Compressible Quantum Liquids: Field Theory Versus Holography
Speaker(s): Subir Sachdev
Abstract: The description of non-Fermi liquid metals is one of the central problems in the theory of correlated electron systems. I present a holographic theory which builds on general features of the thermal entropy density and the entanglement entropy. Remarkable connections emerge between the holographic a... read more

Strong coupling problems in condensed matter and the AdS/CFT correspondence
Speaker(s): Subir Sachdev
Abstract: I will survey some open problems posed by experiments on condensed matter systems, such as the high temperature superconductors. I will argue that their solutions require analyses of strong-coupling regimes which cannot be addressed by conventional field-theoretic means. I will describe insights dra... read more

Nodal Quasiparticles and Spin and Charge Order in the Cuprate Superconductors
Speaker(s): Subir Sachdev
Abstract: I will discuss the interplay between the fermionic nodal quasiparticles of a d-wave superconductor and the various spin and charge orders that have been observed in the cuprate superconductors. Fluctuations of a composite 'nematic' order are identified as the dominant source of inelastic scattering ... read more

Quantum criticality and black holes
Speaker(s): Subir Sachdev
Abstract: I will describe antiferromagnets and superconductors near quantum phase transitions. There is a remarkable analogy between their dynamics and the holographic description of Hawking radiation from black holes. I will show how insights from this analogy have shed light on experiments on the cuprate hi... read more
