Perturbative non-Fermi liquids from dimensional regularization
, 2013 We devise a dimensional regularization scheme for quantum field theories with Fermi surface to study scaling behaviour of non-Fermi liquid states in a controlled approximation.

Berry Curvature, Triangle Anomalies, and the Chiral Magnetic Effect in Fermi Liquids
, 2012 In a three-dimensional Fermi liquid, quasiparticles near the Fermi surface may possess a Berry curvature. We show that if the Berry curvature has a nonvanishing flux through the Fermi surface, the particle number associated with this Fermi surface has a ...

The change of Fermi surface topology in Bi2Sr2CaCu2O8 with doping [PDF]
, 2005 We report the observation of a change in Fermi surface topology of Bi2Sr2CaCu2O8 with doping. By collecting high statistics ARPES data from moderately and highly overdoped samples and dividing the data by the Fermi function, we answer a long standing ...

Evolution of the low-temperature Fermi surface of superconducting FeSe1−xSx across a nematic phase transition [PDF]
npj Quantum Materials, 2016 The existence of a nematic phase transition in iron-chalcogenide superconductors poses an intriguing question about its impact on superconductivity.

Advanced Functional Materials, EarlyView.The plasma edge of transparent conducting oxide SrNbO3 shifts from ∼2 eV in the visible range to 1.37 eV in the near‐infrared region by off‐stoichiometry using the vacancy sites as quasi‐substitutional virtual elements. This work advances the stoichiometry engineering of perovskite oxides using oxide molecular beam epitaxy, allowing synthesis beyond ...

Deformation of anisotropic Fermi surfaces due to electron-electron interactions
, 2006 We analyze the deformations of the Fermi surface induced by electron-electron interactions in anisotropic two dimensional systems. We use perturbation theory to treat, on the same footing, the regular and singular regions of the Fermi surface.

Quantum oscillations in Kondo Insulator SmB$_6$ [PDF]
, 2013 In Kondo insulator samarium hexaboride SmB$_6$, strong correlation and band hybridization lead to an insulating gap and a diverging resistance at low temperature. The resistance divergence ends at about 5 Kelvin, a behavior recently demonstrated to arise

Gyrotropic Magnetic Effect and the Magnetic Moment on the Fermi Surface. [PDF]
Physical Review Letters, 2015 The current density j^{B} induced in a clean metal by a slowly-varying magnetic field B is formulated as the low-frequency limit of natural optical activity, or natural gyrotropy.

Photoswitchable Conductive Metal–Organic Frameworks
Advanced Functional Materials, EarlyView.A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.
