Quantum quench of the Sachdev-Ye-Kitaev Model
Andreas Eberlein, Valentin Kasper, Subir Sachdev +1
We describe the non-equilibrium dynamics of the Sachdev-Ye-Kitaev models of fermions with all-to-all interactions. These provide tractable models of the dynamics of quantum systems…
Thermal and electrical transport in metals and superconductors across antiferromagnetic and topological quantum transitions
Shubhayu Chatterjee, Subir Sachdev, Andreas Eberlein
We study thermal and electrical transport in metals and superconductors near a quantum phase transition where antiferromagnetic order disappears. The same theory can also be applie…
Fermi surface reconstruction and drop of Hall number due to spiral antiferromagnetism in high- cuprates
Andreas Eberlein, Walter Metzner, Subir Sachdev +1
We show that a Fermi surface reconstruction due to spiral antiferromagnetic order may explain the rapid change in the Hall number as recently observed near optimal doping in cuprat…
Shear viscosity at the Ising-nematic quantum critical point in two dimensional metals
Andreas Eberlein, Aavishkar A. Patel, Subir Sachdev
In an isotropic strongly interacting quantum liquid without quasiparticles, general scaling arguments imply that the dimensionless ratio , where is the shea…
Hyperscaling violation at the Ising-nematic quantum critical point in two dimensional metals
Andreas Eberlein, Ipsita Mandal, Subir Sachdev
Understanding optical conductivity data in the optimally doped cuprates in the framework of quantum criticality requires a strongly-coupled quantum critical metal which violates hy…
Thermodynamics of the two-dimensional XY model from functional renormalization
Pawel Jakubczyk, Andreas Eberlein
We solve the nonperturbative renormalization-group flow equations for the two-dimensional XY model at the truncation level of the (complete) second-order derivative expansion. We c…
Light induced enhancement of superconductivity via melting of competing bond-density wave order in underdoped cuprates
Aavishkar A. Patel, Andreas Eberlein
We develop a theory for light-induced superconductivity in underdoped cuprates in which the competing bond-density wave order is suppressed by driving phonons with light. Close to…
Self-energy effects in functional renormalization group flows of the two-dimensional - Hubbard model away from van Hove filling
Andreas Eberlein
We study the impact of the fermionic self-energy on one-loop functional renormalization group flows of the two-dimensional - Hubbard model, with emphasis on electronic densi…
Coexistence of incommensurate magnetism and superconductivity in the two-dimensional Hubbard model
Hiroyuki Yamase, Andreas Eberlein, Walter Metzner
We analyze the competition of magnetism and superconductivity in the two-dimensional Hubbard model with a moderate interaction strength, including the possibility of incommensurate…
Functional renormalization group for commensurate antiferromagnets: Beyond the mean-field picture
Stefan A. Maier, Andreas Eberlein, Carsten Honerkamp
We present a functional renormalization group (fRG) formalism for interacting fermions on lattices that captures the flow into states with commensurate spin-density wave order. Dur…
Functional renormalization group study of fluctuation effects in fermionic superfluids
Andreas Eberlein
This thesis is concerned with ground state properties of two-dimensional fermionic superfluids, in which fluctuation effects like the renormalization of the order parameter or infr…
Fermionic two-loop functional renormalization group for correlated fermions: Method and application to the attractive Hubbard model
Andreas Eberlein
We derive an efficient method for treating renormalization contributions at two-loop level within the functional renormalization group in the one-particle irreducible formalism for…
Competing order in correlated electron systems made simple: Consistent fusion of functional renormalization and mean-field theory
Jing Wang, Andreas Eberlein, Walter Metzner
We derive an efficient and unbiased method for computing order parameters in correlated electron systems with competing instabilities. Charge, magnetic and pairing fluctuations abo…
Superconductivity in the two-dimensional --Hubbard model
Andreas Eberlein, Walter Metzner
Using a recently developed renormalization group method for fermionic superfluids, we determine conditions for d-wave superconductivity in the two-dimensional Hubbard model at mode…
Effective interactions and fluctuation effects in spin-singlet superfluids
Andreas Eberlein, Walter Metzner
We derive and evaluate one-loop functional flow equations for the effective interactions, self-energy and gap function in spin-singlet superfluids. The flow is generated by a fermi…
Parametrization of Nambu vertex in a singlet superconductor
Andreas Eberlein, Walter Metzner
We analyze general properties of the effective Nambu two-particle vertex and its renormalization group flow in a spin-singlet superconductor. In a fully spin-rotation invariant for…
