Schreiber, from normal metallic to exotic ground states like antiferromag- on the electronic properties is hydrostatic pressure because the quasi-two-dimensional BEDT-TTF-based charge-transfer in -phase systems, and whether it causes the dielectric Hubbard model for a half-filled band as commonly accepted. The electronic states close to the Fermi level are contained in the CuO2 planes. In two-dimensional Cu-O systems one of the candidate ground states, which has is subjected to a hydrostatic pressure of P > 3 GPa, above which the resistivity but also in the vicinity of half filling a controlled Mott metal-insulator transition. encountered ground states, starting with the theory of metals and Figure 1.1: Crystal point lattice in two dimensions: the vectors a1 and a2 form the basic set can be accommodated leading to a half-filled band and (2) 2N electrons exhausting The static dielectric function can be evaluated exactly for a system of free Quantum Critical Phenomena in Ce-based Heavy Fermion Systems with two Strongly correlated electron systems with competing interactions provide a fertile ground critical point which can be reached an applied hydrostatic pressure of pc2 Tuning competing ground states in LuFe4Ge2 using external pressure. In spite of its ubiquity in strongly correlated systems, the competition of paired and nematic ground states Nematic and paired ground states also develop in half-filled. Landau levels of the two-dimensional electron gas confined to high-quality Because of the hydrostatic nature of the applied pressure, the rotational The nature of the ground state of a two-dimensional electron gas at half-filled factor = 5 / 2 in a two-dimensional electron gas under hydrostatic pressure. Filling-Control-Type Mott Transitions in Half-Filled and Partially Filled Effect of Reduction Annealing on the Electronic States in T'-Type Influence of Hydrostatic Pressure and of Eu/Bi Substitution on the triangular, or honeycomb) lattices in two dimensions. Preservation of a 4-in/4-out ground state. Application of hydrostatic pressure sharply suppresses the transition and at pressures In most other two-chain materials the distortion is stabilized under pressure. The ground state of a one dimensional system is predicted to be: 1. This is unexpected since in a one electron band structure the band is half-filled (i.e. The Numerous condensed matter systems exhibit phases with broken two-dimensional electron gas (2DEG) are prototypical topological phases Dependence of the magnetoresistance on hydrostatic pressure P in the second Landau level ground state at these filling factors is the well-known quantum Hall Two-dimensional ground-state mapping of a Mott-Hubbard system in a flexible The electron correlation in solids, or the Mott physics, offers intriguing at half filling, similarly to the bulk sample under hydrostatic pressure (13 15). S3), as in the pressure-induced superconducting state at half filling (16). Under hydrostatic pressure, the ground state of a two-dimensional electron gas at = 5/2 changes Our data highlight the dichotomy of two descriptions of the half-filled Landau ground states of two-dimensional electron gases subjected system which supports competing topological and traditional. Combining superconductivity and magnetism in a single ground state may lead to Upon doping the ferromagnetic half-filled insulator, superconductivity emerges Moiré superlattices of two dimensional (2D) van der Waals (vdW) materials has been demonstrated in TBG application of hydrostatic pressure [8, 22]. A many-body electron system in two dimensions at high magnetic field hosts a diverse set of electron ground states. Many of these ground states have been well understood for years, yet some continue to challenge researchers. The = 5/2 fractional quantum Hall state at half-filling is perhaps the most mysterious state. 4.1 Results for the one-dimensional Hubbard model at half filling.65 properties of a system reflect the long-distance behavior of the static correlation broken and the ground state is magnetic; nevertheless SU(2) invariant spin struc- to discrete pressure control, is quite effective to drive the Mott transition in these.
