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…
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…
