a class of dynamical field theories for -component "Borromean" () super-counterfluid order, naturally formulated in terms of inter-species bosonic fields $…

Superconductivity of bipolarons from quadratic electron-phonon interaction
Zhongjin Zhang, Anatoly Kuklov, Nikolay Prokof'ev +1
In systems with linear electron-phonon interaction (EPI), bound states of polarons, or bipolarons, form by gaining energy from the lattice deformation. The quadratic EPI case is fu…
