Scale invariance of the polaron energy at the Mott-superfluid critical point
Matija Čufar, Ragheed Alhyder, C. J. Bradly +4
Continuous quantum phase transitions are characterized by an order parameter and correlation functions that are often challenging to access experimentally or in direct numerical si…
Bound excited states of Fröhlich polarons in one dimension
Jamie Taylor, Matija Čufar, David Mitrouskas +3
The one-dimensional Fröhlich model describing the motion of a single electron interacting with optical phonons is a paradigmatic model of quantum many-body physics. We predict the…
Lattice Bose polarons at strong coupling and quantum criticality
Ragheed Alhyder, Victor E. Colussi, Matija Čufar +3
We develop a new theoretical framework for exploring a mobile impurity interacting strongly with a highly correlated bath of bosons in the quantum critical regime of a Mott insulat…
Effective theory for strongly attractive one-dimensional fermions
Timothy G. Backert, Fabian Brauneis, Matija Čufar +3
We study a one-dimensional system of two-component fermions in the limit of strong attractive particle-particle interactions. First, we analyze scattering in the corresponding few-…
Self-consistent calculation of the coupling constant in the Gross-Pitaevskii equation
A. Yu. Cherny, J. Brand
A method is proposed for a self-consistent evaluation of the coupling constant in the Gross-Pitaevskii equation without involving a pseudopotential replacement. A renormalization o…
