DOI: 10.1038/s41467-017-00167-6
Abstract: A unified theory of quantum critical points beyond the conventional Landau–Ginzburg–Wilson paradigm remains unknown. According to Landau cubic criterion, phase transitions should be first-order when cubic terms of order parameters are allowed by symmetry in… read more here.

DOI: 10.1088/1751-8121/ab370b
Abstract: We consider the Grover walk model on a connected finite graph with two infinite length tails and we set an $\ell^\infty$-infinite external source from one of the tails as the initial state. We show that… read more here.

DOI: 10.1103/physrevb.99.224420
Abstract: Much of what we know about quantum criticality comes from studies of quantum phase transitions between paramagnetic and magnetically ordered phases. These are usually driven by magnetic field or pressure. Here, the authors report that… read more here.

Abstract: Synchronization is a widespread phenomenon in science and technology. Here, we study noise-induced synchronization in a quantum spin chain subjected to local Gaussian white noise. We demonstrate stable (anti)synchronization between the endpoint magnetizations of a… read more here.
