His research has focused on quantum Hall-like topological phases, exotic correlated superconductors, quantum phase transitions, and topological quantum computing physics. . 14, No. In fact, the ultra-precise quantization of Hall conductivity is a salient member of this family of phenomena. 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". Berry curvature ∣ geometric tensor ∣ quantum dynamics ∣ quantum geometry ∣ quantum Hall effect In quantum mechanics the Berry phase is defined as a phase ac-cumulated by the wave function during the adiabatic evolution around a closed path in the parameter space denoted by s~.

Comments: A spin current perpendicular to the electric field is generated by either the Rashba or the Dresselhaus coupling. Experiments have discovered emergent electron phenomena from graphene moiré superlattices, including the fractal quantum Hall effect [1–3], gate-tunable Mott insulators [4,5] and superconductivity [6–11]. 246, No. Landau levels, Landau gauge and symmetric gauge. 2-3, 25 January 2012 | International Journal of Modern Physics A, Vol. 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.

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. 3, 25 January 2012 | International Journal of Modern Physics B, Vol. We use a single nitrogen-vacancy center in diamond to experimentally study a synthetic quantum Hall effect with a two-tone drive. 5, 1 Jan 1996 | Fortschritte der Physik/Progress of Physics, Vol. The Kubo formula. A common thread of the review is the semiclassical ... the spectacular quantum Hall phenomenon Thouless et al., 1982 . Here, the authors demonstrate how the Berry phase alone, without skyrmions, provides a comprehensive explanation for such a Hall response. . Integer Quantum Hall effect • basics • theories for the quantization • disorder in QHS • Berry phase in QHS • topology in QHS • effect of lattice • effect of spin and electron interaction M.C. 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. In heterostructures of 2D semiconductors, the moiré patte… 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]. It is shown here that a particle in an intense magnetic field may acquire the Berry phase and the topological features associated with this phase may be taken to be responsible for both the integrally and fractionally quantized Hall effect. Individual login 8, 1 May 1998 | Physics Letters A, Vol. In recent years, he, along with his team, has experimentally discovered topological-order in bulk solids (3D topological insulators) including the single-Dirac-cone series using spin-resolved and phase-sensitive … Berry’s phase affects both the SdH oscillations as well as the shift in the first quantum Hall effect plateau. It is shown here that a particle in an intense magnetic field may acquire the Berry phase and the topological features associated with this phase may be taken to be responsible for both the integrally and fractionally quantized Hall effect. Ultrathin SrRuO${}_{3}$ has a nontrivial Hall response that looks strikingly like a skyrmion-induced topological Hall effect. 1-2, 23 October 2007 | Il Nuovo Cimento B Series 11, Vol. or One is the conventional quantum Hall effect, characteristic of two-dimensional semiconductor systems, and the other is its relativistic counterpart observed in graphene, where charge carriers mimic Dirac fermions characterized by Berry's phase π, which results in shifted positions of the Hall plateaus. Institutional login The classical Hall effect, the integer quantum Hall effect and the fractional quantum Hall effect. The vertical axis is the strength of the magnetic field and the horizontal axis is the chemical potential, which fixes the electron density. Disorder and Gauge Invariance. In Ideas of Quantum Chemistry, 2007. Intrinsic versus extrinsic contributions 1974 2. 6, 1 Oct 2005 | Physics Letters A, Vol. 7.2 Anomalous Hall effect due to the Berry phase in a textured ferromagnet . Subsequently, Berry has been honored with numerous scientific and mathematical awards, as well as being knighted by Queen Elizabeth in 1996. . That is, a quantized Hall effect that does not require an external magnetic field. 01, 1 Dec 1997 | Physics Letters A, Vol. We now sail into the quantum world, which features anholonomic effects associated with the intrinsic curvatures of certain abstract spaces. When considering accurate quantum dynamics calculations (point 3 on p. 770) we encounter the problem of what is called Berry phase. 1-2, 15 August 1998 | Physical Review B, Vol. A short introduction to the Berry phase will be given first. They are known in mathematics as the first Chern numbers and are closely related to Berry's phase. This remarkable quantum effect was first described clearly by Michael Berry, a mathematical physicist at the University of Bristol, in a paper in 1984 [1], and it became known as the “Berry phase”. Quasiperiodically driven quantum systems are predicted to exhibit quantized topological properties, in analogy with the quantized transport properties of topological insulators. 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. 13, No. If you have any questions about IOP ebooks e-mail us at ebooks@ioppublishing.org.
