Phonons and structures of tetracene polymorphs at low temperature and high pressure
Elisabetta Venuti, Raffaele Guido Della Valle, Luca Farina +3
Crystals of tetracene have been studied by means of lattice phonon Raman spectroscopy as a function of temperature and pressure. Two different phases (polymorphs I and II) have bee…
Calculation of Feynman integrals by difference equations
S. Laporta
In this paper we describe a method of calculation of master integrals based on the solution of systems of difference equations in one variable. Various explicit examples are given,…
A uniform approach to constraint-solving for lists, multisets, compact lists, and sets
Agostino Dovier, Carla Piazza, Gianfranco Rossi
Lists, multisets, and sets are well-known data structures whose usefulness is widely recognized in various areas of Computer Science. These data structures have been analyzed from…
cTI: A constraint-based termination inference tool for ISO-Prolog
Fred Mesnard, Roberto Bagnara
We present cTI, the first system for universal left-termination inference of logic programs. Termination inference generalizes termination analysis and checking. Traditionally, a t…
Static polarizability of molecular materials: environmental and vibrational contributions
Francesca Terenziani, Anna Painelli, Zoltan G. Soos
Modeling the dielectric behavior of molecular materials made up of large pi-conjugated molecules is an interesting and complex task. Here we address linear polarizabilities, and th…
Algebraic Algorithms in Perturbative Calculations
Stefan Weinzierl
I discuss algorithms for the evaluation of Feynman integrals. These algorithms are based on Hopf algebras and evaluate the Feynman integral to (multiple) polylogarithms.
