Shape dependence of two-cylinder Renyi entropies for free bosons on a lattice
Leilee Chojnacki, Caleb Q. Cook, Denis Dalidovich +4
Universal scaling terms occurring in Renyi entanglement entropies have the potential to bring new understanding to quantum critical points in free and interacting systems. Quantita…
Perturbative non-Fermi liquids from dimensional regularization
Denis Dalidovich, Sung-Sik Lee
We devise a dimensional regularization scheme for quantum field theories with Fermi surface to study scaling behaviour of non-Fermi liquid states in a controlled approximation. Sta…
Schwinger-Keldysh approach to out of equilibrium dynamics of the Bose Hubbard model with time varying hopping
Malcolm P. Kennett, Denis Dalidovich
We study the real time dynamics of the Bose Hubbard model in the presence of time-dependent hopping allowing for a finite temperature initial state. We use the Schwinger-Keldysh te…
Superfluid density near the critical temperature in the presence of random planar defects
D. Dalidovich, A. J. Berlinsky, C. Kallin
The superfluid density near the superconducting transition is investigated in the presence of spatial inhomogeneity in the critical temperature. Disorder is accounted for by means…
Bose Hubbard model in the presence of Ohmic dissipation
Denis Dalidovich, Malcolm P. Kennett
We study the zero temperature mean-field phase diagram of the Bose-Hubbard model in the presence of local coupling between the bosons and an external bath. We consider a coupling t…
Spin Structure Factor of the Frustrated Quantum Magnet Cs_2CuCl_4
Denis Dalidovich, Rastko Sknepnek, A. John Berlinsky +2
The ground state properties and neutron structure factor for the two-dimensional antiferromagnet on the triangular lattice, with uni-directional anisotropy in the nearest-neighbor…
