Common field-induced quantum critical point in high-temperature superconductors and heavy-fermion metals
V. R. Shaginyan, M. Ya. Amusia, K. G. Popov +1
High-temperature superconductors (HTSC) and heavy-fermion (HF) metals exhibit extraordinary properties. They are so unusual that the traditional Landau paradigm of quasiparticles d…
Endohedral resonances: modification of atomic photoionization by the fullerenes shell
M. Ya. Amusia, L. V. Chernysheva
We discuss the complicated resonance structure of the endohedral atom photoionization cross section. Very strong enhancement and interference patterns in the photoionization cross-…
Destruction and Resurrection of Atomic Giant resonances in Endohedral Atoms A@C60
M. Ya. Amusia, A. S. Baltenkov, L. V. Chernysheva
It is demonstrated that in photoabsorption by endohedral atoms some atomic Giant resonances are almost completely destroyed while the others are totally preserved due to different…
On photoionization of the subvalent subshells of noble gas endohedral atoms
M. Ya. Amusia, A. S. Baltenkov, L. V. Chernysheva
We demonstrate strong interference patterns in the photoionization cross-section of the subvalent subshells of noble gas (NG) endohedral atoms NG@F. This interference is a result o…
On the angular distribution and spin polarization of the photoelectrons from semi-filled shell atoms
M. Ya. Amusia, L. V. Chernysheva
We present here the results of calculations of photoelectrons' angular anisotropy and spin-polarization parameters for a number of semi-filled shell atoms. We consider ionization o…
Comment on "Evidence for Coexistence of the Gap and the Pseudogap in Bi-2212 from Intrinsic Tunneling Spectroscopy"
M. Ya. Amusia, V. R. Shaginyan
It is argued that the superconducting and pseudogaps represent different coexisting phenomena, and this observation speaks against the precursor-superconductivity scenario of the p…
