  • quantum Electric dipole liquid on a triangular lattice
    Nature Communications, 2016
    Co-Authors: Shi Peng Shen, Jia Chuan Wu, Jun Da Song, Yi Sheng Chai, Da Shan Shang, James F Scott, Shou-guo Wang, Yi Feng Yang
    Abstract:

    Geometric frustration and quantum fluctuations may prohibit the formation of long-range ordering even at the lowest temperature, and therefore liquid-like ground states could be expected. A good example is the quantum spin liquid in frustrated magnets. Geometric frustration and quantum fluctuations can happen beyond magnetic systems. Here we propose that quantum Electric-dipole liquids, analogues of quantum spin liquids, could emerge in frustrated diElectrics where antiferroElectrically coupled Electric Dipoles reside on a triangular lattice. The quantum paraElectric hexaferrite BaFe12O19 with geometric frustration represents a promising candidate for the proposed Electric-dipole liquid. We present a series of experimental lines of evidence, including diElectric permittivity, heat capacity and thermal conductivity measured down to 66 mK, to reveal the existence of an unusual liquid-like quantum phase in BaFe12O19, characterized by itinerant low-energy excitations with a small gap. The possible quantum liquids of Electric Dipoles in frustrated diElectrics open up a fresh playground for fundamental physics.

  • Quantum Electric-dipole liquid on a triangular lattice
    Nature Communications, 2016

    Abstract:

    Quantum mechanical fluctuations and geometric frustrations prohibit the formation of long-range ordering even at the lowest temperatures, and therefore a liquid-like ground state could be expected. A good example of such is the quantum spin liquid in frustrated antiferromagnets that represents an exotic phase of matter and has drawn enormous attention from both theoretical and experimental aspects. Geometric frustrations and quantum fluctuations can also happen in Electric systems. Here we propose that a quantum Electric-dipole liquid, which is an Electric analog to the spin liquid, could emerge in a frustrated Electric system where antiferroElectrically coupled small Electric Dipoles reside on a triangular lattice. We present a series of experimental evidences, including diElectric permittivity, heat capacity, and thermal conductivity measured down to 66 mK, to identify such a liquid-like ground state in the hexagonal ferrite BaFe12O19 where Ising-type small Electric Dipoles originated from the off-center displacement of Fe3+ ion in the FeO5 bipyramids constitute a two-dimensional triangular lattice. The quantum liquid state of frustrated Electric Dipoles not only opens up a fresh playground for sophisticated quantum physics, but also has a promise for applications in high-density data storage and quantum computation, as that anticipated for quantum spin liquids.

  • Electric Dipoles perpendicular to a stick slip plane
    Physics of the Earth and Planetary Interiors, 2006
    Co-Authors: Akihiro Takeuchi, Hiroyuki Nagahama
    Abstract:

    Abstract Stick-slip tests of pre-cut quartz pegmatite cylinders under tri-axial compression were conducted with a solenoid or toroidal coil near or surrounding the stick-slip plane. The solenoid coil detected damped oscillating signals during stick-slip events. The toroidal coil detected similar oscillations but on an exponential decay. The damped oscillating component is the induced electromotive force (emf) voltage due to piezoElectric polarizations of individual quartz crystals or due to the Earth's magnetostatic field when the coils vibrate. The exponentially decaying component is the induced emf voltage due to Electric Dipoles approximately perpendicular to the stick-slip plane. These perpendicular Dipoles can be explained by the formation of surface charges on separate asperities. The exponential decay of the perpendicular Dipoles is due to exponential diffusion and recombination of the separate charges. Electric Dipoles on separated asperities may also exist on the geophysical scale: on fault planes during faulting.
