“…Similar effects can also occur in systems with more orbitals. With the symmetry breaking perturbations, a cutoff scale ∆ c is introduced to the RG flow in the nonlinear sigma model description [65]. A nonzero critical temperature appears and takes a suppressed form…”

We show that the large orbital degeneracy inherent in Moiré heterostructures naturally gives rise to a 'high-Tc' like phase diagram with a chiral twist -wherein an exotic quantum anomalous Hall insulator phase is flanked by chiral d + id superconducting domes. Specifically, we analyze repulsively interacting fermions on hexagonal (triangular or honeycomb) lattices near Van Hove filling, with an SU(N f ) flavor degeneracy. This model is inspired by recent experiments on graphene Moiré heterostructures. At this point, a nested Fermi surface and divergent density of states give rise to strong (ln 2 ) instabilities to correlated phases, the competition between which can be controllably addressed through a combination of weak coupling parquet renormalization group and Landau-Ginzburg analysis. For N f = 2 (i.e. spin degeneracy only) it is known that chiral d + id superconductivity is the unambiguously leading weak coupling instability. Here we show that N f ≥ 4 leads to a richer (but still unambiguous and fully controllable) behavior, wherein at weak coupling the leading instability is to a fully gapped and chiral Chern insulator, characterized by a spontaneous breaking of time reversal symmetry and a quantized Hall response. Upon doping this phase gives way to a chiral d + id superconductor. We further consider deforming this minimal model by introducing an orbital splitting of the Van Hove singularities, and discuss the resulting RG flow and phase diagram. Our analysis thus bridges the minimal model and the practical Moiré band structures, thereby providing a transparent picture of how the correlated phases arise under various circumstances. Meanwhile, a similar analysis on the square lattice predicts a phase diagram where (for N f > 2) a nodal staggered flux phase with 'loop current' order gives way upon doping to a nodal d-wave superconductor.

“…Thus, we have to essentially find local sections of the zero temperature instanton solutions Eq. (17), that are additionally periodic by nβ in the x 4 direction. For such viable solutions to exist, we must have 2R ≥ nβ, as is clear from geometry.…”

“…The formalism was, for instance, leveraged to compute pair-production rates for magnetic monopoles at strong coupling [4,7]. With the development of string theoretic techniques towards understanding gauge theory scattering amplitudes [15][16][17][18][19], the method found further resurgence and applications (see for example [20] and related references); particularly, in our context, conveniently accommodating computations with large external fields [21][22][23][24][25].…”

We compute Schwinger pair production rates at finite temperature, in the presence of homogeneous, concurrent electric and magnetic fields. Expressions are obtained using the semiclassical worldline instanton formalism, to leading order, for spin-0 and spin-1 2 particles. The derived results are valid for weak coupling and fields. We thereby extend previous seminal results in the literature, to coexistent electric and magnetic fields, and fermions. * mrunal.korwar@students.iiserpune.ac.in † thalapillil@iiserpune.ac.in arXiv:1808.01295v3 [hep-th]

“…Various features are shared between the QDM and Q6VM. For v < 1 the ground states in the square lattice are broken symmetry phases, in which the charges are confined from the gauge theory point of view [13]. For v = 1, the Hamiltonian realizes the celebrated RK point, at which a soft quadratically dispersing photon mode appears.…”

Solving the quantum dimer and six-vertex models one electric field line at a time

The nature and the very existence of the resonant plaquette valence bond state that separates the classical columnar phase and the Rokhsar-Kivelson point in the quantum dimer model remains unsettled. Here we take a different line of attack on this model, and on the closely related six-vertex model, by exploiting the global conservation law of the number of electric field lines. This allows us to study a single fluctuating electric field line which we show maps exactly onto a one-dimensional spin chain. In the case of the six-vertex model, the electric field line maps onto the celebrated spin 1/2 XXZ model which can be solved exactly. In the quantum dimer model, the electric field line is mapped onto a two-leg spin 1/2 ladder, which we study using numerical exact diagonalization. Our findings are consistent with the existence of three distinct phases including a Luttinger liquid phase, the one-dimensional precursor to the two-dimensional plaquette valence bond solid. The uncanny resemblance of our quasi-one-dimensional electric field line problem to the full two-dimensional problem suggests that much of the behavior of the latter might be understood by thinking of it as a closely packed array of field lines which themselves are undergoing nontrivial phase transitions. arXiv:1902.01858v2 [cond-mat.str-el]
