• W2044817094 abstract "We analyze charge order within the the spin-fermion model. We show that magnetically-mediated interaction gives rise to charge order $Delta_k^Q = langle c^dagger_{{bf k}+{bf Q}} c_{{bf k}-{bf Q}}rangle$ with momenta ${bf Q}=Q_x =(2Q,0)$ and ${bf Q}=Q_y =(0,2Q)$, if the magnetic correlation length $xi$ exceeds some critical value. We argue that $Delta_k^Q$ and $Delta_{-k}^Q$ are not equivalent, and their symmetric and antisymmetric combinations describe density modulations and bond current. We derive GL functional for four-component $U(1)$ order parameters $Delta^Q_{pm k}$ with ${bf Q} = Q_x$ or $Q_y$. Within mean-field we find two types of CDW states, I and II, depending on system parameters. In state I density and current modulations emerge with the same ${bf Q} = Q_x$ or $Q_y$, breaking $Z_2$ lattice rotational symmetry, and differ in phase by $pmpi/2$. The selection of $pi/2$ or $-pi/2$ additionally breaks $Z_2$ time-reversal symmetry, such that the total order parameter manifold is $U(1) times Z_2 times Z_2$. In state II density and current modulations emerge with different $bf Q$ and the order parameter manifold is $U(1) times U (1) times Z_2$. We go beyond mean-field and show that discrete symmetries get broken before long-range charge order sets in. For state I, the system first breaks $Z_2$ lattice rotational symmetry ($C_4 to C_2$) at $T= T_n$ and develops a nematic order, then breaks $Z_2$ time-reversal symmetry at $T_t < T_n$, and finally breaks $U(1)$ symmetry of a common phase of even and odd components of $Delta^Q_{k}$ at $T= T_{rm cdw} < T_t < T_n$ and develops a true charge order. We argue that the preemptive orders lift $T_{rm cdw}$ and reduces $T_{rm sc}$ such that at large $xi$ charge order may develop prior to superconductivity. We obtain the phase diagram and present quantitative comparison with ARPES data for hole-doped cuprates." @default.
