Field Theory at a Lifshitz Point
We construct the general renormalizable actions for the scalar field and gauge field at a Lifshitz point characterized by the dynamical critical exponent z. The Lorentz invariance is broken down in the UV region, but is recovered in the IR limit. Even though the theories are UV complete, the speed of light is related to the momentum by z(k/M)z−1 which can go to infinity in the UV limit for z ≥ ...
متن کاملChiral primordial gravitational waves from a Lifshitz point.
We study primordial gravitational waves produced during inflation in quantum gravity at a Lifshitz point proposed by Horava. Assuming power-counting renormalizability, foliation-preserving diffeomorphism invariance, and the condition of detailed balance, we show that primordial gravitational waves are circularly polarized due to parity violation. The chirality of primordial gravitational waves ...
متن کاملField-Induced Lifshitz Transition without Metamagnetism in CeIrIn(5).
We report high magnetic field measurements of magnetic torque, thermoelectric power, magnetization, and the de Haas-van Alphen effect in CeIrIn_{5} across 28 T, where a metamagnetic transition was suggested in previous studies. The thermoelectric power displays two maxima at 28 and 32 T. Above 28 T, a new, low de Haas-van Alphen frequency with a strongly enhanced effective mass emerges, while t...
متن کاملChiral plasmons without magnetic field.
Plasmons, the collective oscillations of interacting electrons, possess emergent properties that dramatically alter the optical response of metals. We predict the existence of a new class of plasmons-chiral Berry plasmons (CBPs)-for a wide range of 2D metallic systems including gapped Dirac materials. As we show, in these materials the interplay between Berry curvature and electron-electron int...
متن کاملDesignated magnetic field design for magnetic drug guidance in BNCT
In this paper, a local magnetic field was designed and simulated using a Helmholtz coil along with a ferromagnetic core with an appropriate geometric Structure to concentrate a magnetic flux. This field can be used for magnetic guiding of Boron-borne drugs in BNCT.
