The quantum partition function at finite temperature requires computing the trace of the imaginary time propagator. For numerical and Monte Carlo calculations, the propagator is usually split into its kinetic and potential parts. A higher-order splitting will result in a higher-order convergent algorithm. At imaginary time, the kinetic energy propagator is usually the diffusion Green's function...

Abstract. Let −D < −4 denote a fundamental discriminant which is either odd or divisible by 8, so that the canonical Hecke character of Q( √ −D) exists. Let d be a fundamental discriminant prime to D. Let 2k− 1 be an odd natural integer prime to the class number of Q( √ −D). Let χ be the twist of the (2k − 1)th power of a canonical Hecke character of Q( √ −D) by the Kronecker’s symbol n 7→ ( d ...

The recent detection by the BICEP2 collaboration of a high level of tensor modes seems to exclude the Starobinsky model of inflation. In this paper we show that this conclusion can be avoided: one can embed the Starobinsky model in supergravity and identify the inflaton field with the imaginary (instead of the real) part of the chiral scalaron multiplet in its formulation. Once coupled to matte...

some of the islamic philosophers such as farabi and mulla sadra supporting the belief in sacred and divine revelation, began to give a philosophical explanation in the field. in philosophical explanation of revelation, revealed facts can be divided into two: general and particular, perceived respectively by the prophet`s intellect and imagination. both the philosophers when explaining divine re...

Abelian class group Cl(D) of imaginary quadratic order with odd squarefree discriminant D is used in public key cryptosystems, based on discrete logarithm problem in class group and in cryptosystems, based on isogenies of elliptic curves. Discrete logarithm problem in Cl(D) is hard if #Cl(D) is prime or has large prime divisor. But no algorithms for generating such D are known. We propose proba...

We use symmetry arguments and simple model systems to describe the conversion of the singlet state of parahydrogen into an oscillating sample magnetization at zero magnetic field. During an initial period of free evolution governed by the scalar-coupling Hamiltonian HJ, the singlet state is converted into scalar spin order involving spins throughout the molecule. A short dc pulse along the z ax...
