In monolayer graphene, the Berry’s phase contributes to the π - shift in the SdH oscillations and a half-integer shift in the Hall conductivity plateau as the Fermi energy ( E F ) crosses the n = 0 Landau level. 20 7.3 Interference effects due to the Berry phase in an Aharonov-Bohm ring . The chapter is subdivided as follows. A brief summary of necessary background is given and a detailed discussion of the Berry phase effect in a variety of solid-state applications. Subsequently, Berry has been honored with numerous scientific and mathematical awards, as well as being knighted by Queen Elizabeth in 1996. This will aid in understanding the mechanism behind the topo - Anholonomic processes and the topological invariants connected with them turn out to be an inherent aspect of the quantum world. topological Hall effect in the 2DEG systems mentioned above and we will try to improve our understanding of the effect in different regimes by means of numerical investigations.

This review concerns applications of the Berry phase concept in solid-state physics. 345, No. 26, 21 November 2011 | Modern Physics Letters B, Vol. In van der Waals layered structures, the creation of long-period moiré patterns (via a small lattice mismatch between the layers) has become a powerful method for engineering superlattice electronic, optical and topological properties. . 10, 21 November 2011 | Modern Physics Letters B, Vol. . In short, the quantum anomalous Hall effect (QAHE) is the quantized version of the regular anomalous Hall effect (AHE). 21 May 2008 | Physica Scripta, Vol. 2-3, 25 January 2012 | International Journal of Modern Physics A, Vol. Published August 2016 In sharp contrast, we here discuss that the PHE also occurs in nonmagnetic band insulators subject to the magnetic field. 58, No. In quantum mechanics the Berry phase is defined as a phase accumulated by the wave function during the adiabatic evolution around a closed path in the parameter space denoted by . This remarkable quantum effect was first described clearly by Michael Berry, a mathematical physicist at the University of Bristol, in a paper in 1984 , and it became known as the "Berry phase".

The vertical axis is the strength of the magnetic field and the horizontal axis is the chemical potential, which fixes the electron density. "Berry's phase is a ubiquitous and fundamental notion in quantum physics," says Murakawa. Berry phase in quantum mechanics. . His research has focused on quantum Hall-like topological phases, exotic correlated superconductors, quantum phase transitions, and topological quantum computing physics. The phase obtained has a contribution from the state's time evolution and another from the variation of the eigenstate with the changing Hamiltonian. 28, 25 January 2012 | International Journal of Modern Physics A, Vol. 14, No. A short introduction to the Berry phase will be given first. PHE is known in (para)magnetic compounds, where the magnetic moments and spin-orbit interaction play an essential role. . 12, No. 77, No. Subsequently, Berry has been honored with numerous scientific and mathematical awards, as well as being knighted by Queen Elizabeth in 1996. We use a single nitrogen-vacancy center in diamond to experimentally study a synthetic quantum Hall effect with a two-tone drive. 4-6, 1 May 2000 | Physics Letters A, Vol. Please check your inbox for the reset password link that is only valid for 24 hours.

One is the conventional quantum Hall effect, characteristic of two-dimensional semiconductor systems, and the other is its relativistic counterpart recently observed in graphene, where charge carriers mimic Dirac fermions characterized by Berry's phase pi, which results in a shifted positions of Hall plateaus. conventional quantum Hall effect, characteristic of two-dimensional semiconductor systems [1,2], and the other is its relativistic counterpart recently observed in graphene, where charge carriers mimic Dirac fermions characterized by Berry’s phase S, which results in a shifted positions of Hall plateaus [3-9]. Comments: Here, the authors demonstrate how the Berry phase alone, without skyrmions, provides a comprehensive explanation for such a Hall response. 15, No. . They are known in mathematics as the first Chern numbers and are closely related to Berry's phase.
