Spectral stability of Schrödinger operators with subordinated complex potentials [PDF]
Journal of Spectral Theory, 2015 We prove that the spectrum of Schroedinger operators in three dimensions is purely continuous and coincides with the non-negative semiaxis for all potentials satisfying a form-subordinate smallness condition.

SCATTERING BY COMPLEX POTENTIALS WITHOUT COMPLEX TRAJECTORIES [PDF]
Le Journal de Physique Colloques, 1984 We briefly recall the concept of absorption in classical mechanics and we show that the quantum analogue is an imaginary potential proportional to _. The quantum phase shifts corresponding to this potential are calculated asymptotically to order _2.

Effective potential for complex Langevin equations [PDF]
Nuclear Physics B, 2009 We construct an effective potential for the complex Langevin equation on a lattice. We show that the minimum of this effective potential gives the space-time and Langevin time average of the complex Langevin field. The loop expansion of the effective potential is matched with the derivative expansion of the associated Schwinger-Dyson equation to ...

Bifurcation of Soliton Families from Linear Modes in Non‐ PT ‐Symmetric Complex Potentials [PDF]
, 2015 Continuous families of solitons in the nonlinear Schrödinger equation with non‐ PT ‐symmetric complex potentials and general forms of nonlinearity are studied analytically. Under a weak assumption, it is shown that stationary equations for solitons admit

Smooth elastic contact of cylinders by caustics: the contact length in the Brazilian disc test
Archives of Mechanics, 2013 The smooth contact of two elastic cylinders compressed against each other along a common generatrix is studied analytically and experimentally. The main objective is the quantification of the length of the contact arc. For the analytic study, the complex
