Pressure dependence of the single particle excitation in the charge-density-wave CeTe system
M. Lavagnini, A. Sacchetti, C. Marini +8
We present new data on the pressure dependence at 300 K of the optical reflectivity of CeTe, which undergoes a charge-density-wave (CDW) phase transition well above room temper…
Two-level Physics in a Model Metallic Break Junction
P. Lucignano, G. E. Santoro, M. Fabrizio +1
We consider a model inspired by a metal break-junction hypothetically caught at its breaking point, where the non-adiabatic center-of-mass motion of the bridging atom can be treate…
Magnetic field-induced transition in a quantum magnet described by the Quantum Dimer Model
A. Ralko, F. Becca, D. Poilblanc
The effect of a magnetic field on a gapped quantum magnet is described within the framework of the Quantum Dimer Model. A minimal model describing the proliferation of itinerant sp…
Role of backflow correlations for the non-magnetic phase of the t-t' Hubbard model
Luca F. Tocchio, Federico Becca, Alberto Parola +1
We introduce an efficient way to improve the accuracy of projected wave functions, widely used to study the two-dimensional Hubbard model. Taking the clue from the backflow contrib…
Correlation effects in quasi one dimensional electron wires
L. Shulenburger, M. Casula, G. Senatore +1
We explore the role of electron correlation in quasi one dimensional quantum wires as the range of the interaction potential is changed and their thickness is varied by performing…
Time-dependent Gutzwiller theory of pairing fluctuations in the Hubbard model
G. Seibold, F. Becca, J. Lorenzana
We present a method to compute pairing fluctuations on top of the Gutzwiller approximation (GA). Our investigations are based on a charge-rotational invariant GA energy functional…
