Self-trapped excitons (STEs) have attracted tremendous attention due to their intriguing
properties and potential optoelectronic applications. STEs are formed from the lattice …

SrRuO 3 is endowed with three remarkable features. First, it is a moderately correlated
material that exhibits several novel physical properties; second, it permits the epitaxial …

While basic features of polarons were well recognized a long time ago and have been
described in a number of review papers and textbooks, interest in the role of electron …

We have performed a systematic do**-dependent study of La 2− x Sr x Cu O 4
(LSCO)(0.03⩽ x⩽ 0.3) by angle-resolved photoemission spectroscopy. Over this entire …

The large variations in T c across the cuprate families is one of the major unsolved puzzles
in condensed matter physics and is poorly understood. Although there appears to be a great …

We have performed a systematic angle-resolved photoemission spectroscopy (ARPES)
study of the high-T c cuprates La 2− x Sr x CuO 4, ranging from the underdoped insulator to …

Photoinduced transitions from a Mott insulator to a metal have been investigated in the
undoped cuprates Nd 2 CuO 4 and La 2 CuO 4 by applying femtosecond pump-probe …

Antiferromagnetism (AFM) such as Néel ordering is often closely related to Coulomb
interactions such as Hubbard repulsion in two-dimensional (2D) systems. Whether Néel …

Charge and lattice dynamics caused by photocarrier do** of the undoped cuprates Nd 2
CuO 4 and La 2 CuO 4 were studied by femtosecond absorption spectroscopy. In both …

We recently unveiled that antiferromagnetism (AFM) order can be dominantly induced by the
bond Su-Schrieffer-Heeger (SSH) electron-phonon coupling (EPC), which is beyond the …
