Tunneling spectra of impurity states in unconventional superconductors
P. O. Sukhachov, Felix von Oppen, L. I. Glazman
We investigate the role of the Bloch functions and superconducting gap symmetries on the formation and properties of impurity-induced resonances in a two-dimensional superconductor…
Andreev Reflection in Scanning Tunneling Spectroscopy of Unconventional Superconductors
P. O. Sukhachov, Felix von Oppen, L. I. Glazman
We evaluate the differential conductance measured in a scanning tunneling microscopy (STM) setting at arbitrary electron transmission between an STM tip and a two-dimensional (2D)…
Bose-Einstein condensate of Dirac magnons: Pumping and collective modes
P. O. Sukhachov, S. Banerjee, A. V. Balatsky
We explore the formation and collective modes of Bose-Einstein condensate of Dirac magnons (Dirac BEC). While we focus on two-dimensional Dirac magnons, an employed approach is gen…
Non-Hermitian impurities in Dirac systems
P. O. Sukhachov, A. V. Balatsky
Quasiparticle states in Dirac systems with complex impurity potentials are investigated. It is shown that an impurity site with loss leads to a nontrivial distribution of the local…
Quantum Pairing Time Orders
A. V. Balatsky, P. O. Sukhachov, S. Bandyopadhyay
We propose the concept of the time-independent correlators for the even- and odd-frequency pairing states that can be defined for both bosonic and fermionic quasiparticles. These c…
Spectroscopic and optical response of odd-frequency superconductors
P. O. Sukhachov, A. V. Balatsky
The optical response of superconductors with odd-frequency Berezinskii pairing is studied. By using a simple model with a parabolic dispersion law and a non-magnetic disorder, the…
Gap generation in Weyl semimetals in a model with local four-fermion interaction
P. O. Sukhachov
We study the gap generation in Weyl semimetals in a model with local four-fermion interaction. It is shown that there exists a critical value of coupling constant separating the sy…
