Semiclassical Fundamental Solutions

چکیده
whenever the convolution makes sense. If boundary conditions are imposed, one needs to modify the approach in order to be able to take care of them, but the basic principle remains the same. On the other hand, we have a fully abstract approach based on operator sums. Letting PDO1 and PDO2 be the differential operators which act on the first m variables and on the second n ones, respectively, one tries to construct the solution operator (PDO1 +PDO2)−1 by using functional calculus formulae. Choosing an integral representation based on the resolvents of the two operators, one can obtain results of

The high energy semiclassical asymptotics of loci of roots of fundamental solutions for polynomial potentials
In the case of polynomial potentials all solutions to 1-D Schrödinger equation are entire functions totally determined by loci of their roots and their behaviour at infinity. In this paper a description of the first of the two properties is given for fundamental solutions for the high complex energy limit when the energy is quantized or not. In particular due to the fact that the limit consider...
متن کاملGreens Functions for the Wave Equation
I gather together known results on fundamental solutions to the wave equation in free space, and Greens functions in tori, boxes, and other domains. From this the corresponding fundamental solutions for the Helmholtz equation are derived, and, for the 2D case the semiclassical approximation interpreted back in the time-domain. Utility: scarring via time-dependent propagation in cavities; Math 4...
متن کاملBorel Summable Solutions to 1-dim Schroedinger equation
It is shown that so called fundamental solutions which semiclassical expansions have been established earlier to be Borel summable to the solutions themselves [1] appear also as the unique solutions to 1-dim Schrödinger equation having this property. This justify the exceptional role the fundamental solutions play in 1-dim quantum mechanics [1, 2, 6, 9]. PACS number(s): 03.65.-W , 03.65.Sq , 02...
متن کاملBorel Summable Solutions to 1D Schrödinger equation
It is shown that so called fundamental solutions the semiclassical expansions of which have been established earlier to be Borel summable to the solutions themselves appear also to be the unique solutions to the 1D Schrödinger equation having this property. Namely, it is shown in this paper that for the polynomial potentials the Borel function defined by the fundamental solutions can be conside...
متن کاملChange of Variables as Borel Resummation of Semiclassical Series
It is shown that a change of variable in 1-dim Schrödinger equation applied to the Borel summable fundamental solutions [8, 9] is equivalent to Borel resummation of the fundamental solutions multiplied by suitably chosen h̄-dependent constant. This explains why change of variable can improve JWKB formulae [11]. It is shown also that a change of variable alone cannot provide us with the exact JWK...
