Nernst effect and diamagnetism in phase fluctuating superconductors
Daniel Podolsky, Srinivas Raghu, Ashvin Vishwanath
When a superconductor is warmed above its critical temperature , long range order is destroyed by fluctuations in the order parameter. These fluctuations can be probed by meas…
Spin Liquid States on the Triangular and Kagome Lattices: A Projective Symmetry Group Analysis of Schwinger Boson States
Fa Wang, Ashvin Vishwanath
A symmetry based analysis (Projective Symmetry Group) is used to study spin liquid phases on the triangular and Kagomé lattices in the Schwinger boson framework. A maximum of eight…
Theory of helical spin crystals: phases, textures and properties
B. Binz, A. Vishwanath
Motivated by recent experiments on the itinerant helimagnet MnSi, we study general properties of helical spin crystals - magnetic structures obtained by superposing distinct spin s…
Current fluctuations near to the 2D superconductor-insulator quantum critical point
A. G. Green, J. E. Moore, S. L. Sondhi +1
Systems near to quantum critical points show universal scaling in their response functions. We consider whether this scaling is reflected in their fluctuations; namely in current-n…
