Vortices in spin-orbit-coupled Bose-Einstein condensates

- J. Radić, Tigran A. Sedrakyan, I. Spielman, V. Galitski
- Physics
- 21 August 2011

Realistic methods to create vortices in spin-orbit-coupled Bose-Einstein condensates are discussed. It is shown that, contrary to common intuition, rotation of the trap containing a spin-orbit… Expand

Absence of Bose condensation on lattices with moat bands

- Tigran A. Sedrakyan, L. Glazman, A. Kamenev
- Physics
- 28 March 2013

We study hard-core bosons on a class of frustrated lattices with the lowest Bloch band having a degenerate minimum along a closed contour, the moat, in the reciprocal space. We show that at small… Expand

Boundary Wess-Zumino-Novikov-Witten model from the pairing Hamiltonian

- Tigran A. Sedrakyan, V. Galitski
- Physics
- 4 May 2010

Correlation functions of primary fields in the Wess-Zumino-Novikov-Witten (WZNW) model are known to satisfy a system of Knizhnik-Zamolodchikov (KZ) equations, which involve constants of motion of the… Expand

Pseudogap in underdoped cuprates and spin-density-wave fluctuations

- Tigran A. Sedrakyan, A. Chubukov
- Physics
- 19 February 2010

We analyze fermionic spectral function in the spin-density-wave (SDW) phase of quasi-two-dimensional (quasi-2D) cuprates at small but finite $T$. We use a nonperturbative approach and sum up infinite… Expand

Composite fermion state of spin-orbit coupled bosons

- Tigran A. Sedrakyan, A. Kamenev, L. Glazman
- Physics
- 30 August 2012

Department of Physics, Yale University, New Haven, Connecticut 06520, USA(Dated: August 31, 2012)We consider spinor Bose gas with the isotropic Rashba spin-orbit coupling in 2D. We argue that atlow… Expand

Spontaneous formation of a nonuniform chiral spin liquid in a moat-band lattice.

Proposed signature of Anderson localization and correlation-induced delocalization in an N-leg optical lattice

- Tigran A. Sedrakyan, J. Kestner, S. Sarma
- Physics
- 15 September 2011

We propose a realization of the one-dimensional random dimer model and certain N-leg generalizations using cold atoms in an optical lattice. We show that these models exhibit multiple delocalization… Expand

Fermionization of bosons in a flat band

- S. Maiti, Tigran A. Sedrakyan
- PhysicsPhysical Review B
- 1 October 2018

Strongly interacting bosons that live in a lattice with degeneracy in its lowest energy band experience frustration that can prevent the formation of a Bose-Einstein condensate. Such systems form an… Expand

Topological spin ordering via Chern-Simons superconductivity

- Tigran A. Sedrakyan, V. Galitski, A. Kamenev
- Physics
- 27 June 2016

We use the Chern-Simons (CS) fermion representation of s =1/2 spin operators to construct topological, long-range magnetically ordered states of interacting two-dimensional (2D) quantum spin models.… Expand
