Revealing the nature of the charge density wave order of ErTe via Raman scattering under anisotropic strain
Theotime Freitas, Mattia Udina, Alexandr Alekhin +7
The nature of the charge density wave (CDW) order of the rare-earth tritelluride ErTe3 is investigated by Raman scattering under anisotropic strain. The CDW state of ErTe3 is uncon…
Hilbert space fragmentation imposed real spectrum of non-Hermitian systems
Somsubhra Ghosh, K. Sengupta, Indranil Paul
We show that constraints imposed by strong Hilbert space fragmentation (HSF) along with the presence of certain global symmetries can ensure the reality of eigenspectra of non-Herm…
Raman Response of the Charge Density Wave in Cuprate Superconductors
Moallison F. Cavalcante, S. Bag, I. Paul +3
We study the Raman response, for and light-polarization symmetries, of the charge density wave phase appearing in the underdoped region of cuprate superconductors…
Prethermal fragmentation in a periodically driven Fermionic chain
Somsubhra Ghosh, Indranil Paul, K. Sengupta
We study a Fermionic chain with nearest-neighbor hopping and density-density interactions, where the nearest-neighbor interaction term is driven periodically. We show that such a d…
Exceptional van Hove Singularities in Pseudogapped Metals
Indranil Paul, Marcello Civelli
Motivated by the pseudogap state of the cuprates, we introduce the concept of an "exceptional" van Hove singularity that appears when strong electron-electron interaction splits an…
Nematic fluctuations mediated superconductivity revealed by anisotropic strain in Ba(FeCo)As
J. -C. Philippe, A. Lespinas, J. Faria +7
Anisotropic strain is an external field capable of selectively addressing the role of nematic fluctuations in promoting superconductivity. We demonstrate this using polarization-re…
