A term first coined by Mott back in 1968 a “pseudogap” is the depletion of the electronic
density of states at the Fermi level, and pseudogaps have been observed in many systems …

Explicit and implicit experimental evidence for charge density wave (CDW) presence in high‐
Tc superconducting oxides is analyzed. The theory of CDW superconductors is presented. It …

Mesa structures made of Bi2Sr2CaCu2O8+ δ high-temperature superconductor represent
stacks of atomic scale intrinsic Josephson junctions. They can be used for generation of high …

Low power efficiency is one of the main problems of terahertz (THz) sources, colloquially
known as “the THz gap.” In this work we present prototypes of THz devices based on …

I propose a new mechanism of intense high-frequency electromagnetic wave generation by
spatially uniform stacked Josephson junctions at zero magnetic field. The ac-Josephson …

Impedance matching and heat management are important factors influencing the
performance of terahertz sources. In this work we analyze thermal and radiative properties of …

I derive simple nonlocal dynamic boundary conditions, suitable for modeling of radiation
emission from stacked Josephson junctions in an arbitrary dynamic state. Coherent flux-flow …

We study a modification of the Plebanski action for general relativity, which leads to a
modified theory of gravity with 8 degrees of freedom. We show how the action can be …

Our recently discovered electrical doping technique allows a broad-range variation of carrier
concentration without changing the chemical composition. We show that it is possible to …

I solve numerically a full set of nonlinear kinetic balance equations for stacked Josephson
junctions, which allows analysis of strongly nonequilibrium phenomena. It is shown that …
