DOI: 10.1103/physrevb.101.035116
Abstract: The study of (quantum) phase transitions in heavy-fermion compounds relies on a detailed understanding of the microscopic control parameters that induce them. While the influence of external pressure is rather straight forward, atomic substitutions are… read more here.

DOI: 10.1103/physrevb.103.104506
Abstract: I determine the intrinsic Hamiltonian of the relative motion of the constituent fermions of bosonic composites in superfluid fermion systems, assuming the effective fermion-fermion potential to be a sum of separable terms. The derivation is… read more here.

DOI: 10.1103/physrevb.98.235405
Abstract: Open fermion systems with energy-independent bilinear coupling to a fermionic environment have been shown to obey a general duality relation [J. Schulenborg, Phys. Rev. B 93, 081411 (2016)2469-995010.1103/PhysRevB.93.081411] which allows for a drastic simplification of… read more here.
