Heavy Fermionic Systems
Heavy fermion systems are a collection of materials whose properties are governed by a lattice that carries f-electron magnetic ions at crystalographic sites [Hewson]. The electrons within these f-orbitals interact magnetically with conduction electrons within the system. This state of affairs is reminiscent of the single ion Kondo problem that arises in other systems. In single ion Kondo syste...
متن کاملTransport properties of fermionic systems
We extend the method discovered by A Y Alekseev et al [1] to the case of fermions in external fields. A general formula for conductance G is proved. In the (1+1)-D case with symmetry at time reflection, it is shown that: G = e2/h +o ( α2 ) , where α is the strength of the external field. In (3+1)-D free case, it is checked that G = ne2/h, where n is the number of the filled energetic bands of t...
متن کاملFermionic systems with charge correlations
– In this paper, we show that a system of localized particles, satisfying the Fermi statistics and subject to finite-range interactions, can be exactly solved in any dimension. In fact, in this case it is always possible to find a finite closed set of eigenoperators of the Hamiltonian. Then, the hierarchy of the equations of motion for the Green’s functions eventually closes and exact expressio...
متن کاملRole of Kinetic Energy
Peak systolic pulmonary valvar pressure gradients are frequently seen in large intracardiac left-to-right shunt lesions. Conventionally, this has been attributed to "relative" pulmonic stenosis. Theoretical considerations suggest that this gradient is due to differences in expression of the total fluid energy. The side pressure, the downstream pressure, the end pressure, and the flow velocity i...
