Universally diverging Grueneisen parameter and the magnetocaloric effect close to quantum critical points
Lijun Zhu, Markus Garst, Achim Rosch +1
At a generic quantum critical point, the thermal expansion is more singular than the specific heat . Consequently, the "Grüneisen ratio'', $\GE=α/c_p$, diverges. When scal…
Local quantum critical point and non-Fermi liquid properties
Qimiao Si
Quantum criticality provides a means to understand the apparent non-Fermi liquid phenomena in correlated electron systems. How to properly describe quantum critical points in elect…
Hall Effect in Nested Antiferromagnets Near the Quantum Critical Point
M. R. Norman, Qimiao Si, Ya. B. Bazaliy +1
We investigate the behavior of the Hall coefficient in the case of antiferromagnetism driven by Fermi surface nesting, and find that the Hall coefficient should abruptly increase w…
Photo-thermal transitions of magneto-excitons in quantum wells
J. Cerne, J. Kono, M. Su +1
By monitoring changes in excitonic photoluminescence (PL) that are induced by terahertz (THz) radiation, we observe resonant THz absorption by magnetoexcitons in GaAs/AlGaAs quantu…
Permutation-Symmetric Multicritical Points in Random Antiferromagnetic Spin Chains
Kedar Damle, David A. Huse
The low-energy properties of a system at a critical point may have additional symmetries not present in the microscopic Hamiltonian. This letter presents the theory of a class of m…
Locally critical point in an anisotropic Kondo lattice
D. R. Grempel, Qimiao Si
We report the first numerical identification of a locally quantum critical point, at which the criticality of the local Kondo physics is embedded in that associated with a magnetic…
Critical local moment fluctuations in the Bose-Fermi Kondo model
Lijun Zhu, Qimiao Si
We consider the critical properties of the Bose-Fermi Kondo model, which describes a local moment simultaneously coupled to a conduction electron band and a fluctuating magnetic fi…
Local fluctuations in quantum critical metals
Qimiao Si, Silvio Rabello, Kevin Ingersent +1
We show that spatially local, yet low-energy, fluctuations can play an essential role in the physics of strongly correlated electron systems tuned to a quantum critical point. A de…
