Entanglement Oscillations near a Quantum Critical Point

Published Wed, Jun 17, 2020
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...

An experiment obtains a spin liquid state by squeezing a magnetic crystal

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...

Strike For Black Lives at the IIP

Published Wed, Jun 10, 2020
On June 10, 2020, the physics community stopped its activities in a strike to mark its support for Black Lives Matter movement and a call for a more decisive action towards fighting racism in all aspects of our lives, from streets to academia. The murder of George Floyd in the United States has...

IIP research advances towards understanding interactions of string theory

Published Fri, Jun 05, 2020
By Professor Thiago Fleury and Dr. Vasco Gonçalves Quantizing gravity remains an outstanding problem of modern Physics. While the procedures of the quantization of other fundamental forces of Nature are well established, the most familiar one still resists our efforts. String...
