Quasiparticle states driven by a scattering on the preformed electron pairs

Quasiparticle states driven by a scattering on the preformed electron pairs

We analyze evolution of the single particle excitation spectrum of the underdoped cuprate superconductors near the anti-nodal region, considering temperatures below and and above the phase transition. We inspect the phenomenological self-energy that reproduces the angle-resolved-photoemission-spectr...

We analyze evolution of the single particle excitation spectrum of the underdoped cuprate superconductors near the anti-nodal region, considering temperatures below and and above the phase transition. We inspect the phenomenological self-energy that reproduces the angle-resolved-photoemission-spectroscopy (ARPES) data and we show that above the critical temperature, such procedure implies a transfer of the spectral weight from the Bogoliubov-type quasiparticles towards the in-gap damped states. We also discuss some possible microscopic arguments explaining this process. Проаналiзовано еволюцiю спектру збудження однiєї частинки слабо легованих купратних надпровiдникiв поблизу антинодальної зони, беручи до уваги температури вищi i нижчi за фазовий перехiд. Дослiджено феноменологiчну самоенергiю, яка вiдтворює данi ARPES (кутової фотоемiсiйної спектроскопiї). Показано, що при температурах, вищих за критичну, така процедура передбачає перехiд спектральної ваги вiд квазiчастинок типу Боголюбова до загасаючих станiв всерединi щiлини.
