Ultrafast nonvolatile memory

We exposed only one patent, but the members of the program group reported three patents in the previous year .The invention refers to an ultrafast quench based nonvolatile bistable device, which changes its physical properties after exposure to a temporally short external perturbation by laser or electrical pulse. This change can be detected as change of optical properties of the material or electrical resistance. The properties can be reverted back to their original state by the application of a heating pulse.

Ultrafast switching to a stable hidden quantum state in an electronic crystal

We just highlight one of the lectures. In 2015, members of the program group were invited as lecturers at numerous conferences, universities and other institutions. Hidden states are distinct from thermodynamic phases of matter, and cannot be reached under ergodic conditions. We present an example where a hidden many body quantum state is reached under non-equilibrium conditions by laser excitation of an electronic crystal. The mechanism relies on the separation of the fundamental degrees of freedom under nonequilibrium conditions.

Ultrafast carrier localisation in the pseudogap state of cuprate superconductors

In this article we have studied nonequilibrium phase transition into the pseudogap state. Th three-pulse experiments have revealed short correlation range of the dynamical state and individual character of the quasiparticle relaxation. Energy required for nonthermal destruction of the pseudogap scales linearly with the gap. This is explained with the model which accounts for subgap phonons generation.

World record from the Jožef Stefan Institute

One of the important interviews is highlighted; the problem of modern computers are speed and temperature. Members of the program group under the leadership of dr. Dragan Mihailović managed to identified improvements that could enhance the performance of computers.

Nonequilibrium phenomena in complex matter: new observations and new theories. December 13. - 16., 2015, Krvavec, Slovenia

Co-organization of scientific meeting; The scope of the meeting is to focus on new approaches to theory of ultrafast phenomena in correlated electronic systems as well as related experimental observation. This covers fundamental problems of hot carrier relaxation in strange metals, collective phenomena and quasi-particle relaxation in superconductors, charge and spin density way systems, excitonic and Mott insulators and related materials.
