ARPES in strongly disordered systems -- theory of electronic bands melting
Piotr Chudzinski, Lenart Dudy
It is well known that translational symmetry-breaking disorder will disrupt ARPES spectra up to the point where they become invisible. However, a theoretical framework to capture t…
Parameters of Tomonaga-Luttinger liquid in a quasi-1D material with Coulomb interactions
P. Chudzinski
In this work we derive a new scheme to calculate Tomonaga-Luttinger liquid (TLL) parameters and holon (charge modes) velocities in a quasi-1D material that consists of two-leg ladd…
Anharmonic coupling between electrons and TO phonons in the vicinity of ferroelectric quantum critical point
P. Chudzinski
We explore a novel coupling mechanism of electrons with the transverse optical (TO) phonon branch in a regime when the TO mode becomes highly anharmonic and drives the ferroelectri…
Slow quenches in XXZ spin-chains -- the role of Galilean invariance breaking
P. Chudzinski
We study a XXZ spin-chain in a gapless Tomonaga-Luttinger liquid (TLL) phase with time dependent anisotropy of spin exchange interactions. To begin we focus on a linear ramp of $J_…
Multi-orbital physics in lithium-molybdenum purple-bronze: going beyond paradigm
P. Chudzinski
We investigate the role of inter-orbital fluctuations in the low energy physics of a quasi-1D material - lithium molybdenum purple bronze (LMO). It is an exceptional material that…
Time evolution during and after finite-time quantum quenches in Luttinger liquids
Piotr Chudzinski, Dirk Schuricht
We consider finite-time quantum quenches in the interacting Tomonaga--Luttinger model, for example time-dependent changes of the nearest-neighbour interactions for spinless fermion…
