Theory of dissipationless Nernst effects (2009)
Bergman, Doron, Oganesyan, Vadim
We develop a theory of transverse thermoelectric (Peltier) conductivity, \alpha_{xy}, in finite magnetic field -- this particular conductivity is often the most important contribution to the Nernst...
Energy transport in disordered classical spin chains (2009)
Oganesyan, Vadim, Pal, Arijeet, Huse, David A.
We present a numerical study of the diffusion of energy at high temperature in strongly disordered chains of interacting classical spins evolving deterministically. We find that quenched randomness...
Dynamical layer decoupling in a stripe-ordered, high T_c superconductor (2007)
Berg, Erez, Fradkin, Eduardo, Kim, Eun-Ah, Kivelson, Steven A., Oganesyan, Vadim, Tranquada, John, ...
In the stripe-ordered state of a strongly-correlated two-dimensional electronic system, under a set of special circumstances, the superconducting condensate, like the magnetic order, can occur at a...
Localization of interacting fermions at high temperature (2006)
Oganesyan, Vadim, Huse, David A.
We suggest that if a localized phase at nonzero temperature $T>0$ exists for strongly disordered and weakly interacting electrons, as recently argued, it will also occur when both disorder and...
Towards a statistical theory of transport by strongly-interacting lattice fermions (2005)
Mukerjee, Subroto, Oganesyan, Vadim, Huse, David
We present a study of electric transport at high temperature in a model of strongly interacting spinless fermions without disorder. We use exact diagonalization to study the statistics of the energy...
On the magnetization of two-dimensional superconductors (2005)
Oganesyan, Vadim, Huse, David A., Sondhi, S. L.
We calculate the magnetization of a two-dimensional superconductor in a perpendicular magnetic field near its Kosterlitz-Thouless transition and at lower temperatures. We find that the critical...
Mean-field theory for symmetry-breaking Fermi surface deformations on a square lattice (2005)
Yamase, Hiroyuki, Oganesyan, Vadim, Metzner, Walter
We analyze a mean-field model of electrons with pure forward scattering interactions on a square lattice which exhibits spontaneous Fermi surface symmetry breaking with a d-wave order parameter: the...
Superconductors are topologically ordered (2004)
Hansson, T. H., Oganesyan, Vadim, Sondhi, S. L.
We revisit a venerable question: what is the nature of the ordering in a superconductor? We find that the answer is properly that the superconducting state exhibits topological order in the sense of...
Formation of Electronic Nematic Phase in Interacting Systems (2004)
Khavkine, Igor, Chung, Chung-Hou, Oganesyan, Vadim, Kee, Hae-Young
We study the formation of an electronic nematic phase characterized by a broken point-group symmetry in interacting fermion systems within the weak coupling theory. As a function of interaction...
A Farewell to Liouvillians (2002)
Oganesyan, Vadim, Chalker, J. T., Sondhi, S. L.
We examine the Liouvillian approach to the quantum Hall plateau transition, as introduced recently by Sinova, Meden, and Girvin [Phys. Rev. B {\bf 62}, 2008 (2000)] and developed by Moore, Sinova and...
Competing Order in the Mixed State of High Temperature Superconductors (2002)
Kivelson, Steven A., Lee, Dung-Hai, Fradkin, Eduardo, Oganesyan, Vadim
We examine the low temperature behavior of the mixed state of a layered superconductor in the vicinity of a quantum critical point separating a pure superconducting phase from a phase in which a...
Josephson tunnelling spectroscopy of negative U centers (2001)
Oganesyan, Vadim, Kivelson, Steven, Geballe, Theodore, Moyzhes, Boris
We consider a superconductor-insulator-superconductor (SIS) junction in which the tunnelling through the insulating barrier is dominated by a localized ``negative U'' center. We show that the...
Barci, Daniel G., Fradkin, Eduardo, Kivelson, Steven A., Oganesyan, Vadim
We develop an effective low energy theory of the Quantum Hall (QH) Smectic or stripe phase of a two-dimensional electron gas in a large magnetic field in terms of its Goldstone modes and of the...
Quantum Theory of a Nematic Fermi Fluid (2001)
Oganesyan, Vadim, Kivelson, Steven, Fradkin, Eduardo
We develop a microscopic theory of the electronic nematic phase proximate to an isotropic Fermi liquid in both two and three dimensions. Explicit expressions are obtained for the small amplitude...
Moments of the ARPES spectral function of an undoped Mott insulator (2000)
We derive analytic expressions for the first three frequency moments of the single particle spectral function for one hole in a Mott insulator in terms of equilibrium spin correlation functions of...
