Holographic charge density waves (2013)
Journal Article
Donos, A., & Gauntlett, J. P. (2013). Holographic charge density waves. Physical Review D, 87(12), https://doi.org/10.1103/physrevd.87.126008

We show that strongly coupled holographic matter at finite charge density can exhibit charge density wave phases which spontaneously break translation invariance while preserving time-reversal and parity invariance. We show that such phases are possi... Read More about Holographic charge density waves.

Striped phases from holography (2013)
Journal Article
Donos, A. (2013). Striped phases from holography. Journal of High Energy Physics, 2013(5), Article 59. https://doi.org/10.1007/jhep05%282013%29059

We discuss new types of second order phase transitions in holography by constructing striped black holes in D = 4 with AdS4 asymptotics. In the context of AdS/CFT, they provide the gravity duals to field theory phases in which translational symmetry... Read More about Striped phases from holography.

Competing orders in M-theory: superfluids, stripes and metamagnetism (2013)
Journal Article
Donos, A., Gauntlett, J. P., Sonner, J., & Withers, B. (2013). Competing orders in M-theory: superfluids, stripes and metamagnetism. Journal of High Energy Physics, 2013(3), Article 108. https://doi.org/10.1007/jhep03%282013%29108

We analyse the infinite class of d = 3 CFTs dual to skew-whiffed AdS 4 × SE 7 solutions of D = 11 supergravity at finite temperature and charge density and in the presence of a magnetic field. We construct black hole solutions corresponding to the un... Read More about Competing orders in M-theory: superfluids, stripes and metamagnetism.

Semi-local quantum criticality in string/M-theory (2013)
Journal Article
Donos, A., Gauntlett, J. P., & Pantelidou, C. (2013). Semi-local quantum criticality in string/M-theory. Journal of High Energy Physics, 2013(3), Article 103. https://doi.org/10.1007/jhep03%282013%29103

Semi-local quantum critical behaviour in D − 1 spacetime dimensions can be holographically described by metrics that are conformal to AdS 2 ×R D−2 , with the conformal factor characterised by a parameter η. We analyse such “η-geometries” in a top-dow... Read More about Semi-local quantum criticality in string/M-theory.
