ABSTRACT The two-dimensional (2D) magnet, a long-standing missing member in the
family of 2D functional materials, is promising for nextgeneration information technology …

Modern theories of melting of two-dimensional systems are discussed that are mainly based
on the concepts of the Berezinskii–Kosterlitz–Thouless (BKT) theory of phase transitions in …

The hexatic fluid refers to a phase in between a solid and a liquid that has short-range
positional order but quasi-long-range orientational order. In the celebrated theory of …

Abstract Two-dimensional (2D) ferromagnets with high Curie temperature have long been
the pursuit for electronic and spintronic applications. CrI 3 is a rising star of intrinsic 2D …

Adding impurities or defects destroys crystalline order. Occasionally, however, extraordinary
behaviour emerges that cannot be explained by perturbing the ordered state. One example …

Recently, detailed real-space imaging using scanning tunneling spectroscopy of the vortex
lattice in a weakly pinned a-MoGe thin film revealed that the vortex lattice melts in two steps …

Vortex matter in type-II superconductors is a model complex system belonging to the vast
ensemble of disordered elastic media. In all these systems, depinning occurs when an …

We present the first observation of dynamically modulated quantum phase transition
between two distinct charge density wave (CDW) phases in two-dimensional 2 H-NbSe 2 …

We investigate the magnetic field variation of the thermally activated flux flow resistivity, ρ
TAFF and flux flow critical current density, J c, in a weakly pinned thin film of the amorphous …

We study the vortex pinning effect on the vortex lattice structure of the rotating two-
component Bose-Einstein condensates (BECs) in the presence of impurities or disorder by …
