Complex SUSY Transformations and the Painlev\'e IV Equation [PDF]
, 2012 In this paper we will explicitly work out the complex first-order SUSY transformation for the harmonic oscillator in order to obtain both real and complex new exactly-solvable potentials.

Pseudo Hermitian interactions in the Dirac Equation
, 2014 We consider $(2+1)$ dimensional massless Dirac equation in the presence of complex vector potentials. It is shown that such vector potentials (leading to complex magnetic fields) can produce bound states and the Dirac Hamiltonians are $\eta$-pseudo ...

Charging Symmetries and Linearizing Potentials for Einstein-Maxwell Dilaton-Axion Theory [PDF]
, 1998 We derive a set of complex potentials which linearize the action of charging symmetries of the stationary Einstein-Maxwell dilaton-axion theory.Comment: 10 pages in ...

Schrödinger Operators with Complex Sparse Potentials
Communications in Mathematical Physics, 2022 AbstractWe establish quantitative upper and lower bounds for Schrödinger operators with complex potentials that satisfy some weak form of sparsity. Our first result is a quantitative version of an example, due to S. Bögli (Commun Math Phys 352:629–639, 2017), of a Schrödinger operator with eigenvalues accumulating to every point of the essential ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

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.

Coherent perfect absorption with and without lasing in complex potentials [PDF]
, 2014 We prove that coherent perfect absorption (CPA) without lasing is not possible in the PT-symmetric domain because the S-matrix is such that | det S ( ± k ) | = 1 ?> . We study coherent scattering from three complex potentials, one solved analytically and
