Frustrating the Kondo effect might hold the key to the Mott MIT in ∞ dimensions: our new work just got published at New Journal of Physics!
We provide a Hamiltonian-based explanation of the DMFT-based phenomenology of the infinite dimensional Hubbard model, obtaining novel insights on the Mott MI...
Can entanglement scaling lead to universality across various metals or insulators?
In a work that appeared recently at New Journal of Physics, Patra et al classify various emergent phases of matter in terms of entanglement measures.
A simple graph-theoretic construct outlines much of the physics of the multichannel Kondo effect!
In this work, we elucidate the importance of ground-state degeneracy and frustration in determining the physics of the multichannel Kondo model.
Can space emerge from quantum mechanics? We demonstrate this in a simple model of fermions!
We show the emergence of an additional dimension arising out of the scaling of multipartite entanglement upon applying RG transformations on 2D noninteractin...
Our recent work on entanglement of topologically ordered systems has been published in Phys. Rev. A
In this work, we investigate the nature of the general (N-)partite information and quantum correlation of a topologically ordered ground state.
Our work on the entanglement of the doped 2D Hubbard model got published in J. Phys. Cond. Mat.
In this work, we cast the renormalization group flows of the 2D Hubbard model in terms of entanglement evolution, revealing holographic features along the way.
Our work on the single-channel Kondo problem has been published in Phys. Rev. B
We analyze the single-channel Kondo model using the recently developed unitary renormalization-group (URG) method and obtain a comprehensive understanding of...
Our work on the Cooper pair insulator has been published in Phys. Rev. B
We present a microscopic derivation of the Cooper-pair insulator (CPI), a topologically ordered counterpart of the (s-)wave superconductor.
