Superfluid density in cuprates: hints on gauge compositeness of the holes
P. A. Marchetti, G. Bighin
We show that several features (the three-dimensional XY universality for moderate underdoping, the almost-BCS behaviour for moderate overdoping and the critical exponent) of the su…
Universality in cuprates: a gauge approach
P. A. Marchetti, G. Bighin
In high- cuprates many quantities exhibit a non-Fermi liquid universality hinting at a very peculiar structure of the underlying pairing mechanism for superconductivity: in th…
Beliaev damping of the Goldstone mode in atomic Fermi superfluids
G. Bighin, L. Salasnich, P. A. Marchetti +1
Beliaev damping in a superfluid is the decay of a collective excitation into two lower frequency collective excitations; it represents the only decay mode for a bosonic collective…
Gauge approach to superfluid density in underdoped cuprates
P. A. Marchetti, G. Bighin
We prove that a gauge approach based on a composite structure of the hole in hole-doped cuprates is able to capture analytically many features of the experimental data on superflui…
Interplay of superconductivity and magnetism in a t-t'-J approach to high Tc cuprates
P. A. Marchetti
We review a recently proposed mechanism for superconductivity in hole-doped cuprates exhibiting a strong interplay between pairing and antiferromagnetism. Starting from the t-t'-J…
A gauge approach to the "pseudogap" phenomenology of the spectral weight in high Tc cuprates
P. A. Marchetti, M. Gambaccini
We assume the t-t'-J model to describe the CuO_2 planes of hole-doped cuprates and we adapt the spin-charge gauge approach, previously developed for the t-J model, to describe the…
Variational principle and energy-momentum tensor for relativistic Electrodynamics of point charges
K. Lechner, P. A. Marchetti
We give a new representation as tempered distribution for the energy-momentum tensor of a system of charged point-particles, which is free from divergent self-interactions, manifes…
Anomaly free effective action for the elementary M5-brane
K. Lechner, P. A. Marchetti, M. Tonin
We construct an effective action describing an elementary M5-brane interacting with dynamical eleven-dimensional supergravity, which is free from gravitational anomalies. The curre…
Spin-statistics transmutation in relativistic quantum field theories of dyons
K. Lechner, P. A. Marchetti
We analyse spin and statistics of quantum dyon fields, i.e. fields carrying both electric and magnetic charge, in 3+1 space-time dimensions. It has been shown long time ago that, a…
Interacting branes, dual branes, and dyonic branes: a unifying lagrangian approach in D dimensions
K. Lechner, P. A. Marchetti
This paper presents a general covariant lagrangian framework for the dynamics of a system of closed n-branes and dual (D-n-4)-branes in D dimensions, interacting with a dynamical (…
Algebraic-geometrical formulation of two-dimensional quantum gravity
G. Bonelli, P. A. Marchetti, M. Matone
We find a volume form on moduli space of double punctured Riemann surfaces whose integral satisfies the Painlevé I recursion relations of the genus expansion of the specific heat o…
Nonperturbative 2D Gravity, Punctured Spheres and -Vacua in String Theories
G. Bonelli, P. A. Marchetti, M. Matone
We consider a model of 2D gravity with the coefficient of the Einstein-Hilbert action having an imaginary part . This is equivalent to introduce a -vacuum structure in the…
