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…
