Two-lifetime model for the cuprates revisited

František Herman, Lucia Gelenekyová, Hana Havranová +1

Several models of the strange-metal state of the cuprate superconductors postulate the existence of strong inelastic forward scattering of the electrons, but direct evidence of suc…

Local Limit Disorder Characteristics of Superconducting Radio Frequency Cavities

Anastasiya Lebedeva, Matúš Hladký, Marcel Polák +1

Nowadays Nb-based superconducting radio-frequency cavities represent fundamental tools used for (Standard Model) particle acceleration, (beyond Standard Model) particle probing, an…

Detailed Analysis of the Superconducting Gap with Dynes Pair-Breaking Scattering

Anastasiya Lebedeva, František Herman

We study the energy gap within the Dynes superconductor theory. This model generalizes the Bardeen-Cooper-Schrieffer (BCS) approach by including the pair-breaking scattering, intro…

Advanced approach of superconducting gap function extraction from tunneling experiments

František Herman

An advanced theoretical framework is introduced and examined. Its main idea is to extract properties of the superconducting pairing gap function in the conventional, nearly…

Automated reconstruction of bound states in bilayer graphene quantum dots

Jozef Bucko, Frank Schäfer, František Herman +5

Bilayer graphene is a nanomaterial that allows for well-defined, separated quantum states to be defined by electrostatic gating and, therefore, provides an attractive platform to c…

Model-independent determination of the gap function of nearly localized superconductors

Dušan Kavický, František Herman, Richard Hlubina

The gap function carries essential information on both, the pairing glue as well as the pair-breaking processes in a superconductor. Unfortunately, in nearly localized super…

Magnetotransport of dirty-limit van Hove singularity quasiparticles

Yang Xu, František Herman, Veronica Granata +13

Tuning of electronic density-of-states singularities is a common route to unconventional metal physics. Conceptually, van Hove singularities are realized only in clean two-dimensio…

Excited states in bilayer graphene quantum dots

A. Kurzmann, M. Eich, H. Overweg +11

We report on ground- and excited state transport through an electrostatically defined few-hole quantum dot in bilayer graphene in both parallel and perpendicular applied magnetic f…

Deviation from the Fermi-Liquid Transport Behavior in the Vicinity of a Van Hove Singularity

František Herman, Jonathan Buhmann, Mark H Fischer +1

Recent experiments revealed non-Fermi-liquid resistivity in the unconventional superconductor SrRuO when strain pushes one of the Fermi surfaces close to a van Hove sin…

Thermodynamic properties of the Dynes superconductors

Frantisek Herman, Richard Hlubina

The tunneling density of states in dirty superconductors is often well described by the phenomenological Dynes formula. Recently we have shown that this formula can be derived, wit…

Consistent two-lifetime model for spectral functions of superconductors

František Herman, Richard Hlubina

Recently it has been found that models with at least two lifetimes have to be considered when analyzing the angle resolved photoemission data in the nodal region of the cuprates [T…

Microscopic interpretation of the Dynes formula for the tunneling density of states

Frantisek Herman, Richard Hlubina

Excellent fits of the tunneling density of states in disordered superconductors can be often achieved making use of the phenomenological Dynes formula. However, no consistent deriv…
