Anomalous Pairing Currents and a Second Topological Edge Channel in Bosonic Lattices
Chitrak Bhadra, Ángel Rivas, Miguel A. Martin-Delgado
We show that bosonic pairing opens a second chiral current channel on a 2D kagome lattice, absent from any particle-conserving model. From the continuity equation, we derive both a…

Intrinsic Hamiltonian of Mean Force and Strong-Coupling Quantum Thermodynamics
Ignacio González, Sagnik Chakraborty, Ángel Rivas
We present a universal thermodynamic framework for quantum systems that may be strongly coupled to thermal environments. Unlike previous approaches, our method enables a clear defi…
