Influence of superohmic dissipation on a disordered quantum critical point
Thomas Vojta, J. A. Hoyos, Priyanka Mohan +1
We investigate the combined influence of quenched randomness and dissipation on a quantum critical point with O(N) order-parameter symmetry. Utilizing a strong-disorder renormaliza…
Influence of spin fluctuations near the Mott transition: a DMFT study
Serge Florens, Priyanka Mohan, C. Janani +2
Dynamics of magnetic moments near the Mott metal-insulator transition is investigated by a combined slave-rotor and Dynamical Mean-Field Theory solution of the Hubbard model with a…
Evidence for power-law Griffiths singularities in a layered Heisenberg magnet
Fawaz Hrahsheh, Hatem Barghathi, Priyanka Mohan +2
We study the ferromagnetic phase transition in a randomly layered Heisenberg model. A recent strong-disorder renormalization group approach [Phys. Rev. B 81, 144407 (2010)] predict…
Elastic properties of graphene flakes: boundary effects and lattice vibrations
S. Bera, A. Arnold, F. Evers +2
We present a calculation of the free energy, the surface free energy and the elastic constants ("Lam'e parameters" i.e, Poisson ratio, Young's modulus) of graphene flakes on the le…
An Anomalously Elastic, Intermediate Phase in Randomly Layered Superfluids, Superconductors, and Planar Magnets
Priyanka Mohan, Paul M. Goldbart, Rajesh Narayanan +2
We show that layered quenched randomness in planar magnets leads to an unusual intermediate phase between the conventional ferromagnetic low-temperature and paramagnetic high-tempe…
