We study the electron-phonon coupling in twisted bilayer graphene (TBG), which was
recently experimentally observed to exhibit superconductivity around the magic twist angle …

NATURE abounds with phase transitions. The boiling and freezing of water are everyday
examples of phase transitions, as are more exotic processes such as superconductivity and …

Studies of the electromagnetic response of various classes of correlated electron materials
including transition-metal oxides, organic and molecular conductors, intermetallic …

A quantum system can undergo a continuous phase transition at the absolute zero of
temperature as some parameter entering its Hamiltonian is varied. These transitions are …

In recent years, quantum phase transitions have attracted the interest of both theorists and
experimentalists in condensed matter physics. These transitions, which are accessed at zero …

We find experimentally that the optical sheet conductance of graphite per graphene layer is
very close to (π/2) e 2/h, which is the theoretically expected value of dynamical conductance …

The interacting disordered electron problem is reviewed with emphasis on the quantum
phase transitions that occur in a model system and on the field-theoretic methods used to …

The field of phase transitions and critical phenomena continues to be active in research,
producing a steady stream of interesting and fruitful results. It has moved into a central place …
