We have studied the ground state of a fullerene-based magnet, the alpha;{'}-phase tetra-kis-(dimethylamino)-ethylene-C60 (alpha'-TDAE-C(60)), by electron spin resonance and magnetic torque measurements. Below T(N) = 7 K, nonparamagnetic field dependent resonances with a finite excitation gap (1.7 GHz) are observed along the a axis. Strong enhancement in their intensity as temperature is decreas...

The Metal-Ferroelectric-Semiconductor FET (MFSFET) device is structurally similar to a regular MOSFET device except that the gate material is composed of a ferroelectric material (PZT) normally sandwiched between two layers of silicon dioxide. Ferro models the PZT material with a set of four material parameters; the saturation polarization Ps, the remanent polarization Pr, the coercive field Ec...

In symmetric nuclear matter and stable nuclei one uses very often strictly phenomenological approaches, both in non-relativistic and relativistic formulation. In this contribution, a fully microscopic approach to nucleon-nucleon (NN) interactions in symmetric and asymmetric nuclear matter and extensions to hypernuclear matter will be discussed. Dirac-Brueckner theory is used to derive inmedium ...

We study a variant of the Cucker-Smale model where information between agents propagates with finite speed $ {{\mathfrak{c}}}>0 $. This leads to system functional differential equations state-dependent delay. prove that, if initially travel slower than {{\mathfrak{c}}} $, then discrete admits unique global solutions. Moreover, under generic assumption on influence function, we show that ther...
