Connection Problem for Painlevé Tau Functions
… obtain them from the relation of tau function to classical action which is a consequence of quasihomogeneity of corresponding Hamiltonians. We use these identities to solve the connection problem for generic solution of Painlev´e-III(D8) equation, and homogeneous Painlev´e-II equation. We …

Quantum action variable description of bound and scattering states
<p>We present generalized definitions of the classical and quantum radial action variables for both bound and scattering states of a particle moving in the Yukawa potential. The classical action variable is defined as an integral over a contour in the complex radial coordinate plane of the …

Legendrian intersections in twisted 1-jet bundles
… The proof involves defining an extension of the classical action functional in order to establish a variational principle for contact isotopies in the twisted sense, then carefully leveraging this to obtain special finite dimensional generating families, with explicitly calculable Morse index, …

Effective Actions for Strongly Interacting Fermionic Systems
… methods for calculating the effective action for fermionic systems featuring bosonic bound states (BBS) and spontaneous symmetry breaking (SSB). In a purely fermionic language proceeding into the SSB phase requires techniques beyond perturbation theory and renormalization group …

The Measurement Problem within Quantum Mechanics on a Non-commutative Plane
… where the noncommutative structure modifies the classical action and introduces damping of non-classical paths. In the macroscopic limit, this leads to the dominance of classical trajectories to the transition amplitude while suppressing those that deviate from such paths. In summary, this work …
