CFT Complexity and Penalty Factors
Stefano Baiguera, Nicolas Chagnet, Shira Chapman +1
Quantum complexity of conformal field theory (CFT) states has recently gained significant attention, both as a diagnostic tool in condensed matter systems and in connection with ho…
Natural anomalous cyclotron response in a hydrodynamic local quantum critical metal in a periodic potential
Nicolas Chagnet, Sam Arend, Floris Balm +3
We study DC magnetotransport in a quantum critical metal in the presence of a lattice. In the regime where the transport is hydrodynamical the interplay of the Lorentz force and th…
Hydrodynamics of a relativistic charged fluid in the presence of a periodically modulated chemical potential
Nicolas Chagnet, Koenraad Schalm
We study charged hydrodynamics in a periodic lattice background. Fluctuations are Bloch waves rather than single momentum Fourier modes. At boundaries of the unit cell where hydrod…
T-linear resistivity, optical conductivity and Planckian transport for a holographic local quantum critical metal in a periodic potential
Floris Balm, Nicolas Chagnet, Sam Arend +9
High cuprate strange metals are noted for a DC-resistivity that scales linearly with from the onset of superconductivity to the crystal melting temperature, indicative of…
Quantization and variational problem of the Gubser-Rocha Einstein-Maxwell-Dilaton model, conformal and non-conformal deformations, and its proper thermodynamics
Nicolas Chagnet, Floris Balm, Koenraad Schalm
We show that the strongly coupled field theory holographically dual to the Gubser-Rocha anti-de-Sitter Einstein-Maxwell-Dilaton theory describes not a single non-trivial AdS IR…
Emerging Fermi liquids from regulated Quantum Electron Stars
Nicolas Chagnet, Vladan Djukić, Mihailo Čubrović +1
We construct a fully quantum zero-temperature electron star in a soft-wall regulated anti-de-Sitter Einstein-Maxwell-Dirac theory that is thermodynamically stable compared to the R…
Complexity for Conformal Field Theories in General Dimensions
Nicolas Chagnet, Shira Chapman, Jan de Boer +1
We study circuit complexity for conformal field theory states in arbitrary dimensions. Our circuits start from a primary state and move along a unitary representation of the Lorent…
