Because the transition is generally accompanied by both magnetic and charge-order instabilities, it remains unclear if a continuous Wigner-Mott transition exists. Here, we demonstrate bandwidth-tuned … cal royal bb5200 nrp

Nettettic phase to stripe-crystal order in the absence of shape fluctuations means that along the x-axis, the system is always crystalline; a stripe crystal for ν near M + 1/2 and a Wigner crystal for smaller ν. For ν = M + 1/2, the smectic phase is marginally stable, due to particle-hole symmetry, or equivalently, due to the fact that the code softwares
