In parity-time-symmetric (PT-symmetric) Hamiltonian theory, the optimal evolution time can be reduced drastically and can even be zero. In this article, we report our experimental simulation of the fast evolution of a PT-symmetric Hamiltonian in a nuclear magnetic resonance quantum system. The experimental results demonstrate that the PT-symmetric Hamiltonian system can indeed evolve much faste...

with G=(g) and H = ( h ) being the average amplitudes while 6g and 6h are the fluctuating ones. Basic statistical assumptions of the nuclear cross section fluctuation theory [3-6] and the uncorrelation of 6S for different values of total angular momentum and parity lead to the independent normal distribution for complex compound-nucleus amplitudes 6g and ~h [7] F((Sg, 6h)= 1 exp ( [6912 Ibhl2 t...

Quantum-dot Cellular Automata (QCA) is a prominent paradigm that is considered to continue its dominance in thecomputation at deep sub-micron regime in nanotechnology. The QCA realizations of five-input Majority Voter based multilevel parity generator circuits have been introduced in recent years. However, no attention has been paid towards the QCA instantiation of the generic (n-bit) even and ...

The flavor violating μ − e conversion in nuclei is studied within the minimal supersymmetric standard model. We focus on the R-parity violating contributions at tree level including the trilinear and the bilinear terms in the superpotential as well as in the soft supersymmetry breaking sector. The nucleon and nuclear structure have consistently been taken into account in the expression of the μ...

OBJECTIVE To evaluate the association of different factors with postpartum depression. METHODS A prospective study conducted in the Department of Obstetrics and Gynecology, Medical College, Kolkata. Six thousand patients, 4-7 days postpartum, were interrogated using Edinburgh Postnatal Depression Scale (EPDS). Sociodemographic factors (age, parity, literacy, socioeconomic status, marital stat...

Reduced matrix elements and transition rates are calculated for all magnetic dipole (M1) transitions within 2l2l0 con gurations and for some 2l3l0 2l2l0 transitions in Be-like ions with nuclear charges ranging from Z = 4 to 100. Many-body perturbation theory (MBPT), including the Breit interaction, is used to evaluate retarded M1 matrix elements. The calculations start with a (1s) Dirac-Fock po...

All the R-parity violating tree-level contributions to the flavor violating μ − e conversion in a nucleus have been studied in the minimal supersymmetric model including the trilinear and the bilinear terms in the superpotential as well as in the soft supersymmetry breaking sector. In calculating the μ−−e− conversion rate the nucleon and nuclear structure have consistently been taken into accou...

Francium combines a heavy nucleus (Z = 87) with the simple atomic structure of alkalis and is a very promising candidate for precision tests of fundamental symmetries such as atomic parity non-conservation measurements. Fr has no stable isotopes, and the ISAC radioactive beam facility at TRIUMF, equipped with an actinide target, promises to provide record quantities of Fr atoms, up to 1010/s fo...

We study nuclear effects in the structure function F3 which describes the parity violating part of the charged-current neuitrino nucleon deep inelastic scattering. Starting from a covariant approach we derive a factorized expression for the nuclear structure function in terms of nuclear spectral function and off-shell nucleon structure functions valid for arbitrary momentum transfer Q and in th...
