Transport properties of the classical Toda chain: effect of a pinning potential
Abhishek Dhar, Aritra Kundu, Joel L. Lebowitz +1
We consider energy transport in the classical Toda chain in the presence of an additional pinning potential. The pinning potential is expected to destroy the integrability of the s…
Consequences of integrability breaking in quench dynamics of pairing Hamiltonians
Jasen A. Scaramazza, Pietro Smacchia, Emil A. Yuzbashyan
We study the collisionless dynamics of two classes of nonintegrable pairing models. One is a BCS model with separable energy-dependent interactions, the other - a 2D topological su…
Ballistic transport in the classical Toda chain with harmonic pinning
Joel L. Lebowitz, Jasen A. Scaramazza
We investigate, via numerical simulation, heat transport in the nonequilibrium stationary state (NESS) of the 1D classical Toda chain with an additional pinning potential, which de…
A note on Lee-Yang zeros in the negative half-plane
Joel L. Lebowitz, Jasen A. Scaramazza
We obtain lower bounds on the inverse compressibility of systems whose Lee-Yang zeros of the grand-canonical partition function lie in the left half of the complex fugacity plane.…
Rotationally invariant ensembles of integrable matrices
Emil A. Yuzbashyan, B. Sriram Shastry, Jasen A. Scaramazza
We construct ensembles of random integrable matrices with any prescribed number of nontrivial integrals and formulate integrable matrix theory (IMT) -- a counterpart of random matr…
Competing Orders in a Dipolar Bose-Fermi Mixture on a Square Optical Lattice: Mean-Field Perspective
Jasen A. Scaramazza, Ben Kain, Hong Y. Ling
We consider a mixture of a two-component Fermi gas and a single-component dipolar Bose gas in a square optical lattice and reduce it into an effective Fermi system where the Fermi-…
