Electrically driven insulator-to-metal transition in a correlated insulator: Electronic mechanism and thermal description

Camille Didier Georges Aron

Motivated by the resistive switchings in transition-metal oxides (TMOs) induced by a voltage bias, we study the far-from-equilibrium dynamics of an electric-field-driven strongly correlated model featuring a first-order insulator-to-metal transition at equ ...

Continuous symmetry breaking in a two-dimensional Rydberg array

Andreas Martin Läuchli Herzig

Spontaneous symmetry breaking underlies much of our classification of phases of matter and their associated transitions(1-3). The nature of the underlying symmetry being broken determines many of the qualitative properties of the phase; this is illustrated ...
