According to our everyday experience, macroscopic bodies out-of-equilibrium relax toward a stationary state that is largely independent of their initial conditions.
This innocent observation has baffled physicists for long when applied to the quantum realm. Indeed, as a consequence of linearity... Published Mon, Jun 15, 2020
A group at the Advanced Photon Source (APS) of the Argonne National Laboratory (USA) has obtained a state of matter closely resembling a quantum spin liquid. Such a state is characterized by a “frustration” of the electron spins – the situation in which the electrons are not able...  |  |  |  |  |  |  |
