Analogue Gravity Models From Conformal Rescaling
, 2020 Analogue gravity is based on a mathematical identity between quantum field theory in curved space-time and the propagation of perturbations in certain condensed matter systems.

Drag suppression in anomalous chiral media [PDF]
, 2016 We study a heavy impurity moving longitudinal with the direction of an external magnetic field in an anomalous chiral medium. Such system would carry a non-dissipative current of chiral magnetic effect associated with the anomaly.

Nonlinearity-assisted quantum tunneling in a matter-wave interferometer
, 2007 We investigate the {\em nonlinearity-assisted quantum tunneling} and formation of nonlinear collective excitations in a matter-wave interferometer, which is realised by the adiabatic transformation of a double-well potential into a single-well harmonic ...

Sensitivity of Hawking radiation to superluminal dispersion relations [PDF]
, 2009 We analyze the Hawking radiation process due to collapsing configurations in the presence of superluminal modifications of the dispersion relation. With such superluminal dispersion relations, the horizon effectively becomes a frequency-dependent concept.

Status of Horava gravity: A personal perspective
, 2011 Horava gravity is a relatively recent (Jan 2009) idea in theoretical physics for trying to develop a quantum field theory of gravity. It is not a string theory, nor loop quantum gravity, but is instead a traditional quantum field theory that breaks ...

, 2016 In this talk I summarize a novel framework that unifies the stunning success of MOND on galactic scales with the triumph of the $\Lambda$CDM model on cosmological scales. This is achieved through the rich and well-studied physics of superfluidity.

Hydrodynamic fluctuations and the minimum shear viscosity of the dilute Fermi gas at unitarity
, 2013 We study hydrodynamic fluctuations in a non-relativistic fluid. We show that in three dimensions fluctuations lead to a minimum in the shear viscosity to entropy density ratio $\eta/s$ as a function of the temperature.

Fermionic Superfluid from a Bilayer Band Insulator in an Optical Lattice
, 2012 We propose a model to realize a fermionic superfluid state in an optical lattice circumventing the cooling problem. Our proposal exploits the idea of tuning the interaction in a characteristically low entropy state, a band-insulator in an optical bilayer

Topological superconductors as nonrelativistic limits of Jackiw-Rossi and Jackiw-Rebbi models
, 2010 We argue that the nonrelativistic Hamiltonian of p_x+ip_y superconductor in two dimensions can be derived from the relativistic Jackiw-Rossi model by taking the limit of large Zeeman magnetic field and chemical potential.
