Quantum criticality beyond the Landau-Ginzburg-Wilson paradigm
T. Senthil, Leon Balents, Subir Sachdev +2
We present the critical theory of a number of zero temperature phase transitions of quantum antiferromagnets and interacting boson systems in two dimensions. The most important exa…
Quench dynamics across quantum critical points
K. Sengupta, Stephen Powell, Subir Sachdev
We study the quantum dynamics of a number of model systems as their coupling constants are changed rapidly across a quantum critical point. The primary motivation is provided by th…
"Deconfined" quantum critical points
T. Senthil, Ashvin Vishwanath, Leon Balents +2
The theory of second order phase transitions is one of the foundations of modern statistical mechanics and condensed matter theory. A central concept is the observable `order param…
Competing density-wave orders in a one-dimensional hard-boson model
Paul Fendley, K. Sengupta, Subir Sachdev
We describe the zero-temperature phase diagram of a model of bosons, occupying sites of a linear chain, which obey a hard-exclusion constraint: any two nearest-neighbor sites may h…
Competing orders in thermally fluctuating superconductors in two dimensions
Subir Sachdev, Eugene Demler
We extend recent low temperature analyses of competing orders in the cuprate superconductors to the pseudogap regime where all orders are fluctuating. A universal continuum limit o…
Weak magnetism and non-Fermi liquids near heavy-fermion critical points
T. Senthil, Matthias Vojta, Subir Sachdev
This paper is concerned with the weak-moment magnetism in heavy-fermion materials and its relation to the non-Fermi liquid physics observed near the transition to the Fermi liquid.…
