Magnetic excitations of the strongly-anisotropic triangular XXZ model: a projected spin-product state approach
Achille Mauri, Frédéric Mila
Recent experiments have sparked interest on the ground-state properties and on the excitation spectrum of the spin- triangular XXZ model with strong Ising-like anisotropy. In…
Non-linear spin wave theory in the strong easy-axis limit of the triangular XXZ model
Achille Mauri, Siebe Roose, Frédéric Mila
Motivated by recent experimental studies, we investigate the spectrum of the nearest-neighbour triangular XXZ model within the expansion, in the limit in which the exchange c…
Slow convergence of spin-wave expansion and magnon dispersion in the 1/3 plateau of the triangular XXZ antiferromagnet
Achille Mauri, Frédéric Mila
Motivated by recent experiments on the quantum magnet KCo(SeO), we study theoretically the excitation spectrum of the nearest-neighbour triangular XXZ model in th…
Frustrated magnets in the limit of infinite dimensions: dynamics and disorder-free glass transition
Achille Mauri, Mikhail I. Katsnelson
We study the statistical mechanics and the equilibrium dynamics of a system of classical Heisenberg spins with frustrated interactions on a -dimensional simple hypercubic lattic…
Perturbative renormalization and thermodynamics of quantum crystalline membranes
Achille Mauri, Mikhail I. Katsnelson
We analyze the statistical mechanics of a free-standing quantum crystalline membrane within the framework of a systematic perturbative renormalization group (RG). A power-counting…
Scale without conformal invariance in membrane theory
Achille Mauri, Mikhail I. Katsnelson
We investigate the relation between dilatation and conformal symmetries in the statistical mechanics of flexible crystalline membranes. We analyze, in particular, a well-known mode…
Thermal ripples in bilayer graphene
Achille Mauri, David Soriano, Mikhail I. Katsnelson
We study thermal fluctuations of a free-standing bilayer graphene subject to vanishing external tension. Within a phenomenological theory, the system is described as a stack of two…
Scaling behavior of crystalline membranes: an -expansion approach
Achille Mauri, Mikhail I. Katsnelson
We study the scaling behavior of two-dimensional (2D) crystalline membranes in the flat phase by a renormalization group (RG) method and an -expansion. Generalization of the pro…
Dielectric function and plasmons of doped three-dimensional Luttinger semimetals
Achille Mauri, Marco Polini
Luttinger semimetals are three-dimensional electron systems with a parabolic band touching and an effective total spin . In this paper, we present an analytical theory of di…
Interplay between in-plane and flexural phonons in electronic transport of two-dimensional semiconductors
A. N. Rudenko, A. V. Lugovskoi, A. Mauri +3
Out-of-plane vibrations are considered as the dominant factor limiting the intrinsic carrier mobility of suspended two-dimensional materials at low carrier concentrations. Anharmon…
Thermal fluctuations in crystalline membranes with long-range dipole interactions
Achille Mauri, Mikhail I. Katsnelson
We study the effects of long-range electrostatic interactions on the thermal fluctuations of free-standing crystalline membranes exhibiting spontaneous electric polarization direct…
