Method of successive separation and summing of multiplicative diagrams of mass operator for the multi-level quasiparticle interacting with polarization phonons

open access: yesCondensed Matter Physics, 2019
The theory of renormalized energy spectrum of a multi-level quasiparticle interacting with polarization phonons at T = 0 K is developed within the Feynman-Pines diagram technique in a new approach.

Cyclotron Resonance and Quasiparticles [PDF]

open access: yesAIP Conference Proceedings, 2005
This introductory paper contains personal perspectives about the importance of cyclotron resonance in forming our modern view of solids. The papers following this one will discuss the discovery, refinements, and some of the latest developments. Although I will touch on some of these subjects, I leave the details to the other authors and in the main ...

Role of Spin in Quasiparticle Interference [PDF]

open access: yesPhysical Review Letters, 2004
Quasiparticle interference patterns measured by scanning tunneling microscopy can be used to study the local electronic structure of metal surfaces and high-temperature superconductors. Here, we show that even in nonmagnetic systems the spin of the quasiparticles can have a profound effect on the interference patterns.

Prolate-to-oblate transition and backbending along the yrast line induced by quasiparticle alignment

open access: yesPhysics Letters B, 2020
The yrast lines in Kr isotopes with N=42, 44, and 46 are investigated in a beyond mean field framework with both prolate-oblate coexistence and quasiparticle alignment taken into account.

Strong coupling Bose polarons in a two-dimensional gas

open access: yesPhysical Review Research, 2020
We study the properties of Bose polarons in two dimensions using quantum Monte Carlo techniques. Results for the binding energy, the effective mass, and the quasiparticle residue are reported for a typical strength of interactions in the gas and for a ...

Unveiling quasiparticle dynamics of topological insulators through Bayesian modelling

open access: yesCommunications Physics, 2021
Extracting quasiparticle dispersion from photoemission data is challenging and often results in confusion when investigating low-energy excitations.

The 3D split-ring cavity lattice: a new metastructure for engineering arrays of coupled microwave harmonic oscillators

open access: yesNew Journal of Physics, 2015
A new electromagnetic cavity structure, a lattice of 3D cavities consisting of an array of posts and gaps is presented. The individual cavity elements are based on the cylindrical re-entrant (or Klystron) cavity.

Electronic structure of the cuprate superconducting and pseudogap phases from spectroscopic imaging STM

open access: yes, 2014
We survey the use of spectroscopic imaging scanning tunneling microscopy (SI-STM) to probe the electronic structure of underdoped cuprates. Two distinct classes of electronic states are observed in both the d-wave superconducting (dSC) and the pseudogap (

Resonant wavepackets and shock waves in an atomtronic SQUID

open access: yesNew Journal of Physics, 2015
The fundamental dynamics of ultracold atomtronic devices are reflected in their phonon modes of excitation. We probe such a spectrum by applying a harmonically driven potential barrier to a ^23 Na Bose–Einstein condensate in a ring-shaped trap.
