Effective Hamiltonian for Ga_{1-x}Mn_xAs in the Dilute Limit
Gregory A. Fiete, Gergely Zarand, Kedar Damle
We derive an effective Hamiltonian for in the dilute limit, where can be described in terms of spin …
A neutron scattering study of two-magnon states in the quantum magnet copper nitrate
D. A. Tennant, C. Broholm, D. H. Reich +7
We report measurements of the two-magnon states in a dimerized antiferromagnetic chain material, copper nitrate (Cu(NO3)2*2.5D2O). Using inelastic neutron scattering we have measur…
Permutation-Symmetric Multicritical Points in Random Antiferromagnetic Spin Chains
Kedar Damle, David A. Huse
The low-energy properties of a system at a critical point may have additional symmetries not present in the microscopic Hamiltonian. This letter presents the theory of a class of m…
Translational Symmetry Breaking in the Superconducting State of the Cuprates: Analysis of the Quasiparticle Density of States
Daniel Podolsky, Eugene Demler, Kedar Damle +1
Motivated by the recent STM experiments of J.E. Hoffman et.al. and C. Howald et.al., we study the effects of weak translational symmetry breaking on the quasiparticle spectrum of a…
Griffiths Effects in Random Heisenberg Antiferromagnetic S=1 Chains
Kedar Damle
I consider the effects of enforced dimerization on random Heisenberg antiferromagnetic S=1 chains. I argue for the existence of novel Griffiths phases characterized by {\em two ind…
