Accurate autocorrelation modeling substantially improves fMRI reliability

Accurate autocorrelation modeling substantially improves fMRI reliability, Published online: 25 December 2019; doi:10.1038/s41467-019-09230-w

There has been recent controversy over the validity of commonly-used software packages for functional MRI (fMRI) data analysis. Here, the authors compare the performance of three leading packages (AFNI, FSL, SPM) in terms of temporal autocorrelation modeling, a key statistical step in fMRI analysis.

Kosterlitz-Thouless scaling at many-body localization phase transitions

By Philipp T. Dumitrescu, Anna Goremykina, Siddharth A. Parameswaran, Maksym Serbyn, and Romain Vasseur from Recent Articles in Phys. Rev. B. Published on Mar 22, 2019.

Author(s): Philipp T. Dumitrescu, Anna Goremykina, Siddharth A. Parameswaran, Maksym Serbyn, and Romain Vasseur

We propose a scaling theory for the many-body localization (MBL) phase transition in one dimension, building on the idea that it proceeds via a “quantum avalanche.” We argue that the critical properties can be captured at a coarse-grained level by a Kosterlitz-Thouless (KT) renormalization group (RG...

How do we map collective excitations with time, momentum, and energy resolution? Development of time-resolved resonant inelastic x-ray scattering (tr-RIXS) shows promise. Here, the authors present a theory for the tr-RIXS cross section, and as a proof of principle, they apply the theory to single-band models to elucidate the dynamics of particle-hole excitations. This work provides a crucial bridge for understanding how excitations from complicated phases manifest in time-resolved resonant scattering experiments.

Author(s): Ryuichi Ohta, Hajime Okamoto, Takehiko Tawara, Hideki Gotoh, and Hiroshi Yamaguchi

Mechanical vibration generates a time-varying strain that enables one to control the electrical and optical properties of solid-state two-level systems. Here, the authors report on a mechanical way to control exciton lifetimes using the vibrational strain of suspended semiconductor heterostructures. The results indicate a back-action force from the excitons to the mechanical resonator with this dissipative process, which has the potential to suppress the thermal noise of the resonator and provide a photon-exciton-phonon interaction in a solid-state system.

AuBe is a fascinating binary metal with a chiral structure predicted to host exotic fermions. Despite the polycrystalline nature of the samples, a plethora of de Haas–van Alphen oscillations is observed, one series of which shows a strongly field-dependent effective mass and Berry phase, supporting the premise of unusual fermions. Moreover, AuBe exhibits superconductivity with a highly enhanced resistive critical field. This property is shown to be intrinsic to this material class, implying that topologically protected surface states are involved.

Diagnosing phases of magnetic insulators via noise magnetometry with spin qubits

By Shubhayu Chatterjee, Joaquin F. Rodriguez-Nieva, and Eugene Demler from Recent Articles in Phys. Rev. B. Published on Mar 21, 2019.

Author(s): Shubhayu Chatterjee, Joaquin F. Rodriguez-Nieva, and Eugene Demler

Two-dimensional magnetic insulators exhibit a plethora of competing ground states, such as ordered (anti)ferromagnets, exotic quantum spin liquid states, and random singlet phases. Spin liquids, in particular, are collective phases of matter which have eluded discovery for several decades. Although there are many promising candidate materials for their realization, the central challenges for the clear diagnosis of a spin liquid has been the lack of experimental probes to access their emergent excitations. Here, the authors propose that spin qubit magnetometers grant access to these excitations and, therefore, can be used as a diagnostic of ground states in magnetic insulators.

Author(s): P. A. Nosov, I. M. Khaymovich, and V. E. Kravtsov

Conventional Anderson localization is due to destructive interference of matter waves described by local random Hamiltonians. Correlations in random diagonal elements of such a Hamiltonian are known to favor delocalization. Systems described by nonlocal Hamiltonians have become experimentally accessible recently. The authors consider two families of such random-matrix Hamiltonians with correlations in the long-range hopping terms and demonstrate that, as correlations become stronger, localization is enhanced while the wave-function ergodicity progressively deteriorates.

If the strong coupling is promoted to a dynamical field-dependent quantity, it is possible that the strong force looked very different in the early Universe. We consider a scenario in which the dynamics is such that QCD confines at high temperatures with a large dynamical scale, relaxing back to $∼1...

The number of known ferromagnetic Kondo lattices is significantly smaller than the number of antiferromagnetic ones. The former show remarkable physical traits such as, for instance, magnetic order along the hard axis of the crystal electric field. With a low Curie temperature and in the presence of Kondo correlations, YbIr3Ge7 provides an excellent opportunity to explore the interplay between strong magnetocrystalline anisotropy and magnetic fluctuations. It also serves as a good candidate material for tuning towards a rare ferromagnetic quantum critical point.
