Super Kähler oscillator from SU(2|1) superspace
E. Ivanov, S. Sidorov
We construct a new version of the worldline SU(2|1) superspace as a deformation of the standard N =4, d=1 superspace and show that it naturally provides off- and on-shell descripti…
N=4 mechanics with diverse (4,4,0) multiplets: explicit examples of HKT, CKT, and OKT geometries
Sergey Fedoruk, Evgeny Ivanov, Andrei Smilga
We present simple models of N=4 supersymmetric mechanics with ordinary and mirror linear (4,4,0) multiplets that give a transparent description of HKT, CKT, and OKT geometries. The…
Deformed Supersymmetric Mechanics
E. Ivanov, S. Sidorov
Motivated by a recent interest in curved rigid supersymmetries, we construct a new type of N=4, d=1 supersymmetric systems by employing superfields defined on the cosets of the sup…
Bispinor Auxiliary Fields in Duality-Invariant Electrodynamics Revisited: The U(N) Case
E. A. Ivanov, B. M. Zupnik
We update and detail the formulation of the duality-invariant systems of N interacting abelian gauge fields with N auxiliary bispinor fields added. In this setting, the self-dualit…
Auxiliary superfields in N=1 supersymmetric self-dual electrodynamics
Evgeny Ivanov, Olaf Lechtenfeld, Boris Zupnik
We construct the general formulation of N=1 supersymmetric self-dual abelian gauge theory involving auxiliary chiral spinor superfields. Self-duality in this context is just U(N) i…
Quasicomplex N=2, d=1 Supersymmetric Sigma Models
Evgeny A. Ivanov, Andrei V. Smilga
We derive and discuss a new type of N=2 supersymmetric quantum mechanical sigma models which appear when the superfield action of the (1,2,1) multiplets is modified by adding an im…
