Effective model for PbCu(PO)O
Patrick A. Lee, Zhehao Dai
The copper substituted Pb-apatite has attracted a great deal of attention recently, due to the claim of the observation of room temperature superconductivity. Based on LDA calculat…
Fermionic Isometric Tensor Network States in Two Dimensions
Zhehao Dai, Yantao Wu, Taige Wang +1
We generalize isometric tensor network states to fermionic systems, paving the way for efficient adaptations of 1D tensor network algorithms to 2D fermionic systems. As the first a…
Photo-induced Superconductivity = Discrete Time Crystal?
Zhehao Dai, Vibhu Ravindran, Norman Y. Yao +1
We propose that periodic driving can stabilize a new type of order, "period-doubled superconductivity", in which a superconducting order parameter oscillates at half the frequency…
Superconducting-like response in driven systems near the Mott transition
Zhehao Dai, Patrick A. Lee
We point out that fractionalized bosonic charge excitations can explain the recently discovered photo-induced superconducting-like response in $κ\text{-(ET})_2\text{Cu}[\text{N(CN)…
Photo-induced superconducting-like response in strongly correlated systems
Zhehao Dai, Patrick A. Lee
We propose a novel mechanism for the photo-induced superconducting-like response recently reported in cuprates and other strongly correlated materials. This mechanism relies on qua…
Exploring Strongly Interacting Gapless States: Cuprates, Pair Density Waves, and Fluctuating Superconductivity
Zhehao Dai
We study the physical property of pair density wave (PDW) and fluctuating PDW, and use it to build an effective theory of the strongly interacting pseudogap phase in cuprate high t…
Quantum criticality of loops with topologically constrained dynamics
Zhehao Dai, Adam Nahum
Quantum fluctuating loops in 2+1 dimensions give gapless many-body states that are beyond current field theory techniques. Microscopically, these loops can be domain walls between…
Modeling the pseudogap metallic state in cuprates: quantum disordered pair density wave
Zhehao Dai, T. Senthil, Patrick A. Lee
We present a way to quantum-disorder a pair density wave, and propose it to be a candidate of the effective low-energy description of the pseudogap metal which may reveal itself in…
Pair density wave, charge density wave and vortex in high Tc cuprates
Zhehao Dai, Ya-Hui Zhang, T. Senthil +1
A recent scanning tunneling microscopy (STM) experiment reports the observation of charge density wave (CDW) with period of approximately 8a in the halo region surrounding the vort…
Optical Conductivity From Pair Density Waves
Zhehao Dai, Patrick A. Lee
We present a theory of optical conductivity in systems with finite-momentum Cooper pairs. In contrast to the BCS pairing where AC conductivity is purely imaginary in the clean limi…
