Green's functions of quasi-one-dimensional layered systems and their application to Josephson junctions
Kiryl Piasotski, Mikhail Pletyukhov, Alexander Shnirman
We develop Green's function formalism to describe continuous multi-layered quasi-one-dimensional setups described by piece-wise constant single-particle Hamiltonians. The Hamiltoni…
Universal properties of boundary and interface charges in multichannel one-dimensional models without symmetry constraints
Niclas Müller, Kiryl Piasotski, Dante M. Kennes +2
The boundary charge that accumulates at the edge of a one-dimensional single-channel insulator is known to possess the universal property, that its change under a lattice shift tow…
Universality of Abelian and non-Abelian Wannier functions in one dimension
Kiryl Piasotski, Mikhail Pletyukhov, Clara S. Weber +3
Within a Dirac model in dimensions, a prototypical model to describe low-energy physics for a wide class of lattice models, we propose a field-theoretical version for the rep…
Diagrammatic Approach to Scattering of Multi-Photon States in Waveguide QED
Kiryl Piasotski, Mikhail Pletyukhov
We give an exposure to diagrammatic techniques in waveguide QED systems. A particular emphasis is placed on the systems with delayed coherent quantum feedback. Specifically, we sho…
Universality of Boundary Charge Fluctuations
Clara S. Weber, Kiryl Piasotski, Mikhail Pletyukhov +4
We establish the quantum fluctuations of the charge accumulated at the boundary of an insulator as an integral tool to characterize phase transitions where a direct…
Rational boundary charge in one-dimensional systems with interaction and disorder
Mikhail Pletyukhov, Dante M. Kennes, Kiryl Piasotski +3
We study the boundary charge of generic semi-infinite one-dimensional insulators with translational invariance and show that non-local symmetries (i.e., including translation…
