Boris Ionovich Shklovskii (born 1944) is a theoretical physicist, at the William I Fine Theoretical Physics Institute, University of Minnesota, specializing in condensed matter. Shklovskii earned his A.B. degree in Physics, in 1966 and a Ph.D. in condensed matter theory, in 1968 from Leningrad University. [1]
Shklovskii is known for the Efros–Shklovskii variable-range hopping conductivity, a model for the temperature dependence of the electrical conductivity in the variable-range hopping regime. [2] He has also made important contributions to the theory of the Quantum Hall effect (explaining the structure of conducting edge channels [3] and predicting the formation of Quantum Hall stripe and bubble phases [4] [5] ) and to the theory of macromolecules (developing the theory of electrostatic charge inversion [6] [7] ).
Shklovskii was awarded the Landau Prize of Academy of Sciences of USSR in 1986, the A.S. Fine Chair in Theoretical Physics in 1990, [1] [8] and was elected a fellow of the American Physical Society in 1997. [9]
In 2018, he received the 2019 Oliver E. Buckley Condensed Matter Physics Prize for "pioneering research in the physics of disordered materials and hopping conductivity" together with Alexei L. Efros and Elihu Abrahams. [10]
In 2023 he was elected to the National Academy of Sciences. [11]
The Wannier functions are a complete set of orthogonal functions used in solid-state physics. They were introduced by Gregory Wannier in 1937. Wannier functions are the localized molecular orbitals of crystalline systems.
PLATO is a suite of programs for electronic structure calculations. It receives its name from the choice of basis set used to expand the electronic wavefunctions.
Spin-density wave (SDW) and charge-density wave (CDW) are names for two similar low-energy ordered states of solids. Both these states occur at low temperature in anisotropic, low-dimensional materials or in metals that have high densities of states at the Fermi level . Other low-temperature ground states that occur in such materials are superconductivity, ferromagnetism and antiferromagnetism. The transition to the ordered states is driven by the condensation energy which is approximately where is the magnitude of the energy gap opened by the transition.

Marvin Lou Cohen is an American–Canadian theoretical physicist. He is a physics professor at the University of California, Berkeley. Cohen is a leading expert in the field of condensed matter physics. He is widely known for his seminal work on the electronic structure of solids.
Quantum dimer models were introduced to model the physics of resonating valence bond (RVB) states in lattice spin systems. The only degrees of freedom retained from the motivating spin systems are the valence bonds, represented as dimers which live on the lattice bonds. In typical dimer models, the dimers do not overlap.
First introduced by M. Pollak, the Coulomb gap is a soft gap in the single-particle density of states (DOS) of a system of interacting localized electrons. Due to the long-range Coulomb interactions, the single-particle DOS vanishes at the chemical potential, at low enough temperatures, such that thermal excitations do not wash out the gap.

In quantum many-body physics, topological degeneracy is a phenomenon in which the ground state of a gapped many-body Hamiltonian becomes degenerate in the limit of large system size such that the degeneracy cannot be lifted by any local perturbations.
Scissors Modes are collective excitations in which two particle systems move with respect to each other conserving their shape. For the first time they were predicted to occur in deformed atomic nuclei by N. LoIudice and F. Palumbo, who used a semiclassical Two Rotor Model, whose solution required a realization of the O(4) algebra that was not known in mathematics. In this model protons and neutrons were assumed to form two interacting rotors to be identified with the blades of scissors. Their relative motion (Fig.1) generates a magnetic dipole moment whose coupling with the electromagnetic field provides the signature of the mode.
The semicircle law, in condensed matter physics, is a mathematical relationship that occurs between quantities measured in the quantum Hall effect. It describes a relationship between the anisotropic and isotropic components of the macroscopic conductivity tensor σ, and, when plotted, appears as a semicircle.
