The structure and dynamics of the actinide atoms from U to Lr is probed through the electron elastic scattering total cross sections (TCSs) calculated using Regge pole analysis. The crucial Regge trajectories probe electron attachment at the fundamen

We analyze the scaling of the condensation energy $E_{\Delta}$ divided by $\gamma$, $E_{\Delta}/\gamma\simeq N(0)\Delta_1^2/\gamma$, of both conventional superconductors and unconventional high-$T_c$ one, where $N(0)$ is the density of states, $\Delt

The recent paper (Science 382, 907 (2023)) is devoted to measurements of shot noise to probe excitations in nanowires of the heavy fermion (HF) metal $\rm YbRh_2Si_2$. The authors observed that shot noise is strongly suppressed, and claim that the su

In our short review, we consider the transport properties of strongly correlated Fermi systems like heavy fermion metals and high-$T_c$ superconductors. Their transport properties are defined by strong inter-particle interaction forming flat bands in

Condensed-matter community is involved in hot debate on the nature of quantum critical points (QCP) governing the low-temperature properties of heavy fermion metals. The smeared jump like behavior revealed both in the residual resistivity $\rho_0$ an

We demonstrate that an absolutely flat band retains the superconducting state at $T_c\to 0$. When $T_c>0$ the flat band disappears, since it must be modified by the superconducting state. Thus, a number of the results on ultra-strong coupling superco

Dramatically sharp resonances manifesting stable negative-ion formation characterize Regge pole-calculated low-energy electron elastic total cross sections (TCSs) of heavy multi-electron systems. The novelty of the Regge pole analysis is in the extra

P. W. Phillips, N. E. Hussey, P. Abbamonte (Review Article, 8 July 2022, eabh4273) consider heavy fermion (HF) metals and high-$T_c$ superconductors naming them strange metals. They analyze such features of strange metals as quantum criticality, Plan

We briefly review recent applications of the Regge pole analysis to low-energy E less than/equal to 10.0 eV electron elastic collisions with large multi-electron atoms and fullerene molecules. We then conclude with a demonstration of the sensitivity

Regge-pole calculated low-energy electron elastic total cross sections (TCSs) for complex heavy atoms and fullerene molecules are characterized generally by ground, metastable, and excited negative-ion formation, shape resonances and Ramsauer-Townsen
