Absence of a direct metal to Mott insulator transition for disordered interacting fermions on the Cayley tree
Ankita Chakrabarti, Nicolas Laflorencie, Bertrand Georgeot +2
Interacting fermions in the presence of disorder pose one of the most challenging problems in condensed matter physics, primarily due to the absence of accurate numerical tools. Ou…
Traveling/non-traveling phase transition and non-ergodic properties in the random transverse-field Ising model on the Cayley tree
Ankita Chakrabarti, Cyril Martins, Nicolas Laflorencie +3
We study the random transverse field Ising model on a finite Cayley tree. This enables us to probe key questions arising in other important disordered quantum systems, in particula…
Theory of Optimal Transport and the Structure of Many-Body States
S. R. Hassan, Ankita Chakrabarti, R. Shankar
There has been much work in the recent past in developing the idea of quantum geometry to characterize and understand the structure of many-particle states. For mean-field states,…
Intrinsic and extrinsic geometries of correlated many-body states
Ankita Chakrabarti, S. R. Hassan, R. Shankar
We explore two approaches to characterise the quantum geometry of the ground state of correlated fermions in terms of the distance matrix in the spectral parameter space. (a) An in…
Quantum geometry of correlated many-body states
S. R. Hassan, R. Shankar, Ankita Chakrabarti
We provide a definition of the quantum distances of correlated many fermion wave functions in terms of the expectation values of certain operators that we call exchange operators.…
