We study the critical behavior and the ground-state entanglement of a large class of su(1|1) supersymmetric spin chains with a general (not necessarily monotonic) dispersion relation. We show that this class includes several relevant models, with both short- and long-range interactions of a simple form. We determine the low temperature behavior of the free energy per spin, and deduce that the models considered have a critical phase in the same universality class as a (1+1)-dimensional conformal field theory (CFT) with central charge equal to the number of connected components of the Fermi sea...

This study utilized a mixed methods approach to examine the feasibility and acceptability of group compassion focused therapy for adults with intellectual disabilities (CFT-ID). Six participants with mild ID participated in six sessions of group CFT, specifically adapted for adults with ID. Session-by-session feasibility and acceptability measures suggested that participants understood the group content and process and experienced group sessions and experiential practices as helpful and enjoyable. Thematic analysis of focus groups identified three themes relating to (1) direct experiences of the group, (2) initial difficulties in being self-compassionate and (3) positive emotional changes...

Diabetes mellitus often results in a number of complications involving impaired brain function, including cognitive deficits and depression. However, the potential mechanisms for diabetes-related cognitive deficits and depression are not fully understood. Neurons in the hippocampal, cortical and amygdala functional regions are more susceptible to damage during hyperglycemia. Neuroprotection in the brain can rescue cognitive deficits and depression induced by hyperglycemia. This study investigated the potential mechanisms underlying diabetes-related congnitive deficits and depression, determined whether the inflammatory factor inducible nitric oxide synthase (iNOS) and the nitric oxide (NO)/soluble guanylyl cyclases (sGC)/cyclic guanosine monophosphate (cGMP)/protein kinase G (PKG) pathway, play key roles in cognitive deficits and depression associated...

Assigning a chaos index for dynamics of generic quantum field theories is a challenging problem because the notion of a Lyapunov exponent, which is useful for singling out chaotic behavior, works only in classical systems. We address the issue by using the AdS/CFT correspondence, as the large N_{c} limit provides a classicalization (other than the standard ℏ→0) while keeping nontrivial quantum condensation. We demonstrate the chaos in the dynamics of quantum gauge theories: The time evolution of homogeneous quark condensates ⟨q[over ¯]q⟩ and ⟨q[over ¯]γ_{5}q⟩ in an N=2 supersymmetric QCD with the SU(N_{c}) gauge group at large N_{c} and at a large 't Hooft coupling λ≡N_{c}g_{YM}^{2} exhibits a positive Lyapunov exponent...
