Role of Phase Fluctuation in Dynamic Competition Between Charge Order and Superconductivity in Cuprates
Mingu Kang, Pavel E. Dolgirev, Chao C. Zhang +9
Phase fluctuations are a key factor distinguishing nonthermal (ultrafast) and thermal phase transitions. Charge order in cuprates is characterized by short-range coherence while co…
Time-domain identification of distinct mechanisms for competing charge density waves in a rare-earth tritelluride
Yifan Su, B. Q. Lv, Alfred Zong +11
Understanding the origin of phase transitions and the interactions between distinct phases remains a central task in condensed matter physics. Charge density wave (CDW) systems pro…
Two-dimensional spectroscopy of bosonic collective excitations in disordered many-body systems
Alex Gómez Salvador, Ivan Morera, Marios H. Michael +5
We present a novel theoretical approach for computing and analyzing two-dimensional spectroscopy of bosonic collective excitations in disordered many-body systems. Specifically, we…
Optical signatures of interlayer electron coherence in a bilayer semiconductor
Xiaoling Liu, Nadine Leisgang, Pavel E. Dolgirev +10
Emergent strongly-correlated electronic phenomena in atomically-thin transition metal dichalcogenides are an exciting frontier in condensed matter physics, with examples ranging fr…
Local noise spectroscopy of Wigner crystals in two-dimensional materials
Pavel E. Dolgirev, Ilya Esterlis, Alexander A. Zibrov +3
We propose to use local electromagnetic noise spectroscopy as a versatile and noninvasive tool to study Wigner crystal phases of strongly-interacting two-dimensional electronic sys…
Optically-induced Umklapp shift currents in striped cuprates
Pavel E. Dolgirev, Marios H. Michael, Jonathan B. Curtis +6
Motivated by recent experiments that observed low-frequency second-order optical responses in doped striped superconductors, here we investigate the nonlinear electrodynamics of sy…
Dynamical slowing down in an ultrafast photo-induced phase transition
Alfred Zong, Pavel E. Dolgirev, Anshul Kogar +20
Complex systems, which consist of a large number of interacting constituents, often exhibit universal behavior near a phase transition. A slowdown of certain dynamical observables…
Pseudogap and Fermi surface in the presence of spin-vortex checkerboard for 1/8-doped lanthanum cuprates
Pavel E. Dolgirev, Boris V. Fine
Lanthanum family of high-temperature cuprate superconductors is known to exhibit both spin and charge electronic modulations around doping level 1/8. We assume that these modulatio…
